Degassing Idea..........

[btom2004]

@btom2004 do you have a pic of your setup? maybe because it's late, I am not completely grasping your concept.

This is the hook up to rack and degas wine under vacuum pressure. You can see how I used tubbing and carboy cover. The wine never touches the overflow side of the hook up or the vacuum pump. Once the air is sucked out the over flow 1 gal carboy, it then sucks the air out of carboy #2. This in turn draws the wine out of carboy #1 and drops it into carboy #2. This is done with out any air touching the wine. Make sure when you use racking cane, to keep it below the surface of the wine being tranfered.

I then Placed the same hand held vacuum pump onto the carboy cover and capped it with my wine saver release valve. This way I can release pressure while degassing further. Place this on top of your 5-6gal carboy and pump gas out of wine.
Note: The above photo was just a test to see if hook up would work. Only use glass carboys when racking and degassing with the above set up #1 and #2.

I give you alot of credit in order to try and make this work, If I may give you some suggestions? And please don’t take it the wrong way – because I had to learn the hard way.

How many inches of vacuum are you pulling while doing a transfer?

How long does a 6 gallon transfer take?

Typically a plastic better bottle will start to implode between 2-4 inches if vacuum , with that said - it would be nearly impossible to have enough negative pressure in order not to have contact with air. Typically when using a vacuum unit , you have a lot more vacuum (usually around 17-22 in hg ) which is pulling the CO2 and filling any of the empty headspace with CO2 to protect the wine from oxygen.

Second – the inline vacuum T at your reservoir is not protecting your pump from getting liquid in it as well, what you need is a double hole bung in order to do that. I noticed that your universal carboy cap should also have a racking cane going down the middle in order to stop the liquid being transferred going directly over to the vacuum side, which could ruin your pump.

Steve, Is there no effective way to degas using a vacuum if you use plastic carboys?

Then again, why be in such a hurry. Fruit wines degass themselves over a few weeks and I find that my grape concentrates are completely degassed after 3 stirrings of 100 within a week. After that I stabilize and add bentonite.

The only way I know is to transfer into a glass carboy using a vacuum pump, (Typically above the plastic carboy) then you are able to gravity siphon back into the the plastic carboy - without ever having to lift any full carboys.
I hope this helps

How many inches of vacuum are you pulling while doing a transfer? Not sure? The pump does not register any pressure. It just pulls the air out and starts the transfer.

How long does a 6 gallon transfer take?About 15 minutes

I use glass carboys only for wine making.

There was never any danger of any spill over reaching that area of the hook up. The full amount from the 1st carboy is never going to be more than that of the 2nd. There will be no spill over at all here, as one would not be racking all of the lees ect. Although a double hole bung would work.

This was just a quick hook up and it worked fine. Although I can see the minus vacuum effect on that second plastic carboy now that you mentioned it. I didn't even attempt to use the degassing rig on them. Thanks for your imput on how to make it better.

I'll have to make a better one one day. That was my first attempt.
