If you’re studying for your WSET Level 1 Award in Wines, understanding how wine is made is one of the most foundational topics on the exam. From grape harvesting to fermentation to the differences between red, white, and rosé production, this section rewards anyone who takes the time to understand the mechanics behind every bottle they open.

Jesse spent years making wine in Burgundy, Oregon, California, and Portugal’s Douro Valley before we started Wine Scribes — and that hands-on winemaking background shapes how we teach this stuff. We don’t just ask you to memorize steps; we try to give you the “why” behind each one, so the knowledge actually sticks.

This free quiz covers the key winemaking concepts tested at WSET Level 1: fermentation basics, the role of yeast, how red and white wines differ in production, and the basics of sparkling and fortified wine styles. Take it as many times as you want — repetition is genuinely the best way to lock in this material before your exam.

What is fermentation in winemaking? Crushing grapes to extract juice The process of aging wine in barrels The conversion of grape sugars into alcohol and CO2 by yeast Blending different grape varieties together

Why does red wine typically have more tannin than white wine? Red grapes contain more tannin in their flesh Red wine is fermented with the skins, which contain tannin — white wine has little or no skin contact Tannin is added to red wine during production Red wine is fermented at higher temperatures that extract tannin

How is rosé wine most commonly made? By mixing red and white wine together By allowing brief skin contact with red grape skins, then removing them before full color extraction By using naturally pink-fleshed grapes By removing color from red wine through filtration

What does "dry wine" mean? Wine served without ice Wine stored in dry conditions Wine where virtually all grape sugar has been converted to alcohol Wine with no fruit flavors

What does tannin contribute to red wine? Sweetness and body A drying, gripping sensation and structure that helps wine age Acidity and freshness Alcohol and warmth

Where does wine get its color? From the grape flesh From approved color additives From the grape skins — color compounds are found only in red/black grape skins From the oak barrels

Why is acidity important in wine? High acidity makes wine taste sweet Acidity prevents the wine from aging Acidity provides freshness, structure, and food-friendliness, and helps wine age gracefully Acidity adds body and richness

What is the main purpose of oak barrel aging? To filter impurities before bottling To increase the wine's alcohol content To add flavors (vanilla, spice, toast) and allow slow oxygen exposure that softens the wine To keep the wine cold during storage

What does the vintage year on a wine label indicate? How long the wine has been aged in barrel The year in which the grapes were harvested The year the winery was founded The year the wine should be consumed by

What does "body" in wine refer to? The color and appearance of the wine The amount of tannin in the wine The weight and fullness of wine on the palate — from light to full-bodied The total volume of wine in the bottle

How do sparkling wines get their bubbles? Bubbles are injected mechanically, like carbonated soda The grapes naturally produce CO2 A secondary fermentation traps CO2 — in bottle (traditional method) or in tank (Charmat method) Bubbles form naturally when the wine is poured cold

What is a fortified wine? Wine with added vitamins and minerals Wine with grape spirit added, raising alcohol to 15–22% ABV Wine aged in a temperature-controlled facility Wine that has been certified organic

What is residual sugar in wine? The natural sugar present in fresh grapes The sugar remaining in the wine after fermentation is complete Sugar added by the winemaker after fermentation The sweet sensation from glycerol

What does decanting wine accomplish? It rapidly cools the wine before serving Pouring wine into a wide vessel exposes it to oxygen, or separates it from sediment It adds sulfur to preserve the wine It tests for cork taint

What are "lees" and why might a winemaker keep wine on them? Grape seeds removed during pressing The wooden staves of the barrel Dead yeast cells that settle after fermentation; contact adds texture, richness, and complexity Tartrate crystals that form during cold stabilization

What does "maceration" mean in red winemaking? Crushing grapes before pressing Aging wine in new oak barrels Soaking grape skins in contact with juice/wine to extract color, tannin, and flavor Adding water to dilute over-concentrated wine

What does blending mean in winemaking? Mixing wine with water to lower alcohol Combining wines from different grape varieties, vineyards, or vintages to achieve a desired profile The process of filtering wine before bottling Adding yeast and sugar to trigger secondary fermentation

Why do winemakers harvest at different times? Labor availability determines picking date Regulations require different varieties to be harvested separately Different varieties ripen at different times, and timing affects sugar, acid, and flavor Grapes must always be harvested before October in the Northern Hemisphere

What is the difference between still wine and sparkling wine? Still wine is always aged; sparkling is always young Still wine has no significant carbonation; sparkling contains dissolved CO2 Still wine is dry; sparkling is always sweet Still wine is always from Europe; sparkling from the New World

What does ABV (alcohol by volume) tell you about a wine? The quality level of the wine The percentage of the wine that is pure alcohol How much added sugar the wine contains Whether it was naturally or artificially fermented

Study Tips for WSET Level 1: How Wine Is Made

The production section of WSET Level 1 is surprisingly logical once you understand a few core concepts. Here’s how we’d approach it:

Start with fermentation. Everything in winemaking flows from one central reaction: yeast converting sugar into alcohol and CO₂. If you understand why fermentation happens and what stops it, you’ll be able to reason through most production questions rather than just guessing.

Learn the red vs. white production split first. The key distinction is skin contact — red wines ferment with their skins (which gives color, tannin, and body), while white wines are typically pressed and fermented without skins. Once that’s clear, rosé becomes easy to understand too.

Fortified wines often trip people up. Remember: fortification means adding grape spirit to stop fermentation early (leaving residual sugar) or after fermentation (producing a dry style). Knowing when the spirit is added determines whether the wine is sweet or dry — that’s a classic exam question.
