Let's talk 30 minute boil ... using hop extract, the need to boil for bittering is gone.

I've done 20 min. boils.  You just increase your bittering hops by 50%.

whats your boil off % for those 20 minute boils?

Don't recall without checking, but not much as you'd expect.  Particularly since I was doing it indoors on an induction plate.

I averaged 15-20% outdoors on 60m and 30m I get half that.  WRT comparing 30m vs 60m IBU, there is surprisingly little difference.  Honestly, I think we're talking like 10-20% change.  No need to resort to use ISO oil.  WRT DMS; Our boiloff rates are HUGE compared to pros.  They average 4% over 90m.  That's the reason they boil so long, they HAVE to.

Details please. What size batch? How long did it take to get to get to a boil? How did it compare to boiling outdoors with propane?

2 gal., 1800W plate.  Started with maybe 2.5 gal. (I'd have top check my notes to be sure).  Maybe 20 min. to get to boil...don't recall exactly.  Best I could get was a low rolling boil, but that was enough.

Perhaps because the genesis of brewing back in Mesapotamia was changing. Contaminated water into a safe tasty beverage through boiling
