Archer hops are a relation of Cascade which can be used. A step mash is used to extract all the sugars from the Malts. I use two packets of dry yeast, Mangrove Jack's M31 Tripel and Lallemand Abbaye Ale yeast to make sure of full attenuation. I lightly hopped this brew, as I think Belgian Ale is about Malts and Yeast.
