I don't drink much soda, maybe a coke once a year. Over the years the taste of coke has changed. Every year when I get that craving and drink one, it tastes different. So either the recipe has changed multiple times and there isn't one true coke flavour, or my taste buds might be faulty.

The sugar sweetened Coke’s are unique, but I think McDonald’s consistently has the best Coke you can get. Unlike most restaurants, they store syrup in stainless steal containers instead of plastic bags and they use a higher syrup to soda ratio than most places.

I’m not sure if the flavor has changed much in the past 30 years, but I do know that a McDonald’s Coke is almost always good.

You should try the Coke made in Mexico. Easiest way I find it is by searching for “Mexico coke” on uber eats or something similar.

Most stores carrying products made in Mexico have it.

Coke is actually very different from country to country and less so from state to state. This is because Coke uses local bottle companies and they might be using different water. The coke you buy at your local store is probably bottled somewhere close to keep shipping costs down.

If you're a fan of Dr.Pepper, you'll notice they have 2 different bottles based on where you buy. That's because in some regions, Dr.Pepper uses Pepsi for bottling and in others it uses Coke bottlers.

It's not only the water, there are more differences like high fructose corn syrup versus other sugar forms.

Another one is that in many countries Coke and Pepsi use artificial sweeteners even in their "original" product lines, which is plainly misleading.

Coke isn’t even consistent between factories, different bottle sizes and cans.
djtango 7 hours ago|||
Yes - not about coke but my understanding is that Heinz invested a lot of money over the years to standardise the taste across factories, countries and tomatoes themselves.

Coke itself is not consumed in a containerless 0g environment so the container itself imparts taste - hence why aficionados will often prefer glass over pastic or can. The bottling processing factory will also impart a taste, as will the local humidity which is why I often think drinks taste odd in Singapore.

My fav thing I heard was back in a chemistry lab someone told me a rumour coke had invested serious R&D into a plastic/surface that tastes like lemon to accommodate for the regular plastic taste that leaches from their bottles.

Interesting! According to [1] it's labelled as "less sugar" though, so it's not as if the original/standard Coke is different. There seems to be some widespread thinking that Singapore has issues with sugar consumption so I guess this is Coke's response (or perhaps they were forced by authorities).

That's my experience but I'm not much of a Coke drinker.

I recall some years ago Pepsi making the claim they could replicate Coke to the point of it being essentially indistinguishable but that's wasn't the point, their branding required Pepsi to be clearly differentiated from Coke—commercially that seems to make sense.

It's unclear how accurate Pepsi's claims are but they seemed to be based on tasting trials where people couldn't tell the 'clone' from the real thing.

Seems to me Pepsi was likely right, if we consider how close this formulation is to Coke and that it was produced with limited resources then one would expect Pepsi with its huge resources to grind their 'clone' as fine as they deemed necessary.

These days, Coke's 'secret' formula is more a publicity stunt than anything else.

Some 30 years ago, someone challenged me to tell the difference between Pepsi and Coke in a blind taste test. After taking several sips, I could eventually tell that one tasted just a little bit sweeter, more sugary, and the other one tasted just a tiny bit more... "dark" is how I put it at the time. (Note that I was using that word to describe a flavor, not a color. I do not have synesthesia, that's just the best word I could find to describe the subtle taste difference). I guessed that the slightly-sweeter one was Pepsi, and I turned out to be right.

Thing is, since doing that taste comparison where I alternated sips several times between the two, I've consistently been able to tell if a drink was Pepsi or Coke. So while they are very very close, they are distinguishable to some people, if those people have trained their taste buds. (Or at least they were up to about 10 years ago, I don't know if they've changed the flavor in the past decade because I practically quit drinking soda at all once I got serious about maintaining a healthy weight.)

True story: I was once (late 90s, I think) made part of an impromptu taste-test in a 7 Eleven store in Stockholm [1], when a (probably bored) employee grabbed a Coke, a Pepsi and a Dr Pepper and some espresso-size paper cups and made me and some friends close our eyes and try to guess which was which.

I remember being upset since he claimed I failed to even point out Dr Pepper, which I still think is unbelievable since even its smell is super distinctive and way different from a cola.

> Some 30 years ago, someone challenged me to tell the difference between Pepsi and Coke in a blind taste test.

