How to Make Coca Cola

Drink of the Week: Cuba Libre

We are just going to come right out and say it: This week’s DOTW is getting hijacked. Anyone who recognizes the Cuba Libre also knows that it’s just a fancy name for the popular Rum and Coke. Sure, there’s a squeeze of lime, and we’ll get to the drink itself.

Coca Leaf TeaMost of you are probably thinking, “But isn’t the formula for Coke one of the most guarded secrets on earth?” Well, yes and no. Many aspects of the recipe are known (the ingredients are written right on the can), but there is some truth to the story that only a select few individuals know the formula of the primary flavoring component. However, some very convincing evidence exists that the Original Recipe—the one first created by Coca Cola inventor John Pemberton back in 1886—may have been revealed in a newspaper photograph, hiding in plain sight since 1979.

Original Recipe
Sharing the details of this evidence isn’t actually our story. It comes by way of the radio program, This American Life. Back on February 11th, 2011, Ira Glass aired a story in which he describes a photograph of an old pharmacy journal. The photo was published in a Georgia newspaper in 1979 and shows a leather-bound recipe book opened to a page with the title, “Coco-Cola Improved” listing every ingredient, quantity and procedure. It is widely known that back in 1886 when John Pemberton invented Coca Cola in reaction to the temperance movement in Atlanta, Georgia, he sold the recipe to several of his colleagues. This book happened to belong to one such associate and many years later it was re-discovered which led to the newspaper article in 1979.

Percolating

A dusty old recipe journal that belonged to someone nobody remembers would hardly convince most people of the recipe’s authenticity, but Coke historian Mark Pendergrast, author of For God, Country, and Coca-Cola, confirmed that while researching his book in the Coca Cola Company archives, he was allowed to review Pemberton’s notebook. There in the notebook, in Pemberton’s own hand, is the exact same recipe, item-for-item in matching quantities. We would encourage you to check out the radio program yourself to hear how it all unfolds. It’s a fascinating story that includes the help of Jones Soda to whip up a batch along with taste tests and some interesting reactions from flavor experts and regular consumers. You’ll have to draw your own conclusions because the Coca Cola Company will never confirm that this recipe is correct. Nor will they file a lawsuit because doing so would require them to produce the actual formula.
It’s also important to recognize that this is a recipe for the original Coca Cola, not the Coke that is made today. The differences may be subtle, but there is certainly no claim that this is exactly what is sold in stores right now. We know for example that Coke made in the United States no longer uses cane sugar, (although you can buy Mexican Coke that does). We also know that they no longer use fresh lime juice, opting instead for the more stable lime oil. Citric Acid has been replaced with phosphoric acid. You get the idea.

What about the cocaine?
“Coca” isn’t just a playful reference. It’s true that cocaine was part of the original Coke recipe. In fact, the ingredients below include an item called FE Coca, or fluid extract of coca, but by 1903 the cocaine was removed leaving this extract as just another flavor component. Coke still uses it, but the coca leaves used to make the extract have had the cocaine taken out by the Stepan Chemical Company in Maywood, New Jersey. Stepan is the only company in the US that is licensed by the DEA to legally import Peruvian coca leaves. Cocaine-free coca leaves are perfectly legal and available as an herbal tea. Using them to make your own drug-free FE Coca is simple.

Merchandise 7XAnd the Caffeine?
The word cola is a reference to the kola nut, which is a natural source of caffeine. Eventually, caffeine citrate took its place making the nut unnecessary. This is probably one of the “improvements”. We chose to leave out the caffeine which might affect the flavor somewhat. We have read that caffeine imparts some bitterness, but to use the amount specified would result in a beverage five times more potent than what is typically used in soda today! We think we made the right decision to leave it out, but if anyone knows of a proper source for it, we might try another batch reducing the quantity to one-fifth.

Merchandise 7X
That’s the fancy name Coke gives their secret flavoring. Cola is a complex beverage, but the key to building the right combination of natural flavors is to use essential oils. Oil and water don’t mix, and since the majority of the final product is water, you need the oils to emulsify. By mixing tiny amounts of the incredibly potent essential oils with pure alcohol, you stretch the oil drops into a flavoring solution that will more readily mix with the water-based ingredients. We have read that modern soft drinks take advantage of highly specialized emulsifying equipment capable of generating microscopic droplets at practically a molecular level. This results in a mixture that can remain stable in a can or bottle without separating for years. When it was first invented, bottling the product wasn’t a consideration. Like our version here, it was meant to be mixed up and consumed immediately.

