20 brews in and I've just had my first disappointment. I was attempting to brew an all grain APA for friends and family at Christmas and used the Gammaray recipe from the Brewdog book 'Craft Beer for the People' as a starting point. The beer has been conditioning in the keg for 13 days and I just had a sample. It smells of nothing at all. Literally nothing. It tastes of not a lot. Possibly a bit of bready malt and maybe the merest hint of TCP. But almost nothing. No hops, no bitterness. It is really poor. Brew day seemed to go very well and the only thing I really changed from normal was that this was a first proper attempt at messing with the water profile. I tested my tap water for calcium and for alkalinity using the Salifert kits and used Phosphoric acid to drop the alkalinity. I used a little magnesium sulphate to boost the sulphate to chloride ratio to 3:1. I used campden tabs to remove chlorine and made all water additions to the total water volume before starting the brew. Having dry hopped with 120g in 20L, I can't believe that the aroma is of nothing at all. My brew notes are below and total volume was 20L. Does anyone have any suggestions, as I am scratching my head!? The recipe in the Brewdog book stated 45IBU but when I entered the ingredients into Brewfather and Beersmith, the IBU estimate was 17. Other people on this forum seem to have brewed this recipe with good results.
