Coca-cola Zero Recipe

Prepare chilled carbonated water

Begin with 2 cups of well-chilled carbonated water. Use soda water from a reliable carbonator or very cold bottled sparkling water. Keep it chilled and do not vigorously stir to avoid losing carbonation.

Add color and acidity

Carefully add 1 teaspoon of caramel color syrup to the carbonated water. Then add 1 teaspoon of diluted phosphoric acid solution to introduce the signature tart acidity. Gently swirl the glass or container to incorporate without causing excessive fizz.

Add cola flavor and caffeine

Add 1 teaspoon of natural cola flavor concentrate and the measured 50 mg of food-grade caffeine to the mixture. Stir very gently to combine; avoid vigorous mixing to preserve bubbles.

Dissolve sweeteners

Measure 100 mg aspartame and 50 mg Ace-K. If using powdered forms, dissolve them in a tablespoon (15 ml) of room-temperature filtered water first to ensure even distribution. For liquid preparations, add directly but ensure accurate dosing. Stir until fully dissolved.

Combine sweetener with syrup base: Slowly add the dissolved sweetener solution to the carbonated syrup base while gently stirring or swirling. Taste carefully; small changes in high-intensity sweeteners have a large effect. Adjust by tiny increments (5–10 mg) if needed for desired sweetness while keeping total within safe limits.

Chill and serve

If desired, add 1 cup of ice to a serving glass. Pour the prepared Coca-Cola Zero over ice gently. Optionally garnish with a lime or lemon wedge on the rim. Serve immediately to retain carbonation.

Storage note: This preparation is intended for immediate consumption. If you must store, keep chilled and sealed; carbonation and flavor will degrade over a few hours. Do not store long term.
