Ive read with interest about yeast culturing.

What is it and how do you go about it?

Cheers :huh:

It's a way of building your own yeast bank. As you buy or trade for unique strains, you build your library. I guess it's ultimately a way of ensuring that you never have to buy yeast again.

Doing it is pretty simple. The most widely accepted way is to grow yeast on agar slants in sterile sealed test tubes. Here's a post that discusses it. Search the forum; there are lots of others.

Hi guys,

Just wondering if there is any way of extracting yeast from commercial beers that have no sediment?

Thanks

Not really Andrew,

If there is no sediment, then the beer has probably been filtered and maybe also pasturised.

Its possible that a beer has been bottle conditioned and the brewer has been skillful enough to manage it with so little yeast that you don't notice it - but mostly thats not going to be the case.

You could try out the method for culturing up yeast from a Coopers bottle, just to see if you can get anything to grow, but if you do ... there is a fairly big chance that whats growing is something that floated into the bottle while you were mucking about with it, rather than yeast from the brewing process.

Not usually, most yeast is filtered out and some manufacturers pasteurise their beer as well.
