I have had success doing a double batch spare in my cooler mash tun. I use the default beer smith efficiency of 72% and always get at or near the predicted OG. However, I would like to do a no spare batch, just to see how it goes, and to shave off a significant amount of time from my brew day. The beer I want to brew is a double IPA with an OG of 1.075. Does anyone have a rough idea of what I should put in for efficiency? The default BIAB efficiency is 70% but I'm seeing that it might be different for such a big beer. I should add that there is 0.75 lb of dextrose added to the wort for this recipe.
