Any idea if or when this will be available?
A quick check shows it available in Australia and New Zealand and at least one HB forum post says it will be in North America by year end. Like when Brewtan B first came out, it was available through Australian sources before it hit the U.S. homebrew market for some reason (less red tape, maybe?)
Thanks! Can’t wait to hear more about this yeast. I have been waiting for a “true” kolsch dry yeast strain. I wonder if this will fit the bill.
It will be interesting to see if it makes an acceptable Kölsch.
That would be awesome.
I would also like to compare it to US-05 and Bry-97 for APA’s and Ambers.
Hello all,
I am extremely pleased to let you know that Köln is now in the States and we are fulfilling orders as I write. It’s been very much anticipated and I’m very excited about this! Feel free to contact me at eglass@lallemand.com with questions.
Cheers!
Woot!

Coming to Canada?
I don’t think I’ve read another yeast description with this statement: “Expression of a B-glucosidase enzyme gives this ale striain the ability to promote hop biotransformation…”.
Sounds interesting. Not sure what it means though.
“Simply put, biotransformation is said to occur as a result of the interaction of hop oils and active yeast, leading to a transformation of certain terpenoids into terpenoids that weren’t originally present. A fascinating concept that many have posited may be responsible for the qualitative differences between New England and other styles of IPA.”
Basically when you hop in the fermenter (during active fermentation or after fermentation is complete) changes the results.

Label Peelers has this for $6.14 shipped. I bought a pack to try.

Hey thanks for sharing that. I probably never would have read the description lol. Now I’ll have to play around with it.
I’ve got a couple of experiments on the go with this yeast. I’ve got a spilt batch kolsch cold crashing right now - 2565 (the incumbent favourite) vs Koln. Early visuals suggest Koln is a significantly better flocculator.
The other experiment is a using Koln in a NEIPA based on the biotransformation blurb on the website.
I’ll report back with further findings.
From what I have read so far, I will need 2 sachets of this yeast for 5.5 gallons of wort. Cheaper to use liquid yeast.

Why two packs? The specs seem the same as all dry yeast.

You want (approx) .75 to 1.5+ million cells per mil per degree plato - the lower end would be the spectrum for ales and the higher end the spectrum for lager. For a kölsch you *may want somewhere in the middle since it will ferment on the cooler side. I have not looked at the specs on this dry yeast yet but generally speaking dry yeast has more viable cells than a pack of liquid yeast so, depending on the beer you are brewing you may very well need more than one smack pack or tube/vial of yeast if you aren’t making a starter or growing yeast.
One thing about dry yeast: it ships in the summer without ice.
Another thing: it easier to store than liquid so more shops sell it. My LHBS (just a corner in a health food stores sells dry but not liquid).
All that to say, I think the manufacturers of dry yeast are recognizing they have a value proposition and are starting to charge accordingly. They also have lower costs (they don’t need to refrigerate either). So, hopefully they stay lower priced in general.
