100% lemon juice made with real lemons. Tastes great, and just like youd expect it to be! Which in my opinion is just like the real thing but without the mess. The only time I buy actual lemons is if I need the zest for something, or if I plan to make fresh brewed iced tea. Other than that, I buy it by the bottle because when I put lemon juice in a fruit smoothie, youd never be able to discern whether or not it was fresh or bottled lemon anyway. Or at least my taste buds cant!
