It’s always been common knowledge among maple syrup producers that taking a sip of sap was a good way to quench their thirst while working in the sugarbush, but apparently the notion that it could be a marketable substance is a new one. The first impression after downing a glass of maple water is that it tastes like water, but with a slightly sweet aftertaste and a tiny hint of earthy, maple syrup-like flavor.With coco water (and other flavored waters) selling for $4 a pop, it’s a wonder that no one thought of bottling maple water sooner. It’s all-natural, sustainably-produced, vegan, gluten-free, non-GMO, paleo and local (it’s especially local if you live in a maple syrup-producing region, but it’s more local than coco water no matter where you are in the U.S.).
