These beers are part of a collaborative process that Partizan have been working on with The Kernel Brewery, just down the road from them in Bermondsey. Back in the summer of 2015, they created a wort - The Kernel trucked the first runnings (high-gravity, sugar-rich) down to Partizan's brewhouse which they used to brew a high-alcohol Quad. The guys at the Kernel then used the (weaker, lower-gravity) second runnings to create a lower alcohol, mixed fermentation Saison, subsequently aged in oak foudres. The concept is that by sharing the base mash for two very different style beers the finished beers could then be reunited in the glass to create a fascinating drinking experience.
