Wait for Spring and find some yellow-capped 2L bottles of Coke. Those are Kosher for Passover so they don't contain any grain (corn), just cane sugar.

I would love to do a blind taste test. It could also be the aluminum can.

Even if a placebo, it's still true - I can't stand canned coke. I can't drink it, the taste to me is horrible.

If you had the energy to do so, you could try to replicate his results, i.e. buy a Mexican Coke, an American Glass Coke, and an American Can Coke, and decant them all into glasses or cups at home, then see if you can taste the difference.

If all your brain/tongue perceives as horrible is the taste of the aluminum can, you could always switch to buying Coke in glass bottles, which are more expensive than cans but still cheaper to buy in bulk than Mexican Cokes, and can be found at most grocery stores.

Or, if being limited to Mexican Coke means it reduces your overall soda consumption because you're only able to drink it when you're near a Home Depot, keep doing what you're doing. You'll probably be healthier for it.

Or just pour it in a glass?

That would be a different test, methinks?

You're assuming that the taste is only affected by what it's being served in, not how the liquid was transported. For all we know, aluminum imparts some sort of off-flavor into the Coke itself that the OP doesn't like, in which case it wouldn't matter if he decants it into a glass first--it would already have been "tainted" by being held in the aluminum can.

It may again be placebo effect, but I can still taste the difference in bottled water poured into my steel water bottle and my usual filtered tap water.

I also can't stand plastic bottled sodas, and can tell they've been sitting in one even if drank out of something else after opening.

I fear the bottling/canning process and length of time spent in it gives it a bit of a whiskey-barrel style finishing taste alteration.

Also need to add McDonald's fountain Coke for sake of science.

Most soda is too sweet for me. I really enjoyed Club Mate, quite a bit more refreshing and way less sweet than Coca-Cola.

> way less sweet than Coca-Cola.

And twice as much caffeine per ml.

Exactly, it's the engineer's cola
