This is the same sort of device we've seen recently. I was coming here to post it, but was beaten to the punch.
So this seems to be a nicer version of boxed wine (some of which isn't bad.) But you're stuck working with one supplier for the wines and their pricing and quality.
However I do think this is going to be seeing more like this as we go. Maybe what needs to happen is common connectors to encourage more wineries to put some of their wines into it.
