June 20th, actively brewing a Clone for Heineken's, basically a Pilsner Lager. Low efficiency is my problem, corrected it by adding 3 lbs. light dry malt. But why did it happen? I normally get 75 - 80 efficiency. Without the additive malt I hit a blazing 40% . I use beersmith to get and build my recipes and check my numbers. My pre boil numbers should have been at adjusted to 1.048 for this Pilsner, but before adding malt the pre-boil numbers were 1.021. After adding the malt it hit 1.041 and I started the boil, which will be 90 min boil, this is a 5 gal batch. The following is my general info on this brew. Anyone know what happened?
