I tried dealcoholized wine before, it still has a tad bit of alcohol in it, like .5%. It's pretty good, but I'd say alcoholized wine does taste better. If you wanna dealcoholize wine, you can just boil it. I think the reason the dealcoholized wine tastes worse is because it's probably dealcoholized by boiling, so yeah. Probably for thirst, what you'd wanna do is, get the dealcoholized wine and then water it down, I do that with grape juice.
The other thing you gotta keep in mind with wine is, it all tastes different by types and brands, zinfadel will taste different than a straight out red wine, white wine will taste different, champagne, etc.
But, if I didn't have to be paranoid about DUIs, I'd probably drink alcoholized wine like the old days, just as a barely alcoholized beverage. That or drink kvass or kinderbeer kinda stuff.
If you like dealcoholized wine, you might like the random Malta drinks in the Spanish section of the grocery store, basically a really dark sugary non alcoholic beer. But they're like 300+ calories per 12oz bottle, though.
