Hi.I've often thought about collecting co2 from a ferment but not done it yet. I have recently replaced my airlock with a blow-off pipe which runs into a 6 pint milk bottle & bubbles through a couple of inches of starsan mix. (See photos)
In theory:
After reading another post, have had the idea of placing the plastic milk bottle set up into the bottom of a spare 25 litre plastic fermenting bucket (lid on but able to vent through small hole on top) which hopefully should fill with the co2 & push the air out above it. This would have the advantage of sucking back co2 instead of air when I cold crash & bottle.
Not sure if I could work out a way of purging all of the bottles though. I'm not sure if o2 exposure is very high within the bottles. I suspect most of the exposure to the air is the larger surface area on top of the beer within the fermentor when air is sucked back in as the liquid level drops. So doing this co2 reclaiming should eliminate or at least reduce it.
Anyones thoughts?
