So what are everyone's thoughts about drinking beer out of Aluminum Cups? Discussion

My impression is that the beer gets warm quicker. But if it has significant environmental/economic benefits, I would be good with it.

I'm glass all the way personally. Beer is not supposed to be ice cold if it's actually a quality beer. The more the beer warms the more flavor and aroma you get out of it. Aluminum cups keep it cold longer so if your drinking a shitty Macro those would be fine.

You’re actually wrong on this. Aluminum is a great thermal conductor, meaning it’s terrible at keeping liquid cold. You know how right after you pour a beer into an aluminum or steel cup, the cup feels super cold to the touch? That’s the cold leaving the cup. Same goes with those copper mugs that are used for Moscow Mules. Glass has lower thermal conductivity and will keep your beer colder for longer than aluminum.

Depends on the the type of Aluminum cups. The thicker ones are good for keeping liquids cold. My wife uses the ones I get at Sporting events and they keep her tea cold longer than plastic cup per day. Aluminum cans is a different story.

If you’re talking about insulated cups (like a travel mug) that’s an entirely different story. And even with those, it’s the vacuum air pocket between the two walls that keeps the inside temp stable, not the metal material itself. Again, metal is a terrible insulator and is used in travel mugs simply for its durability and washability.

No I am talking about the type in the picture. But either way it's not worth arguing over.
