Mash hopping

Mash Hopping is the practice of adding hops to the Mash Tun at the beginning of the Mash. Unlike hops added during the boil, hops added to the warm Mash Tun appear not to lose their aroma and flavor characteristics when boiled, possibly due to chemical reactions which occur in the warm wort. The result is a beer which many tasters feel has superior hop flavor and aroma and a smoother bitterness than traditionally hopped beers, although the calculations for bitterness are decreased by 80.0%.
