found another beer, seemingly new to San Antonio markets.
Kulmbacher Eisbock

"Eisbock is a traditional Kulmbach specialty beer that is made by freeze distilling a doppelbock and removing the ice to concentrate the flavor and alcohol content. Alcohol content ranges from 9% to 40% by volume. It is deep copper to dark brown in color, often with ruby highlights. Head retention is frequently impaired by the higher alcohol content. It has a rich, sweet malty flavor, balanced by a significant alcohol presence. It has a clean, lager character with no hop flavor"
