Histamine Tracker
Sheep cheese (aged)
Aged sheep's milk cheese accumulates histamine through the same aging process as cow's milk cheese, with levels rising the longer it matures.
Sheep's milk cheese follows the same fundamental pattern as other aged cheeses — bacteria break down proteins during aging and release histamine as a byproduct.
-
Aging is the driver — whether it's sheep, cow, or goat milk, the key variable is time spent aging. Older, firmer sheep's milk cheeses like aged Manchego or Pecorino tend to carry more histamine than younger ones
-
Fresh sheep's cheese — young, soft sheep's milk cheeses have had little time for histamine to develop and are generally better tolerated than their aged counterparts
Looking for fresh or lightly aged sheep's cheese is a reasonable approach if you enjoy this style.
