VINEBOX (YC W16) Lets You Try New Premium Wines, by the Glass

It's interesting to see YC investing in a subscription-based food/drink business years after that wave has peaked in popularity. It would seem there must be something special that I'm overlooking here.

Perhaps technology involved in the glass tubes or IP related to single servings of wine. Maybe it's just the relationships and the idea of cutting out middleman from vineyard to glass.
