I always do with liquid or slurry. Dry yeast no. My technique is pitch the yeast then pour back and forth in a couple buckets then pour into my fermenter. Pretty high tech I know
Transferred beer into my keg and put on CO2.
Full oxebar keg and remainder into a 2 litr cokebottle with carbonation cap.
I need to remember to mark the kegs
Came home to a beer puddle under the kegerator the liquid post on the fermenting keg was slowly leaking all day after hooking up the tap line last night to try a sample. I didn't lose much, less than a pint, but it's annoying and now my floor's sticky lol
