This question has kept me up at night and the rabbit hole only goes deeper. No-boil dme is fine, but you're not getting the full potential of flavor and bitterness from your hops. Alpha acids isomerize in temps above 175. No boil = no isomerization. How about boiling hops in water? No...just no. Too much bitterness and it'll feel like you just ate a dandelion. Boiling is good, but you risk scorching the extract. What about a late extract addition? This is fine and great because less scorching and lighter beer, but you can end up with an overly bitter beer. What about limiting the amount of hops in a late extract addition? Now we're talking, but what about the flavor and aroma hops? Maybe limit those too, but less than that of the bittering hops. Screw it - how about just a full volume boil? That way the extract is diluted enough so it won't scorch and there's enough sugars for appropriate hop utilization. Sounds great... let's talk about the Milliard reaction now ... [jumps out closest window]
