I thought I'd throw down a little plug for these guys because I think their product is really neat! I haven't been able to try them as of yet but think it's a brilliant concept. Their "Tulip" goblet is a 187.5ml single serving of wine. All you have to do it peel back the seal and your ready to drink! These strike me as an amazing tool for a picnic or pool adventure!!
The company is out of London and you can check out their website here: Wine Innovations
I'm not sure about the availability of the product here in the US but I hope they will be a widely distributed product in the near future. The only thing that I would be interested in finding out is the average shelf life of the glass and if the seal is strong enough to protect the wine.
