Hypersensitivity and reactions to foreign substances (allergens). The consumption of tyramine- and histamine-rich foods can be the cause of headaches (migraines). Caution is advised with genuine sulphite allergy sufferers. For them, even minimal amounts of sulphur can trigger "sulphite asthma". They should avoid wine and other alcoholic drinks containing sulphur. The symptoms can be similar to asthma and include itching, hives, runny nose and a drop in blood pressure. Around 10% of asthmatics are "sulphite allergy sufferers".
Wine can also contain allergenic substances. These are mainly protein compounds (if these substances are used in wine), histamine, sorbitol and tyramine (especially in red wines with BSA), sulphur (contained in almost every wine) and also the alcohol (ethanol) itself. However, there are different limits in the mg/l range for each substance. A list of all substances with limit values can be found under ADI (Acceptable Daily Intake).
The Wine lexicon helps me to keep up to date and refresh my knowledge. Thank you for this Lexicon that will never end in terms of topicality! That's what makes it so exciting to come back often.
