adding dry hops while fermentation is ongoing

[stijn26]

Hi,


After some reading up about bioconversion of hop oils I wanted to do the following:

- Throw in a first load of pellet hops when the SG is 1.015 (I always get 1.011 FG).
- Throw in the second load of pellet hops the day after this first load
- Let them soak for 2 more days
- 1 day cold-crash
- package

So this is the case for the BRY-97 yeast.

But in my most recent batch (which I brewed yesterday) I used Wyeast 1318 London Ale for the first time.
I splitted the batches and today I took the SG's from both.

SG from 1318: 1.020
SG from bry-97: 1.031

The OG from the beer was 1.037.

I'm now wondering, I assume an attenuation rate of 73% for both, both resulting in FG 1.011. So probably in 10 hours the 1318 has reached an SG of 1.015, at that time I will throw in the first load of dry hops.

So if I will do that, this leads to only 6 days between pitching the yeast and packaging (for the 1318). This seems very fast?


What do you guys think of my plan?

It does seems fast. Why are you putting in the dry hopping before active fermentation is complete?

Adding the dry hops prior to ferm being complete is a trait of a NEIPA. I do not know how the biotransformation works but by doing that, it creates chemicals/flavors that aren't there in a typical dry hop. This will also result in some additional cloudiness. What kind of beer are you aiming for?

Because yeast process some compounds into a mixture of other ones, which can be appealing - but a lot of this processing happens within 3 days of pitching. See eg

Thanks for the info, Rob and NB. Increasing the concentration of geraniol is not typically something I would want, but I also don't enjoy NEIPAs, generally.

That's more of a hop choice, but adding hops early will *reduce* the geraniol as the yeast convert it to other things.

I think you're rushing it a bit. Not sure why you've settled on dry hopping 1 day apart. I would add your biotransformation hop as planned and then wait for the beer to hit FG before adding the second dry hop. I'd let the yeast tell you when its time to try hop, not just arbitrary dates you've settled on.

Yes indeed. So I added the chinook a few days ago when the SG where 1.016. Now waiting on final FG to add the rest of the dryhops.

The type of beer. Hard to say, its a session ipa where i wanted some elements of a neipa in it. Lets just call it an IPA? Its hard for me to think in boxes [emoji16]
