I recently brewed beer in a meat non-Ben-Yomo pot. Is beer considered a davar charif rendering my beer impermissible to be consumed with dairy? Would it depend on how much hops were used? Are only sharp things (garlic, onions, etc.) davar charif, or also very bitter things (lemons, hops, etc.)?
No, beer is not a "davar charif." Hops are somewhat bitter, I suppose you could potentially argue if they're called charif, but the overall product, beer, is not that pungent. (Similarly, some out there treat mayonnaise as davar charif because one of the ingredients on the label is lemon juice! But the product mayonnaise is not sharp-tasting! My father asked R' Shimon Eider zt"l about this, who concurred that mayo is absolutely not a davar charif.
