The report says 2014 volumes for the total UK beer market will hit an estimated 4.2 billion litres, an increase of 1.3%.
It says the biggest increase will come from lager, with a rise of 1.7% to 3.2 billion litres, with ale registering an increase of just 6 million litres to 891 million litres.
Stout is in decline with estimates for the year-end at 183 million litres.
Senior drinks analyst Chris Wisson said: “While much of the market’s recent value growth has been driven by inflation and then now-defunct beer tax escalator, successive 1p cuts on the tax on pints and the slowdown in the cider market, bode well for beer’s improving fortunes.”
Mintel said that one in five Brits have drunk craft beer in the past six months, with the figure rising to 31% for 25-34s.
But the research also found that 36% of drinkers are unsure what the term “craft” actually means.
