Shiner Bock Shiner Bock has a tan, dense medium head that leaves a nice quilt down the sides of the glass as the beer is drunk. Its body is clear with a copper to amber color. The aroma is very sweet, almost sugary, without the typical maltiness normally associated with this much sweetness. 16 oz. Draft Beer: $4.50 16 oz. Happy Hour Draft Beer: $3.50 20 oz.
