The Dogfish Head signature glass is the perfect vessel for imbibing our brews. It is subtly decorated withour logo front and center. The coolest feature, however, is a tiny DFH logo that has been laser-etched on the bottom of the inside of the glass– known as nucleation, it is a roughened etch that creates a gorgeous tiny stream of bubbles in your beer. When full to the brim, this glass holds 16 oz. Hand wash in warm water and dry– no dishwashy. **Please note– these are blown glass, not pressed. They have tiny bubbles, slight imperfections, and wee little marks. These are a natural part of blown glass. **Oh, and just to be sure you got it– again, keep ‘em out of the dishwashing contraption.
