The Hallertau or Holledau is an area in Bavaria, Germany. With an area of 178 km², it is listed as the largest continuous hop-planting area in the world. According to the International Hop Growing Convention, Germany produces roughly one third of the world's hops (used as flavoring and stabilizers during beer brewing), over 80% of which are grown in the Hallertau.
Hallertau is roughly located between the cities of Ingolstadt, Kelheim, Landshut, Moosburg, Freising and Schrobenhausen. The region is defined by the hop-planting area in Bavaria. It is divided into several seal districts:
- Au in der Hallertau
