These plates are used for the detection of all yeasts and bacteria found in your brew.

• Allows the brewer to detect a broad collection of wild yeast strains
• Plated agar
• Send in the sample to Brew Plate Laboratories for microbe identification

Each quadrant is made up of different media that detects various species.

Quadrant 1: Wallerstein Nutrient Media (WLN) is non-selective and detects all wild yeast, pitching yeast and some bacterial strains that are common in brew.

Quadrant 2: Lee's Multi-Differential Agar (LMDA) detects lactic acid producing bacteria including Lactobacillus and Acetobacter species. Acid producers are easily detected by a change in the media color from green to yellow.

Quadrant 3: Hsu's Lactobacillus/Pedioccocus Agar (HLP) detects Lactobacillus and Pediococcus bacteria. For optimal growth, an anaerobic gas generator sachet should be used during incubation.

Quadrant 4: Lin's Cupric Sulfate Media (LCSM) detects non-Saccharomyces wild yeast and inhibits the growth of brewer's yeast.
