Alcohol congener analysis
Alcohol congener analysis of blood and urine is used to provide an indication of the type of
Ingredient markers
Recently, a novel accompanying-alcohol analytic was developed that targets alcoholic-beverage-specific compounds sourced from the ingredients used during the production of the beverage.[4] These markers should ideally be unique to that beverage and not found in other beverages, food, or in the environment. Beer ingestion can be confirmed from blood samples, by targeting iso-alpha-acids-type compounds that are derived from the hops used during the brewing process.[5] Levels of these compounds have been found in blood several hours after ingestion in controlled drinking studies using "high-" and "low-hopped" beers. This methodology presents new possibilities for accompanying-alcohol analysis as ingredient-specific markers are developed for other alcohol beverages, e.g. wine and spirits.
