Saccharomycodes ludwigii

Saccharomycodes ludwigii is a yeast species best known for being a contaminant in alcohol and fruit juice production. It is highly resistant to typical environmental stressors such as high temperature, high sugar concentration, and high sulfur dioxide concentration. It is often referred to as the "winemaker's nightmare," as it contaminates products by outcompeting desirable yeast species. However, S. ludwigii strains are currently being tested in the growing low-alcohol beer industry.
