I like goofy weird things - I'm not afraid to admit
I'm also not afraid to tell you that I love novel uses of things like liquid nitrogen. I'm just jealous I didn't think of this first! The brewers at Garage Project in New Zealand decided to play with using liquid nitrogen to separate "pure" lupulin from a bunch of Nelson Sauvin hops and then use that to produce their Hop # IPA. It's fairly novel and looks fairly straightforward.
To explain the process, they crafted a loving tribute to Breaking Bad.
