Metabolism (biochemical metabolic process) refers to the uptake, transport and chemical conversion of substances in an organism, as well as the release of metabolic products into the environment. The resulting intermediate products are called metabolites, the entirety of the metabolic pathways is called metabolism. Fermentation and the processes involved in bottle ageing are also such metabolic processes. From this, metabolomics is an analytical method that can be used to determine these metabolic processes. Recently, it has also been used in the analytical testing of wines. This is because every wine is individually composed on a molecular level and has its own "chemical fingerprint". Scientists at the Max Planck Institute for Molecular Plant Physiology in Potsdam (Brandenburg) have discovered this.
In the past, you needed a wealth of encyclopaedias and specialist literature to keep up to date in your vinophile professional life. Today, Wine lexicon from wein.plus is one of my best helpers and can rightly be called the "bible of wine knowledge".
