I don’t drink cola and I’m usually not into chemistry videos, but this was genuinely entertaining. The "Mass Spectrometry" and “What do other people think?” segment was especially fun; great pacing and presentation. LabCoatz is my first chemistry channel subscription :)

One of the really interesting thing (to me) in this video is that the very distinctive "your whole mouth sticks and is slimy from the sugar and even your teeth feel different" can be traced from a single component that's added seemingly for this purpose. And it's the thing I can't stand with regular non-zero coke (well the sugar level too, but that's pure health thing).

It would also be very interesting if he could get his hands on coke from different markets as the formulation varies from country to country. One of the most obvious is the amount of cinnamon, but it would be very interesting to know if more differences were there.

Another interrogation of mine would be if, sugar aside, the formula is different between regular coke and coke zero. I'd bet is is, simply to offset the aftertaste that aspartam/artificial sweeteners have, but I'm curious if other non-sweetness related ingredients do change.

"cloying" is the word you're looking for for that sugar mouthfeel
SamBam 1/12/2026||
I've always assumed that's either the corn syrup or something else that's in the American version, because I swear growing up in Italy I never noticed this.

Haven't done a side-by-side comparison, though, so maybe it's just my memory of my childhood tastebuds.

tuetuopay 1/12/2026||
I live in France and there definitely is this feeling. I may be biased, because I only drink coke zero, which has a distinct "dryness" to it wrt other sodas. However, it's the only non-zero soda where I notice this feeling.

Children have a much more sweet tooth than adults, so it may be the reason you did not notice it, as it would not necessarily register as bothersome. I liked to bite into direct sugar cubes as a kid, which I would definitely not stand today.

lurn_mor 1/8/2026||
Quite informative, and a laundry list of flavor names/chemicals that sound far more dangerous than they taste. Interesting find is vinegar, which might have offered a small germ-fighting benefit and given Coca Cola the 'medical' qualities it initially sold for...
halapro 1/11/2026||
The ingredients he uses are not necessarily what CC uses, but they're just a way to replicate the flavor profile. Notably he lacks the coca extract so he has to make up for it.

I think that the cocaine was the origin of its medical debut.
colechristensen 1/11/2026|||
It was a reformulation from a popular drink where wine was infused with coca leaves and kola nuts, popular with Pope Leo XIII who appeared on poster advertisements for it. (and many others)

Georgia passed prohibition and coca-cola was an invention to replace the now banned beverages.

fiftyacorn 1/11/2026||
Is that tonic wine? Like buckfast?
colechristensen 1/11/2026||
Same kind of thing as Buckfast, long out of production but somebody tried to revive it a decade ago.

Cola nut also contains caffeine, so quite an energy drink between the two.

I was surprised to see nausea meds for kids that's phosphoric acid and sugar...

I thought it was well known that Coca Cola contained phosphoric acid. It's one of the reasons why it's so bad for your teeth.
leetrout 1/14/2026|||
Indeed, I think it is and I was given coke for my tummy as a kid so I was making the connection between coke's medicinal properties to on-the-market nausea meds.
zahlman 1/12/2026|||
It's explicitly listed as an ingredient, even.

I mean, uh, we used to not have any laws about this stuff:

to me the impressive thing is Coca Cola was formulated in the 1800s and yet even with modern equipment - most people fail to replicate it.

the original chemist who made Coca Cola was a genius

diego_moita 1/12/2026||
You're assuming that the company uses the same formula as then. That would be really awesome.

The original formula contained coca leaves (the raw material for cocaine) and extract from kola seeds (that's where the name comes from).

Beverages containing cocaine were very common until the beginning of the century (search for "Vin Mariani"). Even today you can buy coca leaves in the supermarkets of some Latin American countries (Bolivia, Peru, etc).

An huge corporation using the raw material of cocaine to produce the most popular soda in the world would be the funniest story of our times.

Eisenstein 1/12/2026||
> An huge corporation using the raw material of cocaine to produce the most popular soda in the world would be the funniest story of our times.

Coca Cola does still use coca leaves for its flavor:

"In a telephone interview from Coca-Cola's Atlanta headquarters, Randy Donaldson, a company spokesman, said, ''Ingredients from the coca leaf are used, but there is no cocaine in it and it is all tightly overseen by regulatory authorities.''"

...

"Bales of coca destined for Stepan and, ultimately, for Coca-Cola are shipped to the Maywood plant through ports in New York and New Jersey, Mr. O'Brien said. Each shipment carries its own import permit, also issued by the D.E.A."

Inventing and replicating face different challenges though.
richardatlarge 1/8/2026||
It would be interesting to know more about how it's actually manufactured and whether he has ideas about why the classic formula was changed -- maybe something to do with the cost of one of the steps, which the video suggests could be true, as it's damn complicated
mattmaroon 1/12/2026|
At a high level: probably they buy flavors from the flavor houses by the rail car or tanker truck and mix them with water, sweetener, and gum Arabic. I’ve seen it at much smaller scale, but I bet Coke has some amazingly large machinery given the scale.
ge96 1/12/2026||
Coke is nasty, literally feels like my teeth are dissolving the moment I drink it. Not to detract from the amazing science. I am still guilty drinking the sugarfree redbull and for soda if I would drink it, mountain dew.
anishgupta 1/8/2026||
I didn't see the full video, but in a nutshell its quite some effort. For a person who has a bad tastebud like me, every dark colored carbonated drink tastes almost the same to me :(
glemion43 1/8/2026|
You are not missing anything though.

