So I am making the jump from extract to all-grain and was targeting a 20 gallon mash tun. I still want to stay with 5 gallon batches, but I love big stouts and want to have a mash tun that can hold a large grain bill (28-30lbs). Plus if i ever do want to increase my batches to 10 gallons it won't be a problem.
My only problem now is that the manufacturer (Ssbrewtech) says it doesn't recommend the 20 gallon mash tun for 5 gallon batches. What do you guys think? Obviously i will be ok with the high gravity stouts, but will I have trouble mashing a 5 gallon pale ale in the 20 gallon mash tun?
Thanks for your help.
