There are lots of ways of doing this, some work, some don't very
Refridgeration only makes the yeast go dorment. They will start up
again if they can get above a certain temperature. Matter of fact, some
yeasts want to ferment at colder temps. They take much longer though.
I believe in once refridgerated, always refridgerated.
Adding a stabalizing agent. I've not had much luck this way. Some info
from the wine.faq is:
Sorbate: Potassium sorbate. A substance that is noxious to yeasts
and as such is used as a stabilizer. It should be noted that sorbate's
effectiveness depends on low yeast counts in the wine; if it's high, it
will be inneffective. Clear your wine properly, and ferment out to sg
1.000 or less.
Sulphite (or sulphate): Referring to sodium metabisulphite or potassium
metabisulphite. A substance that is noxious to many spoilage
microorganisms and wild yeasts and as such is used as a microbiological
and oxidative inhibitor and stabilizer. It should be noted that
sulphite's effectiveness depends on low organism counts in the wine; if
it's high, it will be inneffective. Clear your wine properly and
ferment out to sg 1.000 or less.
Pasteurization is done by steeping in a water bath at 60 C (140 F),
and hold this temperature for 20 mins. Cool to 18 C (74 F). I've never
tried this. I've heard lots of people have bottles explode doing this.
I believe in either using a yeast that will stop at the desired
sweetness, usually ale yeasts work well and the one I use stops at
about 10% alcohol, or starting with a higher opening SG. Champagne
and wine yeasts go from 8 to 18% depending on the strain. Letting
fermentation go to it's full extent will also leave a clearer wine in
the end. (Less dregs at the bottom.)
Btw, although clearing agents help some, a single yeast cell can start
it all off again.
