I'm sure there are about a million threads on this, but most systems I've ever seen for pre-cold crash C02 capture seems to be some jerry-rigged plastic bag. At least anything that works with a non-pressurized carboy style fermenter. Is there a better way? It would have to fit in my chest freezer ideally, so it will have to be very low profile on the top. Searching for a commercial turnkey solution; nothing seems to be out there either.
