Tiny Rebel was founded in Newport in 2012 by brothers-in-law Bradley Cummings and Gazz Williams. Gazz had learned to homebrew with his grandfather, and introduced his friend Brad to the hobby. After brewing in Brad''s father''s garage for a number of years, the pair decided to make their hobby their profession. They rented an industrial unit in Newport. The neighbouring unit was quickly needed, and the brewery expanded into it a year after opening
The company opened their first bar in Cardiff in late 2013, after winning the top three places at the Champion Beer of Wales competition. Urban Tap House was the first dedicated craft beer bar in the city, and a branch opened in the company''s hometown of Newport in 2015. The Urban Tap House brand was retired in 2016, with the bars being renamed Tiny Rebel. 2015 marked winning Champion beer of Britain at the Great British Beer Festival in London, the youngest and only Welsh Brewery to achieve this accolade.
