I’ve read this too, but never noticed that distinctive Kolsch flavor in an alt…
I did however just brew a dark Czech lager recipe with a Kolsch slurry and came out nice. The heavy amount of darker malts helped mask the winery flavors and it turned out very clean.[/quote]
Yeah, the 2565 is supposed to give a slight wine-like, maybe ‘tart’ character (very subtle) and that would depend on the temp of the fermentation. It’s a relatively neutral strain but I think it produces the right character for a Kolsch and I really like it. I fermented both of these kolsch beers cool (near 60°) and got very clean ales in both cases. If I were to make a kolsch, it would be with 2565, no question. I think there are alt and kolsch yeasts by White Labs (029 and 036, I think) but I haven’t tried either one. This WLP011 seems like a nice yeast and I’m always looking for ‘other’ ale yeasts because I seem to keep using the same ones over and over.[/quote]
I’ve always used the 2565 as my lhbs carries this. I used to ferment it at 63-65 and the last time the in-laws were over, they said it was too fruity. My latest rendition is on tap now and I held fermentation right at 60F and was super clean…
Until the yeast dropped out (7wks cold conditioning and gelatin) and the Kolsch yeasty flavor absolutely shined through perfectly.
