The glasses in this set of four were specifically shaped to highlight the fruit in full-bodied red wines with high acidity and moderate tannin, such as Barbaresco, Barolo, Barbera, Red Burgundy, Gamay, Nebbiolo, and Pinot Noir. The mouth of the Pinot Noir glasses draws wine to the areas of the tongue that perceive sweetness, highlighting the fruit and mellowing the acidity. The large bowl provides room for the wine's rich bouquet to unfold. Each glass stands 8-1/4 inches high and holds 24-3/4 ounces of wine.
