![]() It's manageable, and certainly many have seen a great amount of success with it, so it was certainly an option. For those who need a primer, "No Sparge" is a process whereby the full volume of brewing water is added in a single charge to the grains, and lautering simply fills the kettle with no mash-out or subsequent washing/sparging additions of water. ![]() Since I could no longer heat and hold sparge water while lautering, owing to my change of circumstances, I investigated some no-sparge options. Life must go on, and seeing those beautiful, delicious Dallas Cowboy tears while I brew is totally worth it. Au revoir, dedicated sparge water heater. One of them was that, due to space restrictions, one of my two kettles and induction elements had to go (for more on induction brewing and why it might be better than whatever your doing, see my previously published work on the subject in BYO). None of them were bad enough to outweigh the joy of brewing while watching Tony Romo cry after botching a hold for a field goal in the playoffs (remember that game? Every Eagles fan has it enshrined in their "happy memories" brain file), but sacrifices they were, nevertheless. I assume different grains will absorb different amounts? The beer I’m brewing tomorrow has 50% flaked wheat!! No idea kind of absorption I’ll have with that makeup, but we’ll see.Moving from the garage to the indoor brewery entailed some sacrifices. But I definitely plan on looking at these numbers again to see what I come up with. ![]() I BIAB and let the grain sack sit in a strainer over the pot (mash tun) for about 10min and drain. I just started figuring out these numbers for my system (boil off, absorption, etc), but this is what I got from the batch I brewed last week. That’s about what I experienced during my first all grain last weekend. Is it based on past experience? Most of what I’ve read suggests 1.0 - 1.25 gallons of water absorbed per 10 lbs of grain. 75 gal lost to absorption sounds low to me. If you’re off a 1/2 gallon somewhere–it will be fine and you can make an adjustment next time.ĥgal batchġ.5qrt/lb for mash = 15qrts (or 3.75gal) of water for mash It’s the same as with all of this stuff, I don’t worry if it’s not perfect. 1) + (1 gal boil-off) = 3.7įor no-sparge BIAB, just start with 6.5 gallons (which includes boil-off) and add the amount of water that will be absorbed by the grain. Sparge volume – Calculate by adding the absorption, boil-off, and difference between your batch size (5.5) and mash water volume. 1 gal per pound.īoil-off – This differs per elevation…it’s around 1 gal per hour on a stovetop but will be more on a turkey burner (depending on how hard you boil). Mash volume – Multiply the total grain bill by the quart volume (typically 1.25).Ībsorption – Account for absorption at the rate of. It’s a little more complicated for two pots vs no sparge biab. This is what I used to do for calculations (before BeerSmith). You’ll sparge and combine and at some point because you need to get your preboil volume correct. I don’t think it matters when you add the top off water honestly. How much is too much when you batch sparge? ![]() How many of you add top up water to the boil kettle instead of just adding more water to the sparge?
