Always Coca-Cola

Why does Coke (or Pepsi, or Vanilla, or Diet …) always better in a glass or bottle than from a can or mug?

Glass is a more inert material than metal (even coated metal). There is more chance that something in the metal can affect the taste. And anyway, glass doesn’t seem to have a taste or odour, while metals (alumnimum, iron, etc.) seem to have some distinctive flavour to our senses.

Or maybe we’re just imagining it.

No imagining involved, Coke does taste better in glass bottles. I think you are right on the money about glass being inert Ben. That’s why it’s used in chemistry labs.

Pepsi on the other hand tastes like drek no matter what container it comes in. Pepsi Twist is drinkable though. The lemon cuts through the nasty sweetness. Strange that T&T (Vancouver area Chinese supermarket) always prominently features Pepsi Twist … must be big with the Asian crowd.

I agree with Ben about glass is inert material which will not change the taste, and chilled glass stays its coldness better than other material. The other fact is using bottle which has a small opening helps preventing the loss of carbonation. So a chilled classic glass bottle for any carbonated drinks is the best choice for keeping the drink colder, more flavorful, and fizzier.

Best way to drink pop/soda: At an A&W Restaurant, drinking A&W Root Beer, straight from one of those giant frosted mugs.

Because Coke (pretty awful stuff) is acidic and
actually can be used as a cleaner; you wouldn’t want to know how corrosive the stuff can be…
i don’t drink the stuff… but i can imagine
aluminum + acid can’t be a good combination…
there’s gotta be some mild kind of chemical reaction going on there!! in fact any metal in contact with Coke (as long as the Coke isn’t flat) is probably not a good combination….
drink with caution!!!

i think coke/pepsi is the best in metal cans! :)

Wow, all very good points!

And indeed, that is the best way to enjoy a nice root beer. Now I just need to find an A&W where I can run off with those mugs! (Plus one scoop of vanilla bean ice cream and a thick straw, and it would be orgasmically fantastic.)

I’d imagine that the alumnimum (a-loo-min-ee-um, eh, Kev?) would be coated, or else it would corrode/rust with the acid/liquid in its environment. The scary truth is that you never know how long that can/bottle has been out of the factory and in storage, exposed to rat poo and grubby factory workers’ hands, dirt, …

Always, ALWAYS lick the top of the can so it’s clean before you drink from it.

Dude!?!
Licking the top of the cans is a big gross factor, not to mention is not good for your health! You should always, ALWAYS wipe the top of your can, never and I mean NEVER lick the top! And if you think that rat poo and dirty hands is bad in the factories in bad, in Cambodia some consumers had found insects and dirt in Pepsi Cola beverages and had suffered diarrhea.Gross huh.
Anyway glass is way better than can, it keeps it colder and with tons more fizz (there is nothing worse than flat coke) and once you’ve drank it you can keep it, and it looks really cool when you have a collection. Besides I don’t think any of the beer swigging freaks would try and crush it on their heads if it was made of glass. The only down side of glass is it isn’t so good for the environment, not that cans are any better, but other than the enviro factor glass is the way to go!

sorry for the sentence stuff up :)

what?

What’s in coke thats corrosive?

Posted by Dylan Sheen on 20 February 2004 @ 4pm

Hello
Yes your all correct, coke does taste better in bottles. why? I believe that cans and plastic bottles can hold a higher cabination content making it more fizzy!! where is the glass bottles cannot.
they do not have screw on tops they are just sealed on. too much carbination might make them pop.
open a glass coke and look at it, then take a sip then open a plastic coke and do the same you will notice more carbination more “fizz”.Glass has more taste more of that “original flavor” less soda fizz taste. this is just my opinion

Love is two people sipping Coca Cola from the same straw on a warm sunny day.

Plastic leaks overtime, so i believe that softdrinks in plastic have an increased amount of carbon-dioxide, to prevent them from going’flat’ quicker. i find if i release a slight amount of gas from a plastic bottle coke before drinking it (by lightly shaking and slowly releasing the cap), it tastes much better.

Well, you guys all got good points.

I recently helped a boy from 7th grade on his science fair, and it was about the acidity of these sort of drinks. We submerged small pieces of aluminum into the solution for 7 días, and compared the final weight to the initial weight.

Coca Cola was the drink which caused the most corrosion in aluminum.

Definitely acid and metal don’t go together, but aluminum is treated before it comes in contact with an acid. So there is definitely a reaction!

Melissa, I’m sure he was kidding about the “lick the top”

Posted by Matt on 14 April 2007 @ 7pm

You are all wrong. Aluminum does not effect the taste and glass does not make it better. It’s very simple. Please spread this because everyone is wrong!

I went to the coca cola plant and asked, because I my self have been curious. It is not that they use sugar in glass botles and Fructose Corn Syrup in cans and it is DEFFINITELY not the fact that the aluminum is having a chemical reaction lol!.

There is more syrup in the glass bottles. The glass bottles are smaller ( except mexican coke and other bottles I didnt ask about the bigger ones should have!!) but they use the same amount of syrup in the 12 oz can’s in the 8 oz bottles. SO there you have it thats why!

Mexican Coke is different, that I think they actually use real sugar in.

Two quick things: 1. All soft drink and food cans are coated with an organic polymer that is baked onto the cans creating a barrier between the can and the product. Even in cases where the internal barrier fails (giving an off taste to the product), the amount of aluminum found in the beverage is insignificant compared with normal consumption.

2. Cokes are about as acidic as orange juice. Anything you can wash/dissolve with coke, you can wash/dissolve with Orange Juice. Before you stop drinking orange juice too though, neither is as acidic as your naturally occurring stomach acid.

Finally, I’ve always preferred the taste in cans. I always figured it was just the difference in carbonation from one package to another that affected the taste.

I have solved the problem, at least for me.

I thought that perhaps the cold of the bottle affected the taste sensation.

I chilled a thick glass in the freezer. When it was really cold, I poured in cold coke from a can. Voila! It tasted like it came from a glass bottle.

Well I cant explain the taste factor (although I am partial to glass bottles). Someone asked “what is corrosive in coke? That can simply be explained by reading the side of a can. It is Phosphoric Acid.

Melissa said : “(there is nothing worse than flat coke)”

So I’m the only person in the world thinking that the more you shake the bottle and let the gas go, the better it gets ? I always thought that the gas/fizz in the coke makes it hard to drink. Many times you are thirsty and you have to drink very slowly because of that. And that’s anoying. No ?

About the coke acid doing the same harm as the orange juice (or even other fruits) I can confirm that. I was having a bad tooth and drinking Coke made the tooth even more sensitive to cold water and so. And orange juice did the same thing.
