Didnt the tree house yeast toptic found some results on temperature schedule by photos?lol I thought the same when I read that line saying to myself “so you're underpitching and hit temp targets”
Maybe you remember which photos temps im talking about (in the tree house thread).“Carefully stressed” lol
The flat out science is that esters are created mainly during the growth phase. To place more stress during growth or to make the growth phase take longer are what does it. I’m sure they are using a combination of both methods.Didnt the tree house yeast toptic found some results on temperature schedule by photos?
I seem to recall people playing with driving the temps up and down.
Personally I would guess they do the "british" way te encourage esters. Pitch at higher them and cool then let it free rise again.
I know it’s equivalent A20 is a low floc strain. The A04 barbarian has a high Floccuation ability and A24 is pretty much in the middle. So you technically shouldn’t have decanted the starter of the two yeast because the blend much higher in the connan strain since it flocs betterQuestion for the A24 yeast blend users
@Dgallo and others.
I made a 1 liter starter of wlp644 and a vermont strain. When crashing both starters to decant I noticed even after 24h of crashing at 1c the wlp644 was still very hazy. Especially dense haze near the bottom. I mixed them and pitched them in my beer.
Wondering if anyone can comment on the flocculation of this blend.
Good point, lets see how this turns out. I got the same beer fermenting with vermont only to compare.I know it’s equivalent A20 is a low floc strain.

I soft crash for 36hrs and that seems to do the trick but there’s no reason you couldn’t go longer. The later generations seem to flock better so I’m guessing the a04 becomes dominate after g3 so I usual just don’t run it very long and just use a fresh pack. I’ve never done a side by side so I’m interested to see how the ester profiles comepare so def post the results of thatGood point, lets see how this turns out.

I didnt decant as much, tried to keep as much yeast as I could from 644.
Could you comment on the flocculation of a24? Do you softcrash? If so how low and long and does it clear up properly?

Yes sir, that’s how I run a24. You can even push it 75/76 but if it get above that the a04 in the blend throws some fuselJust to add here when I asked imperial about generation drift in a24 they said not to decant, just like you mentioned. As long as you overbuild your starter (as compared to harvesting) the balance should stay pretty much 50/50. They did mention there might be some drift but it shouldn’t be that big of a deal.
I’ve got my first use of a24 going into a fruited blonde with Citra today (beach beer in a couple weeks). 1l Starter spun up Wednesday, shooting for .5 pitch rate. Didn’t get a lot of Krause but there’s plenty of yeast in the starter, it’s crazy hazy.
I went back in your post history dgallo and you mentioned pitching at 68, free rise to 72 then push to 74 over the first few days? You still do something similar?
Could you share some more on that chamber?
What kind of device are you building?
Just got it done. I had to build a sliding shelf in the fridge so I could pull the fermenter out to attach the hop chamber. The three way valve is so I can attach a vacuum pump and CO2 at the same time and alternate rapidly back and forth between vacuum and CO2 by turning the lever.

Sweet tortilla Jesus that looks so rad, where did your source all pieces specially the chamber?
That kinda goes way back to the og tired hands milkshakes, where (rumor or not) they would add green apples to the boil for their high pectin content. That was only for the milkshakes tho, and they clearly had plenty of haze in their other ipas without the added pectin

Love it! So you can remove this thing from the top without introducing o2 and then attach something with a blowoff?Just got it done.

What size TC does it neck down to? It looks small. Are you worried about the hops getting jammed up in it?Yes. The TC valve and blowoff stay on the vessel during fermentation.
For those using Fermonsters with floating dip tubes, what exactly is your process with hoppy beers?
The last two batches I've had issues trying to pull beer out through the dip tube. No matter how much I crash there is still some hop debris on the surface that I think is clogging the dip tube but even after blowing it out with CO2 it still doesn't flow. What PSI are you using to push the beer out and how are you avoiding clogged poppets?
I don’t experience that when I crash. They are literally all settled after 36. @Loud Brewing modified his CBD in his floating dip tube a little so he may have a solid answerFor those using Fermonsters with floating dip tubes, what exactly is your process with hoppy beers?

I always cold crash to 36f for a minimum of 24 hours which settles most everything out. As far as pressure, it usually only takes 3-5psi to get siphon going into keg with a nice moderate flow that wont disturb anything. I also removed the poppets from both the liquid out post (on fermonster lid) and ball lock fitting on the fermenter side of the transfer line which helps reduce places that will trap particulate and increase flow a bit maybe lol.For those using Fermonsters with floating dip tubes, what exactly is your process with hoppy beers?

No they both attenuate well so even if it were primarily A04 it should ferment out. 1.019 does seem high even though you mashed out for alpha amalyse. What percentage of the gist was flaked/body building grains? Because that could certainly account for the higher fg. Also how long has it been at 1.019I didn't think about this and unfortunately missed this before overbuilding a starter, splitting it into two mason jars and decanting the one I pitched. That said, it had a good 72 hours in a 34F fridge and looked fairly clear above the yeast.
However I just pitched that into a well oxygenated step mashed 1.060 wort (148-30, 154-20, 164-20) and it finished at 1.019 which I was not expecting at all. Was hoping for more like 1.014 or so. First time using this yeast...is this normal? Could it be due to the decanting?

With roughly 5lbs of less fermentable grains in a 1.060 I’d say you’re right where you should beHere are the adjuncts/specialty grains

It's been there for a while. I just checked it with a hydro after a couple of days of no activity or change on my tilt and this is day 10 which is WAY longer than my ales normally take to ferment out (especially a 1.060).
I use a regular unmodified ball lock on the liquid out post that has had the poppet removed during fermentation. Then during cold crash I hook up the gas side and run1-2 psi to prevent suck back.I've thought about removing the poppets but that seems like an o2 nightmare. What is your process for this?
Yeah carb caps are awesome, I use them for everything. Removal of the poppets is not necessary if you cold crash and avoid the bottom trub like I said, but it cant hurt. One more thing to add is that I cut several slits in the small aluminum pick up tube that attaches to the float, that way if you do manage to get a clog in the main opening you will still get flow.Nice...i used to pull poppets on the receiving keg but never from the fermenter. I like the crushed pet/carb cap trick. It's amazing how many uses those things have.
Anyone use the 2018 Azacca from YVH ? What profile did you pick up and at what rate did you WH/DH?
