To brew this saison homebrew recipe, steep the milled roasted barley in 1 quart (0.95 L) cold water overnight. Filter through a sieve lined with a coffee filter. Mash at 159°F (71°C) for 60 minutes. Add the roasted barley extract to the wort at the start of the boil. Perform a 90 minute boil.
Chill to 68°F (20°C), transfer to a fermenter and pitch White Labs 670 yeast. If this blend is not available, pitch a Belgian saison strain (White Labs 565 or Wyeast 3724) along with Brettanomyces bruxellensis (Wyeast 5112 or White Labs 650). Hold fermentation close to 75°F (24°C).
After the initial wave of fermentation is complete, transfer to secondary with 1 oz (28 g) red wine soaked oak cubes and 25 oz (907 g) dried Zante currants. Store beer between 60-80°F (16-27°C) until the gravity is stable from one month to the next (a minimum of six months). Bottle or keg and carbonate to 2.4 volumes of CO2
