Why can two spirits made from the same grain taste so different? What can a still, a barrel or a handful of botanicals change? This WSET Level 3 Spirits guide connects raw materials, production decisions and the styles in your glass through 50 free lessons.
Read from the beginning, look up a spirit you want to understand, or head straight to revision. You’ll find practical comparisons, original questions and worked explanations throughout. For Level 3 study, keep asking what changed, why it matters and what evidence supports your answer.

For revision, compare pot and column distillation, Cognac and Armagnac, or Tequila and mezcal. Practice describing the difference in your own words. Use the tasting and written-answer lessons before tackling the two original 50-question multiple-choice papers, two written mock papers and tasting simulation in Lesson 50.
You don’t need to buy spirits to use these lessons. If you choose to taste, follow your local laws and drink responsibly.
