A varietal is defined as wine that is labeled with the predominant grape, minimum 75%, used to produce the wine. Which statement best describes this concept?

• A. The study of winemaking
• B. The wine that is labeled with the predominant grape, minimum 75%, used to produce the wine. I.e Merlot
• C. The year the grapes are harvested
• D. A natural compound from the grape skins

Answer: (B)

A varietal wine is identified by the grape variety that makes up the majority of the wine, typically at least 75%. This means that if Merlot accounts for 75% or more of the blend, the bottle is labeled as Merlot, reflecting the grape that defines most of its character. The remaining up to 25% can be other grape varieties, but they don’t have to match the label. This labeling helps consumers anticipate the wine’s typical flavors and style associated with that grape.

The other statements refer to different concepts: the study of winemaking is oenology, the year the grapes are harvested is the vintage, and a natural compound from grape skins would be something like tannins or anthocyanins, not a labeling rule.
