Edinburgh brewery Vault City has brought back its “Buckfast-inspired” sour beer, after selling 7,000 litres of its first release.

The fast-expanding brewery noted its new release, known as “Black Grape Buckie V.2”, is available to buy online.

Vault City said: “Paying homage to the iconic Scottish tonic wine, this brew is packed with the familiar, nostalgic flavours of sweet stewed fruits, a hint of cough medicine, and the juicy twist of black grapes.”

It described the Buckfast-inspired beer as a "crowd favourite".

Vault City co-founder Steven Smith Hay said: “We wanted to create a drink that wasn’t just a beer - it’s a cultural phenomenon in a can.

“We are thrilled about the reception to our Buckfast-inspired brew. Having sold the equivalent of 15k cans of this first release, we couldn’t ignore the demand.”

He added: “We are proud to bring a taste of Scottish culture to customers far afield and to cater to those looking for more accessible, funky flavours of sour beer.”

Vault City noted that it had, a few weeks ago, released the DDF Caterpillar Cake Imperial Stout, which it described as “an ode to Scotland’s sacred deep-frying heritage”.

The brewer has also describe this beer as “a decadent deep-fried cake stout inspired by the birthday delicacy”.

It noted that its beers are now available in more than 20 countries and at in excess of 250 bars.

Vault City observed it had also moved to “embrace a four-day working week”, and pledged to pay staff the London living wage of £13.15 per hour instead of the real living wage of £12 per hour.

The brewery said: “With the recent purchase of a new brewery that can churn out over 10 million litres of beer annually, Vault City is set to become a household name.”

In the supermarket sector, Vault City’s beers are stocked in Tesco, Morrisons, Sainsbury’s, and Waitrose.
