    1st batch on new 3bbl system, scaling question for ya!

    About to brew the 1st batch on our 3bbl system and am a bit concerned about the scaling up from my 5 gal recipe. My tun is 150 gallons and, using beersmith to scale up, it tells me that it will take 220 lbs of grain? Seems like a lot to go in a 150 gal? With 220 lbs in there would anyone out there be able to give me a quick estimate as to how much water would fit with the grain? Thanks

    Not sure if this helps, but i think I can usually fit about 125 lbs of grain and about 37 gallons of water in my 55 gal. Mash tun, it's way at the top, but fits.

    We brew on a 3 barrel system, psychobrew 2 mash tuns, 2 boil kettles, and for our IPA we use about 105 lbs of grain at 85% efficiency for a 1.064 SG IPA. If we want to do high gravity beers we run both mash tuns off into 1 boil kettle and then empty the mash tuns and start all over again. Doing this we got 3 bbls of 12.7% abv Russian Imperial Stout.

    https://www.rackers.org/calcs.shtml might help with how much you can mash at once.

    105 lbs for 3bbl? That seems like a low number? Are my scaling numbers way off? Other recipes I've seen for 3bbl are also in the 180-230 lb range,,, hmmm I know we can experiment it's just an expensive trial if we mess up! Ha

    I brew on a 7 bbl. system and most of my recipes are between 370 - 550 lbs of grain, with an extraction efficiency of between 85-90 using promash. The lower the amout of grain the better the effciency.

    Ahhh yes, we brew on a split system. 2 mash tuns, 2 boil kettles therefore double my amounts and we are about at 210 lbs of grain. Sorry for the confusion.. I was looking at the recipe for a 1.5 bbl batch and forgot to double it
