Which of the following white wines is classified as light-bodied?

Pinot Grigio, especially from Italy, is classified as light-bodied due to its typically fresh and crisp character, which is enhanced by its high acidity and moderate alcohol levels. This style of wine often features flavors of green apple, pear, and sometimes floral notes, making it very vibrant and refreshing on the palate.

In contrast, while Chardonnay can be made in a light-bodied style, many Australian versions tend to be more full-bodied due to oak aging and malolactic fermentation. Sauvignon Blanc can also vary in body, but the French versions (especially from regions like Sancerre) tend to have a medium body, with pronounced acidity and a range of herbal and citrus characteristics. Viognier, known for its aromatic profile, tends to be fuller-bodied, often with richer textures and flavors of stone fruits and floral notes. Therefore, Pinot Grigio stands out as the quintessential light-bodied white wine among them.
