WSET Level 2 Sake Exam: Complete Revision Guide and Practice Examinations

A good revision answer does more than name kōji. It explains what kōji supplies, what those enzymes do and why a brewer might manage them differently. The WSET Level 2 Sake exam rewards connected knowledge across production, classifications and service. This final lesson turns that knowledge into a practical revision plan, then offers two complete original mock examinations.

This is an independent TFE resource without WSET endorsement. The questions below are original teaching items, not official examination questions or predictions of a future paper. Passing a mock is useful evidence about the topics tested here; it does not guarantee a pass in the official assessment.

WSET Level 2 Sake exam: know the actual assessment

The official specification, Issue 1 (2024) sets a closed-book theory examination of 50 multiple-choice questions in 60 minutes. Each question has one correct answer and earns one mark. There is no negative marking. There is no separately assessed practical tasting examination.

The official outcome distribution is 25 questions on ingredients and production, 20 on categories, grades and specialty styles, and 5 on storage, service and pairing. Both original mocks use that exact 25/20/5 structure. The sections are ordered by outcome so you can diagnose weak areas after marking.

The percentage bands start at 55% for Pass, 70% for Merit and 85% for Distinction. With 50 whole-mark questions, the corresponding starting scores are 28/50, 35/50 and 43/50. Read current assessment instructions from your provider as well: this collection follows the identified specification, and no particular provider has been identified for independent course-version verification.

Revision should follow the material through the brewery

Begin with steamed white rice, kōji, water and yeast. The rice supplies starch; kōji supplies enzymes; yeast ferments available sugars into alcohol and carbon dioxide; water helps establish the environment. Optional jōzō alcohol and starter lactic acid have specific roles. Glucose, acids and amino acids are broader optional additions for futsū-shu, not universal premium ingredients.

Review rice as Japonica, short-grained and non-glutinous in the syllabus sense. Both table rice and sake-specific rice can be used. Yamada-nishiki, Gohyakuman-goku and Miyama-nishiki are the three required variety names. Connect large grains, suitable strength and useful digestibility to what the brewery can do, rather than assigning each variety one compulsory flavor.

The husk protects the grain; bran and germ differ in composition from the starch-rich endosperm. The germ is the embryo, while shinpaku is an opaque white core, not a pocket of finished sugar. Growing moves through seedling establishment, plant development, flowering, grain filling, ripening and harvest. Conditions in the field can affect the material the brewer receives.

Preparation changes access and composition

Polishing removes outer material and changes the balance of components remaining. Seimai-buai means the proportion of brown-rice weight left after polishing. For a 250-kilogram lot at 60%, 150 kilograms nominally remain and 100 are removed. Keep remaining and removed in separate columns when practicing calculations.

Washing clears surface residue, while soaking manages water uptake. Steaming gelatinises hydrated starch, preparing it for enzyme action. Batch and continuous steaming are equipment arrangements serving the same aim of appropriate rice condition. Cooling then connects physical preparation to the requirements of cultivation or fermentation.

Do not turn a lower polishing figure into an automatic quality score. It changes material and cost, but the intended style still has to be achieved. A fuller sake can be a deliberate success, not a failed attempt to become the most delicate possible drink.

Kōji supplies several activities, not one vague fermentation power

Amylases help convert starch into smaller carbohydrates and glucose. Other enzyme activity breaks proteins into peptides and amino acids, contributing to nutrition and savory potential. The syllabus also includes a colour contribution. Warmth, humidity, rice moisture and the culture all matter to the outcome.

Follow cooling, establishing mould growth, managing it and stopping at the selected endpoint. Growing mould produces heat, so mixing, spreading and managing trays can control internal conditions. Hand, partially machine-made and fully machine-made methods organize this control differently. Stopping cultivation does not mean eliminating all the enzymes needed later.

Sō-haze has extensive growth and can support broader enzyme and nutrient contributions. Tsuki-haze has localized surface growth with penetration and commonly supports restrained ginjō plans. These are cultivation patterns, not legal premium grades. Their role is best explained through the fermentation they help prepare.

