But for this new beer, called No Label, BrewDog worked with a hop farmer to obtain Jester hops – a variety naturally prone to altering sex whilst growing – and brewed No Label with hops that have undergone this change and grown male flowers.

The brewers say it was important to incorporate these hops into the brewing process to add diversity, rather than discard them.

The beer will go on sale tomorrow at the opening night of BrewDog’s latest venue in London.

Profits from the beer will go to Queerest of the Queer, an LGBT organisation which aims to celebrate the diversity and talent of LGBT Londoners.

James Watt, BrewDog co-founder, said: “No Label is a new level of innovation in beer, smashing stereotypes surrounding the brewing process and using hops discarded by the brewing industry due to their ‘gender issues’.

“Producing this non-binary, post-gender beer has been a long and careful process and we’re sure that many so-called beer purists will question its legitimacy; but we care more about freedom than labels. Diversity makes everyone and everything richer.”

The Scottish brewery has come under some criticism from some members of the trans community, accusing them of ‘cashing in on our troubles.’

Before the winter Olympics, Brewdog launched an anti-Putin beer called Hello my name is Vladimir: “http://gcn.ie/news/brewdog-launches-protest-beer-putin/
