Why does beer taste bad from an aluminum bottle?

I am an analytical chemist and have run into the problem of adhesives used in the production of certain containers/caps leeching out of the container/cap and contaminating my samples, it happens quite often and I'm thinking this could be the reason since they probably use two different manufacturing techniques for the Al bottle vs. Al can.

Budweiser Aluminum Bottle

I don't drink beer, but I've heard it supposedly picks up the tin taste from the can after awhile, especially if you drink it right from the can. But if you buy the beer in cans and then drink it within a short period of time or drink it out of a cup instead, it should be fine and won't have time to pick up the "tin taste". You shouldn't let beer sit longer than 2 months anyway, so as long as you drink it right away, it shouldn't matter. You should test it though and see if it's just a rumor. Buy a case or 6-pack of beer in bottles and 6-pack of the same brand in cans. Then pour both into cups, close/cover your eyes and have someone switch the cups around so you don't know which is which, then taste-test both of them. See if it really tastes all that much different. If it doesn't, then you will feel better about buying imported canned beer, if it does taste worse, then don't worry about buy imported beers and stick to the bottles you normally buy.

Because the metal leaves a metallic flavor on it whereas glass is 'flavorless.' Budweiser is a very light beer, so any impurities in it would be more noticeable than a darker beer such as Guinness.

its not bad, i like a glass bottle better though