Water, yeast and starters establish the working population

Mineral composition can support fermentation, while iron is undesirable because of its adverse sensory and colour effects. Hardness is useful information but not a complete water assessment. Different supplies can be managed successfully; soft water doesn’t mean a brewery cannot make sake.

Remember 7 as the reliable-fermenter reference, 9 as an early ginjō yeast and 1801 as a later aromatic option. For ginjō aromas, link five factors: nutrient levels, polishing, kōji style, temperature and strain. Yeast capability needs an appropriate environment; a strain number alone does not certify one taste.

The shubo or moto develops an active yeast population. Sokujō adds lactic acid directly. Kimoto and yamahai use lactic acid bacteria to supply acidity; kimoto includes yamaoroshi, while yamahai omits it. Acidification discourages competitors without making hygiene unnecessary. Richness is a common association of traditional starter plans, not an invariable result.

Main fermentation and finishing complete different jobs

In multiple parallel fermentation, enzyme-driven sugar release overlaps with yeast fermentation. The conventional three additions expand the mash over four days, including a rest after the first addition. Temperature and time must keep the system useful as conditions change. Alcohol can reach roughly 17–20% before later adjustments without distillation.

At the chosen endpoint, liquid and solids are separated. Yabuta uses a mechanical filter-press approach; fune arranges mash-filled bags in a press; fukuro or shizuku methods collect the drip from suspended bags. Sedimentation lets fine particles settle. None of these words means that every microorganism and enzyme has been inactivated.

Eligible brewing-alcohol addition commonly occurs before pressing and can influence aroma transfer and balance. Charcoal fining adjusts selected colour and sensory components; muroka omits it in this syllabus context without implying no pressing. Pasteurisation controls relevant organisms and enzymes through bulk or in-bottle treatment. Brewery storage can be in bulk or bottle, and dilution adjusts strength. Genshu identifies omission of routine dilution, not one universal alcohol figure.

Revise eight premium names as a connected map

The NTA labeling standard gives the underlying requirements. Shared conditions include the relevant rice criteria, at least 15% kōji rice and appropriate quality. Where premium brewing alcohol is used, the limit is no more than 10% of polished-rice weight on the specified 95%-alcohol equivalent basis. It is not final bottled abv.

Numbers do not establish the complete grade. For fruity ginjō versus rich junmai style development, compare six decisions: rice type, polishing, soaking and steaming, kōji style, yeast type and fermentation management. Ginjō and junmai can overlap; neither word guarantees sweetness, body or personal preference.

Specialty styles and eight label terms

Nigori uses coarse filtering to retain fine material, causing cloudiness and affecting texture without requiring sweetness. Nama-zake is unpasteurised. Nama-chozō is stored unheated and pasteurised afterward; nama-zume is heated before storage and not given the later second treatment. NRIB’s glossary provides a useful English comparison.

Sparkling sake can receive added carbon dioxide or retain fermentation gas, including through bottle fermentation. The presence of bubbles alone cannot identify the method. Koshu is deliberately matured, typically at the brewery for at least two years in the syllabus framework, with temperature and vessel conditions influencing development. Ageing can produce attractive character but isn’t automatic improvement.

Recognize nihon-shu 日本酒, sei-shu 清酒, honjōzō 本醸造, junmai 純米, tokubetsu 特別, ginjō 吟醸, daiginjō 大吟醸 and nama-zake 生酒. Read full combinations rather than guessing from one familiar character. Broad product terms, grades and treatment descriptions answer different questions.

Storage, faults, service and pairing deserve their five questions

Keep sake chilled, upright and away from bright light, and generally enjoy it young. Sensitive styles need refrigeration as directed. Once opened, close securely and protect the remaining product. The NRIB storage guide explains why temperature, light and oxygen matter.

Distinguish oxidation, out-of-condition unpasteurised sake, light damage and microbial spoilage. Similar sensations do not prove identical causes. An intended amber koshu is not automatically faulty, and cloudiness alone doesn’t diagnose spoilage in nigori. Use intended style and available history alongside observations.

Serve very chilled, chilled, at room temperature or warm as appropriate. Hot-water bath and microwave are the prescribed warming methods, with suitable vessels and temperature control. Wine glasses, o-choko, kiki-choko and masu are drinking vessels. Tokkuri and katakuchi are serving vessels. For pairing, prioritize personal preference, flavor intensity and sweetness, then refine with other useful sensory relationships.

