For me the point about session beer is that it is pretty vague, it suggests a certain approach to a day enjoying the pleasure of beer rather than your day job which might well be worrying about fractions of percentages. I'll concede you might be a bit cross if you ask for a session beer in a pub and they want a tenner off you on producing a pint of some sort of triple imperial rocket fuel. In the end though it's a legal requirement to show the alcohol content of drinks served - and it's that you should be relying on rather than a bit of ethereal nomenclature - assuming you believe the label of course. If you can't work out that a 7% beer is going to get you more drunk if you throw multiple pints of it down your neck in a short space of time than a 3.7% beer would, you probably shouldn't be drinking at all. Similarly if a pub put up a list of 'session beers' on a chalk board that weighed in at six or seven percent they'd not exactly do their credibility much good but, rather like asking for a session beer without clarifying the abv first, I think that's pretty unlikely.
|Beer. Friends. Session.|
And now? The sun is trying to shine, and I think a beer and a session of quiet contemplation and conversation beckons. With the right approach any beer can be a session beer (to misquote Aleheads), if beer's just a route to getting hammered, none of them are.
* Yes, it's a generalisation and I'm sure there are exceptions!