Covering with alcoholBasic Syrup
Besides cocaine, the other controversial ingredient in Coke is all of that sugar. The final product has a pound of sugar per gallon of soda. The syrup also contains a fair amount of lime juice. If anything in this recipe took us by surprise it was the amount of lime juice. We had no idea there was so much. There’s also some vanilla and caramel coloring.

So, that’s the basic idea. It doesn’t sound too difficult, right? To make your own, you really have five basic steps:

1. Make FE Coca
2. Make Merchandise 7X
3. Make the basic syrup (using some of your FE Coca)
4. Add some 7X flavoring to your basic syrup
5. Combine the syrup with carbonated water

Actually, you are done with the recipe at step 4. Once you have the syrup, you can make Coke whenever you want by mixing it on the spot. This is similar to how we make ginger beer, so get that siphon ready or grab some club soda. The mixing in step 5 is exactly what happens every time you get Coke from a soda dispenser. You hold your glass under the spout and carbonated water mixes with syrup at a five-to-one ratio. Fascinating!

Making FE Coca
Get yourself some coca tea. We bought ours on Amazon. It arrived in little tea bags, so we had to cut them all open. The next thing we did was reduce the leaf particles in a blender to a powder, but this may not even be necessary. Using a food processor on dry ingredients doesn’t always work, but our coca tea had some pretty big pieces in it, so we figured a finer powder would lead to better extraction. To make the extract, you need a percolator or some vessel that can serve the same purpose. A percolator is a piece of lab equipment that is basically an open cylinder with a screen filter at the bottom where it then constricts like a funnel with a spigot. We don’t have a percolator, but we do have a Clever Coffee Dripper!

Drips of FE CocaFE Coca
1 pound powdered coca leaf
6 oz diluted alcohol (60% abv)
Plus plenty more alcohol to saturate and rinse when straining

You could probably just use a mason jar and filter the result, but the idea is that you need to totally saturate the leaf matter with dilute alcohol and let it sit covered for 48 hours. According to the book A Treatise On Beverages or The Complete Practical Bottler by Charles Herman Sulz, you want to use ethyl alcohol at 60% strength. That’s 120 proof vodka, if you can find it, and if not, figure out the proportions and add water to some Everclear to get you to 60%. According to the book, a proper fluid extract of coca requires a pound of the leaf and 6 ounces of alcohol, plus more alcohol to saturate the leaf matter and even more to rinse when

you strain the results. We’ll admit, there’s some ambiguity here, and since we had about 4 ounces of coca tea, We knew we would probably only end up with some fraction of a cup of extract. This would still be more than enough FE Coca to make so much cola it could rot the teeth of everyone we know.

Once we had a layer of alcohol covering the saturated coca tea, we stretched plastic over the top of the Clever Coffee Dripper and waited two days. In the end, it was the perfect tool to pull this off. We removed the plastic wrap and set the contraption over a glass jar and watched as our FE Coca came out deep olive green. Rinsing the leaves with more alcohol produced even more extract, but at some point we realized we would be diluting the flavor. However, the color continued to be a deep green, and in the end, using 100 coca tea bags, we produced about 6 ounces of finished coca extract.

Making Merchandise 7X with essential oils
Making Merchandise 7X with essential oils

We wondered if we could have saved some trouble and simply left all of that coca in the tea bags. That’s probably the best shortcut if you don’t have a percolator. The extract itself smells like green tea, and the pungent flavor is strong. Not much of this will go into the syrup, and before we started we wondered if it would be worth the effort or expense. But, after making the extract, it really wasn’t that hard after all, and when it came time to mix everything together, we were surprised how much aroma carried into the syrup from the tiny amount used.

Making 7X (the secret formula)
This part requires Everclear at full-strength. You really should have the 95% (190 proof) stuff. The 151 might work too, but we think it’s expected that you are mixing your essential oils with pure alcohol. Although it can be a challenge getting all of the essential oils (and they tend to be somewhat pricey), this was probably the easiest part of the whole operation. It’s ironic that the secret formula is actually the simplest part to execute.

