Hey all I brew 10 gal batches and collect 14 gal of wort to get to
11 gals in the fermenter that's after evaporation equipt losses. To what
Advantages if you boil longer is this supposed to give u a better original
Gravity as it is boiling off water I generally evaporate 1-1/2 gal per
1 hr boil
if your efficiency is off and you don't mind losing out on volume you can boil longer to increase your gravity. The other effects are that it will increase hop utilization, thus increasing bitterness, and it will increase Color. Very long boils can create some Maillard reactions that will change the flavor profile as well.
