Im thinking what might differentiate HB from pro breweries is maybe time that it takes from mash to boil. It takes me 20 min or so to reach boil maybe in the big brew houses this may take twice as long?? In that above article the dms formation in 80- boiling wort is an important factor and the cooling down phase if i understand it correctly so maybe this is where we can be a little more flexible in boil times too.
