This was a collaboration between Port and Tonya Cornett of Bend Brewing. They made this in the traditional Stein manner by dropping glowing rocks, heated by fire, directly into the wort. This creates all sorts of smoke, steam, and rolling boils because of the extreme heat of the rocks, not to mention is a bit of a time machine back to some of the earliest days of brewing.
Port's decision to use Black Granite was obviously a good one, because as Lagers go, this one isn't bad at all. Typical lack of aroma lager with a very dark amber color and fairly rich body. The lager starts off as you would expect, as though sitting in a beer garden in Munich. But as the taste develops, the Lager is heightened by what I can only imagine is the effects of the hot rocks, and the brilliance of the Port brewers.
