Coke isn’t even consistent between factories, different bottle sizes and cans.
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.
I actually had beer in mind for Singapore which I find somehow always tastes a bit off here...
This is 100% correct, I had to chuckle though when the thought of an actual living person considering themselves a "soda/coke afficionado" entered my mind.
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.
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.)
I don’t have trained taste buds, but something in Pepsi is off putting to me. Worse is artificial sweeteners, which I think I’m have whatever mutation makes aspartame taste bitter. I could never understand why people like Diet Coke, but it turns out I’m the strange one.
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.

Bottom line: the brain takes a lot of shortcut to allow us to take decisions quickly and is easily fooled. We aren't much better than a tiny LLM model really.
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.
Pepsi has more vanilla and lemon. If you go do a blind test now I bet you’ll find them easy to tell apart.
I reckon from experience that's correct. For example, I can't drink Pepsi Max as it's far too sweet (all I taste is sweetness, on its own that's not very appealing).
It probably didn’t take them terribly long to do it
Some people perhaps. Restaurants usually only carry one or the other so you don't get a choice.
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.
Most trade secrets aren't really all that secret.
It would be informative if we actually knew how much sugar was in say tbe wartime Coke of the 1940s compared with that of today. I reckon the difference would startle us.
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.
Except for when it has. e.g.: https://www.cbc.ca/news/business/coke-cuts-sweetness-in-cana...
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:

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.
Also where I am (Australia) it's always sucrose (unless fully imported) because of the large cane sugar industry in Queensland.
