The beer, which is launched this Friday (26 February), is 9.2% and features Citra, Mosaic and Simcoe hops.
The brewery explained: “Modern, pale, hop-forward beers are very much our thing. We also love challenging beers with higher alcohol, complex fermentations and demonstrable skill in their construction.
“A Double IPA has been a dream of ours for some time, one that remained within reach but outside of our grasp, until now.
“We only attempted to brew our first Double IPA when we were absolutely certain that we had the experience, technical ability and confidence to do so.
“We also needed hops – lots of hops, no less than 50kg in a 4000l batch, in fact – and 55|01 uses three of our absolute favourites: Citra, Mosaic and Simcoe.”
The beer has a pale malt grist, while hop additions make for a “symphony of juicy tropical fruit, resinous pine, aromatic zest and slick, citric bitterness” that remains both clean and balanced.
They added: “55|01 satisfyingly pulls off the Double IPA trick of being both intense and drinkable, balancing its flavours and textures even as it crosses your palate.
“It’s a beer that marks a level of advancement for us as a brewery.”
