Have been brewing 5 gallon batches with a 10g Boilermaker for about 18 months. Buddy and I are moving up to 10g batches so we picked up a 20g kettle.
Last weekend we did two 5g batches, one using the 20g kettle to boil. Holy crap do you ever boil a lot more off with the bigger surface area!
Has anyone else found this? My normal evap rates in Beersmith are 15%. What should I adjust this to? Or will our larger batches "self-adjust" so we are starting with (say) 15 gallons pre-boil to get 10 in the keg (5g boiled off, lost to trub, shrinkage (no Seinfeld jokes please), etc) instead of 7.5 gallons to get 5 in the keg?
I'm pretty sure I'm overthinking this. Maybe it will just take a bit of experimentation.
