Reader Tip: Use a Carbonation Cap To Assist with Closed Transfer Racking

Thank you to Twitter Follower Josh @beardlywine for this tip! Let’s be Friends! – 8 Ways to Connect

Josh uses carbonator caps to assist with closed transfer racking to kegs.  If you look at the photo he shared, he’s putting a small length of tubing on the cap and then feeding that through the airlock grommet hole of his fermenter.  This same process could be adapted to work with other styles of fermenters.

Carbonator Caps

New offerings regularly pop up.  Search Amazon for “stainless steel carbonation cap” to see what’s out there.

Although it doesn’t matter a whole lot for this application, I recommend looking for a model that’s compatible with your intended application that works with both gas/grey and liquid/black QDs. This will give you maximum flexibility.

    Great tip! Every article I’ve seen for closed transfer were with glass carboys, always wondered if people could do them with buckets.