Optional tasting reinforces mechanisms without becoming an exam

The recommended learning comparisons include futsū-shu or honjōzō, daiginjō, rich junmai, off-dry or dry sake and sweet sake for calibration. Compare ginjō and non-ginjō polishing, kimoto or yamahai, and ideally three sakes from the same brewery using yeast 7, 9 and 1801 at similar polishing ratios. A high-alcohol genshu over 17% can illustrate strength and balance.

Specialty samples include nigori, sparkling sake, nama and koshu. Two contrasting tokubetsu examples demonstrate diversity rather than one fixed special taste. Ginjō and non-ginjō examples served chilled, warm and with food can show how service changes perception. These are optional learning exercises, not assessed tasting tasks. Readers avoiding alcohol can use technical descriptions and written comparisons instead.

Turn mistakes into a targeted return journey

Use Articles #2–5 for rice and kōji, #6–8 for water, yeast and fermentation, and #9–10 for separation and finishing. Return to #11–14 for categories and grade rules, then #15 for the integrated style explanation. Articles #16–20 cover specialty styles and labels; #21–24 cover practical storage, faults, service and food.

After marking a mock, classify each error as a missing fact, a confused mechanism or a misread question. Correct the explanation in a sentence of your own. For a polishing error, calculate a new example; for a nama error, redraw the timeline; for a grade error, check all conditions rather than one percentage. This is more useful than memorizing the position of the correct letter.

Plan the hour before starting the timer

Read each stem before looking for a familiar word in the options. A question about alcohol addition may contain a polishing figure as a distraction; a question about pasteurisation may contain a plausible filtration term. Identify the operation or requirement actually being tested, then compare the alternatives against that target.

If an answer remains uncertain, eliminate choices that contradict a known mechanism and select the best remaining option. Because the official format has no negative marking, leaving a question unanswered provides no scoring advantage. Keep enough time to check that every question has one indicated response and that the answer positions have not shifted accidentally.

After the first mock, resist immediately taking the second as a memory exercise. Return to the weak-area lessons, explain the missed mechanisms and practice a fresh calculation or timeline. Then use the second paper under the same timed conditions. Comparing the outcome results is more informative than celebrating a higher total without checking which areas still need attention.

One-page revision summary

Follow ingredient, decision, effect and style. Keep percentages attached to their proper measurement, grades attached to complete requirements and specialty words attached to their own production facts. Explain mechanisms before memorizing labels. For each mock, set 60 minutes, close the notes and answer all 50 questions with one choice each. Mark afterward using the separate explanations, total the score and outcome results, then revise the mechanism behind every uncertain answer.

Examination A answers and explanations

1. B — Yeast. Yeast ferments sugars; kōji enzymes first help make those sugars available from starch. Mapping: LO1.

2. A — Lactic acid. Direct lactic acid addition is characteristic of the standard sokujō starter approach. Mapping: LO1.

3. D — Futsū-shu. The basic category can permit these formulation additions; premium junmai branches do not. Mapping: LO1.

4. C — Miyama-nishiki. Miyama-nishiki is a rice variety; the other terms concern starter, treatment or service. Mapping: LO1.

5. B — Germ. The germ can develop into the plant, whereas the endosperm is storage tissue. Mapping: LO1.

6. A — Harvest. Harvest follows ripening; the other operations are beverage-production choices rather than field stages. Mapping: LO1.

7. D — 210 kg. The remaining weight is 300 multiplied by 0.70, giving 210 kilograms. Mapping: LO1.

8. C — Moving from 70% to 50% remaining. A lower remaining-weight ratio means more of the original rice has been removed. Mapping: LO1.

9. B — Steaming and gelatinisation. Heat and moisture change starch structure; enzymes later release sugars from it. Mapping: LO1.

10. A — Washing. Washing removes powder left by milling, while absorption can begin during the water contact. Mapping: LO1.

11. D — Controlled moisture for subsequent steaming and brewing. Soaking aims at suitable water uptake, not the maximum possible absorption. Mapping: LO1.