Just a lot of sugar

tjwebbnorfolk 1/12/2026|||
There's a lot of reasons Carbonated Sugar Water, Inc. isn't a $200B business, and Coca Cola (tm) is, that "just a lot of sugar" doesn't even begin to explain.
yodsanklai 1/12/2026|||
Coca Cola is often mentioned in the first lesson of a marketing class. The product would collapse without the huge amount of money they put in advertising every year.

Distribution network and marketing.

that's a very oversimplification of it. how people can be willing to consume a beverage that can be used to eat the corrosion off of battery terminals is beyond me. so they'd be missing that on top of the sugar, unless of course they are drinking the sugar free versions, then it's just the battery cleanser

> how people can be willing to consume a beverage that can be used to eat the corrosion off of battery terminals is beyond me.

Wait 'til you find out what water can do.

I do get your point, but really, it's just corrosive in a different way than the usual highly corrosive stuff we consume daily.

jrochkind1 1/11/2026||||
> can be used to eat the corrosion off of battery terminal

That's just acidic, orange juice will do the same thing. But perhaps you are amazed people are willing to consume orange juice too!

mattmaroon 1/12/2026||||
Luckily I have zero battery terminals inside me. Any acid would eat the corrosion off a battery terminal. Orange juice probably works.

Chemistry is scary to those who don’t understand it because it gets used for this type of sophistry.

tjwebbnorfolk 1/12/2026||||
I'm drinking a coke right now. The reason? I like it.

Also I'm not sure how the pH level of a food is relevant to anything

mrguyorama 1/12/2026||
The PH level of a food in fact can make it delicious.

Sour is one of the main "flavors"

rootusrootus 1/12/2026||||
About the same acidity as lemonade. Less acidic than the stomach it is going into. There are far more pressing things to worry about in this world.
Arch-TK 1/11/2026||||
Lemonade (made from real sugar, water and lemons and nothing else) can also eat the corrosion off of battery terminals...

The marketing and trademark is more important than the formula. If you created and sold a perfect Coke clone you wouldn't make a dent in their market share. You could make one better than Coke and not make a dent because it wouldn't be Coke.
netsharc 1/11/2026||
I think his idea was to make a very close copy that costs very little compared to the finished product, to e.g. save cost of your own consumption (in the video it says he made a mixture that can be mixed with water and sugar to create 5000 liters of Coca-Cola)...
mattmaroon 1/12/2026||
I formulate, bottle, and sell beverages and I’ve used many of these ingredients. They are very potent, so yeah, the ingredients other than sugar are only a tiny fraction. They can be hard to source in small amounts sometimes though.

The non-nutritive sweeteners in their pure form are wild too. They are 2 + orders of magnitude sweeter than sugar and they come in very fine powders. You have to mask up when you work with them if you don’t want to taste vague sweetness for awhile.

proverbialbunny 1/12/2026|||
In Australia Coca-Cola isn't allowed to import coca leaf extract for flavor, so it tastes very similar to one of the 3rd party knock off brands you'll find in the US. In Australia everyone drinks Pepsi because of this. Without the coca leaf Coca-Cola tastes imo pretty terrible.

What makes this video revolutionary is he was able to find an alternative to the coca leaf that has a near identical flavor. If it's as good tasting as advertised this knowledge could empower 3rd party producers to make a coke drink that will finally rival Coca-Cola in popularity.

scoopertrooper 1/12/2026||
There is nothing true in this comment

* Importing coca-cola extract with coca extract is legal

* Coca Cola is significantly more popular than Pepsi in Australia

toast0 1/12/2026|||
I would bet that supermarket brand cola would sell more than it does now if it were closer to Coke.

I think sooner or later, everyone who drinks a lot of soda will try the store brand as well as other colas that are non-belligerents in the cola wars. Some of them are ok, some are good for some mixed drinks, some are so bad I won't even finish the pack. Even though I prefer Pepsi, if I knew brand X was pretty close to Coke, I might choose it when it costs less and money is tight.

mnau 1/12/2026|||
My country is going to require a recyclable plastic bottles. That means bringing empty plastic bottles full of air into a shop, so a machine can squash them and send somewhere.

This will bring down marketshare significantly. It's incredibly hassle, which is likely the point. I am looking for good and cheap sodastream cola syrup, but they are very expensive.

mattmaroon 1/12/2026||
Both Pepsi and Coke did make beverages people preferred. The Pepsi challenge did make some dent in their market share (but Coke is doing just fine) and New Coke ended up just selling more old Coke. So your story checks out
