I have been trying to harvest the yeast out of some New Glarus Spotted Cow, so I can start working out a clone. Problem is, I can't seem to get it to grow.

Has anyone ever successfully harvested from these bottles? I've searched on here and google, to no avail.

I've tried two starters now, the first with 800mL and 1/3c extra pale dme, and 2 slurries from the bottles (fridge temp). Second was the same wort, and three slurries from room temp beers.

Both times, there was no activity at all after 5 days, nor was there more yeast in the sediment than what I put in there.

Any of you hands have a suggestion?

Thanks,

Are you certain that the bottle yeast is the same strain as the fermentation yeast?

Spotted Cow is fermented with Wyeast 2565 Kölsch yeast. It is available at most retailers.

Sorry if that kills the mystique. Ferment it cold around 60ºF.

Doesn't ruin anything, I was gonna use a Kölsch if the harvesting didn't work out. I am just curious how you know this? I haven't read anything other than the yeast is probably proprietary, and that Dan is fond of Kölsch yeast.

Everything I've read, leads me to believe that the yeast is the same as the fermentation yeast. Don't see why you'd go through the trouble of filtering yeast out, then adding some back in......especially if it is widely available Wyeast.

Thanks,

I heard from someone who used to be an assistant brewer there.

Don't know about Spotted Cow, but a lot of Belgian brewers do this to foil home brewers attempts to "pirate" their beers. That said, doesn't Spotted Cow claim to be unfiltered?

Yeast strains mutate over time. Even though Abbey, Abbey II and Belgian Strong Ale (Wyeast strains) were all originally lifted from Belgian breweries, some were more than 30 years ago and you still wouldn't get an exact copy.

Are you sure Spotted Cow is bottle conditioned? It's widely available in quarter barrels around here which would lead me to believe it's force carbonated.

The label claims that it's cask conditioned.

Naturally cloudy we allow the yeast to remain in the bottle to enhance fullness of flavors, which cannot be duplicated otherwise.

Expect this ale to be fun, fruity and satisfying. You know you're in Wisconsin when you see the Spotted Cow.

Thanks Jack, I had another tab open ready to copy the info over.

I'm originally from Plymouth, just so's yous guys don't get the wrong idea about me. In arkansas for school (since everyon else in this thread is from WI).

The part about "leaving yeast in for fullness of flavor" and "naturally cloudy" is what leads me to believe that it is the same yeast. I just can't figure out why it won't grow out of the bottle, so I can save $10 on my next trip to the LHBS.

Anyway, I have a few more bottles from this case left. And some friends from up there are headed down tomorrow for some duck hunting, so I'll get another supply to tithe me over. (yes, me - hoppy beers give me wicked headaches ; swmbo prefers organic revolution)

Thanks again,

To be fair, I've always wondered why there's never any sediment in Spotted Cow bottles if it really is cask conditioned.

Perhaps they mean the only do not filter the beer. It could still be force carbonated with residual yeast in the bottle. This is what I suspect they do.
