Vienna Lager – All Grain

Statistics

Comments

Temperature probe escaped my freezer, causing it to kick it on for a full 24 hours - thereby freezing solid both kegs of this beer. Thawed them out and redistributed the liquids. Will it have any affect on flavor? Not sure yet. Although the taste I did have before I redistributed the liquid was very much like a doppelbock (October 14, 2011).
