Real lemons. Tart not sweet. Lemons are tart. So a sparkling lemon should be tart. Growing up, I visited my grandma every winter. She had a lemon tree in her yard. And my absolute favorite thing to do was pick the lemons and then drink the juice straight. So I wanted Q Lemon to taste like it comes from Grandma Jana's tree. Tart, not sweet. I started with real lemons, lots of them. And then added just a dash of organic cane sugar and some carbonation. So Q Lemon is tart and crisp, yet completely refreshing. And makes me think of Grandma Jana. Enjoy, Jordan Silbert, Founder. Q Lemon (per 12 oz): 70 calories; 18 g organic cane sugar sweetener. Sprite (per 12 oz): 140 calories; 38 g high fructose corn syrup sweetener. San Pellegrino Limonata (per 12 oz): 160 calories; 36 g sugar sweetener. One lemon is a full day's supply of vitamin C. But that's the whole fruit - the juice only holds about a third. Better start eating rinds. Learn more at qdrinks.com. Brooklyn, NY.
