OK, let's combine the two American Lager Yeast? WLP840.

OK, let's combine the two American Lager Yeast? WLP840.

I doubt it, that's the Budweiser strain from St. Louis, via Bohemia, but definitely not California.

I guess what he's getting at is: Anchor Steam California Common lager strain, fermented at ale temperatures, a.k.a. Wyeast 2112 "California Lager" and White Labs WLP810 "San Francisco Lager."

However, for the record, it's not cleaner than Chico/Sierra Nevada/Siebel BRY96/White Labs WLP001/Wyeast 1056/Safale US-05. Lager yeasts at ale temperatures are substantially estery, which is what defines the California Common style and melds so well with fruity American hops.

Well, that was kinda silly.

seymour, I have no idea if you have used Wy 2112/WLP810 but when fermented @ 60ºf or 15.55ºc this yeast is very clean. I used it a few years ago to make an O'fest that turned out very good.

[seymour]

Yeah, I've used it. The recommended temperature range is 58-68°F, so at 60° you might've been a bit colder than me. Mine came out "clean", as in "bright", and as in "not offensive", but I mean estery as a good thing. I definitely detected fruity esters, at least as much as Chico ale yeast which is almost completely neutral.

Ok, I see. I might add that being an O'fest I did "lager" it a bit, although "lagering" was probably 50ºf or so with that yeast.

Well from being at the brewery recently, I can tell you, that the Mash temp and yeast are very wrong in this recipe.

I'll play along - mash temp = 68degC?

[Cozzyb]

That one is more obvious, and yep pretty much spot on.

[Skittlebrau]

So Thornbridge ferment Jaipur with a yeast that only attenuates to 76%? Doesn't that mean, for an ABV of 5.9%, something like an OG of 1.059 and an FG of 1.014? Or am I going badly wrong somewhere here... it just seems a bit high. Not as high as when I first checked the WhiteLabs site and thought it could only get to 70%, but still.

[Cozzyb]

Hi,

All I can tell you is this is 100% the yeast they use. However one thing that might help is the fact that breweries can be 1%(I believe) above or below the number they say, so 5.9% might not actually be the % they come out with everytime, i.e. that FG might flucturate a fair bit.

[Skittlebrau]

I suppise I could hydrometer a bit of Jaipur and get the answer!