I did something similar with co-workers recently, who didn't believe there is a meaningful difference between brands. I blind-tasted 6 different glasses and got each one right. I got my favorite (Coke) right just by the first smell, I just had to taste to see whether it was diet or not.

Not that this is a skill or anything. Its just that each of the brands I tasted has a strong characteristic flavor to me, and the difference between real sugar and artificially sweetened is also stark. I've been drinking diet versions for ages precisely because the sugary ones are just too sweet for me.

But the difference is Pepsi would also have had dedicated laboratories and food scientists, scientifically controlled exhaustive testing and unlimited access to any ingredient they wanted. Thus one would expect Pepsi's testing to have had much finer granularity than in this YouTube video).

With millions of dollars tied up in just a few percent of sales you can bet Pepsi knows just about as much as Coke does about Coke's ingredients (and vice versa of course).

The research for both companies is more about the fine minutiae—keeping an optimal differentiation between the two products more than treading on each other's territory. Trampling over each other for market share is done through advertising, not by making their products the same.

Or they could also just hire ex-Coke employees who might have been involved in some sourcing of the ingredients (eg when setting up new factories).

Pepsi probably also has had access to Coke's supply chain and long ago acquired samples of various inputs before mixing, which would make analysis easier. The two companies know they're competing mostly on production management and brand image, not secret ingredients. A decade or so ago a secretary from Coke tried to sell some of the company's "secrets" to Pepsi. Instead of jumping on the opportunity to get Coke's secrets, they contacted Coke's legal department and the FBI, with the three working together to prosecute her.

I think it's obvious that a corporation the size of Pepsi could replicate the taste of coke if they wanted to. But why would they - their customers buy pepsi because they want pepsi, not because they are looking for cheaper coke - pepsi is not even cheaper, it's just a different product. Just like 7up tastes different to Sprite.

The amount of sugar in Coke hasn't changed in the last 40 years, and probably longer than that. It's been consistent at ~39g/12oz, even through the "New Coke" debacle. Wouldn't be surprised if Coke in the 40s, with sugar rationing, had less sugar though.

"The amount of sugar in Coke hasn't changed in the last 40 years,…"

Likely so, but there's some evidence it's different in different markets. That's why I made my reference point the 1940s. I first tasted Coke in the late 1950s in a market outside the US and it was definitely less sweet than it is nowadays.

When I was a kid I thought it was insane that my dad watered down orange juice as he thought it was too sweet. Now that I'm nearing his age at the time, I water down my cola (with plain carbonated water) since I find it too sweet. So I would chalk it up to changes in your taste over changes in the product.
hilbert42 4 hours ago||
I too thought it was my palate and perhaps it's partially so, but it's also more than that. We're now in an era of 'engineered sweetness' to maximize sales.

Since around the 1970s food manufacturers have been increasing the sweetness of products to keep up with the population's shifting/increasing "bliss point". The "bliss point" is defined as the optimal sweetness of a product and it's been increasing over time from the constant bombardment of ultra refined food products. It seems we've adapted to the ready availability of readily available sweet stuff and now we need more to satisfy.

Decades ago, very sweet products weren't encountered to the same extent as today so the bliss point remained essentially static but in recent years as the average bliss point has increased manufacturers have increased the sweetness of products to compensate. There are many references to this, here's but one:

https://www.foodtimes.eu/consumers-and-health/bliss-effect-u...

Re Coke, when I was a kid, its sweetness depended to some extent on how it was obtained. Soda fountains before modern post mixing varied the radio of Coke syrup to soda which changed the perceived sweetness, also I believe in some countries the syrup came sans sugar (or largely so) to save on transport costs and was bottled (sugar ratios mixed) locally. This arrangement allowed local bottling to set the optimal bliss point for that market.

I remember kids whose parents owned a soda fountain could get the syrup and we'd mix it with soda to suit.

Incidentally, I'm in Australia and here the bottled Coke tastes different to what I've tasted in the US (could be sucrose versus fructose or sucrose/fructose mixtures as sucrose is usually the key sweetener used here).

More to the point, I've friends in New York and several of them have complained to me that they consider their local product not up to scratch and they prefer Coke that's bottled in Mexico whenever they can get it.

I cannot recall whether the Mexican Coke was sweeter or not, or if there was some other difference. Reason: whenever I ate with them they drank Coke whilst I stuck to beer.

