Changes

Iris is different than [[Lambic]]. It is only made with malt of the pale ale type (giving a more amber color to the beer) conserves the typical flavor of the spontaneous fermentation, the complex aromas , and the vinous taste. The hopping is different too. Lambic is made with 100% aged hops, for the Iris they use 50% of aged hops and 50% of fresh (dried, not wet) 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 dry hopping with fresh (dried, not wet) hops in a linen bag for two weeks before the bottling. This "cold hopping" (or dry hopping) gives the beer a more intense flavor and makes the smell and the taste more bitter.
