Wiki: White Mould Defects, Blooming

This Wiki article addresses blooming phase defects special to “White Mould” type cheeses such as Brie & Camembert which are generally made by adding Penicillium candidum. In addition to all the normal Coagulation, Surface, Aroma, Body, and Flavour defects, white mold cheeses also have their own special set of problems. This article is divided into the following sections:
