Nils Rettberg from VLB Berlin new reviewer for BrewingScience
Nils Rettberg (born 1983) was trained as brewer and maltster at Radeberger Gruppe KG in Frankfurt/Main. From 2005 to 2011 he studied Biotechnology with focus on brewing science at TU Berlin. Initiated by his diploma thesis on "Flavour active epoxydecenals from lipid oxidation" he developed a deep interest in those molecules that make beer taste either terribly good or horribly stale, but most importantly their analysis by gas chromatography/mass spectrometry. From 2011 to 2014 Rettberg wrote his doctoral thesis on "Comprehensive analysis of hop secondary metabolites" under supervision of Prof. Leif-A. Garbe. Simultaneously, he worked as research associate at TU Berlin (Chair of Bioanalytics) and VLB (Research Institute for Special Analyses), where he was involved in several research projects and teaching. In January 2015 Nils became head of the research institute for special analysis at VLB Berlin.
As a BrewingScience reviewer he focuses on beer flavour, hop chemistry, analysis of beer and raw materials, quality assurance, chromatography and mass spectrometry.
Hop Harvest Guide 2014
Gone are the days when hops were judged solely for their technical properties. Today, aromas and flavors take priority. The new Hop Harvest Guide compares individual crop years of hops. The first edition was presented at the BrauBeviale 2014. Highly skilled experts have tasted and described 21 hop varieties from the recent 2014 harvest: 14 hop varieties from Germany, France, Slovenia and the Czech Republic, four American and three Australian hop varieties. The goal is to find out as soon as possible whether there are peculiarities or differences in the 2014 harvest when compared to previous evaluations.