12. C — Starch breakdown by amylases. Amylolytic enzymes help release carbohydrates from starch, supporting yeast fermentation. Mapping: LO1.

13. B — Protein breakdown can release amino acids and peptides. Different enzymes act on proteins and starch, creating different downstream contributions. Mapping: LO1.

14. A — Mould activity generates heat within the rice. Growth creates heat, so internal material conditions can differ from the surrounding air. Mapping: LO1.

15. D — Tsuki-haze. Tsuki-haze concerns this managed growth pattern rather than a finished grade or press. Mapping: LO1.

16. C — Iron. Iron has adverse brewing effects, while other mineral components can be useful. Mapping: LO1.

17. B — 9. Number 9 is the early ginjō reference; 60 and 50 are familiar polishing figures. Mapping: LO1.

18. A — Nutrients, polishing, kōji style, temperature and yeast. The five factors interact to shape the environment and aromatic capabilities of fermentation. Mapping: LO1.

19. D — Kimoto. Kimoto uses bacteria-led acidification with the traditional rice-working step described in the course. Mapping: LO1.

20. C — Yamahai. Yamahai removes the rice-working step, not the bacteria-led source of starter acidity. Mapping: LO1.

21. B — The balance of parallel transformations. Saccharification and alcoholic fermentation overlap and must support the intended course together. Mapping: LO1.

22. A — A rest from the next addition while activity continues. The intervening rest allows development before the remaining volume increases. Mapping: LO1.

23. D — Shizuku collection. Gravity-dripped bag collection differs from forced-pressure and compositional adjustment operations. Mapping: LO1.

24. C — Charcoal fining. Muroka here concerns omission of charcoal treatment, not necessarily every form of clarification. Mapping: LO1.

25. B — Adding suitable water. Dilution distributes the alcohol through more liquid, changing concentration and balance. Mapping: LO1.

26. A — Futsū-shu. Futsū-shu is the basic category rather than one of the eight premium grades. Mapping: LO2.

27. D — Junmai. Standalone junmai has no numerical polishing ceiling, although its other requirements still apply. Mapping: LO2.

28. C — Its 70%-or-less polishing requirement. Honjōzō has a 70%-or-less condition; other requirements must also be satisfied. Mapping: LO2.

29. B — No added brewing alcohol. Junmai is an ingredient condition, not a denial of water or alcoholic fermentation. Mapping: LO2.

30. A — Daiginjō. The ratio is at or below the 50% daiginjō ceiling, but it does not prove every condition. Mapping: LO2.

31. D — At least 15% of total polished rice. The proportion describes production material rather than sediment or alcohol concentration. Mapping: LO2.

32. C — Polished-rice weight using the specified alcohol-equivalent basis. The 10% rule is a material-weight comparison, not the final sake strength. Mapping: LO2.

33. B — 59%. The polishing-based explanation requires 60% or less, with the other conditions remaining. Mapping: LO2.

34. A — Polishing is not the only possible supported basis. The standard permits an objective alternative explanation, not unrestricted use of the adjective. Mapping: LO2.

35. D — Aromatic yeast with carefully managed chilled fermentation. Aromatic capability needs suitable conditions, not a single isolated rice-polishing figure. Mapping: LO2.

36. C — Sō-haze. Its broader enzyme and nutrient contributions can support a fuller production plan. Mapping: LO2.

37. B — Coarse filtration with large openings. Nigori retains more suspended particles through the coarser separation approach. Mapping: LO2.

38. A — Check the actual product because cloudiness does not decide sweetness. The defining appearance mechanism does not impose one residual-sugar or palate profile. Mapping: LO2.

39. D — Nama-chozō. The timing of its one heat treatment distinguishes nama-chozō from the other routes. Mapping: LO2.

40. C — Bottle fermentation. Fermentation produces carbon dioxide that can remain dissolved under the closed conditions. Mapping: LO2.

41. B — Typically at least two years at the brewery, with temperature and vessel choices relevant. The specialty framework connects intentional duration with controlled storage conditions. Mapping: LO2.

