Hopped Up offers a new perspective on Fred's favorite beverage. It's hand-blown from borosilicate glass with a removable silicone cap that makes a great built-in coaster. This bottle-shaped glass gives new meaning to the phrase "bottoms up!". Each Hopped Up holds 16 ounces- a full bottle of beer plus room for that heavenly white foam. The pure silicone "cap" coaster snaps on and off easily and cushions your glass for effortless imbibing.
