"The inside of the can is lined by spray coating an epoxy lacquer or polymer to protect the aluminum from being corroded by acidic contents such as carbonated beverages and imparting a metallic taste to the beverage."

I often wonder how good that coating is for consumers. I'd be surprised if it doesn't leach into the produce.

The epoxy resin is mostly BPA. [1]

The article you linked talks mostly about BPA, but the resin only contains it...

sorry, I didn't mean by volume, but rather that when folks say resin they mean bpa epoxy resin.

Certainly a belief among some that soda from a glass bottle tastes notably better.

I'll vouch for that when it comes to beer. It's not just the packaging itself though, but also the experience. Plus, when you drink from a can directly, your lips will touch the outside / top aluminium, which will affect the flavor and experience - subtly, but it's there.

I prefer glass bottles for my beers.

Ahhh the subtle flavours of rat shit. I've never seen someone wash the top of a can before opening it. I mean, would you go around licking random surfaces that other hands have touched, rodents have scurried over and defecated on, etc?

The odds that a hand or rat has touched the top of a can you just pulled out of a box is pretty slim

As an aside, to me Coke from can has a different feel from Coke from plastic bottle. Almost as if the bubbles are fewer and larger when sipping from a can.

Well the carbonation is different for cans vs bottles, and also dependent on the bottling plant.

That has more to do with the use of cane sugar vs corn syrup

Mexican Coke, which uses cane sugar, comes in a glass bottle, but you can also get US coke presumably with corn syrup in a glass bottle and some people do think it tastes better.

> Mexican Coke, which uses cane sugar

This is at least partially a myth.

Here's a study which found no sucrose in Mexican coke: https://onlinelibrary.wiley.com/doi/full/10.1038/oby.2010.25...

Though, it is complicated because there are multiple bottlers making multiple different coke products, and even the same bottlers could shift what sweeteners they use over time, presumably based on pricing.

Then you should also worry about plastic water bottles...

Depends on the kind of bottle; polyethylene, safe; polycarbonate, not safe; polyethylene terephthalate, not great.

Just about every disposable water bottle is PET, which is far down the list of dangerous plastics when it comes to leaching (to ignore for a moment microplastics).
