For about 6 months I've been telling myself I'll get that Mityvac hand pump out and rig something up.

OMG ... I put a little vacuum on a jug of strawberry I thought was already degassed and the co2 started popping out all over the place! :)

Funny - It starting getting clearer right before my eyes.

I'll never waste my time beating the snot out of my wine with a paddle ever again. PLUS, I'm not risking stirring o2 in either.

Somebody said something about equipment for 2010. Me? Vacuum. Vacuum degas and transfer is where I'm headed! No more beatup wine or pumping syphons for me!!

I'm gonna' put that carboy right where I want it BEFORE it's full :)
 
Can others weigh in on this method? Very interested to know if it's as good as it sounds.
 
mike. there is lots of info on vacuum degassing here. and some recent discussion on equipment.
many start out with mity-vacs or wine-saver hand-pumps.
i and a few others went straight for commercial vacuum aspirators like those used in the medical/dental industry, Gomco is a popular brand. they're often inexpensive on ebay, they typically can pull 22Hg without protesting, they are quiet and most are 100% duty cycle oilless designs.

with an elec vacuum pump you can rack, filter, bottle and degass. so it makes for a very versatile investment.

technique i use for degassing is to ensure wine is at proper temp 75*-85*, glass carboy is filled up beyond it's shoulders (to minimize risk of implosion) and to pull 17 or so inches of vacuum or until CO2 starts coming out of it's dissolved state. i then close the valve on the vacuum line and shut the machine down and let it hold that vacuum, re-pulling it as foam dissipates and vacuum falls. when it can hold 17" for 30min or more, it's essentially degassed.
 
Very new to vacuum degassing and racking. Still working on the right tubing for racking but the degassing is working great.

If you read awhile back I purchased a Gomco aspirator off of Ebay for 50 bucks. It works great. Get the temp up to 70F or better...and you can enjoy a bottle upstairs while the elec. vac does the work in the basement.

So much nicer than breaking your arm with a stirring paddle.

I use this method and love it no poicking up carbys anymore until they are empty, no more wondering if my wine is degased, and corking a bottle while filling another and doing the whole bottilng and corking 6 gallons in abot 5 minutes pleases me till no end. I just use normal racking hoses to do everything. Heres my set up. You can rack from the floor up also!

Rawlus,

I just learned something new from you. I have a vacuum asperator like yours, but it never occurred to me to close the valve and let it sit until it no longer holds a vacuum. I've always just run the pump continuously and I'm never quite sure when the CO2 has ended and it's O2 boiling off.

Im not sure all models will hold a vac like mine can cause I tried telling a friend about this method and either his doesnt do it or he was just being an idiot that day which is quite possible. He never seems to understand anything I say until show him! Maybe its just me not knowing how to communicate? Maybe I dont speaka English!
 
I find is a vacuum splash rack out of the secondary (around day 35), degassing is not an issue. It is all gone.
 
Just got my rig up and running. Did a quick degass test, and it works like a charm! bought a gomco 300 on ebay for 50, added some home depot parts, and i'm good to go!

special thanks to rawlus for helping me out!!
 
I use the drill mounted mix stir for mixing and degasing. Can't use a pump on a better bottle and only have one glass carboy at the moment.

you worried about scratching the inside of the better bottle w/the fizz-x or other drill mounted fixture?

scratches to bacteriums to vinegar
 
I'm not too worried. I keep the paddles away from the sides. It's not perfect but works. I gotta get more glass carboys.
 
I'm thinking about getting one of these, I'm concerned we are not getting all the CO2 out of our wine =(
 
What exactly is this mityvac hand pump. Doing a search only turns up a vaccum pump for automotive. How are you working it with the carboy? Single hole stopper and tubing?
 
I found some aspirator pumps on ebay new for $100 with free shipping. Tempting......

Looks good to me and that is the brand used by a friend on this forum who has a pretty decent sized vineyard and uses it all the time for filtering, bottling, and racking and Im not just talking about 6 gallon batches.

As far as the Mityvac, goes, that works well also and that is what I had until I bought the electric pump to save my back so I wouldnt have to pick up 6 galon carboys off the floor anymore.
