When we were here before, we discovered the most unique wine store – at least to us.
It is very simple.
You purchase an empty 1-liter bottle (or bring your own).
You choose from a wide selection of kegged wines, and the storekeeper “pumps” the wine into your bottle, like beer. (I do not know the proper terminology for this.)
It is very economical, too. We got a liter of Cabernet Franc for 3 Euro 60 – including the plastic jug.
Next time we go back, it will even be cheaper since we’ll bring our own bottle back! We may even splurge for Prosecco!
P.S. If you are looking for this store, it is near Campo SS Giovanni e Paolo – across from a Coop market. On Google Maps, it is simply listed as “Wine Shop Across from Coop.” : )
