I did not try the Glassade, but I made a big Maibock (10 gallons) using 25 pounds of pilsner malt, 1.5 lbs of Munich, 1 pound of Carahelles, and 1 pound of Carafoam; Hallertau hops (3 oz at 60 min, 1 oz at 20 min, and 1 oz at knockout). Pitched a full 5 gallon batch's cake of WLP 800.
I haven't tried it yet - it has a couple months to go.
Cheers.
