The hop growers in the biggest hop-producing area in the world are organised in the Hopfenpflanzerverband Hallertau e.V. - the Hop Growers' Association. The 'old' House of Hops was built during 1959/1960 by the Hopfenpflanzerverband Hallertau e.V. as the Association's headquarters. The cooperation is closely linked with the Verband deutscher Hopfenpflanzer e.V.. For example the management of both associations is in one hand.
Main task areas: foreign seasonal workers - hop supply contract - hop market regulation - representation and cooperation in the IHGC - sales promotion - market reports/crop assessment - organising events/public relations work - plant protection - advice for members - tax advice - legal advice - expertises/cases for compensation etc.
