The Sussex-based brewery took first place for its American Pale Ale in the Pale Ale category while the Long Man Best Bitter won in the Bitters up to 4% ABV category.
The brewery’s Long Man Long Blonde and its Long Man Old Man beers also achieved silver medals in the Golden Ales and the Olds and Milds categories respectively.
Head brewer Jamie Simm said: “We are immeasurably proud of the four awards we have achieved at this year’s World Beer Awards. It’s a great reward for the hard work that the production team put into creating consistently good beer.
“We’re not trying to reinvent the wheel when it comes to brewing, we are simply trying to create quality beers that we and other people like to drink.”
The brewery has achieved a total of 17 awards since it was first founded in 2012.
Based in Litlington, East Sussex, Long Man Brewery takes pride in its environmentally conscious ethos. Barley is grown on surrounding farm land and electricity is generated by solar panels, while waste products, such as water and spent grain, are re-used, composted or fed to livestock.
Duncan Ellis, director of Long Man Brewery and third generation farmer at the Church Farm base, said: “We believe that by looking after the land around us and sourcing everything we can from within the vicinity of our brewery, we can produce the very finest of Sussex ales as well as giving back to the land and community that we rely on to sustain our business.”
In 2014, the brewery teamed up with Eastbourne’s Curious Beer Club to produce Craft Pier, in an attempt to raise money following the town’s pier fire.
Up to £100,000 from beer sales were donated to support businesses affected by the fire.
The brewery has won a string of regional and national awards in the past, such as a bronze medal in the Best Bitters and Pale Ales category in this year’s SIBA South East Regional Awards and a silver medal at the International Beer Challenge in August 2015.
The company was also a finalist in the Sussex Small Business category at the Sussex Business Awards last year.
In 2015, Long Man also started exporting its products to Sweden and Finland, with further plans to export to other parts of Europe.
