It depends on how much gas was dissolved, or basically, how long its been setting at a cartain temperature. I've had a few that were already degasses by the time I got around to it, and one little demon I had to degas for about 10 minutes, three times a day for two days.

I spent quite a bit of time trying to degas using a mityvac. I took a sample and shook it with my hand covering the opening of the tube. It fizzed up and still made the puff sound. Would it help if I got a brew belt to heat the wine up and try again? I`m running out of ideas.

If the wine is usually at 75F it will degas easily. You could try racking it, and put a crimp in the racking tube, like a bend. This works for many people.

Just keep pumping that mityvac! It only removes 1 cubic inch of volume (not directly proportional to the amount of gas) per stroke. It takes a long time to remove a lot of gas with it. Keep going. I find that the double handed "one on the handle" and "thumb and index finger" approach works well.

Ended up breaking the mityvac handle off. I don't think I even had it for 30 days. Hopefully Harbor Freight will replace it. I also got a brew belt and warmed up the wine. Spent another 40 minutes with drill mix stir. Tested for Co2 and still making the 'puff' sound. I will try to rack with a bend in the tube to see if that will do it. I didn't think this part would be so difficult.

Did you have the plastic version of the mightyvac? Mine is made of aluminium, it will break me well before I break it. I need to rebuild mine though, the innards don't last forever.

Can you completely degass a wine using a Mityvac? No whipping needed whatsoever? I might just get one of those instead of the drill mounted one I was looking at.

Yes, I've never whipped my wine. I use the mityvac after ~ every racking, and of course, time.

Is there any thread or something on how exactly that process is done. Like how to connect it and everything?

It's a very simple setup, use the mityvac with the nipple that will fit tightly inside your bung, insert nipple into bung, pump mityvac till exhausted. A fresh wine will begin to release trapped gas within a few squeezes of the handle, and continue for a while. I consider a wine to be degassed when I can get a relative vacuum of 25 PSI on the guage for a little while. It takes some time, but it will get there.
