Currant juice

Currants are among the more histamine-active berries, and their juice concentrates that effect.

• Histamine liberation — like many deeply colored berries, currants may prompt the body to release its own stored histamine, on top of whatever is already in the juice itself

• Darker vs. lighter juices — darker berry juices like black currant tend to be flagged more often by histamine-sensitive individuals than lighter options like white grape or apple, which are generally better tolerated; this is an observational pattern rather than an established mechanistic rule

Lighter fruit juices are often a more comfortable alternative for people who notice reactions to berry-based drinks.
