Say goodbye to dry July and hello to IPA Day, held worldwide on Thursday August 1.

To celebrate, local brewery Mismatch has teamed up with some of the best bars in the west end to create a one-off west coast black IPA – called Westies IPA – with proceeds going to food rescue charity OzHarvest. The beer will be on tap at Bank Street Social, Clever Little Tailor, Cry Baby, Hains & Co, Malt & Juniper, Maybe Mae, Udaberri and Alfred’s Bar from Thursday until sold out.

With the continued success of the craft beer industry, events such as IPA Day serve as the perfect opportunity to experiment and make limited-release beers. But the Mismatch team wanted to take this one step further, inspired by worldwide fundraiser Negroni Week.

“We really like the concept of Negroni Week – boozemakers, venues and punters all enjoying that delicious drink all for a cause close to their hearts,” Mismatch co-owner Marc Huber tells Broadsheet. “I’d really like to turn IPA Day into something like that. Breweries across the country coming together with venues and consumers to create a day, or week, to raise funds for local communities and charities.”

The IPA dates back to 18th-century England, but its more recent history lies on the west coast of America (the region’s hoppier style – more bitter than its east coast, or New England, IPA counterpart – is what most people think of when they think of IPAs). It was only fitting, then, that the participating venues all hail from the west end.

“I actually really like how all the west end bars have created a bit of community and get along,” says Huber. “We thought these bars would work well together and could really pull a crowd to support the event and OzHarvest.”.

The Mismatch team considered experimenting with native herbs, but recognised that could result in a polarising drink. So they focused on making something that is delicious, sessionable and true to a traditional west coast IPA. The Westies IPA is a mix of “old and new school”, says Mismatch head brewer Ewan Brewerton. “The hops used [are] a combination of cascade, centennial and chinook in the dry hop, and a decent dose of NZ Waimea Hop Hash in the whirlpool.”

The result is a dry, hops-forward beer with supporting bitterness and a dark, reddish hue fitting for the time of year. “All in all it’s delicious and has been created by a crew that lives and breathes great booze,” adds Brewerton.

The beer will be extremely limited, with less than 100 kegs (split between the bars and Lot 100) available while stock lasts. Find it at Bank Street Social, Clever Little Tailor, Cry Baby, Hains & Co, Malt & Juniper, Maybe Mae, Udaberri and Alfred’s Bar from August 1.
