Grams & Liters opened with one simple, slightly rebellious idea — ditch the juice-bar script and start fresh. Bright-cut fruits lined up like a palette, jars of nuts and seeds winked from the counter, and customers stepped up to toss in whatever caught their eye.

Of course, handing that kind of power to just anyone? Risky business. One rogue kiwi can crash a whole flavor party if no one catches the sour twist before the blade spins. So the team mapped flavors, ran messy midnight taste-tests, and landed on color-coded tags that quietly say “earthy,” “zesty,” or “creamy” letting customers play, without wrecking the recipe.
