Averagely Perfect Kölsch - Poll #8 - Yeast Strain

WY029 only because the LHBS I prefer doesn't carry Wyeast

 

This is where I screwed up when I order my yeast prematurely and I accidentally ordered WL830 German lager yeast

 

Anybody have experience with omega labs Kölsch?

 

Omega Kolsch I is 2565
Omega Kolsch II is wlp029

 

Not that this should necessarily influence your choice here but I figured some folks would be interested in knowing that via recent genetic testing WLP029 is a lager yeast:

I brewed a Kolsch using WLP029 once and I think that beer turned out nice but it lacked the ester(s) that I prefer in a Kolsch.

Cheers!

 

WLP029 is the easiest as it floccs the best

2565 seems more accurate flavor-wise but needs to be fined or lagered for a really long time to clear. Kolsch should be crystal clear.

1007 also doesn’t like to flocc. It doesn’t really produce diacetyl though which is nice.

I find it so odd that WLP029 is lager and 2565 is ale.. genetically. You would think it would be the other way around based on their performance. 2565 is better at cold temps, Wlp029 doesn’t really like cold temps. 2565 is powdery like a lot of lager strains. WLp029 floccs almost like an English Ale yeast.

I’m probably gonna blend the two. Never done it, been thinking about it for a while.

I actually had really good luck fermenting a large pitch of VT Ale at 56. Might have been my favorite yeast profile of any Kolsch I’ve done. Finished in 4 days and dropped brilliantly clear. Yeast quantity was more along the line of a lager pitch than standard ale.

 

Has anybody used Lalbrew Köln Kölsch yeast? If so, what was your experience? How would you describe the flavor profile? How did the yeast perform?

Cheers!

 

WY 2565 and 1007 produce very different results, in my experience. I have used 1007 for altbiers, which have been clean and malty. WY2565 has produced a noticeable but subtle flavor, maybe the ester @JackHorzempa mentioned -- I am having a hard time naming it because I haven't used it for a few years. In my mind, this flavor belongs in Kolsch, but in my mind, the style is probably too narrowly defined. Still, if I want to learn what wheat is bringing to this style, 2565 is part of my frame of reference.

I do not know if anyone can say anything about Imperial's Dieter, which is not among the choices, but maybe worthy of a write-in campaign? Their website says it is low ester. I've always wondered if it is comparable to 2565. I can say that I brewed an altbier with Kaiser and found it comparable to 1007.

 

Just reread this. Very different is overstating the case. Subtle difference is probably more accurate, as the esters produced by 2565 are subtle.

 

Dieter is just WLP029 in Imperial packaging.

 

In recent communication with a BA homebrewer I stated the below:

“Wyeast 2565 will produce an ester(s) that provides a subtle flavor like a Pacific Northwest Sauvignon Blanc for my palate which I personally find very desirable. So the trick is to ferment on the cool side for an ale but not too cool such that this subtle ester is not produced. I always ferment between 60 – 63 °F with this strain and I have always been pleased.”

I have no way of knowing whether your palate has the same ‘response’ but…

Cheers

 

I hesitated to same wine-like because I've heard it so often and wondered if I was guilty of confirmation bias or if I really felt that it was wine-like. It has been a few years so I don't really remember it too well. I too have fermented this in the low 60s.

 

Has anyone voting for LalBrew Koln used it, and if so, what did you think. Another dry yeast sometimes considered for Kolsch is K-97. My experience with it, side by side with US-05 in a cream ale, was that it was neutral and took a while to clear.

 

Went with Omega but could switch to Lalbrew. Only chosen because these are the 2 options from the poll carried by the store that I am going to order ingredients from.

 

Has any homebrewer actually ever eaten a crushed cape gooseberry?

FWIW, I grow my own actual gooseberries, Hinnomaki Red are absolutely delicious. And... most currants of any color suck. But I like the big sweet Hinnomakis.

 

K-97 is essentially the dried version of 1007. If you’ve never checked out the yeast Genome study and its “family tree”, it’s pretty interesting. I’d suggest it.

I made one beer with the Lalbrew Koln strain. Supposedly the cell count is rather low so they recommend 2 packs for a 12 plato beer, which kinda sucks. Beer was fine. Prolly won’t use it again.

 

Now that you mention it... I can't quite remember what they taste like either. I grew them one summer and made jam with them.
