Toast Ale has teamed up with Warburtons to unveil the UK’s first ever beer brewed with leftover crumpets.

Each bottle is reportedly packed full of crumpets and the beer has an alcohol content of 4.2%.

The Session IPA was brewed by Toast Ale with Warburtons crumpets that “didn’t quite make the cut”, but were the perfect ingredient for producing a beer, according to the brewer.

Toast Ale replaced some of the malted barley in the beer with crumpets, extracting starches and sugars and breaking them down into fermentable sugars.

James King, marketing and brand manager at Toast Ale said: “Our mission remains to brew beer that is planet-saving and palate-pleasing, and we couldn’t be more excited to venture into the world of crumpets.  As a British staple, they bring something hole-y different than our bread brewed beer, with a unique taste. We will continue to toast change and hope everyone loves this new Crumpet Beer as much as we’ve loved brewing and tasting it!”

Darren Littler, head of product Innovation at Warburtons, said: “We’re thrilled to announce an innovative way of utilising our ‘wonky’ products whilst celebrating the nation’s love of crumpets in a whole new way. Not only are we proud that Crumpet Beer is our first non-baked product we’ve ever launched, there’s nothing ‘butter’ than this cold brew teamed with a plate of warm crumpets!”

Toast Ale has partnered with Waitrose to launch the limited-edition Warburtons X Toast Ale Crumpet Beer. It can also be purchased from the brewer’s website for £28 for 12 x 30cl bottles.
