Customers joined Castle Rock Brewery, Nottinghamshire Wildlife Trust and Murphy & Son for the launch of their collab beer ‘Ripples’ last Thursday, raising just shy of £1,000 for the Trust’s current Wetlands for Wildlife in Nottinghamshire appeal. The appeal aims to raise at least £45,000 to support its efforts to reverse the decline of the county’s vital wetlands.
Castle Rock and Nottinghamshire Wildlife Trust have a friendship that has spanned over twenty years, during which time the brewery has created over 155 unique beers for the Trust, helping to raise over £130,000. More recently, local supplier to the brewing industry Murphy & Son have also partnered with the Trust, as part of their efforts to reduce their emissions to net zero and help wildlife along the way.
The three organisations brewed ‘Ripples’ together, with the intention of creating a cleaner, more sustainable beer. Murphy & Son worked with Castle Rock’s Pilot Project brewer to provide technical support with ingredients, process aids and optimisation, enabling maximum efficiency and minimum wastage while making an amazingly tasty beer.
The beer was brewed with Kveik yeast, a Norwegian strain which is rapidly building a reputation among brewers for all the right reasons. It ferments at a higher temperature, meaning less energy is used to cool the beer as it spends significantly less time in tank. The golden ale also used UK hops, lending a traditional aroma and crisp, dry bitterness while also ensuring a lower carbon footprint opposed to styles using international hops often shipped from New Zealand or the US.
