The only variable there would be the mash efficiency. That should be pretty close to the pre-boil gravity. You could try plugging the pre-boil water volume into you calculator as the final volume (or batch size), then see what it says the FG should be. I'm not sure what your pre-boil og should be, but you can just take a hydrometer reading after mashing, before boiling (remember to adjust for temp). I would mash with about 3.2 gal and sparge with about 4.4gal. Also your water measurements seem off (unless I'm missing something). I really don't have much experience with BIAB, but I would say figure about. How could I compensate for it being higher than expected (other than using AlC's infamous MOAR HOPS)?Īnd what seems to be the most common outcome for BIAB - slightly higher or slightly lower efficiency?
How do I know what my pre-boil OG should be? I don't have any kettle dead space (no valve). Modified 'sparge' with 3 gallons (depending on future, better boil-off prediction) Mash 4.75 gallons at 153 for 60 min (expecting to lose ~1.25 gal to absorption - is this way off?) I just don't want this to be underhopped - so I turn to you all, who are incredibly helpful.įor 5 gallons, here's what I'm thinking (calculations by Brewtoad):ĥ oz Simcoe (nevermind the schedule). Ideally it would finish around 5.5% or so.
I'm doing a two-row/Simcoe smash, shooting for a pitching OG of around 1.053.
#Mash tun dead space kettle update
I don't have any boil-off estimates yet, but will update this thread next week after I move and put together a system of sorts and test a boil-off rate. I'd heard that efficiency with BIAB can suffer, but then doing some research, it seems like it can be as high as 85%. I'm making the step to all-grain, starting with BIAB.
