I was curious as to what a ‘pear’ flavored water would taste, with no sugar. The only ingredients in this stuff are listed as: purified water with pear and other natural flavors. I took a cautious sip and found that I really enjoyed the flavor. The fact that the water isn’t sweet made it more refreshing, but the pear flavor added a little “je ne sais quoi”. The pear flavor is spot-on, too, not artificial at all – just light and refreshing.
