There are 3 main questions being considered here.
1. What container is the beer stored in?
2. What container is the beer drunken from?
3. What do your taste buds like?
1.
There are exceptions, but generally the beer is made the same no matter what it is going to be packaged/stored in. Most beers are stored in either aluminum or glass.
2.
Mostly people drink beer out of either aluminum can or glass container ( or at partys - plastic or styrofoam cups.)
3.
Many people say they prefer tap beer to can beer, but kegs are generally made out of aluminum just as beer cans are. Perhaps the surface area that contacts the beer in a keg is lower for the volume contained than the surface area in a beer can. If my lips touch the aluminum in a can, I seem to be able to detect the flavor of the aluminum more than if I pour it into a glass.
Some people grow used to that aluminum flavor and actually like it. Other people like the "Skunky" flavor of a beer stored in a clear bottle like Corona that is subjected to growing other cultures besides the active yeast culture.
It may depend on whether you are drinking an ale or a lager, or something else. Ale yeast cultures are pretty much done right away while lagers keep going sort of like the "active cultures" in yogurt. The beer yeast cultures are definitely affected by the material the container is made out of. Some people believe that trace amounts of aluminum build up in your body and eventually cause alzheimers. Now where did I put the other cans of beer I just bought...................
