A selection of the most exciting breweries from the UK and USA have teamed up to produce seven of the most hotly-anticipated collaborations to ever grace the UK craft landscape. We’re delighted to be partnering with Siren Craft Brew and the Rainbow Project to get those innovative brews into the hands of beer lovers around the UK.

Wild Beer Co x Side Project

Rosa Rouge 5.0%

A sour saison with pomegranate and rose petals, Rosa Rouge pairs the wild yeasts of Missouri with Somerset beasties for a co-fermented, barrel aged sour saison. A funky mixture of microbes in burgundy wine barrels lends a tart acidity and farmhouse slant while the fragrant rose and pomegranate play with the woody tannins.

Hawkshead x Modern Times

Yellow 5.3%

A mixed culture barrel aged saison with apricots brewed in San Diego. Fermented with Modern Times’ house wild yeast and a wildly foraged yeast found on loganberries (a blackberry and raspberry hybrid) this transatlantic collaboration was then rested in red wine barrels before going through a secondary fermentation on over 3 lbs/gallon of Southern California apricots.


Lapis Lazuli 8.2%

A sour ale inspired by ancient Egypt. Beavertown drew inspiration from natural winemaking to produce an amphora and barrel aged beer. For a fruit addition they used Pinot Noir grape must from Forty Hall vineyards in North London. The beer was then fermented with a sour mix featuring a range of wild yeasts and bacteria, before being aged on pinot noir grape skins for eight months.

Magic Rock x Casita Cervecería

Papillon 7.5%

Magic Rock’s Indigo release comes in the form of a barrel aged sour ale with blueberry, apricot and butterfly pea flowers. The foundation of this finale comes in the form of beautiful French oak barrels. Atop of the base beer fermented in the barrels with a mixed wild yeast culture butterfly pea flowers were used to introduce colour. To add a fruity depth, blueberry and apricot concentrate were added.

Burning Sky x Three Floyds

Out from the Void 11%

Burning Sky’s second collaboration with Indiana beer legends Three Floyds comes in the form of a barrel aged barley wine. Fermented with Burning Sky’s house ale yeast and a Brettanomyces strain the beer was then ages sauternes wine barrels with vanilla pods and cacao nibs to give a decadent chocolate orange flavour.

Partizan x New Belgium

Phoenix 5%

A continuation of last year’s theme of destruction and regrowth, Phoenix is a “green” inspired wood aged saison that takes full advantage of the unique character of aged hops. Partizan’s aim was to showcase the flavours drawn from older hops and the barrel in the purest way possible, deciding against spirit barrels and mixed cultures in an effort to bring the nuanced flavours to the fore and retain a “greenness” to the beer.

Siren x Sante Adairius

Equilibrium 5.8%

Equilibrium is a red wine barrel fermented saison. This year Siren wanted to create a concept to link up with their previous release, the “blue” themed Santo del Frio. In order to get to violet, they blended that beer with something hot. A red-inspired, warm-pitched, red wine barrel fermented saison.
