I just wipe some sanitizer on the upper part of the bucket and pour through a sanitized funnel. I use the yeast shortly after harvest or else I toss it after a few weeks, though.
It was sanitized before the beer went it. What's the point?
Sanitize a measuring cup and scoop it out.
I use wide mouth plastic containers for storage, so no need for a funnel. I also don't bother sanitizing the rim of my bucket. It was sanitized before the beer went it. What's the point?
How long do you keep a jar of yeast before you decide to throw it away? I've brewed with a repitch of 1056 that's been over six months and haven't noticed a problem.
