I just finished this bottle off... I'd opened it for a family friend who visited as he was not boozing.
It "looks" very good... looks a lot like wine
Tastes pleasant.. (however doesn't taste like wine)
so worthwhile keeping a bottle or 2 in I think... psychologically useful if you fancy a glass, but shouldn't really.
If you are thirsty and have a fair bit in the glass, you can glug it down (it's grape juice more or less) and that is something that doesn't happen with wine. People looking at you will think you are a maniac...
