General Info

Formulated to be similar to Anchor Libery Ale, but bigger. This recipe, even though the starting gravity was predicted by Beer Tools to be around 1.061, turned out to be a bigger 1.070. If it attenuates like normal, the alcohol content will top 7.5% - near the top end for the style.

Brewed on a scorching 100° mid August. day. Let final hops steep in wort for 15 minutes prior to chilling. Could only chill the wort to 76°. Racked to primary and took gravity reading (August 12, 2007).
