Eclavin WSET Level 2 - Episode 16
Real-World Exam Episode
In the production of a standard white wine, which combination of pre-fermentation stage and fermentation temperature is typically used to maximise the preservation of fresh 'Primary Aromas'?
- A. Pressing before fermentation – Fermentation at cool temperatures (12–22°C).
- B. Maceration (skin contact) before fermentation – Fermentation at warm temperatures (20–30°C).
- C. Pressing after fermentation – Fermentation at ambient room temperature.
- D. Fermentation after heating the oak barrels – Cold stabilization during fermentation.
Critical Answer & Explanation
Answer: A. Pressing before fermentation – Fermentation at cool temperatures (12–22°C). Explanation: Because white wines do not require the extraction of tannin or deep colour from the skins, the grapes are typically pressed before fermentation begins to separate the clear juice from the solids. Subsequently, to protect the delicate floral and fruity characteristics (Primary Aromas) inherent to the grape variety, fermentation is conducted at cool temperatures (12–22°C), usually in temperature-controlled stainless steel tanks.

Expert Mastery Theory
White winemaking is an exercise in 'Purity' and 'Freshness': 1. Pressing First: Immediate removal of skins and seeds prevents the extraction of unwanted bitterness and colour. 2. Cool Fermentation: Lower temperatures slow down the yeast's activity, ensuring that volatile aromatic compounds (like citrus, green fruit, and floral notes) do not dissipate. 3. Inert Vessels: The use of stainless steel tanks or concrete vats (Inert Vessels) helps shield the wine from oxygen, maintaining the grape's natural vibrancy. 4. Clarification: Before fermentation, the juice is often chilled to allow any remaining solids to settle, ensuring a cleaner fermentation and a more precise final style.
Pass-Guarantee Tip
[Trap]: Do not assume that "White wines are fermented with their skins like red wines." Skin contact is generally avoided as it adds tannin and gold/orange hues (with the exception of specialized 'Orange' or 'Amber' wine styles). [Tip]: In the L2 exam, if you see the words 'White Wine' or 'Aroma Preservation', immediately link them to 'Pressing Before Fermentation' and 'Cool Temperature.' Coolness is the pride and protection of white wine.
