Coca-Cola Zero contains artificial sweeteners (aspartame, acesulfame K, sodium cyclamate), synthetic caramel coloring E-150d, and phosphoric acid. This clean organic version eliminates all artificial ingredients, using natural stevia, organic spice extracts for cola flavor, and coconut sugar caramel for coloring. No seed oils were present in the original product.

Why This Recipe is Seed Oil Free
Commercial Coca-Cola Zero from Coca Cola often contains inflammatory seed oils like canola, soybean, or sunflower oil. This homemade version replaces them with healthier fats like butter, ghee, coconut oil, or avocado oil — giving you the same great taste without the processed oils.
The original Coca-Cola Zero may also contain artificial dyes. Check it on DyeFreeCheck to find out.

Instructions
Step 1. Create natural caramel coloring by heating 30g (2 tablespoons) organic coconut sugar in a heavy-bottomed saucepan over medium heat for 8-12 minutes, stirring constantly with a wooden spoon until it melts and turns deep amber. The sugar will foam and smell nutty when properly caramelized. Remove from heat and immediately whisk in 60ml (1/4 cup) hot filtered water - it will sputter vigorously. Stir until smooth caramel syrup forms. This provides natural brown coloring without synthetic chemicals and adds subtle molasses notes that enhance cola flavor complexity.
Step 2. Prepare the cola concentrate by combining the caramel syrup with 15ml (1 tablespoon) organic vanilla extract, 2g (1/2 teaspoon) organic cinnamon powder, and 2g (1/2 teaspoon) Redmond Real Salt in a large mixing bowl. Whisk vigorously for 3-4 minutes to ensure even distribution - the cinnamon tends to clump if not properly incorporated. The salt balances sweetness and enhances flavor perception while matching the original's sodium content.
Step 3. Add essential oils drop by drop while whisking continuously: 10 drops organic orange oil and 6 drops organic lemon oil. Essential oils are extremely potent - more than this will create an overpowering soapy taste. Whisk for another 2 minutes to ensure oils are fully emulsified into the base. The citrus oils provide the bright top notes that define cola's characteristic flavor profile.
Step 4. Dissolve 8g (2 teaspoons) organic citric acid in 500ml (2 cups) room temperature filtered water, stirring until completely clear - this takes about 3-4 minutes of constant stirring. Citric acid replaces harsh phosphoric acid while providing the necessary tartness that balances sweetness and enhances carbonation perception. Add this acidulated water to the concentrate and mix thoroughly.
Step 5. Prepare sweetener solution by dissolving 3g (1 teaspoon) organic stevia extract powder in 200ml (3/4 cup) warm filtered water. Stevia requires thorough dissolution to prevent bitter aftertaste - whisk vigorously for 5 minutes until no granules remain visible. Let cool to room temperature before adding to prevent essential oil evaporation. This natural sweetener provides intense sweetness without calories or blood sugar impact.
Step 6. Carefully measure 0.5g (about 1/4 teaspoon) natural caffeine powder using a precise digital scale - caffeine is potent and overdose is dangerous. Dissolve in 100ml (scant 1/2 cup) warm water, stirring until completely clear. This provides approximately 34mg caffeine per 330ml serving, matching typical cola levels. Cool completely before combining with other ingredients.
Step 7. Combine all prepared components in a large pitcher and add remaining filtered water to reach exactly 5 liters total volume. Stir gently but thoroughly for 3-4 minutes. Taste and adjust: add more stevia solution if sweeter flavor desired, or more citric acid for increased tartness. The concentrate can be stored refrigerated for up to 2 weeks.
Step 8. Carbonate using a SodaStream or similar system: fill bottles with cola concentrate leaving 2 inches headspace, carbonate to desired level (typically 3-4 pumps for cola-like fizz), and chill thoroughly before serving. Each 330ml serving provides 1-2 calories from natural ingredients, 26mg sodium, and 34mg caffeine. Store carbonated bottles refrigerated and consume within 5 days for best flavor and carbonation retention.
Storage
Store concentrate refrigerated for up to 2 weeks. Carbonate only what you'll consume within 5 days as natural ingredients don't preserve as long as commercial versions. Keep carbonated bottles tightly sealed and chilled to maintain fizz.
