Selective plating contaminant test (wild yeast and bacteria) for 10 samples + service call (quantitative and comprehensive)



We can do selective plating contaminant testing from liquid sources (e.g. beer, wort, fermentor, yeast starter/slurry, bright tank, bottles, kegs, water), a swab (e.g. tanks, hoses, heat exchangers, other equipment), or airborne contaminants (“check plates”).  Selective plating from liquid sources are performed using either membrane filtration or the pour plate method.  Liquid sources, swabs, and airborne contaminants are plated/captured on the following types of selective media: Universal Beer Agar, WLD, WLN, LCSM, NBB, LWYM, and SDA to allow a comprehensive selection of wild yeast, anaerobic bacteria, and aerobic bacteria (some of these media grow normal yeast also that we use as a basis of comparison).  If you choose the “Selective media contaminant test for 10 samples of your choice + service call” option above, we will come to your brewery or workplace with supplies to collect samples aseptically (following the process in this video).
