Beer Stability: A perspective on beer flavour stability

23 June 2014 | By Patricia Aron, Senior Hops Chemist, MillerCoors

The educated beer consumer’s heightened expectations have changed the game in terms of beer quality. Today’s beer drinkers are more sophisticated, fickle and less forgiving when it comes to beer flavour. Consequently, flavour instability is now one of the most critical quality problems faced by the brewing industry. Achieving beer…

The many styles of wine fermentation

1 May 2014 | By Linda F. Bisson, Professor & Geneticist, Department of Viticulture and Enology, University of California, Davis

Wine production is inherently a microbial process wherein components of the grape are transformed into flavour and aroma characteristics of the wine. If wine is a symphony of sensorial experiences then the grape precursors are the instruments and the microbes are the members of the orchestra. Wine fermentations may be…

It has variously been estimated that there are between 1,000 and 2,000 different chemical species in beer, probably twice as many as are present in wine. It is an extraordinarily complex liquid. Not all of those chemical components make a substantial contribution to the quality of beer, but many do.…

4 January 2012 | By Susanna Buratti and Gabriella Giovanelli, Department of Food Science and Technology, University of Milan

The rapid pace of change in the wine industry calls for fast methods providing real time information in order to assure the quality of the final product. NIR and MIR spectroscopy combined with sensory-instrumental methods (electronic nose and electronic tongue) can provide an ideal solution to monitor molecular and sensory…
