Which of the following is a red wine known for high acidity?

The selected answer is Chianti, which is indeed a red wine recognized for its high acidity. Chianti, primarily made from the Sangiovese grape, typically exhibits bright acidity, contributing to its refreshing character and making it an excellent companion for food. High acidity in wine is a crucial factor as it enhances the wine’s balance and structure, especially in fruity and tannic wines, which is a hallmark of Chianti.

Other red wines listed here, although they may have varying levels of acidity, do not showcase the same pronounced acidity commonly found in Chianti. For instance, Merlot is generally known for its smooth, soft texture and less acidity. Shiraz often has a richer, bolder profile, focusing on fruit and sometimes spice, which can result in lower perceived acidity. Zinfandel varies widely depending on the ripeness of the grapes and winemaking style, but typically it is fruit-forward and may have medium acidity, which does not place it in the same high-acidity category as Chianti.