The video explains how the gas based mass spectrometers he had (indirect) access to don't normally pick up nonvolatile compounds like tannins. It was a big breakthrough that since he didn't have cocoa leaf extract, and he basically nailed everything else, he couldn't really understand what he was missing until he realised the extract would likely contain tannins.

So there may be other nonvolatile compounds which nevertheless impact the flavour profile. While a lot of flavour is in your nose, not all of it is...

There have been a number of taste tests that show that, when blindfolded, most people can't distinguish between Coke and Sprite, let alone Coke and a close imitation, without the visual cue: throw together enough sugar, acid, and carbonation, and it overwhelms the body's ability to distinguish taste. It's a story often repeated in marketing (like Twitchells' Branded Nation), because forging a distinction between indistinguishable parity products is marketing's job.

I think if you believe this I'd recommend trying it yourself.

I've done this blinded with colas, and it's pretty easy to tell the difference between Coke, Diet Coke, Coke Zero, Pepsi, and Diet Pepsi. You might not know which is which without some history drinking them, but they all taste very distinct by themselves.

Really disagree that these are indistinguishable parity products, or that most people would not be obviously able to tell the difference between them.

rootusrootus 14 hours ago||
I'll say that the 'Zero' products have gotten quite good. Not indistinguishable, but closer than I expected. On a couple of occasions I've inadvertently purchased real Dr Pepper instead of Dr Pepper Zero and not realized I was drinking the real thing. That's high praise for the Zero version (notably, the Diet version of Dr Pepper, while it has a following of its own, is extremely unlike real Dr Pepper).
tzs 10 hours ago|||
That's interesting. I'll need to find some Dr Pepper Zero and try it. My history of Dr Pepper and of diet sodas goes like this.

1. I only drank non-diet sodas. Pepsi was my favorite, Dr Pepper or root beer was the runner up at restaurants the had Coke (which I hate) rather than Pepsi.

2. At some point I started trying to reduce the percent of my calories that came from carbs. I was able to continue drinking non-diet soda and meet my goal but only because (1) I usually only drank a small glass with each meal, and (2) I was able to reduce carbs from other things enough to leave room for the soda.

3. That reducing from other things enough to leave room for the soda got annoying, so I made myself drink diet sodas for a few days. I quickly got used to Diet Dr Pepper and started to enjoy it. Diet Pepsi became OK, but Diet Dr Pepper was better. Once this switch was made and I didn't need to make room for soda carbs I could stick to my carb goal pretty easily.

4. After a few years of that, I had oral surgery. They advised me to not drink carbonated beverages for a week or so afterwards, so I drank water. I was actually fine with that so after two weeks I finished off the 2L bottles of Diet Dr Pepper in my fridge and then just drank water at home for the next few years. I would still have a Diet Dr Pepper or a Diet Pepsi or Pepsi Zero or Diet root beer on the few occasions I ate out.

If I ate out at a place that did not those I would sometimes get a non-diet Dr Pepper or Pepsi and it was terrible. It seemed too sweet. It tasted like someone had mixed some thick sweetener into it so not only was the flavor off the feel of the drink was wrong.

It was bad enough that I would no longer eat out at those places. I'd only get food to go from there.

So now I'm really curious if Dr Pepper Zero will taste good to me or not. If my problem with regular Dr Pepper is just due to the sugar I should probably be OK with Dr Pepper Zero. But if what I really now dislike is non-diet Dr Pepper's flavor it sounds like I'll also dislike Dr Pepper Zero.

I don't know but I recently drank coca cola which my brother ordered and then after a few days, I decided to drink diet coca cola because I was discussing it with my brother and he mentioned that diet and normal coke are the same price and I started wondering if there are negative effects to normal coke and not much for diet coke and they both are same price and I am drinking it for the taste, then diet coke makes the most sense so I decided to order it

Not sure if its just me though but after drinking both diet coke and normal coke the taste gap between diet coke and normal coke felt really huge to me.

You mention about Dr pepper and how strikingly similar Dr Pepper zero is, what are some other drinks which have a genuinely similar.

But now realizing this, I think that there is a difference between diet, zero and normal variants, this is the first time I am discovering this. Time to drink coke zero and coke but the winters are really cold so I might have to wait this winter season

Can confirm, could never stand the taste of Diet Coke, but Coke Zero tastes pretty close to the original to me!
