In a previous blog post, we shared our anecdotal experience with excessive sulfate levels in beer, particularly in hop forward styles like IPA's. You view the article here, but in summary, we found that a number of our beers, all of which featured loads of hops added late in the boil and at dry hop, were completely lacking in hop aroma and flavour. On top of this, they had a harsh, astringent bitterness that overpowered everything else, and a strong malty sweetness. In short, these beers just weren't any good, and we ended up dumping a couple of them.
