That's difficult to say, a few days at least. I leave mine at 25 F for a few weeks. Is the wine very clear: IE if you shine a flashlight through it do you see particles in suspension in the beam? If so, you may want to consider renting a filter; I'm just not sure the ice trick will work well enough. You can get one a wine shop pretty cheap, I have a Buon Vino Mini-jet and the sterile filter gets wine pretty clean. It's not a true sterile filter, but it will do a pretty good job.
In the future when you make a dry wine the following is the procedure to measure dryness with clinitest tablets; most pharmacies don't stock them but can get them. (Any pharmacy supplied by McKesson can get them, we stock them.) These tablets can be used to determine if there is any residual sugar left in your wine.
OT Synthetic Whiskeythere are 3 phases to a alcohol distillation, the first part, called the heads (some people further divide this up into two more categories, but...
What you do is: For sweet wines, follow the instructions.
For dry: * Ignore the instructions that came with it: * Place 10 drops of wine in the test tube: * Using the '2 drop' chart determine RS by matching the color change and dividing the result by 5.
They sell a test kit which include the test tube, eye dropper and a small bottle of tablets, they also sell bottles of 100 and foil packs of 100. I can only get the 100 tab bottle now, it's a Bayer product, PN 2126.
Hope that helps, Joe If the RS is 0.2% or less the wine is dry
