Updating my fermentation process/schedule

[jb1986]

Hello,

I'm currently fermenting an american pale ale, very similar to brewdog moshi moshi. I use my own hops grown in my garden and I went for us-05.

Now that I have a glycol chiller i'm thinking about playing with temperatures during fermentation & dry hopping. Here is my current plan:

- 18°C (64°F) during 6 days
- 18° First dry hopping with 50gr cascade, 50gr centennial and 50gr colombus (2 days)
- Wait until final gravity is reached and purge yeast.
- 14° (57°F) second dry hopping again with 50gr cascade, 50gr centennial and 50gr colombus (2 days)
- 5° (41°F) cold crash as fast as possible for 5 days with 1 purge after day 4.
- Bottling

Any thoughts ?

pretty much how I do it, except I ussualy ferment that at 68°F instead

if you have not used a glycol chiller before just be aware of the glycol temp. try to go too cold too quickly and you will just freeze the coil. ice insulates cold amazingly well.

Consider a diacetyl rest of about 5F higher than fermentation temperature for 2-4 days after gravity has stabilized. Then cold crash.

Otherwise looks ok.

Hops in a bag?
That's a lot of hops in what I'm assuming is a 5 gallon batch.

 

[Herm brews]

Seems like a notable loss of precious wort in a 5 gallon batch.

Looks good to me JB as Herm said make sure you account for hop absorbtion to hit your final packaging volume.

I'd like a taste of this beer when it's done

I'm expecting Dank and pine from them hops...

That's exactly what I was about to ask when I connected. Fermentis advice is 23°C (73°F) for ales but in many other places I saw 20°C (68°F). Very similar to your +5°F. Should I do it before or after the second dry hopping? And should I wait until gravity is stable or start a bit earlier?

- 18°C (64°F) during 4 days
- 18° First dry hopping with 50gr cascade, 50gr centennial and 50gr colombus (2 days)
- 2 days diacetyl rest @ 20.5°C (69°F) once FG is reached (gravity stable during 3 days).
- Purge yeast
- 14° (57°F) second dry hopping again with 50gr cascade, 50gr centennial and 50gr colombus (2 days)
- 5° (41°F) cold crash as fast as possible for 5 days with 1 purge after day 4.
- Bottling

My second question would have been: should I do the first dry hopping at day 6 or should I do it at gravity 1.020? That will probably be at day 4 (currently 1.025 after 3 days)

Yes, hops in a bag. Or spider. Or loose ..(never tried)? Centennial and cascade come from my garden, colombus is in pellet. I have 23L (6 gallon) in my fermenter. Any advice here?

You can do it before or after the second dry hop. The goal is to start when FG is stable. Whether you add hops or not really does not impact what the yeast does (absorbing and processing 'off' flavors). Your plan looks solid.
