It's now been a fair few months since changes to UK Duty legislation made it advantageous for breweries to produce beers at a strength of 3.4% or weaker, and we should be starting to see the effects of this at the bar counter as breweries seek to offer beers meeting this criteria.
Speculation at the time suggested that this could be the death knell for cask ales in the 3.5 to 3.7% range, with a host of new beer launches and reformulations of existing recipes hitting the market in order to comply. But to what extent has this actually happened?

Of course, it should be remembered that brewers do get some leeway with regards to deviation from the advertised strength. Cask ale, in particular, is a living, evolving, maturing product that can easily get stronger as it sits in a pub cellar. However, if breweries were to leave, say, a 3.8% beer unchanged and just write 3.4% on the pumpclip, they'd be cutting it very fine indeed, so by and large I'd expect them to be playing with a straight bat and brewing their revised beers 'down the middle' rather than trying taking unnecessary risks trying to get away with something that lurks in the margins. And, theoretically, a weaker beer should be cheaper for them to produce too, though this isn't always the case.
3.4% is something of an iconic ABV in certain quarters, mainly because of Brakspear's Bitter. Back when I was a youngster, before the brewery closed, this was considered an absolute classic session beer, and proof that great things can be done at this sort of strength.
