I saw a posting for a liquid to put in air locks to reduce evaporation
but for the life of me I cannot remember what it was, could anyone
help me out. I have been using a potassium metabisulphite and water
solution but it seams to evaporate quickly.

Jim,
Some add glycerin to inhibit evaporation.HTH

John is that straight glycerin or a blend of glycerin and water and if
so how much half and half?

Jim,
I have seen it suggested to use it 1:1 with sulphited water, and also I
have seen some use glycerin undiluted. Just make sure it is food grade. HTH

Glycerin is not only not able to evaporate at room temps, but it is also
hygroscopic, means it soaks up water from the air.

I must confess that I never have used glycerine as an additive to my
fermentation locks. I always ensure that the solution of Sodium/potassium
Metabisulphite occupies a good measure of the available "u bend". I always
cap my locks with a suitable cap which seems to prevent major evaporation
loss. Clearly there is virtually no activity in the wine except for
expansion and contraction of the bulk of the wine and I ensure that the
quantity of solution is such that there will be no "suck back" into my
wine -- just air in extreme circumstances -- but then the head space above
my wine is minimal..
I should be more worried about suck back of a glycerine solution than of SO2
solution

Glycerine is a perfectly normal natural chemical and is even added to
many wines to give them body and sweetness. Don't worry, be happy!

Bob, Cant say for fact, but I am relatively sure that there is more than one
form of Glycerin as I have seen it specifically stated to acquire "food
grade". HTH

I think glycerin is glycerin. It's a chemical compound (I can't quote
the atomic composition). I think the reason to use "food grade"
glycerin is that you want to assure that any impurities in the product
won't be hazardous to human health. Many chemicals come in lower
quality grades for industrial purposes - the purest ones are used for
pharmaceuticals and in food processing. You should be able to find
"food grade" glycerin at most drug stores (look for the initials USP
somewhere on the label).

Oh I am not concerned about the glycerine "tainting" the wine --I just
wouldn't want it to affect the body of the wine that I have gone to great
lengths to be crisp and dry. I do use glycerine as a additive to my homemade
liqueurs to improve the "mouth feel" but I use sugar to adjust the sweetness
in them.

Glycerin can be a by-product of beef fat IIRC, but most glycerin is
vegetable glycerin. I have no idea what plant it would come from, and my
books all seem to imply that it is only from animal fats. <sigh> So much for
my remembery....
