Thanks that's really interesting. An awful lot of commercial beer over here, especially cask beer, is in the 3.8 to 4.5% range. A lot of that beer is very similar, either just base malt, or base malt plus crystal, and then either English or American hops or both, and an English yeast that is relatively neutral. I'm a big fan of mixing English hops with American. Complexity!
But here in Manchester there is a very healthy 'craft beer' scene with lots of small breweries that are copying the American model, in every way - the staff have bushy beards and lumberjack shirts and try to disguise their Northern English accents. Ha ha. Some very good beer being made though. And some not so good. And a growing variety. More and more keg beer, cask is less fashionable especially with the younger beer afficianados. All strengths and beer styles are available. It's healthy and I have never had it so good. I rarely drink pints now either! Mostly 2/3 pints (13oz/378ml), which is widely available here now in Manchester. Which is a similar amount to your measures I think? It's a significant change really, pints are still the norm but smaller measures are becoming fashionable.
