Newbie screwup.
I forgot to crush my extract grains which account for about 9% of grain bill.
Does anyone have a clue as to how much it effects the efficiency? Should I assume I got 40% or 20% of the sugars or even less? I still have the opportunity to add some dry malt as I’ll be starting my boil soon.
Yes ^^^ relax, you have plenty of time to add the extract if you want to get closer to your intended gravity. Mash extract efficiency estimates are based on 100% conversion , you will max out at just over 91% conversion. So multiply your expected efficiency by .91- ie .91 * .8=72.8% efficiency. But it depends on those speciality grains as they are lower in sugars and can very a lot by type as Denny has alluded.
I think you guys are right on. The water I used for extraction did color up. I added
some extra dry malt extract and my OG finished at 1.062, a fraction higher than I had intended.
I’ll keep my fingers crossed until it’s fermented, bottle-conditioned and chilled.
