North London’s Beavertown has added a straight up 6.7% IPA to its portfolio of beers, more than four beers after opening.

The brewery explained that previous collaborations with other breweries and its earlier wave of beers, ‘The Invasion Of The Lupuloids’ has enabled Beavertown to understand the exact form its IPA would take.

They said: “First came the collaborations. We learned so much valuable information, and are eternally grateful to everybody who came to visit / opened their doors to us. These helped create fantastic brews in order to solidify in our minds exactly what we wanted our IPA to be.

“Then we turned it over to you, and introduced “The Invasion Of The Lupuloids,” as a series of waves of beers accompanied by a list of every technical detail you could want and more – by way of something similar to Top Trumps cards – every thing from yeast strains, through original / final gravity, to total hop oils per 100g listed.

“We felt this gave people ample info to make an informed decision, and then we listened. As feedback came in we tweaked recipes and plotted new brews, releasing another wave with the same info available, and then repeated the process.

“The end result was 10 IPAs, that were tweaked and adapted with the feedback we received until we were able to bring you the LUPULOID.”