42. A — 純米. 純米 conveys the junmai ingredient condition rather than special status or heat history. Mapping: LO2.

43. D — Honjōzō. The full character group identifies honjōzō, with its specific grade requirements. Mapping: LO2.

44. C — Tokubetsu — 特別. 特別 is tokubetsu; the other proposed pairs combine different prescribed terms. Mapping: LO2.

45. B — Different production facts can coexist. A grade and pasteurisation history describe separate aspects of the same sake. Mapping: LO2.

46. A — Move it to suitable refrigerated, light-protected storage. Temperature and light both require attention; one style word does not supply immunity. Mapping: LO3.

47. D — Light damage. The scenario supplies exposure evidence for light-related damage rather than a grade change. Mapping: LO3.

48. C — Wine glass, o-choko, kiki-choko and masu. These four are drinking-vessel references; tokkuri and katakuchi are service vessels. Mapping: LO3.

49. B — Mix gently and check the temperature in suitable equipment. Microwave warming can be uneven, so distribution and measurement matter before pouring. Mapping: LO3.

50. A — Flavor intensity. The finished dish’s intensity, including its sauce, should be considered against the drink. Mapping: LO3.

Examination B answers and explanations

1. C — Yeast makes ethanol; kōji supplies enzymes for breakdown. The statement confuses the starch-conversion contribution with alcoholic fermentation. Mapping: LO1.

2. B — Jōzō alcohol. Brewing alcohol is optional across sake production and excluded from junmai formulations. Mapping: LO1.

3. A — The technical non-glutinous distinction is not the everyday meaning of clinging. The syllabus non-sticky description refers to rice type, not an absolute cooked-texture promise. Mapping: LO1.

4. D — Yamada-nishiki, Gohyakuman-goku and Miyama-nishiki. These are the three prescribed sake-specific cultivars rather than methods or service terms. Mapping: LO1.

5. C — Shinpaku. Shinpaku describes the opaque white core associated with the grain’s internal starch structure. Mapping: LO1.

6. B — It can better suit extensive polishing while remaining workable. Grain properties influence practical preparation possibilities, not a compulsory finished flavor. Mapping: LO1.

7. A — 180 kg. Forty-five percent is removed; multiplying 400 by 0.45 gives 180 kilograms. Mapping: LO1.

8. D — 60%. Remaining and removed proportions total 100% on the same starting-weight basis. Mapping: LO1.

9. C — Water absorption can begin during washing. The grain’s full water-contact history influences its condition before steaming. Mapping: LO1.

10. B — No automatic quality ranking follows. Batch and continuous describe equipment organization; appropriate preparation remains the target. Mapping: LO1.

11. A — One changes hydrated starch structure; the other releases sugars enzymatically. The physical cooking step and enzyme-driven breakdown are separate transformations. Mapping: LO1.

12. D — Manage cooling and removal to stop further cultivation while retaining useful enzymes. The aim is the chosen enzyme system, not uncontrolled growth or elimination of its useful products. Mapping: LO1.

13. C — How cultivation conditions and handling are controlled. The methods manage the same mould biology through different practical systems. Mapping: LO1.

14. B — Sō-haze. Sō-haze is associated with extensive development and a broader enzyme/nutrient contribution. Mapping: LO1.

15. A — The report is incomplete for assessing all relevant water effects. Hardness is not a complete inventory of useful and undesirable components. Mapping: LO1.

16. D — 1801. Number 1801 is the specified later aromatic reference, not a polishing or material ratio. Mapping: LO1.

17. C — Reliability is a capability, not an absence of aroma or quality. The complete production plan affects expression; a dependable strain is not inherently dull. Mapping: LO1.

18. B — Adding lactic acid in sokujō. Direct acid addition supplies the desired acidity without the bacteria-led production period. Mapping: LO1.

19. A — No, it omits yamaoroshi rather than bacterial acidification. The handling omission and the source of starter acidity are different parts of the method. Mapping: LO1.

20. D — Additional steamed rice, kōji and water. The established yeast population is supported as the mash expands through staged additions. Mapping: LO1.

21. C — It avoids needing all potential sugar present at once while yeast works. Parallel sugar release and use support a manageable progression rather than an excessive initial sugar load. Mapping: LO1.

