Just brewed Palmer's Oak Butt Brown ale 7lbs pale ale 2lbs amber malt .5 lb caramunich III .25 lb chocolate malt 14g nugget at 60 14g fuggles at 15 Calculated IBU = 29 OG=1,054 Tasted my wort now, and tastes quite bitter. I mashed at the recommended 152F I noticed beforehand that the amber malt has quite a bitter taste to it. The amber malt was milled about 3 months ago, all other malts where milled yesterday. Could the amber malt have gone bad? Will this bitterness mellow out during the course of fermentation? I was really looking forward to this brown ale.
