I usually drink a 16 oz can of Becks beer (German brand) at this restaurant in my area and I love it. I then had the Becks beer in a bottle at another place not too far and it tasted different to the point that it seemed like a different beer.
I always had the thought that bottled beer was better but I have to admit, that in my experience this week, the canned Becks beer was much better. I had a similar experience before in Amsterdam when I had a can of Heineken and loved it but in the same town, the Heineken on tap was not as good at a nearby bar. I understand that beer is complex and like liquid bread as they say. I don't always like canned beer. I like Budweiser on tap much better than in the can.
Any theories on this phenomenon on how the taste of beer changes within the same brand?
