Vacuume question

[Montresor]

So I am going to degas with a break bleeder, but I have read that you should use under 20 inches of mercury or the alcohol will boil out. Then I read 29" or gas will not be released. Could someone please clear up the confusion and how long to keep it on to degas.

Hit it at 22 or 23. I'd not go to 29. To me that's too much.

 

[Montresor]

Thanks 29 sounded a bit high to me to

I agree, Dr is spot on.

I can easily get over 20 but I have never tried to get more than that.i assume it takes a arm numbing amount of work to get it to 26/28 inches. Is that really necessary or can you just keep it at about 20 for a good while?

I dont think you have to worry about boiling your wine with a hand vacuum unit. The reason I say that is the temperature of the wine and every time CO2 is released your vacuum pressure will drop, so you would have to continue to pump for excessive amount of time. I agree with dralarms that 22-23 should be more than adequate
