PIKA FastOrange® Wild Yeast Enrichment Bottles are sterile, single use bottles prefilled with 40 mL of FastOrange® Wild Yeast Bouillon (Broth). Just add a sample directly into the bottle, mix, and incubate at ambient temperature (25 °C/ 78 °F). For specific detection of S. cerevisiae var. diastaticus, keep at 35° C / 95 °F. Monitor medium for build-up of haze or sediment, which may appear together with a color change towards yellow.
FastOrange® Wild Yeast medium is specifically formulated to detect all wild yeasts – those yeasts other than the typical brewing yeast strains – anywhere in the production line or surrounding environment.
The principle of the differentiation is described in EBC method 126.96.36.199 Saccharomyces Wild Yeasts, Cu-differentiation.
