Very interesting. So if I understand this correctly- I can simply rack my beer, swirl the remaining beer ((1/2 inch or so), pour into sterilized container and decant liquid with yeast after a brief settling time to a separate sterile container and store that beer and suspended yeast for later use? With Brett I guess I'd worry about it continuing to propagate in whatever sugars may still remain and in a closed container may not be a good idea. Could always store with an airlock I guess. It'll be in the fridge so certainly going slower whatever the case. Feeding it extra beer up front seems less necessary if I expect to use in a few months.
