I use a sanitized spoon and spoon it into sanitized mason jars, taking care not to let “stuff” fall into the bucket as I work. I’ve also used a paper towel drenched in sanitizer to wipe down a section on the rim of the bucket where I can pour from (but I prefer the spooning method because I can target the yeast cake and avoid most of the beer; granted, I put a few spoonfuls of beer on top afterwards to reduce headspace in the jar). This is just how I do it and it’s been working pretty good for me. I’m sure other folks have more creative/effective ways that work for them.
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.
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?
Well, for starters (no pun intended), the sanitizer may have dried leaving the surface open for contaminants to settle, in which case you would be “washing” those contaminants into the jar you’re using to collect the slurry.
Sanitize a jar and stick it right in the yeast sludge and scoop it right out. Seal the jar, then rinse off the outside of it, dry it, and label it. Or most often, I do the same with an old White Labs tube. Works great.
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.
My personal rule of thumb, based on my own anecdotal experience, is that refrigerated yeast will keep for roughly 9 months. After that it gets tossed, at least out of my own refrigerator. YMMV.
I’m pretty technical about this. I grab a Pyrex measuring cup, tilt fermenter, scoop, and then fill pint jar. I do try to eliminate trub and break before fermentation. I’ve never had an issue doing it this way. Really easy as that.
