Wallace, famed for writing several bestsellers and presenting the XFM breakfast show, decided to create the beer to celebrate the release of his latest book.
The IPA is Tom Ditto after the central character in Wallace’s latest book, a comedic novel called Who is Tom Ditto?
“It’s sweet, it’s bitter, it’s golden and like the book its heart is in London and New York,” said Wallace on his blog.
“It even features a new experimental hop that they’ve just decided to name Wallex. I feel like David Attenborough discovering a bug.”
The beer is released next month.
Historic London brewery Truman’s reopened in Hackney in September 2013, 24 years after its original Brick Lane brewery shut down.
The new 10,000 sq ft brewery is called the Eyrie, the term for an eagle’s roost, and kicked off production with two core beers – Truman’s Runner, a best bitter, and Truman’s Swift, a golden ale.
Wallace, whose book The Yes Man was adapted into a film starring Jim Carey, hailed the brewery as “legendary” and added: “I have done my best to brew the greatest beer of all time, which I fully intend to enter into the Booker Prize next year.”
