? about adjusting a recipe for lower ABV
I'm interested in making some of my favorite recipes more "sessionable" and was wondering how this might be best accomplished.
Would you suggest simply scaling all the grist down (maintaining the same percentages) to get a lower OG?
Or, is it best to only reduce the base malt and maintain all of the specialty malts at the same weights as the original recipe? The volume being brewed is not changing, so I'm thinking this may be the way to go.
I'd like to keep them just as flavorful, only not quite as strong.
I'd think you would keep the specialty grains close to the same and lower your base grains. You might also want to lower your IBUs accordingly to keep a similar IBU:GU ratio.
That's just my guess. I'm anxious to see what somebody with more experience has to say.:mug:
good point - maintaining the IBU:SG ratio. thanks, had overlooked that...
I would lower everything, specialty grains, base grain, and hops to keep the wort fermentability, color, and bitterness the same.
Do you have an example recipe you are looking to drop sessionize?
Sure, an example would be this Alesmith IPA clone below (found it at brew365.com). It's a 1075 beer and I would probably like to drop it down to the 1055-1060 range, which should lower the abv by ~2-2.75%.

Cool and ferment at 65° to 68°
You have so few specialty grains, I'd just leave them as-is. If they were 10-15% of the bill, I'd scale them back. My Bent Rod Rye is a 2/3rds clone of Hop Rod Rye and almost 1/3 of the bill is specialty grains, so they got scaled.
I would probably only drop the FWH and 60 minute additions... I would be inclined to leave the 15 minute and under hopbill intact.
Cool, thanks for all the insight!
