Project motivation:

Climate change, especially the lack of moisture, is reducing hop yields in the Czech Republic. Therefore, growing areas that have the possibility of irrigation are at an advantage, but its use is often limited by a ban on water abstraction from small water sources. Where there is no irrigation at all, hop growing areas may soon disappear, and even cease to be used for agricultural purposes. This problem should be solved by planting hop fields with drought-resistant hop varieties or genotypes.

Drought-resistant hop varieties will increase efficiency and productivity, and thus competitiveness on the Czech and global markets.

Project objectives:

  1. To maintain the competitiveness of Czech hops on the Czech and foreign markets.
  2. To maintain hop growing areas even in regions with low rainfall.

How to ensure project goals?

  1. Obtaining new drought-resistant hop genotypes
  2. Registering these varieties
  3. Developing a methodology for growing new hop varieties in arid regions
  4. Applying these varieties in cultivation and brewing practices

Česká pivní vize

The Czech Beer Vision tasting competition includes a special category: Implementation of new raw materials and technologies in brewing. Czech Beer Vision includes a special category focused on innovation in brewing, which is currently dedicated to beers hopped with new varieties of drought-tolerant hops – known as Odolchmely.

 

These modern varieties include Saaz Shine, Saaz Comfort, Juno, Uran, Ceres, and Saturn. The category was created in cooperation with the Hop Research Institute in Žatec as part of research project QK21010136 of the Ministry of Agriculture of the Czech Republic.
