Siebel-Instituts agar medium for the selective detection and quantitative determination of Saccharomyces wild yeast populations in samples from the brewing process.

• Certified by the Siebel-Institute for technology
• Ready-to-use powder with batch-adjusted cristal violet colution
• Functionality tested with strains originally isolated from the brewing environment

The specially developed nutrient composition, the media primarily enhance the growth of Saccharomyces wild yeasts, whereas the normal brewing culture is mainly inhibited by the addition of cristal violet solution. LWYM can be applied to filterable samples (e.g. beer and rinsing water samples) but also in brewing culture yeast with high cell counts.
