Belgian Beer 13 oz. A handful of locations provided the genesis and subsequent perfection of the art of beermaking. Belgium is one of them. This is the glass they developed to accompany their finest creations. Rounded on the bottom, tapered on the top, and flaring wide for the rim, the hourglass-shape provides maximum aeration while the short, extra-thick stem provides maximum support. The result is a glass engineered to provide the perfect balance between oxygenation while maintaining foam under the rim. 13-ounces is the ideal size for restaurant, brewery, and home guests to enjoy the perfect amount of what they love.
