Wine glass design is far from arbitrary. The wide bowl allows us to swirl the wine and observe its color and layers, while the tapered rim concentrates aromas. Different red wines pair with different glass shapes: Burgundy glasses have wider bowls perfect for delicate Pinot Noir, while Bordeaux glasses are taller and ideal for tannic wines like Cabernet Sauvignon. The right glass helps each wine express its unique characteristics to the fullest.
