Hello all,
I’ve seen other threads about harvesting CO2 from fermentation to purge a corny keg, but my question is specifically about harvesting from a Big Mouth Bubbler.
Can I run a hose directly from the top of my BMB lid to the gas port of a star-san filled corny? Do I need a spunding valve in between?
Will it produce enough pressure to push the sanitizer out of the liquid port into an over flow bucket?
Will I need a weight on top of the BMB lid to ensure it doesn’t pop off? (This has happened using only an airlock)
Is enough CO2 produced to fully purge the keg?
What happens if there is vigorous fermentation and it pushes krausen into the gas off tube?
Can I just leave the overflow tube connected after the sanitizer is pushed out, or should I disconnect and replace with an airlock?
Is there anything else I haven’t thought of with this setup?
After completing, I’ll connect the liquid tube to the spigot and gravity fill the keg, looping the gas line back into the headspace.
Sound like a good plan or am I setting myself up for failure?
Thanks so much for your thoughts.
