Ive always used the water filled airlocks for wine fermentation in the demijohns. How effective are the CO2 releasing bungs?

this is it. Not sure if it would cope with initial fermentation or whether just for racking, but allowing co2 release in absence of air entry ?

I have those,They are not meant to cope with the co2 from an active fermentation.

They are more a safety bit of kit for wine maturing in demijohns.
Thanks John i knew i had seen them before but couldn't remember where.

Water in air-locks? Pfft! Surely it's small batch vodka at the very least? 😃

Agreed - long term storage only. I you're worried about normal airlocks - ether use glycerin in them (won't dry out) or some water with steriliser in. Also use the red cap or a bit of cotton wool to stop the beasties crawling in.

These look great for aging stuff in demijohns without having to remember to keep topping up the airlock; have you got a link?
Safety Cork for gallon demi-john - eBay or other places :-)
