I rigged up a vacuum contraption to degas my wines. Works like a charm and costed me just a few bucks. Whipping with a drill took too much time and always has the possibility of oxidizing the wine if not done properly.
ZHI10B vacuum ejector I bought off eBay with the tubes for under $10.
Coiled pipe with trigger valve - came with my compressor.
The end of the coiled pipe goes to the compressor. When the trigger valve is opened, air flows through the ejector and creates vacuum in the tube that is connected to the bung. The pressure in the carboy drops and Gas trapped in the wine is released. I use the trigger valve to control the vacuum and prevent the bubbles from entering the bung/tube.
I was able to degassing 6g in about 15 minutes
I observed two things:
Initially I get small bubbles and then after some time I get big bubbles. I wonder if it is trapped SO2 and CO2 respectively.
My real concern is: would the vacuum in the carboy boil off the alcohol in the wine?
