I saw this in the bottled water area at Fresh Farms Niles and was intrigued enough to try a bottle. Had to Google “Greek mastic”and “mastima water”. The beverage has a unique flavor that’s hard to describe. Closest thing I can think of is pine sap. It’s very refreshing. Don’t think it’s for everyone but I liked it so much that I picked-up a case of 12 today. I get 2 servings from one 8oz. bottle.
