"There has been a huge surge in the interest in beer in recent years, driven by a move away from mass-produced, mass-marketed global brands to drinkers seeking out beers which are authentic, interesting, flavorsome and local," a spokesman told CNBC via email.
"With such a huge number of breweries in the U.K. producing a massively wide range of beer styles, it's no surprise people are really appreciating having a great choice of interesting beers, rather than a small handful of very similar beers dominating the market," the spokesman added.
CAMRA added that while beer was enjoying a surge in interest, 29 pubs – the bedrock of many communities across the country – were still closing every week.
Meanwhile, another finding from the report showed that 26 percent of young male drinkers aged between 18-24 preferred to drink their pint from a tankard, traditionally seen as the preserve of older, more discerning drinkers.
The lack of appetite for lager was having a broader impact on overall beer sales. Mintel said that Britons were estimated to have drunk 4.25 billion liters of beer in 2015, down from 4.27 billion in 2014.
There were "signs of growth" however, with value sales set to reach £18.1 billion ($26 billion) by 2020, up from an estimated £16.68 billion in 2015.
