What do you mean by cup?
Plastic? Styrofoam? Ceramic coffee cup?
I was thinking just a regular cup - so yeah, ceramic that would be then I guess - or from a mug (are mugs from ceramic too?)
I hadnt even thought about plastic - no, yeah, plastic also tastes worse, yes, but that's more intuitively understandable. But why would water taste better from a glass than from a mug or regular (coffee, tea) cup? And yet it does..
Blacksmith, I too think Coke taste better from a bottle than a can - I mean, if you drink it from
the bottle or can, I dont think I can taste the difference once its poured out in a glass. I dont see much difference between a plastic or a glass bottle either tho, but a can is really worse, yeah. I always thought that - apart from the physical comfort about the drinking thing - it was about the gas. If you drink it from a can, the gas is all up there, too much.
