Hydromel Carbonation

<< < (2/2)

Interesting! My only experience/ knowledge on the subject come from NAUI. But I'm sure the human body and nitrogen are different that CO2 and beverages.

I guess I should be glad that my issue isn't regarding diving since those stakes are much, much higher!

In my google searches I did find a few references to the same phenomenon, but no explanations as to why it happens.  I may play around with hose length and pressures to see if I can figure it out.

At 18psi and a 2.5foot hose, I'd expect it to decarbonate very quickly. The rapid pressure drop at the tap causes it to degas quickly. If it were beer and could hold the bubbles, you'd have a glass full of foam.
This is a great resource. Look at Chapter 5: A Matter of Balance.

Thanks for the link!  I did finally end up getting it to hold onto a bit of carbonation by using a soda bottle and carbonator cap in the 30's, but if I decide that I want to serve it directly off the keg then I'll have to set up a new cobra with an extra long hose. I still suspect there is another factor in play that doesn't apply to beers because they rarely drop below 1.000, but I'm stumped.

You may be right. I think sparkling wines are carbonated to levels far higher than 3atms and that may be why.
