Bohemian Pilsener – All Grain

Statistics

Comments

Pretty much following the same procedure in fermentation as I detailed last year. Took a gravity reading at 16 days, nearly to the desired FG. Began a two day diacetyl rest (just in case) and will crash cool and rack to kegs in a few days (March 29, 2011).
