Eclavin WSET Level 2 - Episode 63
Real-World Exam Episode
Which of the following still types is used in 'Continuous Distillation' to produce large volumes of spirits with very high alcohol levels (approx. 96%) and a 'Neutral' flavor profile?
- A. Pot Still
- B. Column Still (or Coffey Still)
- C. Solar Still
- D. Instantly changes any spirit into a shot of soju.
Critical Answer & Explanation
Answer: B. Column Still (or Coffey Still) Explanation: Distillation is the alchemy of concentrating pure alcohol by using the difference in boiling points between alcohol (78°C) and water (100°C). The Pot Still leaves the identity of the base ingredients (malt, grapes, etc.) intact, creating full-bodied, flavorful spirits (Single Malt, Cognac). Conversely, the Column Still distills continuously to remove almost all impurities, making it ideal for creating high-purity neutral spirits used for Vodka or as a base for Gin.

Expert Mastery Theory
A summary of distillation methods: 1. Pot Still (Batch): A copper, bulbous vessel. Produced one batch at a time. ABV is lower, and congeners (flavor compounds) are rich. (Flavorful, Heavy). 2. Column Still (Continuous): A giant tower structure. Can operate 24/7, producing nearly 96% pure alcohol. (Neutral, Light). 3. Heads, Hearts, Tails: In distillation, the first (Heads) and last (Tails) parts containing toxic or unpleasant compounds are discarded, keeping only the cleanest middle (Hearts). 4. Maturation: Spirits are colorless (Clear) immediately after distillation. They turn golden or brown and gain vanilla, spice, and butterscotch notes through oak aging.
Pass-Guarantee Tip
[Trap]: Do not assume that Column Stills always produce 'lower quality' spirits compared to Pot Stills. This is not about quality, but about style—choosing between 'Neutral' (Vodka) and 'Flavorful' (Whisky). [Tip]: In the exam, link 'Highly rectified/Neutral' with Column stills and 'Traditional/Batch/Flavorful' with Pot stills.
