Metromint water is a great new addition to my fridge. Created by the husband and wife team of Rio Miura and Scott Lowe (who are also behind David Rio teas), Metromint is made with only two ingredients: pure water, and mint from Washington. The flavor is just right-- a notch or two above subtle, and way below intense. I've been bringing it to the gym and enjoying it in the afternoons when a mint julep isn't an option. It's really refreshing and a nice change of pace from fruit or sweetened waters and tea. You can find it at Whole Foods and other retailers for around $1.50 a bottle.
