Learn about new automated methods in malt analysis, with Aaron McLeod of Hartwick College, Center for Craft Food and Beverage, USA. Discrete analyzer technology offers faster, reproducible results with less sample and reagent use. We will explain experiences compared to the standard methods and will show repeatability and method comparison results.
Beer Testing Information
Beer should ONLY be beer
Beer is the most widely consumed alcoholic beverage in the world. Beer is typically brewed from three basic ingredients: water, a starch source brewer’s yeast, and a flavoring agent such as hops. Many varieties of beer result from differences in these ingredients, the additives used, and the brewing process. Thermo Scientific instruments help in testing the quality, consistency and purity of the final product.
Isohumulones form approximately 80% of the typical bitterness of beer. Their antimicrobial effect leads to a sterile beverage, their tensioactive character stabilizes the foam, and they have a major influence on the general flavor, smell, and smoothness of beer.
The haze observed in beer is something the chemistry world refers to as “turbidity”. Depending on the type of beer, it can be a desired or undesired effect. Haze can result from proteins, polyphenols, and even carbohydrates in colloidal form.
Radeberger Group uses only the highest quality ingredients, such as, hops and malt, allowing them to maintain their standards and produce the best beers. In fact, they have received numerous awards that provide evidence of the excellence and consistency of their brands.
In 1887 Murphy and Son Limited was established by Albert John Murphy as a supplier of brewing components. While developing his products, Murphy realized the importance of formulating water treatment techniques that could be used to complement the specific characteristics of a beer.
Ion chromatography is an efficient technique for the analysis and quantification of ions in solution. Although there are several techniques that have been used for the analysis of beer, ion chromatography is rapidly becoming the method of choice.
The specific aroma of beer is predominantly controlled by ingredients derived from hop, in particular the exact pattern of isohumulones. The BeerNHop solution is based on HPLC and provides an easy tool to accurately determine the isohumulone profile in the final product and in raw material for a systematic approach of innovative flavors and qualities that can make the difference.
