Deconstructing the
Original Brew
A data-driven interactive guide to John Pemberton's 1886 notebook. Explore the precise chemistry, the "Merchandise 7X" secret blend, and the brewing process that launched the world's most famous beverage.
The "Merchandise 7X"
This is the holy grail of soda history. The "7X" is a highly concentrated flavor emulsion. While the carrier is alcohol (236ml), the flavor comes from a precise blend of essential oils.
The Secret: Emulsion
The oils are mixed with high-proof food-grade alcohol and left to stand for 24 hours. This creates a clouding effect, historically normal, blending the hydrophobic oils into a usable essence.
Safety First
Critical: Must use 100% Food Grade Essential Oils. Aromatherapy oils are toxic.

The Syrup Matrix
The syrup is where the volume lies. It is a massive sugar solution spiced with the 7X concentrate. The chart below uses a logarithmic scale because the amount of sugar is nearly 1000x the amount of flavoring.
Scientific Context: Impact Odorants
Modern analysis reveals the chemical compounds responsible for the distinct "Cola" taste profile.
Neroli & Orange
Role: Top Notes
Provides the fresh, citrusy "pop" that hits the nose first. Bitter Orange Blossom (Neroli) is key to complexity.
Cinnamaldehyde
Source: Cinnamon Oil
The "spicy backend heat." This compound distinguishes true Cola from generic fruit sodas.
Eugenol
Source: Nutmeg Oil
Provides earthy, woody depth. Grounds the sugar and citrus with a savory, darker note.
Vanillin
Source: Vanilla Extract
The "Smoother." It rounds out the sharp edges of the Citric Acid and Lime Juice for a cohesive finish.
Brewing Process
Prepare 7X
Shake oils with alcohol. Wait 24h.
Dissolve Sugar
Heat water & sugar. Don't boil. Add Caramel Color.
Add Acids
Cool slightly. Add Lime, Citric Acid, Caffeine, Vanilla.
The Merge
Add exactly 2.5ml of 7X to the batch. Stir.
The Perfect Pour
Unlike modern ready-to-drink cans, 1886 Cola was a fountain drink. The ratio is critical.
