Histamine Tracker
Port wine
Port combines alcohol's DAO-blocking effect with high histamine from fermentation and fortification — a particularly heavy combination.
Port is a fortified wine — which means it carries histamine from fermentation, plus extra alcohol that makes it harder for your body to clear that histamine.
-
Fortified and complex — Histamine in wine is primarily produced during fermentation, especially through bacterial activity, and port's additional alcohol further impairs DAO compared to regular wine
-
Red grape base — Like red wine, port is made from red grapes with their skins, and red wines are consistently among the most commonly reported triggers for people with histamine intolerance
If you enjoy fortified wines occasionally, white or tawny styles may be slightly easier than ruby or vintage ports.
