I've never heard of K-97 before this thread.

I haven't tried them back-to-back, but they seem a bit different. They definitely are both strong top-croppers and are pretty sticky. Some people call it a "Koelsch" strain, but some people are wrong. It doesn't have the white fruit (pear/apple) and vinous esters you'd expect from a proper Koelsch yeast. K-97 is much closer to 1007 than to 2565. K-97 ferments cleanly and matures quickly. It's powdery, too, so it needs finings or extra time to drop bright.

That's a west coast strain, it says. Where are you seeing it being referred to as a Kolsch strain?http://www.northernbrewer.com/shop/brewing/brewing-ingredients/beer-yeast/danstar-american-west-coast-ale-yeast.html
Nope. K-97:http://www.fermentis.com/fo/pdf/IB/EN/Safale_K-97_IB.pdf
Gotcha, I'd never heard of K-97 before this either. Didn't see it on Midwest or Northern Brewer.
