Bloomy rind
Soft-ripened cheeses with a white mold rind, ripening from outside in. Brie, Camembert, and the entire American bloomy-rind awakening.
Technical description
Cheeses inoculated with Penicillium candidum (sometimes also Geotrichum candidum) develop a velvety white mold rind. The mold consumes lactic acid, raising surface pH, which allows proteolysis to soften the paste from the outside in. Aging is typically 3-6 weeks; finished cheeses range from chalky-cored when young to fully liquefied when ripe. Curd is barely cut and not pressed, preserving moisture for the slow surface-driven transformation.
Aging parameters
Microbial environment
Penicillium candidum (white mold rind), often co-inoculated with Geotrichum candidum (yeasty companion mold). Sometimes Brevibacterium linens contributes faint orange tints. The dominant lactic starter is mesophilic.
History
Brie has Carolingian-era documentation; Camembert was reportedly created by Marie Harel in 1791 in Normandy. The category transformed when Penicillium candidum was isolated and made consistent in the early 20th century — historically the white mold was wild and unpredictable. American bloomy-rind production began seriously in the 1980s-90s with Cowgirl Creamery, Vermont Creamery, and Cypress Grove leading the awakening; the 1989 US ban on raw-milk soft cheeses aged under 60 days continues to shape what can be imported vs produced domestically.
