I need to do a beta glucan rest, then a sacc rest. Trouble is I only need to do a beta glucan rest on one malt before adding the remainder of the grains for the sacc rest. A mash with different water/grain ratios is possible in Beersmith but different grain weights for different mash steps isn't. Unless somebody has some nifty trick I haven't thought of, I guess I could just calculate the first rest with the one malt only at my preferred water/grain ratio, then, as a separate grain bill, calculate the second rest with all the grains at my preferred ratio for the sacc rest. Then I'd have to subtract the first infusion from the second infusion and use that as my second step infusion but maybe use boiling water and easy does it till I get to my sacc temp. Anybody have better ideas?