7X Flavor
8 oz alcohol
20 drops orange oil
30 drops lemon oil
10 drops nutmeg oil
5 drops coriander oil
10 drops neroli oil
10 drops cassia cinnamon oil

We used mostly Young Living essential oils which are food-safe and 100% pure organic. Neroli was a harder one to come by. You want everything you use in this whole process to be food-grade otherwise it can make you sick, and don’t use anything that has been cut with neutral oil. You need full-strength, 100% pure. Once you have the FE Coca and the 7X flavoring components, you can start making the syrup. You probably won’t need to make another batch of either ingredient for a long time. An eight-ounce bottle of 7X will probably last the rest of your life.

Making The Basic Syrup
Since we only made a gallon, we reduced everything by a factor of 5. First, dissolve the sugar in water. Have patience. It can take a while to get that much sugar to dissolve, but keep stirring! Then, add the caramel coloring. We used class IV caramel 050 coloring from DDWilliamson which is designed for acidic beverages, but we found we needed twice the amount indicated to match the color of modern Coke. Next, add your FE Coca. It’s amazing how little you add and how the smell fills the room. Add the vanilla extract, caffeine if you use any, lime juice and citric acid in that order.

Cola SyrupBasic Syrup
.375 oz FE Coca (3/8 oz) or 180 drops
30 pounds sugar
3 oz citric acid
1 oz citrate caffeine
2.5 gal water
1 quart lime juice
1 oz vanilla
1.5 oz caramel coloring

Add 7X
The final step is to add your 7X flavoring to the basic syrup. It feels really exciting at this point, like you are participating in a time-honored ritual or building a magic potion. You need to add only .5 oz of 7X per 5 gallons of basic syrup. Our fractional reduction in quantity had us adding 7X by the drop. If you do a little research you find that most people calculate that there are 480 drops of liquid in one US fluid ounce, but drops per ounce will always depend on how thick the liquid is, or how much surface tension exists. We went with this common measurement and added 48 drops. If you are making the full 5 gallons of syrup you can measure a half ounce, but if you want to make less, do the math and add 7X with a clean eye dropper.

Make Cola
Mix up some cola using 1 part finished syrup to 5 parts carbonated water. We presented our homemade Coke the other day at an office pot luck and it was a big hit. Everyone loved it. Some said it was actually better than regular Coke. After first mixing the syrup, we detected a strong lime flavor in the finished soda, but over the course of several days refrigerated, it has mellowed quite a bit. After six days, the fresh citrus flavors have less impact in the final soda, and it’s getting very hard to distinguish it from the commercial product. If you decide to make this yourself, we’d be curious how yours turns out. And now, at long last, we come to our Drink of the Week. Of course, you can avoid all the hassle above and just buy some Coke to mix with Rum and a squeeze of lime, but what fun would that be?

Cuba Libre (Rum and Coke)Cuba Libre
2 oz white rum
.75 oz homemade cola syrup
3.75 oz carbonated water
squeeze of lime juice

Build in a glass with ice and give a stir to make sure the syrup mixes completely. Garnish with a lime wedge.

Rory, You should be using class IV d150 caramel color designed for stability in acidic beverages. I obtained a small sample from DD Williamson working directly with them, but knowing others might be interested in buying small quantities, I asked their sales rep the same question. They suggested contacting their partner, colorMaker in Anaheim California who will sell as little as a quart. That’s much more than you will need. I have not worked with them, but their phone # is 714-572-0444, or was when this was first written. I have also seen caramel coloring for sale by baking retailers,… Read more »

Fantastic! Thanks for the update. I am looking forward to hearing how everything turns out. By the way, the last few batches I made have allowed me to experiment and draw some interesting conclusions. First, the vanilla extract is important. Cheap, bottom shelf grocery store vanilla definely tastes different in the cola than a high quality vanilla extract. My best results have come from vanilla I make myself using vanilla beans, high proof rum, bourbon or vodka. Second, I have noticed that white granulated sugar works best. Natural, or “raw” sugar that is light brown in color contributes flavor. It’s… Read more »

For the 3 oz of citric acid, is that citric acid (liquid) or citric acid (powder)?

If the former, what is your dilution rate? I usually do 2.5:1.

