One of my favorites.
"Our Spring Saison is light blonde in color with a fresh hoppiness and a wild and rustic Brettanomyces character. Lighter in color and alcohol than our Saison Rue, yet equally complex in its own way. Perfect for warmer weather and Spring celebrations.
ABV: 6.5%, IBU: 35, SRM: 4, Release: March - May"
I bet the recipe is pretty simple, OG low 1.050s mostly pils (maybe some flaked wheat), mashed on the cool side to ensure good attenuation. 35 IBUs with some late additions of American nobels (Crystal, Sterling, Mt. Hood or whatever), ferment with a saison strain plus Brett C. If you want to get close I would pitch the dregs from a couple bottles to get their Brett strain. You could even add a small dry hop after letting it funk for a couple months.
Might not be perfect on your first try, but it should be tasty.
