Im vacuum degassing my wine and the bubbles just won stop coming. Whats happening?
A-I’ve had this happen too, even to the extent that I began to suspect that my carboy had a crack in it that was allowing air to be sucked into the wine. It was so bad that I racked the wine into another carboy, filled the previous carboy with water and applied a vacuum to see if there was a leak. There wasn’t, so this is what I ultimately concluded: On that particular carboy, I had just used the Fizz-X drill mounted stirrer and even though I tried not to, I accidentally formed a “vortex” in the wine a couple of times. When that happens, you can force a tremendous amount of air into the solution. I concluded that by applying a vacuum, I was not only getting CO₂ out of the wine, but a ton of air. Had I not been vacuum degassing the wine, I probably never would have noticed the phenomenal amount of air in the wine and am quite sure it would have oxidized and ruined the wine. Thankfully, vacuum degassing got the air out before any damage was done.
