Today I racked my first AG from primary to secondary, and I tasted the hydrometer sample, and it was very good, but was a bit too bitter. My recipe was as follows:
11 lb. 2-row
1 lb. crystal
0.5 lb. roasted
1 oz. Kent Goldings @ 60 min
1 oz. Kent Goldings @ 30 min
1 oz. Fuggles @ 5 min
White Labs Irish Ale Yeast
O.G. was 1.062, and I have yet to check the FG as my hydrometer is sitting inside my other carboy so I don't have to take samples from it constantly.
Anyway, the bitterness was not quite like a hop bitterness. It wasn't overly pronounced, but it was there. Could it be tannins? I did a batch sparge: I poured in some sparge water, stirred, let it sit for an hour, and then drained (after filtering). I then poured in some strike water, stirred again, let it sit for 15 minutes, and then filtered & drained again. Is something about my process off that might cause some tannins to come through?
I'm not really that concerned about it, whatever it is, because this beer is still really green and a couple months in the bottle might mellow it out just right, but has anyone else come across anything like this?
