The Good Beer Co. has a new cause. Last night at Collective Kitchen it launched Love², a beer supporting the “Yes” campaign during the ongoing marriage equality postal vote.

It’s the long-awaited second brew from the Brisbane-based social enterprise, after last year’s immensely popular Great Barrier Beer raised $25,000 (and counting) for the Australian Marine Conservation Foundation.

The idea behind The Good Beer Co. is simple: match one brewery (Victoria’s Bright Brewery in the case of Love²) with one charity partner (Australian Marriage Equality’s “Yes” campaign, this time) with company founder James Grugeon and his team in the middle mobilising an audience. With Great Barrier Beer, profits were split 50-50 with the AMCF. This year, though, all profits from the beer will be donated to AME to help with its campaign to legalise gay marriage.

“We’re socially minded, we think it’s a really big social issue in Australia and we want to support our friends in the LGBTI community,” Grugeon told Broadsheet.

Love² will be available on tap at venues across the country, and this week rolls through a bunch of different Brisbane bars including Newstead Brewing in Milton tonight; Newstead Brewing on Doggett Street tomorrow night; The Mill on Constance on Saturday night; and Oxford Taphouse on Sunday.

James Davidson from Bright Brewery describes the mid-strength beer as “nice and easy and friendly – perfect for sharing with mates.”

Davidson says Bright Brewery was keen to work with The Good Beer Co. after collaborating with Grugeon at February’s Sustainable Living Festival in Melbourne. “We’ve been having conversations about what we can do together,” he says.

After the postal survey was announced in September, a friendly catch-up in Bright saw the idea developed for a beer as a fundraiser for marriage equality. Less than a month later, Love² was born.

Eighteen months on from the Great Barrier Beer campaign, Grugeon says The Good Beer Co. is older, wiser and has better relationships with charities and business partners. “We are relaunching Great Barrier Beer with a new charity partner before Christmas,” he says.

He reckons a bigger presence on social media and loyal followers will see future campaigns grow in reach. “This time next year we will have a range of five beers, of which Great Barrier Beer and Love² will be two,” Grugeon says.

Bottles of Love² can be pre-ordered ahead of their release on October 30, while kegs are available from today. Even after the postal vote’s outcome is announced on November 15, Grugeon is planning to continue supporting the marriage equality cause – “We’re very keen to roll the beer out after the vote” – by being the go-to brew for celebrations such as same-sex weddings.

Correction: the original story stated that profits from Love² would be split 50-50 with AME. In fact, all profits from the beer will be donated to AME. The story has been updated to reflect this.
