Nowadays, homebrewers can choose from lots of different yeast strains from various producers and yeast banks. As a reference, I’m putting together all those that I know of and that explicitly cater towards homebrewers. I’m not including commercial or scientific yeast banks because they often do not sell their yeast in homebrewing quantitites for homebrewing prices. Also, if you know of any other places or companies that produce yeast for homebrewers, please let me know in the comments, and I’ll add them to the list.
Liquid yeasts:
- White Labs
- Wyeast
Weihenstephan Hefebank sells some of their yeast strains for homebrewers through schnapsbrenner.eu- Fermentum Mobile
- The Yeast Bay
- Saccharolicious
- RBY Laboratories
- Imperial Organic Yeast
- JasperYeast LLC
- East Coast Yeast
- Bootleg Biology
- RVA Yeast Labs
- GigaYeast
- Omega Yeast Labs
Dry yeasts:
Update 2015-11-25:
Another dry yeast supplier I found: Brauwerkstatt
Update 2015-12-25:
Escarpment Labs has recently started making their yeasts available to homebrewers in Canada.
Update 2017-11-02:
Brewlab sells slants of a great variety of British yeast strains for GBP 6.00 per slant plus GBP 5.50 shipping within Europe (GBP 2.50 within the UK).
Perhaps this huge collection in the UK (National Collection of Yeast Cultures) is also of interest:

They seem to sell also, although this seems to be targeted at commercial brewers in the main.
Excellent work, by the way!! Many thanks.

Sorry, forget about NCYC. Unlikely to be interesting / relevant for homebrewers (as you ahve already written above).
Best regards, Tilo
How about this one?

Based in the US I believe but it appears he’s done yeast exchanges over larger distances as well.
