Storing yeast on beer seems to be recommended over rinsing and storing in water, my question is can i use a cheap store bought say “schaffer” 6 dollar 12 pack beer for that purpose, i really don’t like leaving behind homebrew for yeast storage if i don’t have to, just a thought i had and wondering if this is something people do or why its a terrible idea, cheers
Only if you are not embarrassed to be seen buying it, otherwise it’s a great idea.
i’ll just wear a trench coat and a fake nose when i go pick it up, i don’t think people will notice 
cheers
No reason why not. I doubt the slurry would know the difference.
When I rack the beer there’s always a good quarter inch of beer left on top. I’ve stored the yeast in mason jars for weeks with no apparent issues under the beer. I’d say sacrifice a little home brew for the next generation.
Now, many years ago some of my pals and I did a blind test taste of cheap beer and Schaffer won hands down. I think it was “the one beer to have when you’re having more than one”. We call that a session beer now, but that’s not what they meant in the 70’s!
I find that there is enough beer mixed in with the slurry that rises to the top.
Back in 1975 I worked at the Schaffer brewery in Fogelsville, PA for a couple of weeks as a temp. I think it’s now owned by Sam Adams.
There was a guy who job was to keep the breakroom cooler filled. Almost everyone had some on both breaks and at lunch. A few guys stopped at the breakroom after work to have some instead of stopping at a bar on the way home.
That’s what I do if I can. Sometimes I have extra of what I’ve made and am kegging, and just use the same flat fresh homebrew. Whatever seems best at the time. I don’t top crop much anymore, just harvest the slurry at the bottom of my buckets after racking the new beer to kegs.
