Pika FastOrange Yeast is a nutrient medium developed for the craft brewing and winemaking markets. It will enrich and display the presence of both yeasts and mold, while suppressing bacteria growth. This is a powerful tool allowing brewers to maintain and confirm cleanliness in the brewhouse, as well as confirm finished product quality. Growth of yeast is indicated by turbidity and precipitation in the medium, and acid producing species are further identified by a color change in the medium.
FastOrange Yeast Agar is a culture medium developed specifically for the detection of microbial contaminations during the brewing process and in brewery products. Beer spoilers such as lactic acid bacteria and pediococci are easily detected by a color change in the culture. The strength of this color change is relative to the acid production of the bacteria, and can be a useful tool for isolating high acid producing strains for further propagation.
