I mash the majority of my lighter beers somewhere between 5.3 and 5.4 depending on style unless I am doing something dark. I am brewing a summer/wheat’ish’ type beer that I want to be crisp and refreshing. I went toward 5.2 once using acidulated malt and the finished beer had that lactic tang to it that took away from the character. I have been fearful of going that low since but assume it was an isolated incident and it is the only time I have used acidulated malt.
Right now I am planning to use the yellow balanced profile with an estimated mash pH of 5.3 via lactic acid. Should I use yellow bitter? Should I go lower with the mash pH? IBUs are calculated for the low 20s with the majority coming from late boil additions. The color is a bit darker at ~5.5 SRM.
I lately have been using yellow balanced for most light ales/lagers (especially) and shooting for 5.4 mash pH. The beers have been coming out great - dry, crisp, with noticeable body and mouthfeel. In the past, when I have used yellow bitter I feel that sometimes the sulfate gets in the way of the malt a bit. Just my 2 cents.
+1. I’ve backed off on the sulfate in my beers, too - even on APAs and AIPAs. I like yellow balanced for light lagers and ales, too. I’ve mashed pale beers 5.25 - 5.4 and liked the results. But I mash saisons @ 5.2 to accentuate the tart character of (most) saison yeasts.
So is FG more important than the water in creating a ‘crisp’ beer? I think I may just stick with yellow balanced, 5.3 mash pH but mash at 148f for 75 min to promote higher attenuation.
A crisp finish in a lager is definitely helped by getting good attenuation. But pH is a big factor too IMO. Beers in the 5.25-5.35 range seem to be more crisp to me as well.
Yeah hoping to get below 1.010 with K97. I think that the lower and longer mash with the addition a bit of agave at the end of the boil will help. Session went well. Appears that I hit my estimates dead on. Cooling now.
