Coca Cola recipe
Recipe 1
This recipe is attributed to a sheet of paper found in an old formulary book owned by Coca-Cola
inventor, John S. Pemberton, just before his death (U.S. measures):
Ingredients:
1 oz caffeine citrate
3 oz citric acid
1 fl oz extract vanilla
1 qt lime juice
2½ oz flavoring
30 lb (14 kg) sugar
4 fl oz fluid extract of coca (decocainized flavor essence of the coca leaf)
2½ gal water
Caramel sufficient
Flavoring:
80 Oil orange
40 Oil cinnamon
120 Oil lemon
20 Oil coriander
40 Oil nutmeg
40 Oil neroli
1 qt
alcohol
This recipe is from Food Flavorings: Composition, Manufacture and Use (2nd Ed.) 1968 by Joseph Merory (AVI Publishing Company, Inc., Westport, CT). Makes one U.S. gallon (3.8 L) of syrup. Yield (used to flavor carbonated water at 1 fl oz per bottle): 128 bottles, 6.5 fl oz (192 ml).
Mix 2,400 grams of sugar with just enough water to dissolve (high-fructose corn syrup may be substituted for half the sugar).
Add 37 grams of caramel, 3.1 grams of caffeine, and 11 grams of phosphoric acid.
Extract the cocaine from 1.1 grams of coca leaf (Truxillo growth of coca preferred) with toluol;dry the cocaine extract.
Soak the coca leaves and kola nuts (both finely powdered; 0.37 gram of kola nuts) in 22 grams of 20 percent
alcohol.
California white wine fortified to 20 percent strength was used as the soaking solution circa 1909, but Coca-Cola may have switched to a simple water/alcohol mixture.
After soaking, discard the coca and kola and add the liquid to the syrup.
Add 30 grams of lime juice (a former ingredient, evidently, that Coca-Cola now denies) or a substitute such as a water solution of citric acid and sodium citrate at lime-juice strength.
Mix together 0.88 gram of lemon oil, 0.47 gram of orange oil, 0.20 gram of cassia (Chinese cinnamon) oil. 0.07 gram of nutmeg oil, and, if desired, traces of coriander, lavender, and neroli oils, and add to 4.9 grams of
95 percent alcohol.
Shake.
Add 2.7 grams of water to the
alcohol/oil mixture and let stand for twenty-four hours at about 60 °F (15.5 °C). A cloudy layer will separate.
Take off the clear part of the liquid only and add the syrup.
Add 19 grams of glycerine (from vegetable source, not hog fat, so the drink can be sold to Jews and Muslims who observe their respective religion's dietary restrictions) and 1.5 grams of vanilla extract.
Add water (treated with chlorine) to make 1 gallon of syrup.
