Had a search, and couldn't see this anywhere - it has only just been released! Anyway, Brewdog have published a recipe book for their beers. For Free as a PDF download. https://www.brewdog.com/diydog Had a quick look, it looks in depth - might try and sneak it onto work printers at some point, but it's definitely getting saved to my phone. I have been critical of BrewDog in the past, but this is very cool.
