Default Do small breweries propagate their own yeast?

Just curious if small breweries just getting started usually bought yeast bulk or propagated their own.

i have bben to only one small brewery and i asked them this very question. he said that they have some yeasts that they will harvest but no more than 2-3 times. after that there is risk of mutation. he said that they did have one or two yeasts which were given to them in germany which they pay a lab to cultivate.

Most of the small guys round here just use dry yeast bricks. FWIU.

Seems like that would be a huge part of the cost if you needed to use liquid yeast for some specialty beers. A brick of yeast sounds awesome.

It's upsetting how many more strains are available commercially in dry form.

Depends on the brewery but I would say 90% leave that one up to the pros. Some get cultures from Wyeast or White Labs in much larger pitchable quantities and use them for a couple of generations. I know a couple of breweries who use dry yeast from Fermentis. When I was working at Page in Minneapolis we used to go over to the Stroh's brewery in St Paul with a bucket and tap a fermentation tank for yeast. (I'm guessing that situation was fairly rare!)

My favorite local brewery propagates their own yeast.

There's a little about it on their blog here: The Potable Curmudgeon: NABC brewing schedule for the remainder of 2009 (part one).

Mississippi's only micro, Lazy Magnolia Brewery, uses all dry yeast. They use them for a few generations and toss em. The brewer told me all the ones they use are available to us homebrewers, I quipped about that being a bunch of packets to open

Schlante,

Why is it that they choose not to sell to us? Is it a storage problem or something..... I can't see why except they would not find it profitable. Is my money no good!
