I don't like Wyeast 2565?

[brownni5]

About a year ago, I got some Kolsch yeast slurry from a friend - he said it was Omega Kolsch 2. I brewed a simple Kolsch with it and immediately disliked it. A weird aftertaste I couldn't quite explain, and even after a month in the keg, it had not cleared, which really doesn't bother me, except that the description says it clears pretty good for a Kolsch yeast.

A couple months ago, I brewed a Bier de Mars with it. Again, I don't like this beer. I'm planning on adding Brett to the keg to try to salvage it. A weird tart-like flavor that I think is from the yeast - the same flavor I recall not liking from the Kolsch. Almost 2 months in the keg (and gelatin fining), and this beer is not clear.

In the meanwhile, my buddy tells me it might have been Omega Kolsch 1, but looked it up and realized he had bought Wyeast 2565. That would explain why it isn't clearing.

A Brulosophy XBMT between 2565 and WLP 029 showed the two were noticably different, and that some described unpleasant yeast flavors from the 2565. Does this jive with others impressions of this strain?

Maybe it isn't tart, something I can't really put my finger on, just know I don't dig it (and I dig me some tart/sour beers).

WY2565 has a somewhat "vinous" wine-like complexity to its ester profile which I find more pronounced in the higher 60s. That's probably what you're not liking. Personally I love it and I use that yeast a LOT.

Maybe that's it. Since I thought it was a different strain, I fermented it warmish, 65-68.

I love 2565, but I don't ferment it as warm as you do. I keep it at 60F for 10 days, then 65 for 3 more, then crash to 33ish.

I find it takes four weeks to be its best and brilliantly clear, but it's worth the wait.

That could be the culprit. I've only used 2565 a couple times, 029 a few more times than that. I prefer my kolsch that used the 2565, but each of those were fermented in the mid 50s or so, and then stored in an ambient ~47-50F basement afterwards. It doesn't not clear well at all, but I never got any type of flavor that you're describing from it. 029 is a good enough yeast too, but I think its just clean and doesn't add much to the party. Drops like a rock though.

Maybe it's worth another try then, this time cooler.

I've made Kolsches with 2565 but my personal preference is the GigaYeast-021. Then again, personal preference is what make me hate lima beans, so, YMMV.

I really like the Giga Yeast that I've tried . My LHBS only had the dry yeast for kolsch. I think it was K97. Turned out solid . I normally use liquid yeast but I'll stick to K97 for kolsch

 

[balrog]

I did K97 once and it was tart/wine like the 2565
The GY021 was richer, mellower, still white wine ester

I'll have to try it . My LHBS doesnt carry GYso I have to order. The only one Ive tried was GY054 I believe . Really good .

I was put onto GY021 in this thread, I tried it and liked it and have stuck with it for Kolsch while I use WY for just about everything else.

Have you completely ruled out an infection? From the description (off taste, not clearing) there might be something else going on. The yeast sample from your friend might have been infected in harvesting and handling. Did you use the same keg on both the Koelsch and the Bier du Mars? Might be a common thread other than the type of yeast.

K-97 is the dry version of 1007.

2565 you have to use finings or lager for a really long time.

wlp029 is much easier to work with but I personally find it of meh. I thought the Gigayeast Kolsch was similar to wlp029.

Anyone ever use the East Coast Yeast Kolsch strain? I guess it’s the Brewtek CL-450 strain. It intrigues me.

hah, my old thread from last year! I still like olives in beer...
