I haven't yet found one that doesn't taste like grape juice so interested to hear impressions from others. It's good to see that some are making it onto the shelves in shops now but many are a bit pricey when you know you could be tipping them down the sink. I reckon Dan's should do some non-alcoholic wine tastings! Personally, although it's not a wine, I like the Palermo Rosso with tonic or mineral water - similar to Cinzano - but sadly mail order only, now.
For a low alcohol variety, I then to reach for Lindemans Early Harvest range, at least in the whites. It's not top shelf but quite palatable.
