CocaCola or Pepsi - The human sense of taste & flavor

[symbolipoint]

TL;DR Summary

Wondering if most people can distinguish one from the other, or among yet other cola carbonated beverages.

Just the summary as written. My own impression WAS that Pepsi Cola was a little sweeter, and Coca Cola was spicier and slightly less sweet. I do not remember my impressions of other colas. I would be interested in other details which members may tell.

 

[Greg Bernhardt]

No colas taste the same to me. I prefer Coke.

You must have very strong flavor & taste sensitivity, more than most people.

 

[Vanadium 50]

I have no problem distinguishing them,. Diet sodas even more so. Diet Pepsi is better than Diet Coke and Coke Light is overpoweringly foul.

 

[DaveC426913]

Yup. They're all very distinct to me.

I find Coke a fair bit sweeter than Pepsi, or perhaps Pepsi tastes like watered-down Coke.

The diets are very chemically. I drink only Diet Cola, so regular Coke tastes like a mouthful of sugar.

(Actually, I drink Caffeine-free Diet Cola. Better for my blood pressure as well as better for my sleep hygiene.)

 

[Vanadium 50]

o regular Coke tastes like a mouthful of sugar.

There's a reason for that.

 

[DaveC426913]

There's a reason for that.

Heh. Well, yes. But I mean in particular after getting used to Diet.

Many years ago I had a truckdriver neighbor. Some of his deliveries were to one of the above-named soft drink makers.

One of the things he would bring up in conversations was how the concrete loading docks were being dissolved by some of the ingredients.

Most likely Phosphoric Acid.

He refused to drink their products!

My overall impression is that coke and pepsi are easy to distinguish, I also find pepsi to appear more sweet and thus less balanced. Coke has a bit more fresh and tartness in the balance. But flavour impression is also personal, I thought a lot about this when i was into beer chemistry many years ago. Technical sweetness should be tested I think without the aroma impacting the judgement, I have never tested coke vs pepsi with a clamp on my nose though so Ican't tell. I know from beers however that some beers that are technically less sweet (accouting for all the various sugars and their relative sweetness) may be perceived as more sweet if it contains certain "sweetish" aromas. I think it's hard to judge absoluteness, usually one judges the balance, and a beer that is technically more sweet can taste less sweet if it's balanced with against acidity or bitterness.

Both coke and pepsi contains small amounts of phosphoric acid indeed, which has both coneservative properties and helps to get the tartness of coke. Big complex flavours typically need many the components in balance otherwise it becomes "flat" and one-dimensional.

If I am in the mood for sweetness, I prefer pepsi, but if I am thursty and wants a more balanced refreshing drinnk I prefer coke. I drink them both occasionally. Only some years ago I reluctantly switched to diet versions in these and coffe sweeteners as well. Help reduce dental plaque alot, and the effect was actually striking. And the difference it seems was not just sugar, but sucrose specifically is prime stuff for plaque building! A little detail my dentist never told me, i had to dig this up myself.

"However, among the carbohydrates, sucrose is considered the most cariogenic, because, in addition to being fermented by oral bacteria, it is a substrate for the synthesis of extracellular (EPS) and intracellular (IPS) polysaccharides."

@Fra, what you say about the composition of carbonated beverages also influences other people to stay away from these beverages.

If you talk about health, but like sparkling drinks, aside from the sugar many commercial sparkling mineral waters have additives with more buffer capacity which are also not optimal but if you are in a country with good tap water, a very nice alternative is to carbonate your own water. I do this all the time. The acidity of unbuffert tap water carbed just was gas, is not very high and shouldn't be an issue.

I have no principal problem with additives though, nature is full of chemicals. Life would also be boring if you had to stay away from everything. I see no concern with phosphoric acid in moderation, it is not something unnatural per see. But it wouldn't drink a gallon a day.

Wait till he finds out how many things water (the universal solvent) can dissolve!

Are you REALLY so sure?

One might expect Phosphoric Acid to be an ingredient of some hard-surface cleaners and in some mineral-scale remover formulations (and I actually am aware it might be present in certain pharmaceutical products). One might otherwise reject a beverage containing Phosphoric Acid; and that citric or malic acids would be better. Fruits we eat, as far as I'm aware, do not have Phosphoric Acid in them.

Phosphoric acid also has the potential to contribute to the formation of kidney stones, especially in those who have had kidney stones previously.)

