A can of Component’s Doppelback next to a glass of it. Milwaukee’s Component is now distributing in Madison. It’s the height of bock season. A doppelbock from Milwaukee’s Component Brewing Company, a newcomer to the Madison market, just hit local stores.It’s medium- to full-bodied with smooth bready caramel sweetness. Component has a different take on the style: a touch of rye malt gives light spicy dryness to the finish. This is a fairly strong, warm doppelbock at 8% ABV and is available in four-packs of 16-ounce cans ($18).
