Caption: Head Brewers Chad (Crooked Stave) and Matt (Hawkshead)
What started as a way of bringing brewers in the UK together in 2013 to challenge one another to push creativity to the limits has not only been successful but has since grown and developed with this year's project going trans-Atlantic - the 7 UK breweries have been teamed with 7 of the best from the USA.
We had the great fortune of being paired with Crooked Stave Artisan Beer Project, specialists in the art of brewing with wild yeast. Head Brewer Chad Yakobson is one of the most respected and highly sought after experts in the field of brewing with Brettanomyces in the world.
Drawing the colour green, together Matt and Chad decided to create a beer that nobody would expect from either head brewer. Both wanting to play to each other's strengths, thoughts of using the kettle souring technique Matt had been working on came to mind. This soon turned into a brew which would include lime, lemongrass, lactose and hops.
Brewing together back in May, Matt and Chad created their take on Key Lime Pie - biscuity, spicy, sweet flavours with the sharp zestiness of lime. Following the success of the initial brew, it was decided that Chad would recreate the beer back at Crooked Stave, thus resulting in two ‘pies’.
Born on both sides of the Atlantic is Key Lime Tau (2π) Tau mathematically being 2 x Pi (τ = 2π).
Key Lime Tau (2π) and the 6 other rainbow beers will be released on draught at special launch events at Magic Rock Tap , Huddersfield and Beavertown Tap Room, London on Saturday 19th September (check out our What's On page). A limited edition mixed case of all 7 bottled beers along with a branded glass will be available to purchase too.
Alongside the official launches we'll be showcasing Key Lime Tau (2π) at The Beer Hall on the 19th from 12pm.
We're excited to see what the other pairings have created - there are no set boundaries to what can be brewed or how the colours are interpreted. Here's to 2015's Rainbow Project being even bigger and better than ever before!
