Drought affects Pilsner Brewers' prized Czech Hops

After a brutal summer, the growers of aromatic 'Czech Saaz' hops that are used in Pilsner Lagers around the world are looking for new varieties and irrigation methods to boost their faltering harvests.

Jiri Smetana of the Hops Growers Union of the Czech Republic said that this year's rainfall was 60% lower than normal and temperatures of up to 40 degrees Celsius (104 Fahrenheit) were record highs, which damaged crops.

Smetana, at a hopyard in Steknik, near Zatec (whose German name is Saaz), said that this season had been extremely hot and dry.

He said that "we expect a decline in the yield of 25% to 30% compared with the long-term mean" for Saaz.

The crop is less potent and less bitter

Smetana stated that the average total harvest is 6,500 tons. This year, however, farmers will be "happy" if they get a 5.

Brewers had to 'use more' of the reduced output because it was less bitter and potent.

Smetana stated that the breweries would be able cope with the situation due to pre-stocking. However, a poor harvest in 2013 could cause serious problems.

Around 80% of Czech hops is exported. China is the largest market, followed by Japan.

The Saaz Shine, which is able to withstand dry climates, is a popular experimental variety. It is only being grown in a limited area, but growers hope it will take off.

This year was a real test for the?varieties. Smetana stated that we will be able to see how the drought resistance works, but for now, the plantation looks good.

The problem is that Saaz has become a tradition for many customers. Japanese and 'Chinese customers, who are the main export customers for Czech Hops, view new varieties with some suspicion."

According to the latest estimates, growers are building small reservoirs near plantations and placing their hopes in plans for a "major" new dam that will not be completed for 15 years.

Saaz will also be fine-tuned for temperature and drought resistance and genetic modification.
