And lastly, my 96 quart mash tun profile for 11 gallon batches.īy the way, I use the 96 quart profile for an 11 gallon batch for the big beer and I use the 96 quart mash tun profile for the 5.5 gallon parti-gyle batch. My 96 quart mash tun profile for 5.5 gallon batches. My 48 quart mash tun profile for 5.5 gallon batches. I'm attaching the three equipment profiles that I use. I've found this to work very well for me. Having the 96 quart equipment profile allows you to use the 2/3rds - 1/3rds parti-gyle calculator and be fairly accurate. I have a special equipment profile for a 96 quart mash tun. I keep repeating until I have my preboil volume for my 10 gallon batch. I drain the top mash tun into the bottom mash tun again, stir well and shut the lid. I add the second sparge water to the top mash tun, stir well and shut the lid. I then drain the top mash tun into the bottom mash tun, stir well and shut the lid. I add the first sparge water to the top mash tun, stir well and shut the lid. I then lauter and drain the bottom mash tun. Once mash is complete in both mash tuns, I bring them both up to 170F. I mash like I'm doing to different identical beers. When I do 10 gallons of a huge beer, I designate one the top mash tun and the other the bottom mash tun. Your big brew set up is exactly the same as my personal set up. Maybe that makes sense, but I can't figure it out.Īny thoughts on how to calculate this? I'm OK with "close enough," as this is sort of fly-by-night operation. My thinking is that we'll end up with a higher OG using the two mashes in this fashion than if we had done a single mash 10 gallon batch this is what I'm trying to approximate with the parti-gyle calculator, but it's giving me a lower OG, preboil and postboil, than if I were to do a single mash. I'm trying to use the Braukaiser parti-gyle calculator, but it's not really designed to take the approach we're taking. It's not really a 5 gallon batch, and not really a 10 gallon batch, because of the two mashes. I'm really not sure how to calculate this, though. From there, I'm thinking I'll add another couple pounds of base malt to each tun and do a second, short mash, followed by a drain and second batch sparge infusion to get the second 5 gallon batch. What I'm thinking of doing is a first batch sparge infusion of about 4 gallons in each tun we won't use all of that in the first big beer, but simply drain both at equal rate until we hit our preboil volume. I need about 12.8 gallons preboil for my boil rig, so we'll need another 5.2 gallons total in the second runnings (or 2.6 gallons from each). We'll do an initial drain from each should give us 3.8 gallons each, or 7.6 gallons together. We both have 48-quart cooler style mash tuns, so the plan is to do exactly the same mash in each setup. We want to do 10 gallons of this beer, and since it starts at 1.100, we're of the mind that there should be plenty left to do a 5 gallon batch of something smaller (dry stout or whatever). For Big Brew this weekend, another brewer and I are taking on the official Imperial Stout recipe proffered by the AHA, with some minor modifications.
