Looking at what everyone else is getting from it, I think it's an automatic soda fountain - mixes the flavors in on its own, I mean, you still have to press buttons to make it work.

[There is a short pause as it hits him that he's talking to Fifteenth Century Guy about this.]

So, basically it's fizzy water that tastes like fruit, or just sweet. Like some French wines, or ciders, but it won't get you drunk. I don't recognize any of the flavors here, though....
