Which varietal is known for its light body and crispness?

Pinot Grigio is recognized for its light body and crispness, which are defining characteristics of the varietal. This white wine typically features refreshing acidity and is often enjoyed for its bright, clean flavors, making it an ideal choice for warm weather and seafood pairings. Its profile often includes notes of green apple, pear, and citrus, contributing to its perception of lightness on the palate.

In contrast, Cabernet Sauvignon and Shiraz are both full-bodied red wines. These varietals tend to have bolder flavors and more tannins, which give them a richer mouthfeel that is distinctively heavier than Pinot Grigio. Merlot, while often softer and more approachable than Cabernet Sauvignon, still exhibits more body than Pinot Grigio. The overall lighter style and brisk nature of Pinot Grigio set it apart as the correct answer in this context.
