Glycosidically bound hop polyphenols of the native hard resin fraction and their occurence in hops, hop products, and beer

Research and development | The beer bittering potential of hops apart from iso-alpha-acids can be assigned to phenolic compounds of the native hard resin fraction. Based on taste re-engineering experiments, Dresel et al. demonstrated that the additive contribution of iso-alpha-acids and various isolated hard resin components is necessary for constructing the authentic bitter percept of beer [1].

"Hop creep" - soon more predictable?

Technical Support | The hop creep phenomenon is caused by the introduction of diastatic enzymes via dry hopping. Such hop enzymes are converting unfermentable real extract into fermentable sugars. In the presence of active yeast this may lead to unwanted secondary fermentation of beer followed by uncontrolled increase in diacetyl, alcohol, and carbon dioxide.

Update on EBC methods related to craft beer

Technical support | When compared to regular hop addition during wort boiling, late and especially dry hopping make the composition of beer more complex and diverse, which requires additional analytical methods. For this purpose, two new methods are now recommended by the European Brewery Convention (EBC). At the same time, the precision values given for BU (Bitterness Units) measurement have been updated. They now cover also higher ranges as typical to dry-hopped beer.
