To brew a rye saison, you'll need to incorporate rye malt into your grain bill. Rye malt adds a distinctive spicy and earthy character to the beer, complementing the fruity and spicy flavors typical of saisons. Replace a portion of your base malt (usually Pilsner malt) with rye malt, usually around 10-20% of the total grain bill. Follow your usual saison brewing techniques, paying attention to mash temperature and time, proper yeast selection, and fermentation temperature control.
