Generally the mouth of a can is wider meaning you open your mouth wider meaning you get an enhanced flavour as you use more of your olfactory sensory neurons.

Cans limit the amount of light hitting the beer ( An ol mate neighbour told me years ago never trust beer in clear bottles, he's right )
They have an internal coating now that eliminates the metallic taste of old. They get cold quicker and they're cheaper to make, cheaper to transport and are fully recyclable.[/quote]
Does U Brew It still have their canning machine?
