While I'm no great wine drinker, I'm glad that this "technology" has finally reached New Jersey! (Sorry, Bucky, couldn't resist!)
A quick class on wine...the "juice" that comes from a grape is fermented into "wine"...
Grant you all that the "juice" that comes from rhubarb, blueberries, crabapples, beets, dandelions (the list is endless!) may also be "translated" to "wine", but lets just pay attention to the "purists" that say it "has to be grape"...
The "juice" that is fermented from the grapes is "different" by its sugar content, which is why "Chablis" is pretty "dry" and "Ice Wine" is VERY sweet...
When the Chablis grapes are harvested, the grapes are literally "bulging" with moisture (ie "juice"), but are relatively low in "sugars" on a volume basis...and so the wine gets to taste relatively "dry"...
If you look at German wines, you get the "Auslese", "Spatlese", etc (gradients of "perfection"-and fairly "cheap" and "accurate" means of buying the "good stuff")(Germany has a strict control for wines that the French lack!)
Anyways, as the grapes hang on the vine, the individual grapes "dry up" and lose the volume of water, which "concentrates the 'nectar' within" while not reducing the sugars...that makes for a more "intense" flavour, as well as a "sweeter" wine product...
The Germans created "Ice Wine" (Eizwein") by watching their grapes being frozen by "bad" weather", and picking the "ruined" frozen grapes, and crushing same to try to "salvage the crop"...
Amazingly, crushing them in the frozen state caused the water to turn to ice, which splinters off fairly easily, leaving the semi-liquid "nectar" (juice and sugar) to the fermentation process...in fact, you get about 1/7th the "volume" of liquid to work with...(which starts to account for the incredible price increase!)
This "sugary" nectar parlays into some fantastic product...in fact the Germans can only "gamble" that weather will favour them with the right conditions (you have to "harvest" the grapes at about minus 5 F, and there's no "mistaking" on this point!)...in Germany, its a bit of a "fluke" to get such a harvest...in California, its "impossible", in Ohio its terribly risky...in Ontario, its nearly a "certainty", and our grape growers are winning International Awards to beat the band with ice wines (aside from the fact that we produce some really great whites!)(and, if you can find them, good to "great" "old growth" reds!)
Am happily in the exact region that does the "Ice Wine" thing, and our inters are MOST ANXIOUS that people outside of Canada get to "sample" the product...it comes in "splits" of about 12-15 ounces (chill thoroughly before drinking!) and, locally, costs about $30-50 (Cdn$) a bottle...
Note that if we can ship it out of country, the Vinters will drop the price slightly, to attract new buyers and markets (or at least this was the case a few years ago!)...anyone interested in a very "unique" dessert wine taste experience can PM me, and I will hook you up to the Vinters involved...please do NOT ask for instantaeneous transfer...I'll have to call around and find who has what to sell, but will get it done, nonetheless...
