Culturing yeast from a peanut shell?

[langsbre]

I know this is a little far fetched. I wanted to culture a yest from a peanut shell and use it to create a lager beer. I had the idea of keeping it add lower temperatures in order to facilitate the growth of the yeast that work better at those temperatures. Does anyone know anything about gather yeast from odd objects, and if so how about lagering?

What makes you think that peanut shells have lager yeast on them?

lol, why peanut shells?

If you're going to choose some random outdoor object, go to south america and find a birch tree. BYO magazine just reported how researches claim to have found the original lager yeast on patagonian birch tree bark. Let us know how it goes.

Where do these ideas come from? Since peanuts actually grow in soil I'd expect it to be easier to culture listeria or salmonella than yeast.

Yeast are hardy, and survive dry periods better than most bacteria. With good plating technique on the appropriate media, it shouldn't be impossible to culture yeast from a peanut shell.

Whether it would make a good-tasting beer, on the other hand...

My point is it would be easier to culture wild yeast from the air than what could possibly be on the shell of a peanut.

Any more info on this theory of peanut shells? I would think peanut shells, if they have any yeast on them, would come from another source...

Pecans might have a good alternative for wild yeast, as nuts are in direct contact with air in tree over entire growth cycle.

Wild yeast can be funky stuff.

Not really on the pecans. Pecans are drupes and the nut grows inside a husk that opens when the nut is released. You'd be better off using the husks then the pecans.

This is true.

Thanks, for the feed back. However, I am still curious as to what mediums you might suggest for culturing the yeast or when to plate from one to the other medium.
