Volatile acidity in a wine is measured chiefly as

  • A.Acetic acid, indicating bacterial spoilage
  • B.Malic acid, indicating incomplete ripening
  • C.Tartaric acid, indicating the grape variety
  • D.Lactic acid, indicating a healthy fermentation

Answer: A

Volatile acidity is dominated by acetic acid and is therefore a direct measure of spoilage by acetic acid bacteria and, to a lesser extent, by certain yeasts. Tartaric and malic acids come from the grape and are not volatile.