There are only a few tips I could give. The essential oils may be difficult to find on amazon and a little expensive but they will last a very long time once you create the 7X formula. For the oils, just make sure everything you purchase is organic and food safe. Also, the home made vanilla extract is much better than using some from the store. You are right. I used vanilla bean and a 151 Demerara Rum called LemonHart. This high proof rum has a lot of flavor and is very complex for being an ovenproof rum. You could… Read more »

Rory, Thanks for the additional notes. Regarding heating the mixture to dissolve the sugar–that’s a step I haven’t done. There is differing opinions about using a cold process versus a hot process for making syrup. Some claim the heating creates invert sugar which is complex chemistry stuff that basically results in sucrose splitting and forming gluose and fructose. Fructose is supposedly sweeter and the inversion of the chemical makeup is said to improve stability by reducing crystallization, but fruit acid has similar effects by inducing the inversion. I have had better luck with clean bottles and no heating. With ginger… Read more »

Using the amount of 60% alcohol suggested I couldn’t even moisten half of the coca leaf, never mind get any sort of extract. How could 6oz of fluid be anywhere near enough for 16oz of powder? When I mixed them together, the alcohol didn’t even penetrate halfway down. Most of the coca leaf was still completely dry. I used an ounce of fine powder coca leaf and needed to use about 3.5oz of alcohol. I have no clue how much of this to use in my syrup. Should I just multiply it by a factor of how much more liquid… Read more »

Yeah, the listed solvent quantity isn’t right at all, but as Randy pointed out, the Sulz recipe basically says to keep adding solvent until you’re satisfied with your yield. The procedure I used for my FE coca was to steep 1 oz of powdered coca leaf in 3 fl. oz. of 60% ethanol for 48 hours, then pour the whole mess into a coffee filter, add another 1.5 fl. oz. of solvent over the top, and allow it to percolate for 2 hours. The yield was about 2 fl. oz, and it’s some pretty intense stuff. I added it to… Read more »

Thanks for the response. So even though you had more, you used the same volume of liquid (0.375oz)? I was thinking that if 16oz of liquid was the final output for 16oz of leaf, then with a 2oz of liquid final output for 1oz of leaf you should use double, 0.75oz. Know what I mean? Maybe the relevant solutes in the coca leaf form a saturated solution even with double the solvent.

Drew, You are right. The recipe for making FE Coca is pretty ambiguous. According to the old book, you should be using a lab percolator. I can only imagine that the proper pharmacy equipment somehow allows you to saturate powdered coca leaf as described, but I too found the amount of alcohol nowhere near enough to do the job. I added enough to saturate and barely submerge the leaf as the book also describes. To me, that seemed to be the point. 48 hours later, the drained extract was dark olive green, aromatic, and according to the old book, I… Read more »

The old book does say that, but it’s based on starting with a pound of coca leaf. I had only 4 ounces by weight of coca leaf tea, so I assumed my FE yield would be a similar fraction less than 16 ounces of liquid described in the book. This makes the amount of saturating alcohol even less logical since I had to use more than the book specifies with less leaf matter. I suppose if I was going to rewrite the book, given my experience with this, I’d say: Using an appropriate apparatus for the maceration, saturate and submerge… Read more »

You might try making a fraction of the recipe to test your 7x. I have been making 1/2 gallons of syrup successfully reducing everything by a factor of ten.

That’s a good point. I didn’t think about that but you are right. I think my cola may have lost a little of the initial flavor it had when I first made it.

Octavio, You are right, it’s getting hard to find. Makes you wonder about the supply vs. demand. It has to be a difficult product to sell while avoiding misinformation and controversy. I expect folks like us trying to make historic coca cola reproductions are not exactly keeping these sellers in business with very many sales, and with the ease of product misrepresentation, who knows how Amazon deals with such things. In any case, I did see that LaTienda.com is selling 100 bags of organic coca tea. That’s more than enough. As a last resort, you could try making cola without… Read more »

Regarding LaTienda.com, they are a decent vendor. I purchased a wonderful classic steel paella pan and woven grass serving tray from them–both awesome. LaTienda ships fast and carries great products. I wouldn’t hesitate getting the coca tea from them.

I had posted previously where you can get the Coca leaves as well. I bought mine from a site called BuyCocaTea.com. It was about $40 for a 200 gram brick of ground leaves. This site you are ordering them from is based in Peru, so you are getting them straight from the farmers, basically. It took a while to get them and, if I’m being honest, I was a bit worried that it would be confiscated by U.S. customs or something and I would never receive my Coca leaves! But, they finally came after a couple of weeks and I… Read more »

I also use anhydrous caffeine from Amazon. A small container is cheap, although one must take care to measure properly as this much caffeine is dangerous. In other words, buy a small precision scale and keep the caffeine out of reach of children. I would be very surprised if your coca was direct from a farm. It’s far more likely that to sell as tea it undergoes the process to remove the cocaine alkaloids first. I would expect Peruvian imports to be highly screened and that customs/DEA checks would have to recognize this tea as safe and legal for it… Read more »

