The noble Lager hop. From the Zatec area of Bohemia, traditional variety with a long, long history. Small to medium dark green cones with low Alpha levels, delivering sweetly floral, grass, wood, earthy and mint aromas, maybe some cinnamon too.
Used across all the notable Czech Pilsners and helps define that beer style. Similarly suits and is widely used Continental-style Pilseners, Helles & American Light, Bock lagers and lighter Ales.
