Issues with aluminum cups?

[JTC3495]

What about all the beer I drink? I must be screwed.

My friends tell me I'm weird, but I think aluminum imparts a strange taste to water. That'sthe omly reason I don't use it.

I think so too. That's why I go with stainless.

I've never used titanium. How ardent is a titanium cup full of hot liquid?
