A few years ago I was listening, on the radio, to a lady who was a chief brewer at some major beer maker. Her advice:
1. There is no real difference in beer from different containers - maybe cans are slightly better as they block light out.
2. Important not to drink the beer directly from bottles or cans. Does not allow the drinker to fully enjoy.
Her recommendation was to pour the beer into a glass - it alllows a head to form which gives off aroma (smell is an important part of taste) and allows the beer to de-gas slightly, meaning you will feel less bloated after a few.
I tried her recommendation and now am a convert - take my 6-pack plus 380ml glass (with cooler)
Will now only drink directly from can/bottle if there is no alternative.
Try it!
Cheers
