Tsujigiri, which also features yuzu to add citrus character, is brewed with Sorachi Ace and Chinook hops, the latter used to complement the sake yeast.

The brewery, which enlisted Dean Pugh, general manager at the Shepherd’s Bush branch of BrewDog, launched the beer at the end of May.

They explained on their blog: “The aim and the result: an easy drinking I.P.A with a considerable twist! Speaking of twists, the name of the beer, which is obviously Japanese, can get you a little tongue-tied.

“Tsujigiri literally translates as “crossroads killing” and describes the impulsive act of a Samurai testing out his new sword on a random individual or passer-by. Not too far removed from an ‘impulse brew’.

“It is not your everyday I.P.A but can be surprisingly drunk like one. The beer comes to 6.2% and on the nose, it’s citrussy because of the yuzu.

“It also has a subtly herbal aroma with a fresh minty-ness from the Sorachi Ace. Sipping on the beer, you get the I.P.A bitterness through the tangy lemon and fresh herbs, but it rounds off really refreshingly and balanced. It’s bang on for the summer and a delight to drink.”
