"The hopping is different too. Lambic is made with 100% dried hops, for the Iris we use 50% of dried hops and 50% of fresh hops. The latter cause a superb acidity, the former, due to their tannins, enable to conserve the beer while preserving all its qualities.

After two years in the barrel, the Iris undergoes a second fresh hopping two weeks before the bottling. A linen bag, filled with hops, is soaked in the beer for two weeks. This technique, called "cold hopping", gives the beer a more intense savour and makes the smell and the taste more bitter."

My guess would be that the varietal is some noble hop, hallertauer perhaps, and that they are dipping into their 3-year aged supply for the "50% dry hops."

Mmm, La Folie -- wish I had some.

Cheers!

-still curious about what "Cantillion Hops" are supposed to represent.

The fresh hop used in the Cantillon Iris is "Styrian Goldings". I hope that helps!

It is interesting how much proprietal information M. van Roy posts on his webpage -- it seems he wants to enourage people to copy him!