Yes it is, but in concentrated form. Its often used as a less toxic and dangerous than the more efficient scale remover hydrochloric acid, (which we have in our stomach) which is a strong acid as. Phosphoric acid is a fairy weak acid.

Nice additional find! So it's generally recognized as safe. But is that really safe enough? In the long-term?

Dentists will generally tell you that the low pH of sodas is bad for your teeth. But the details of dose and frequency and how much risk are important questions. It may be that the sugar is a bigger risk to your teeth.

Taste the difference between coke and pepsi? Really? Isn't that like a 50 year old question?

Probably, but a few people like to find clearly reliable information, but are willing to look for anything recent and interesting.

I drink no less than 5 cans of Diet Coke a day, every day. My last dental checkup was perfect.

(But I do think good teeth are largely hereditary)

Maybe your day of dental reckoning is going to come. Or maybe you are a statistical outlier, perhaps due to genetics. Or it could be other practices compensate for your five-times-per-day acid washes. Who knows?

I floss about twice a year. So far so good but I'm not tempted to draw conclusions.

OK, how about tasting the difference between US Coke and Mexican Coke (high fructose corn syrup vs. cane sugar)?

To me, the hecho en Mexico version is much better.

That's funny. I always tell people (diet) Pepsi tastes like dirt to me.

I can't say. The Mexican Coke is very popular here but I don't drink the sugar versions unless I really need the calories, which is pretty infrequently. AFAIK there is no Mexican version of Diet Coke.

Made with real Diet Cane Sugar?

I know the difference between swedish coke and US coke.

One of my memories from visiting USA is that the coke you got at fast food chains (where they flavour their own local tap water) smells heavily of chlorine and it threw my throat ecosystem off balance. Not sure if pepsi or coke goes along better with chlorine :) I bet anything off bottle is better. It was similar in all the places I've been to, but all of them bigger cities.

Not certain exactly what you say there, but were any or only the CocaColas you drank were directly from cans or bottles; or were they from drink dispensers, like from a tank delivered through hose & spout arrangement (like in restaurants and fast food stands)? I am heavily guessing something you drank from restaurant or fast food place gave you Coca-Cola's NOT from cans nor bottles. And the shops were very careless with their equipment maintenance.

 

[JT Smith]

Fra is talking about soda on tap. It's usually a plastic bag full of concentrated syrup, water from the tap, and a CO2 cylinder to carbonate it on demand. The bigger chains might take care to treat their water but I'll bet lots of places just use plain tap water. And that water is going to vary significantly from place to place. It's got nothing to do with maintenance, just the process.

It's easy to tell the difference between Coke from a can or bottle and from a spout. Some people claim they can taste the difference between a can versus a bottle but I'm skeptical that would hold up in a blind test where the sodas are poured into glasses.

The taste changes with time too. Coke doesn't age well.

 

[Fra]

Chlorination is part of the common process of producing safe drinking water, but the level of residual chlorine left once the water reacher the taps in the homes, are very low in Sweden than in many some countries, USA seems to be one of them, although I can't speak for all states. I also think once you live there you probably get used to it and don't think about it, but as a visitor there I was shocked to sense the chlorine everywhere, from brushing teeth in hotel tap water, the hotel juice (even hotels with high standard did this) to drinking coke from tap at the malls fastfood chains (all of them).

As far as I now, Sweden use just tiny bit chlorine, but rely a lot on UV light and ozone to desinfect the water.

[gmax137]

although I can't speak for all states

my experience is that the chlorine taste varies quite widely from location to location around the US. It also varies through the year (typically higher in summer).

Who is "you"? Long ago, I sensed the difference. They were both 'good'. If I had the momentary preference for one, I chose it if available.

Have you heard of the Pepsi challenge that was done a few decades ago?

 

[kyphysics]

No colas taste the same to me. I prefer Coke.

I'd like to think the same, but I'm going to try a blind Pepsi vs. Coke taste test after reading this thread. Lots of Coke lovers surprisingly say they like Pepsi better with blindfolds on. I find Pepsi too sweet for me and I like the slightly bitter taste that Coke has. . .

But, who knows...maybe without the brand labeling and JUST my senses (blindfolded), I'd find msyelf enjoying Pepsi more. I shudder to think it'd be true. It would overturn decades of preference. . .we shall see!

When Walmart opens at 6AM today, I'll buy both.
