My 1st Brew (nut brown ale) went great. My 2nd brew (pilsner) not so much... I use the true brew kits. 2 weeks in the fermenter, specific Gravity dropped to 1.020 from an initial of about 1.040. Decided to let it sit another week. Now at 3 weeks in the fermenter, its still at 1.020. Do i bottle and hope for the best or toss it and start over? Any help would be appreciated.
