OSTENTATIOUS BREWING

Herbstbock

Dunkles Bock

This bock will be slightly stronger and darker for the upcoming fall months. Herbst means Fall in German so I figured the title was fitting. I have been wanting a little more of the roasty, bready flavor in the beer after Sommerbock so I figured I would go big and make a Dunkles Bock.
