I think it's all a question of habit. Since most people drink beer ice cold they associate the two. I like it both ways, it just can't be hot.I don't like really cold drinks anyways because I have sensitive teeth. I have beer at room temperature a lot, I really don't mind it much at all.
In winter I sometimes feel like having a beer but i don't want to have something cold. Very often I have beer at room temperature.
How about you have you had beer at room temperature and enjoyed it?
I have never tasted warm beer nor do i intend to do so, i love cold beer.I definitely do not want a really cold beer, but also warm beer is never really my top choice either. I might just settle with a stiff cocktail instead.
