I am keen to try brewing an IPA using only late hop additions. I am wondering if I still need to do a 1hr boil, or if I could reduce that time to 20mins, if that's when I'm adding my first hops? I brew using a partial mash and partial boil - I mash 5.5lbs of grains on the stove top, top up with DME, do a 3 gallon boil and then top up to 5.5 gallons in the fermenter. The only reason I can think of for still doing a 60 minute boil is to reduce DMS, but I don't think that is going to be an issue, given that I'm only partial mashing? Am I missing anything?
