Coca-Cola delivers 140 calories from 39g of high-fructose corn syrup per 12oz, plus artificial caramel color, phosphoric acid, and undisclosed 'natural flavors' likely containing synthetic compounds. This DIY version uses organic cane sugar, real vanilla and citrus oils, blackstrap molasses for natural color, and citric acid for a cleaner ingredient profile with identical nutritional impact.
Based on: Coca-Cola Classic
· Makes approximately 40 servings (40 oz concentrate)
· Serving: 1 oz concentrate + 11 oz sparkling water (equals 12 fl oz)
Why This Recipe is Seed Oil Free
Commercial Coca-Cola Classic 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.
Provides natural caramel color and slight mineral complexity, replacing artificial caramel color

Instructions
Step 1. Create the sugar syrup base: In a heavy-bottomed saucepan, combine 480ml (2 cups) filtered water with 1560g (7.5 cups) organic cane sugar. Heat over medium heat, stirring constantly with a wooden spoon for 8-10 minutes until sugar completely dissolves and mixture reaches a gentle simmer. The syrup should be clear and thick enough to coat the spoon. Remove from heat and let cool for 15 minutes - this prevents the essential oils from evaporating when added.
Step 2. Prepare the spice blend: In a small bowl, whisk together 2g (1 teaspoon) Ceylon cinnamon and 0.5g (1/4 teaspoon) nutmeg until evenly combined. Add 8g (2 teaspoons) citric acid and whisk again. This dry mixing ensures no clumping when added to the syrup.
Step 3. Create the flavor base: To the cooled syrup, add 24ml (1.5 tablespoons) vanilla extract and 15ml (1 tablespoon) blackstrap molasses. Whisk vigorously for 2 minutes until molasses is fully incorporated and no streaks remain. The mixture should be dark amber colored.
Step 4. Add citrus oils carefully: Essential oils are potent and must be properly emulsified. Add 12 drops lime essential oil and 8 drops orange essential oil directly to the syrup, then whisk continuously for 3-4 minutes. The oils may initially float on top - keep whisking until fully incorporated and the mixture appears uniform.
Step 5. Incorporate dry ingredients: Add the spice and citric acid blend to the syrup. Whisk thoroughly for 5 minutes, ensuring no powder pockets remain. The mixture may foam slightly due to the citric acid reaction - this is normal. Strain through a fine-mesh sieve to remove any undissolved particles.
Step 6. Add caffeine source: Sprinkle 2g (1/2 teaspoon) green tea extract powder over the surface of the syrup. Whisk continuously for 3-4 minutes until completely dissolved. The powder may clump initially - break up any clumps with the whisk and continue mixing until smooth.
Step 7. Final mixing and straining: Whisk the entire mixture vigorously for 2 minutes to ensure all ingredients are fully combined. Strain through a fine-mesh sieve lined with cheesecloth into sterilized glass bottles. This removes any remaining particles and ensures a smooth final product. The concentrate should be dark brown and aromatic.
Step 8. To serve: Mix 1 oz (30ml) concentrate with 11 oz (325ml) chilled sparkling water in a 12 oz glass filled with ice. Stir gently to avoid losing carbonation. Taste and adjust - some prefer a stronger flavor (1.25 oz concentrate) or lighter (0.75 oz concentrate). Store concentrate refrigerated for up to 6 weeks in sterilized glass bottles with tight-fitting lids.
Storage
Store concentrate in sterilized glass bottles in refrigerator for up to 6 weeks. Natural separation may occur - shake gently before each use. Unlike commercial cola with preservatives, this version will gradually lose potency over time. For best flavor, use within 4 weeks. Never store in plastic containers as essential oils can break down plastic over time.
