From BrewDog : 

With DIY Dog, Brewdog wanted to do something that has never been done before as well as paying tribute to their home-brewing roots. They wanted to take all of their recipes, every single last one, and give them all away for free, to the amazing global home-brewing community. The recipe packs have been made to the specifications of the DIY Dog recipe. *Please note, these 5 gallon kits are intended for all-grain brewing. They are designed for use by experienced homebrewers with a kit set up according to all grain brewing methods.”

Interesting to me to see the impact open source has made on home brewing!

As soon as I can justify buying a grainfather I will try one of their kits.