22. B — Managed alcoholic fermentation. Sake fermentation can reach high alcohol through the coordinated enzyme and yeast system. Mapping: LO1.

23. A — Fune. Fune organizes cloth bags under pressing conditions rather than hanging them solely to drip. Mapping: LO1.

24. D — Sedimentation. Settling uses gravity and time to remove suspended material from the clearer portion. Mapping: LO1.

25. C — Heat can control organisms and enzymes; clarity alone does not establish that. Physical particle removal and biological stability are separate finishing questions. Mapping: LO1.

26. B — Eight. The prescribed premium map contains eight names, not an extra grade for each specialty style. Mapping: LO2.

27. A — Junmai, junmai ginjō and junmai daiginjō. The junmai term supplies the no-added-brewing-alcohol condition within these branches. Mapping: LO2.

28. D — The ratio exceeds the 50% ceiling. The proposal misses the numerical daiginjō condition, regardless of other qualities. Mapping: LO2.

29. C — Its framework permits eligible alcohol addition, while junmai ginjō excludes it. Permission in a broad branch should not be confused with proof of an actual addition. Mapping: LO2.

30. B — Production classification does not establish universal preference. Regulated requirements provide information without replacing sensory judgment or individual taste. Mapping: LO2.

31. A — The honjōzō 70%-or-less ceiling. The special distinction does not erase the conditions of the base honjōzō grade. Mapping: LO2.

32. D — Jōzō alcohol. Junmai excludes added brewing alcohol while retaining the normal rice-based fermentation system. Mapping: LO2.

33. C — Ginjō, tokubetsu and other eligible descriptions involve additional conditions. A ratio supplies one fact rather than the entire ingredient, method and labeling history. Mapping: LO2.

34. B — Grain structure influences preparation, which influences later biological behavior. The mechanism runs through practical processing rather than a single inevitable tasting note. Mapping: LO2.

35. A — A delicate dry ginjō pattern. Fruit-like aroma and sugar sweetness are separate sensations in a coherent style. Mapping: LO2.

36. D — That can be coherent because kimoto/yamahai are not mandatory for richness. Starter is one contributor within a fuller production plan, not a universal texture rule. Mapping: LO2.

37. C — It must therefore be nigori. Muroka and nigori concern different aspects of treatment and suspended material. Mapping: LO2.

38. B — Heated before storage, not again afterward. Its one pasteurisation precedes storage, unlike nama-chozō’s later treatment. Mapping: LO2.

39. A — Whether it follows nama-chozō or nama-zume timing. Counting one treatment cannot locate it before or after the storage period. Mapping: LO2.

40. D — Gas can be introduced directly or generated and retained through fermentation. The source and retention of carbon dioxide define method differences, not visual clarity alone. Mapping: LO2.

41. C — Different temperature and composition histories can change the development path. Equal time does not erase the effects of storage conditions and the starting material. Mapping: LO2.

42. B — 日本酒. 日本酒 identifies nihon-shu rather than a premium branch or special distinction. Mapping: LO2.

43. A — 大吟醸. Daiginjō is written 大吟醸, retaining the ginjō group with an additional leading character. Mapping: LO2.

44. D — It is a product-type term and can include coarsely separated nigori. Legal product identity and observed clarity are different types of information. Mapping: LO2.

45. C — Appropriate storage and heat-treatment implications. Nama-zake indicates unpasteurised condition, which matters to handling without fixing other features. Mapping: LO2.

46. B — Seal it and return it to appropriate chilled, light-protected storage. Air exposure, temperature and light remain relevant after opening. Mapping: LO3.

47. A — Calling it faulty from color alone. Intentional koshu development provides context; deeper color does not establish a defect by itself. Mapping: LO3.

48. D — Katakuchi. Katakuchi is an open serving vessel with a lip, rather than one of the four drinking references. Mapping: LO3.

49. C — An appropriate heat-safe vessel in a hot-water bath with temperature checks. The water bath offers controlled warming without mixing bath water into the drink. Mapping: LO3.

50. B — Sweetness compatibility. The food’s sweetness can alter the perceived balance of the drink beside it. Mapping: LO3.
