Perfectly Replicating Coca Cola (It Took Me A Year)

The Coca Cola secret formula is one of the best kept secrets in recent history...and I hate secrets. So, naturally, I deciphered it with the help of mass spectrometry and created a chemically-identical replica! Want to help support LabCoatz? Of course you do!

CURRENT RECIPE: same as video, but use 10 grams of tannin, 150 grams of glycerin, and 43mL of 85% phosphoric acid. And if you use Durkee caramel color (since Shanks no longer seems to be available), use 185mL instead of 320mL, since it's much stronger. New warning regarding tea tree oil: it's not FDA-approved, so use at your own risk. Looking for an alternative. PER LITER OF SODA (VERSION 111C): 104 grams sugar (dissolved in a minimum volume of water) 1mL flavor solution A (alcohol-based) 10mL flavor solution B (water-based) Top off to 1 liter with cold carbonated water FLAVOR SOLUTION A: dilute 20mL of the following oil mixture to a volume of 1 liter using food-grade 95% alcohol. 45.8mL lemon oil 36.5mL lime oil 8mL tea tree oil (from Australian tea tree, Melaleuca Alternifolia) 4.5mL cassia cinnamon oil 2.7mL nutmeg oil 1.2mL orange oil (regular sweet orange) 0.7mL coriander oil 0.6mL fenchol (any version of alpha-fenchol should work) *UPDATE: it has been brought to my attention that tea tree oil is not FDA-approved for food/beverage use. The amounts used appear to present no more risk than Coca Cola itself, but I am working on finding a safer substitute! If you want to play it safe, leave the tea tree oil out for now. FLAVOR SOLUTION B: dilute the following mixture to a volume of 1 liter using water. 185mL Durkee caramel color 150 grams food-grade vegetable glycerin 43mL 85% phosphoric acid 10 grams wine tannin 9.65 grams caffeine 10mL 5% vinegar 10mL vanilla extract (or a solution containing 0.95 grams per liter of vanillin) If you like glass bottle "Mexican" Coke, just increase the lime in the final mix. I haven't actually made an effort to replicate glass bottle Coca Cola, but that seems to be basically the only difference. Here's the research paper I referenced throughout this project: https://pubs.acs.org/doi/pdf/10.1021/... Regarding the types of essential oils to use, there is not a standard for "food grade" essential oils...as long as the sample is verifiably pure, that's as good as it gets. Brands like NOW and Aura Cacia seem to be reasonable. For the fenchol, different CAS numbers should be suitable as long as the sample is over 90% alpha-fenchol. There are no substitutes for fenchol, and despite what Wikipedia says, basil does not contain a significant amount of it...based on my research, it might have some fenchone or fenchyl acetate, but that's it, and these are minor components. Fenchol has a very distinct, heavily musty, earthy, or moldy smell, with some camphor or mint-like notes in high doses. WARNING: concentrated phosphoric acid is mildly corrosive and undiluted flavors and essential oils can be irritating or toxic. Never consume, unless properly mixed and diluted to safe levels. Tea tree oil is not GRAS (generally recognized as safe to eat), although the few microliters added to this cola shouldn't cause health issues due to the low dosage and similarity to the chemical makeup of other sodas. You will honestly absorb less of it by drinking this soda than you would by using a tea tree lotion or mouth wash! 0:00 Secrets secrets secrets 1:18 A fool's errand...or not? 2:56 What's in Coke? 3:29 Coca (but not cola) 4:10 Flavor basics and early trials 7:17 Mass spectrometry (thanks Vince and Ben!) 9:12 Research papers and key discoveries 11:54 Spreadsheet time 12:20 The missing flavors 13:44 A year of testing 14:23 A BIG discovery...we nailed it 15:27 How to make Coca Cola 17:16 Mixture A: 7X flavor 18:47 Mixture B: water-based ingredients 19:46 Mixing up the cola 21:41 What do other people think? 23:27 Looking forward
