Has anyone here had success/failures with brewing a concentrated brew on the stovetop, then diluting it with water to full volume? I've done the math already and calculated my grains, hops, etc, but I was wondering if there's any reason this wouldn't be akin to brewing with extract and watering down. The beer is an ordinary bitter, so it's already pretty low gravity. My plan is to collect 2.75 gallons of 1.063 OG wort, boil it down to about 2 gallons with 14 grams of Magnum, then dilute this with 2.5 gallons of water to a total volume of 4.5 gallons (Leaving a bit of headspace for the S-04 to do its thing). By my math I'll end up with something about 3.4% abv and in the high 20s/low 30s for IBU.
