Why is it that water tastes better from a glass than a cup?

When I was young, it seemed that water always tasted best out of a garden hose. Now I realize it was probably just the chemicals from the rubber.

Another youthful delusion shattered!

water
as kids growing up in hamburg , my brother and i thought the water from public water faucets (they were like fire hydrants with a handle , and there was a metal cup attached by a chain) was absolutely great stuff .
our mother very much frowned upon us drinking water and we were told that "...you'll get lice in your tummy if you keep drinking water from the fountain !!!..." .
what i learned much later was , that the fear of drinking water dated back to the 1880's when a cholera epedemic swept through hamburg and killed about 20,000 people in a few weeks - that was before a public water-system had been built .
of course , we disreggarded those warnings and slurped the water as something special - "a forbidden fruit" .

and yes , i too thnk that water tastes better from a glass - tastes worst from a plastic mug imo .

also find that when we visit one of our provincial parks with good grundwater supply , the water and coffee/tea made with the local water tastes better - not as much chlorine !

I think everything tastes better in a glass. Like ice cold Coke. I think maybe it's the taste of the plastic that makes the water taste worse. Or maybe the plastic absorbs something from the water, changing its taste.

I occasionally drink water out of the bottle but agree it tastes nicer in a glass.

That comment about Coke reminds me that I've always thought Coke from glass bottles was significantly better than from a can or plastic. I wonder why?

What do you mean by cup?

Plastic? Styrofoam? Ceramic coffee cup?

I think part of the experience of a good drink of water is the cool, smooth surface of the glass on your lips.

Ice water from a coffee cup just doesn't evoke the same pleasant sensations.

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.

I think that unless they're really new or have a really thick/ high-quality glaze, residue from other things you drink from ceramic cups sticks around (not necessarily visible), enough that you can barely taste it. I definitely notice that when I drink water out of an old mug that E.G. usually uses for coffee.

If the cup is high quality/ thick, in theory it should be the same as glass, since glaze IS glass.

It doesn't, you're delusional. We don't mind, however, and would never want you to feel badly about it.

LOL! Well, thanks Set...

i'm sure even set might agree that this is one good looking glass of water ?
(oops , found it under "constipation in seniors" - never mind me)
