This beer should be bitter and have a nice “Spalty” nose to it. But to keep the hops from overwhelming the palate the malt has to come through as well. The roasty undertones of the Munich and Vienna malts complement the aggressiveness of the hops very well.

Step by Step
Mash at 153–154 °F (67–68 °C) for 30 minutes. Boil for 60 minutes. Ferment at 58–60 °F (14–16 °C) for 5 days. Allow temperature to rise naturally (but not above 68 °F/20 °C) until day 7 or 8. Then crash to below 40 °F (4 °C) over 4 days, rack off yeast and lager for 20–30 days to below 34–38 °F (1–3 °C) if possible.
