My go-to boil length is 90min for any beer. Ensures no DMS in lighter pils-base beers, and I apply it to ales for the Maillard reactions / darker hues / sexy ruby tones / ease of adapting my Beersmith equipment profile. Such sexy, sexy ruby tones. Then there was that one beer. The one I made that was incredible but I've never been able to reproduce. I had about 50 people sample it at a family gathering and it remains the one EVERYBODY asks whether I have more of. It only recently occurred to me recently, when brewing that fabled magical wort, I actually miscalculated at the time and added far too much sparge water so had to increase the boil length to three hours to compensate. My question is - has anyone else noticed an improvement in a batch when extending the boil time? What style was it? Mine was an IPA. Every other aspect of that brew day was fairly vanilla. NB: I am very aware of the exbeeriments on this topic undertaken by Brulosophy and choose not to consider them.
