Mycotoxins are a diverse range of molecules that are harmful to humans. They are secondary metabolites secreted by moulds, mostly Penicillium and Fusarium. Because of their antimicrobial activity it is most unlikely that hops could be considered a source for mycotoxins. In order to confirm this we again monitored the situation concerning residues of most toxic mycotoxins by screening hops after the last harvest. In our investigations, all major European varieties from different growing areas were considered. To guarantee a representative analysis, ten samples of large lots were selected and then combined into one composite sample for each variety. These results for the 2010 crop are presented in the table below.

Downstream products, such as regular iso extract, rhohydro-iso-, terahydro-iso- and hexahydro-iso extracts, are usually dosed prior to filtration. However in practice some brewers are still adding these extracts after filtration, when there is a distinct risk of precipitation in beer and therefore also of inducing gushing.

Each crop year we like to show the annual variability in the contribution of hop oils to beer flavour. The representative hop aroma substance chosen as a marker is linalool, which has been shown to correlate well with the sensory impression of a hoppy aroma in beer.

The Hopsteiner Guidelines 2010 will soon be published and be available at BRAU 2010 in Nuremberg. We are still working on some details of the beer production and will present the balance of World Alpha Acid Supply and Demand as soon as possible.

Light Stable Kettle Extract (LSKE) can be used to brew beers in much the same way as beers produced using conventional CO2-Extract.

In the hop garden portrayed on the left hand side (growing Perle), no re-training was carried out after the hail storm due to little time and a lack of man power and time. One can see quite clearly that only very few laterals have reached the top of the wire of

The official German 2010 hop crop estimates were published on August 26th. Following please find those estimates as well as the final world

Mid-year acreage estimates for all major hop growing countries have been published. After the 13.4% acreage increase from 2007 to 2008 there has now been a decrease of at least 11.6% for crop 2010. The largest decreases have occurred in USA and China, and the decrease in the PRC could in fact be larger than published. Overall the decrease takes worldwide hop acreage back to its 2007 level, which at the time did not supply enough alpha to meet demand. In the meantime variables have changed so short-term supply should be adequate. ...
