I recently got a 20 gallon Brewtech InfuSSion mash tun. It's bigger than I needed (so I think now...), but the 10 gallon wasn't big enough for my occasional big batch experiments where I split wort off into fermentors to test different fermentation parameters.
Anyway, I was brewing a 5 gallon batch (5.75 gallons into fermentor) of IPA as a test run last weekend, and I massively undershot my mash step temperature. I'm looking to see if anyone has had success with an equipment profile in BeerSmith 2 that works for this. I didn't do any "hot water conditioning" of the mash tun to try to warm things up because I figured that would just add more uncertainty in the calculations. But maybe that's a key step I need to do.
- 13.3 lbs of grain
- 1.5 qt/lb mash density
- 0.7 gal Lauter Tun deadspace (measured volume under false bottom)
Mash Volume: 20.00
Mash Tun Weight: 50lbs
Mash Tun Specific Heat: .12 cal/g-deg C
Mash Tun Deadspace: 0.00
The above settings told me to add 5.7 gallons of strike water at 158F to hit my 150F mash temperature, but I only hit 144F. I didn't have my full set-up going yet to allow me to circulate and heat in my Boil Kettle so it was kind of a pain for me. I need to figure out how to get much closer. I've always had great predictions for this come out of BeerSmith, but something is obviously way off and I'm not sure how to correct/adjust/fix.
