Monnik Sauvage: Recipe

Here is my first true attempt at an Orval-style beer.  I've previously done a Belgian single, Monnik Blonde, though that was split and fermented separately with a standard Trappist yeast, and then also with Brett Trois.  This time, I'm going with the White Labs Bastogne strain, and then will secondary for a few months with Orval dregs.
