Moonshine Drinks has launched a patented bag that allows drinkers to make 25 pints of beer simply by adding water amidst claims home brewing is the fastest growing hobby in the UK.

Home brewing has made a comeback in the UK over the last five years, the company claims, due to the recession and high beer prices in pubs, spurring it to launch its kits – pictured, recommended retail price £25 ($40.50) – into 140 UK retail outlets including Lakeland and The Garden Centre Group.

A team of brewers and engineers – including experts from the University of Nottingham and Nottingham Trent University – spent two years creating a single-use kit with a low-cost non-return valve, which will provide 25 pints inside 14 days, with the beer then keeping for a month.
