Distinguish primary, secondary, and tertiary aromas; provide examples and origins.

• A. Primary aromas are grape-derived (apple, citrus, floral); secondary arise from fermentation (esters, bread); tertiary develop with age (nutty, leather, mushroom).
• B. Primary aromas develop with age.
• C. Secondary aromas are only from aging.
• D. Tertiary aromas are from fermentation.

Answer: (C)

The central idea is that wine aromas fall into three origins: from the grape itself (primary), from the winemaking process (secondary), and from bottle aging (tertiary). Primary aromas come from the variety and its ripening—think apple or citrus and floral notes that reflect the grape’s own compounds. Secondary aromas arise during fermentation and winemaking, so they come from processes like alcoholic fermentation forming esters (fruity scents) and autolysis/lees contact giving bread/yeast notes; malolactic fermentation can add buttery notes, and oak aging can add vanilla or spice. Tertiary aromas develop with time in the bottle through oxidation and maturation, producing nutty, leather, mushroom, or toasty components.

So the complete framework is primary from the grape, secondary from fermentation and winemaking, and tertiary from aging. The idea that secondary aromas are only from aging is not correct because fermentation itself generates many secondary aromas, while aging contributes to tertiary characteristics.
