Sulfate was my main question. Comps. have come back with "great malt character but need more hop presence." Wondering if yellow bitter profile would accentuate that. I only used 3 additions of hops, so maybe just "more" hops - perle at 60, sazz at 30, sazz at 15. 1 ounce each in 5 gallons. Maybe just throw in a couple more ounces of sazz right at the end? So, your bopils you just go 100% RO, no additions?
