Headaches due to alcohol consumption are caused by various factors. Excessive drinking with too high quantities leads to intoxication and as a consequence to a hangover the next day. Too much fusel oils and acetaldehyde in wine also favour the occurrence. Other causes are too much loss of fluids and minerals. Alcohol causes the body to become severely dehydrated. Under certain circumstances, more fluid is excreted than the amount drunk. Important minerals such as magnesium are lost in the process. Even with low alcohol consumption, allergy sufferers may experience headaches or migraines due to histamine and tyramine, which are particularly present in red wine.

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".Prof. Dr. Walter Kutscher
