In January 2024, co-founder of Thornbridge Brewery, Simon Webster received an email from Garrett Oliver. He’d heard a rumour that Carlsberg Britvic, the now owners of Marston’s Brewery in Burton-upon-Trent, were “laying the union to rest.” The Brooklyn brewmaster continued to ask Simon if he’d be interested in taking a set, in turn saving it from being permanently erased from British brewing history.

Six months later, after Simon and Thornbridge’s brewing director Rob Lovatt had visited Burton to assess the situation, a single Union set was delivered to their brewery in Bakewell, Derbyshire. In the months since, it has become a focal point for their brewery, and something that has stirred plenty of excitement in the process. This has no doubt been assisted by the fact it’s been used to produce some exciting collaborations, including with the likes of The Kernel and Odell Brewing. They’ve even produced a Strong Dark Mild with Garrett himself, a beer that would go on to become award-winning.

In October 2025, host Matthew Curtis was invited to spend two days at Thornbridge and document a collaboration on the union system with Theakston Brewery of Masham, North Yorkshire. As the brewers set about making a version of the Yorkshire brewery’s famous Masham Ale, Matthew set about filming, interviewing and documenting as much as he possibly could. The idea was to get to the heart of why the arrival of the Burton union at Thornbridge felt so significant.

In this documentary-style episode of the Pellicle Podcast, you’ll hear from several people at Thornbridge, including Simon Webster, Rob Lovatt, brewing manager Dominic Driscoll, and several others, plus Theakston’s head brewer, Mark Slater. With plenty of analysis throughout, plus an original soundtrack composed by the host himself, this is the story of how Thornbridge saved the Burton Union.
