They pasteurize, you’re not getting anything.
Their yeast is very similar to the Dekoninck yeast, if not the same. You can get it from Omega through Northern Brewer, Midwest Supplies (it’s a pro strain) as Belgian Ale DK, or WLP515 from White Labs (vault) or 3655 Belgian Schelde from Wyeast (spring seasonal), although that might be slightly different, very close though.
