I am not sure if I am talking about the same thing or not, but I have definitely tasted beers labeled as imperial or double IPA that tasted sweet with what seemed like a table sugar flavor. I have also tasted well made imperial IPAs (like Pliny) that don’t have that table sugar flavor.
I know i’m a little late to this discussion. But I’d say to let it go. You’re only .5% abv off - you might be on the sweet side of the spectrum, but I don’t think it’ll be bad. Your yeast could be finished and adding sugar to it now will only stress them out more - and there’s no guarantee it’ll keep fermenting.
At this point, take a look at your process. First, make sure you pitch enough yeast and gave it the best head start you could - then look at your mash temperatures (if it was an all grain recipe), looks like it could have had a higher temp that you wanted.
If you truly want to have it keep fermenting, then add Amlyo enzyme - but that will completely dry it out to .998 - you’ll end up with a 5% beer. Honestly, that’s how I like to make my light lagers. I’ll brew a batch and cut it down with water until i’m around 1.03x gravity and dry it out with Amlyo.
[emoji23][emoji23] Nothing to be scared of. They’re just a couple of the numerous naturally occurring enzymes that break down X to Y.
Here are some explanations:
Amylase Enzyme : in a 2-row barley malt mash there’s usually plenty of Amylase diastic power (DP) to convert starches to sugars. In a mash extremely high in adjuncts such as 100% ‘corn squeezins’, Amylase Enzyme could be an asset. I believe ~an hour N of me, Jack Daniels uses 80% corn, 8% rye, and 12% 6-row to take advantage of the 6-row’s high DP to convert the corn’s starch to sugar.
There various different ’Gluco’ enzyme mixes:
Glucoamylase EnzymeThis can breakdown complex sugars to simple sugars to drop gravity very low in dry beers such as Brut IPA.
I don’t think that that is the consensus option; I don’t agree with it. This whole thread is a bit confusing because (I believe) the OP is seeking alcohol from their low OG beer. That alone I find odd. But hey- we all are after different things sometimes.
