Thanks Braufessor!
I've heard the 05 connection also. I'm bottling this current high hopped version. So we'll see.

I was wondering if anyone has done any experimentation with pitch rates? I would be curious to see if overpitching effects biotransformation, and how. On the flip side, underpitching to coax more ester production.
wow! very cool info. please tell us all you know. this IS a real problem. i am suffering from it lately. maybe an extended diacetyl rest is the key and fewer dry hops in the primary. never had it happen with 1 oz/gal or less in the dry hop
My latest. Using 2565 Kölsch yeast at 62f.

I used to think it was US-05 as well, then had it happen with WY1056 as well. It may be more susceptible to it though, or it may be that Chico is the most used yeast in the US, especially in IPA, so it just happens more in beers made with it coincidentally. It's never happened to my when I've used WLP095, Burlington ale yeast, and I've done some obscene dry hopping with it.
It's happened to me using US-05, WY1056, WLP002 and WY1318.
I have had those same issues..... which is why I just have gone to gravity from fermenter to keg with lid off.Just an update. Kegged last night. Amazing. Perfect orange color, no bitterness, tasted like juice.
Had all sorts of issues kegging though. Used a pressurized purged keg. The disconnects clogged, remove their guts, worked for a while and stopped. Ended up just poping the top and putting the hose in the keg. Then thought about all the junk in the keg, so I used my autosiphon inside my 300 micron hop tube and transfered to another keg. Just hope I did not ruin with all the splashing and transferring.
To prevent it in the future, thinking about getting on of these.

Anybody else use an inline filter?
Unfortunately, I just had it happen in a beer with WLP002, and I dry hopped that on day 2, as it was a super attenuator and was dropping back big time in only 2 days. I then let it sit like an additional 8 days, and then let it chill overnight. It tasted amazing as I was putting it into the keg, and then after 1 and especially 2 days in the keg, I could taste some diacetyl. It just ruins the beer.When are you dry hopping? I am wondering if an earlier dry hop (even like I have done the past few batches with 6 ounces on day 2) would eliminate it as the yeast would still be very active.
I, personally, have not had much of a problem with this. When I have - ironically - it was with a pliny/Hop Fu type recipes where I was doing the dry hop later in more traditional west coast fashion. Perhaps the fact that they yeast was kind of "done" at this point is one of the problems??? I know the local brewery that was fighting this was fighting it in a more traditional IPA as well..... perhaps the super high hopping works better when the yeast are still very active, and less well when the yeast are out of suspension and can't get rid of the diacetyl????
When that talk is up on AHA I will go back and check it out in more detail - I know it had something to do with the reintroduction of "sugar" that is present in hop material.... Perhaps the cryohops would help this as well as they require half as much...?

I am so super stoked to use Cryohops! However, I don't want to buy them and get another diacetyl bomb. Maybe I'll try a few more IPAs with WLP095 and some hops I've been meaning to try in my freezer. If they all work out, I'll get some Cryohops and experiment with them.
002 is another yeast that drops like a rock..... wondering if US 05, 1056, etc.... they all drop out. Perhaps the yeast that stays in suspension better takes care of it.
When I have diacetyl I pu the keg out at room temp for 5 days or so and vent a couple times. Usually it clears it up.

oh, i tried to fix a couple of the beers by warming them up, but they taste weird after re-chilling. they're just lost at this point. I did think about throwing in some Brett and racking them to a carboy to see what happens.
I have had those same issues..... which is why I just have gone to gravity from fermenter to keg with lid off.
I would think a filter would plug up something terrible..... never tried it..... just don't see how liquid would flow when the hop particles started to build up on filter.
Brau, what day do you add the 6 oz to primary and on what day do you rack to keg? Is that pretty standardized? When was the last time you had diacetyl after dry hop/kegging?
thanks for feedback guys. I got em out, hopefully the taste clears up.
I think that's just the azacca hop that tastes that way

Add me to this camp. I have tried the fully closed transfers many a time and just end up clogging the poppets (even stainless steel poppets I thought looked a little bigger).
How the hell do people avoid this? I hate going through the trouble of Star san water purging a keg just to have to pop the lid because the damn poppets clog. If you dry hop in the primary it seems inevitable, even if you can push with co2.
Maybe keg hop is the solution. Water purge, push to keg, pop top quickly after filled and dump in hops and seal up and purge again...

The diacetyl issue after dry hopping "seems" to be related mostly with the yeast 05, (at least in this thread) not other Chico strains.
I still wonder if the dry hopping with ALOT of hops, with certain yeast strains, raises the post ferm PH during diacetyl rests, causing the yeast to be stressed.
This may cause the yeast, that is already in a hostile environment (alcohol) to leach out D? This is entirely my speculation by the way.
I am almost positive that it is a documented fact that it does elevate pH..... what impact that has on this issue, I am not sure.
pH and diacetyl:
http://byo.com/bock/item/546-diacetyl-homebrew-science
Looks like it may be that the conversion of the precursor is slower at higher pH. That *could* mean that though we think the diacetyl threat is gone when we rack, it is still slowly being created and continues to be after we rack to keg and basically make the yeast go dormant. Perhaps if we mash at a lower pH or adjust the kettle pH to a lower level, we can push the final beer pH a bit lower and speed up the conversion to diacetyl so the yeast can get rid of all of it. Brau, I think you measured your kettle pH for a long time. What do you target for that?
Or, it would seem to indicate that it might be better to dry hop later in the fermentation so that the diacetyl is mostly gone. That doesn't alleviate the problem of more diacetyl being produced as the yeast are "awakened" by any thing going on with adding the dry hops (eg release of sugars or some amylase activity from the hops.)
Pretty sure this is normal...... right?