Well, you know what I mean… not DIRECTLY from the farmer, but the farmers are in Peru and my Coca leaves shipped right from Peru, so it is close to the source. That’s all I was trying to say. (Not like it came from China where it was shipped to and re-packaged or something…) I DO need to get a scale myself to accurately measure the caffeine to be able to properly dose it. I tried looking up estimations based on how many milligrams might be in a teaspoon or something, but it is only a rough guess and depends… Read more »

Kevin, regarding the caffeine, I have tried the dry measure conversion and it was problematic. I ended up with too much caffeine and you could feel it! The beauty of anhydrous is that you can pick up a can of soda, read the milligrams and simply do the math to match commercial products exactly. Regarding heat, I have three comments. First, I don’t use heat. Not at all. Everything needs to be clean. It was Rory above who suggested heat in a comment and later expressed some regret that it may have affected the flavor retention over time. I don’t… Read more »

I just happened to come across this recipe, and have decided to give it a go. In my particular case, getting a hold of all the oils will be a hard task. However, I suppose some online purchases from many different parts of the world may be the solution. However, I do live in Bolivia, home of some of the best coca leafs available. So I will be trying this recipe with raw, all natural, just harvested coca leafs. Now, to make things clear, using these leafs will not get you high. Even though the alkaloid is contained in the… Read more »

What’s the longest you’ve let the final product sit? I’m interested in making a full keg of this for a party but am worried it might separate in the time it takes for keg carbonation to set in.

Randy,
I just happened across your post while searching for homemade soda recipes.
Is there a way that you could break this down into a much smaller batch recipe?
I don’t need enough to last a lifetime!
I use essential oils, so those are not an issue, and I have a source for the vanilla and alcohol. I would need to purchase the coca leaves.
I’d like to make like maybe a quart of concentrate at a time?
If that is possible, how much of the concentrate would be used to make a liter of soda?
Thank you!!

Thank you Randy, for sharing all this!

Somehow I missed out on hearing about the TAL information and just recently found out. I love Coke and am sad about where the company has taken it. Here in Michigan, the Coke changes almost changes from batch to batch.

I’m going to make a 1/10th batch this winter. Is there anything you would change, at this point?

Thanks again!

I suspect that the caffeine is the more important item to work on. I’ve tasted home made pops with and without it, and there is a difference. Perhaps a little sharper, but it’s hard to describe. So if you’ve had good luck before, I think adding caffeine will take this a step closer.

Did you use organic sugar?

Right! Thinking about what was available in 1886, ‘organic’ was likely what was common; cane sugar.

Have you ever heard anything about the formula for Mexican Coke?

Well, thanks again for this. I’ll definitely check back here to see if others are doing stuff with this. And I’ll post when I’ve made a batch. I shouldn’t drink it often but it would be great to take it to parties, etc. I have lots of friends who prefer Coke to anything else.

I love the net. ;-)

Hello, making Coca-Cola like this is something I have wanted to try for years. I thought I was the only person crazy enough to try this. Thank you for posting all the great information! Can i ask – what brand of neroli oil did you use? I tried to match it with the picture you posted, but I am not sure. Thank you!

Thank you for the information. I have an old book of formulas from 1919 and the describe a procedure for making caramel coloring. I also found the following link on the web. https://www.justapinch.com/recipes/dessert/other-dessert/caramel-color.html Can I ask what brand of scale you used to weigh some of the ingredients? I have a gram/oz scale, but I am not sure of how accurate it is.

Thank you for the information! I have found procedures to make caramel coloring on the web, but I am not sure how well that would work. I would much rather find some pre-made caramel coloring. Can you indicate what brand/model scale you used? I have an older digital grams/oz scale, but I am not sure how accurate it is. Funny you should mention vanilla – as that is the very first thing I plan to make is some high quality vanilla extract, since it takes at least a couple of months to make. I am lucky that I can buy… Read more »

Thank you for the information on the scale. I am getting my wish list together and just like any drink or recipe, the better the quality of tools and ingredients will always add up to make a better final result. I would bet that the ingredients we are using will result in a better quality soda – then even Coca-Cola themselves currently make and this is their flagship product! This brings to mind a super high-quality sugar made by C&H for professional bakers that I use for all my recipes. You can taste a pronounced BETTER flavor using this sugar,… Read more »
