So I just brewed my first all grain batch last night, a hop bursted rye ipa. After realizing my 5g kettle wouldn't hold the 7 gallons of wort coming out of the mashtun I split it between that and my other 5 gallon pot, no problem. Boil went fine, along with the 30 mins of 5min 2oz hop additions(my first time using whole leaf hops). Cooled both in an ice bath in record time, for me at least. Then pour it all into my fermentor. What was supposed to be an ~6gallon batch, only 4 gallons made it to the fermentor. I had no idea the whole leaf hops would take up that much wort. I wouldn't think 2 whole gallons. But lesson learned on those hops, and now I know. And knowing is half the battle right?
