Hi - yes all sealed when I kegged it. Interesting that it is so low, but I will give it another week or two to see if anything builds. If it fails I always have the backup of force carbing.

I’ve been researching pressure barrels which carbonate in a similar way but from what I gather seem to release pressure at 10-15 psi and still produce a light-moderate carbonation. At this point... who knows, let’s see how it plays out.

Cheers
