I want to say again that i like the idea of the yeast bank but im not sure how to overcome problem of logistic, simply i have a hard time to justify long drive to pick up yeast if i can get them at lhbs for $3.5-6.5 when shopping for other ingredients anyway. In my case it would work for club meetings or during group buy pickups or for strains that are not commercially available (right now im making starter from bottle of orval that i will be freezing) but this doesnt happen too often

I thought about this as well. I figured I could throw slants in a padded envelope and mail them.

I just realized that there are people who live outside of Chicago.

So I got another question...

I have access to a lyophilizer, and liquid nitrogen, do you guys think lyophilizing yeast will be a good idea? I head that it's possible to lyophilize and then just store in a fridge while it's dry for years.... Also this will make sending them out easier, cuz you know, dry powder and such doesn't weigh too much and you can just drop them into a starter like a dry packet.

i dont know how pros do it but dry yeast are most stable so why dont you give it a try, if you can measure viability do it over time if you cant i can count it with hemocytometer and live/dead dye for yeast so you could send it to me

sounds like a plan, I will probably lyophilize them tomorrow night, and hopefully I'll do a quick dirty test with sugar water, and if that works I will probably send them to you to test the viability

Would it be easier for people if we stored/banked the yeast at my place?

I can check for viability and also offer counts ... Cfu per gram to see what your innoculm would be .... I work as a food microbiologist and have access to many supplies and toys ... Lyophilization is some cool stuff ... Your probably gonna wanna use a small bit of glycerine to keep from rupturing cell walls tho that will increase viability
