Vinegar (balsamic)

Balsamic vinegar goes through a uniquely long fermentation and aging process, which gives it its distinctive sweetness and places it among the more concerning vinegars for histamine sensitivity.

• Extended aging — traditional balsamic is aged for years, sometimes decades, in wooden barrels; longer aging is generally associated with higher histamine accumulation, though the specific relationship is not precisely documented

• More concentrated than other vinegars — balsamic is thicker and more reduced than most vinegars, and many people with histamine intolerance report stronger reactions to it compared to lighter options

Among vinegars, distilled white vinegar or fresh lemon juice are generally considered lower-histamine alternatives.
