Hamm's Real Draft 15 Oz Tab Top Can

Hamm's 15 Oz San Francisco Draft

The Theo. Hamm Brewing Company produced this 15-ounce tab top can for its Real Draft line at its San Francisco, California facility. Following the company's westward expansion beyond its historic Saint Paul, Minnesota headquarters, the San Francisco plant in the Mission District served as a vital West Coast brewing and packaging center.

While standard industry packaging centered on 12-ounce containers and 16-ounce pints, the 15-ounce capacity served as an uncommon regional format distributed primarily in select western markets. The elongated proportions provided extra space for Hamm's bold graphics and specialized draft-style marketing callouts. The release was part of an industry movement where brewers highlighted packaged draft beer to capture tavern-quality presentation in off-premise retail formats.

Containers bearing the San Francisco mandatory line remain notable artifacts of California brewing history. Variations exist across production runs, showing differences in mandatory legal text placement, multi-city plant designations, and top lid stampings.
