On occasions, such as family social gatherings, I have tried canned versions of premium beers such as Abbot Ale. However, compared with bottles they are always disappointingly lacking in condition. These are not the “draughtflow” beers containing a “widget” (which in my experience always taste like foamy dishwater) but it seems the manufacturers deliberately make them less gassy to try to replicate the feel of handpulled beer in the pub. However, all they succeed in doing is producing something that is just, well, flat.
Interestingly, non-widget cans of ordinary bitters such as Tetley’s do not share this characteristic and so, despite their inherent limitations, are actually more palatable. In general it’s best to stick to bottles, though - cans of ale may be cheaper, but they’re a false economy.
