im doing k-97 in about a month or two. what do you think are appropriate styles to go with it?

it sounds more like a kind of alternative ale profile, ~highly attenuating ale, somewhere between english and belgian?

K-97 would work really well in an American hefeweizen.  And... that's about it IMO.  Or well I guess maybe you could play with it in a NEIPA, but just be aware of the tartness and breadiness.

S-189 surprised me in a Rauchbier. That was a split batch, 34/70 was good, might like S-189 better.

In a pilsner it is 34/70 (or Diamond) for me, S-189 is not dry enough.

As far as I can tell, yes, Diamond should be a true lager yeast.  Possibly the same as W-34/70, not sure yet.  One of these years I'll try Diamond, for whatever reason I too have ignored it until recently.

I've never tried K-97.  Just picked up some Diamond yeast to try in a German Pilsner.  I like S-189, but I know some folks don't think it has enough "snap" for the dry side lagers (I find it is nicely rounded and with the right water profile and hop combinations, it is plenty snappy for me).  34/70 has had some subtle lemon notes occasionally, but that could have been a genetic drift issue back when I was serially re-pitching into the teens.

Cheers!

99% sure it's the same heritage as 34/70.

Speaking heritage. Supposedly the origin of Wyeast 1010 is from Widmer vis Zum Uerige. Supposedly, K-97 and Wyeast 1007 are related and 1007 is from Zum Uerige.

Maybe that explains why K-97 tastes similar to Wy1010 (to me).

They are closely related, but not the same.

Lallemand Kolsch yeast is pretty good.

No, not great in my experience.

It sounds crazy, but I really really like Lallemand London ESB Ale.  Fermented cool, it turned out very clean for me.  Its drawback might be its attenuation, which in my experience was about 71% but others have reported it in the upper 60s.  So if you want to try it, consider mashing for a very long time, like overnight, to keep the enzymes working for a good long time, in the hopes that this will keep the beer dry like a Kolsch should be.

Dang....... now I really want to try this!  I'm making a schwarbier this week, I'll split the batch and give it a shot!  I'm pretty sure I still have some London left, will have to check.  If I do try it, I'll try to remember to report back with results, or send me a reminder.

Cheers!

Not IMO.  AFAIAC, WY2565 is the ultimate kolsch yeast.

Just pitched a 4th gen 2565 (4 months old).....after 36 hours, nothing. Looking for a dry yeast for emergency back up.
