Contamination Testing

Brewing Bacteria Analysis/Wild Yeast Microbial Analysis 

Selective media beer spoiler screening – $45 per sample
Yeast, beer or swab samples are plated on selective LMDA media with cycloheximide to suppress brewer’s yeast. Colony identification with gram stain for beer spoilers. (Example: Lactobacillus, Pediococcus, Enterics, Acetic Acid Bacteria, Wild Yeast).  Genetic PCR Testing can be added for an additional cost. Amount of sample needed for processing: 1ml-100ml (See contamination testing form).

  • Complete screening for all genres of brewing bacteria
  • Brewing bacteria identified to the genus level
  • Aerobic/Anaerobic results interpreted and reported within 5 to 7 days
  • Only ASBC approved methods used

PCR beer spoiler screening – $99 per sample per test
Rapid PCR genetic assay that is accurate, sensitive, and specific for the detection of the most Detrimental beer spoilers.  This testing helps facilitate timely product release and proactive monitoring of in-process beer.  PCR testing is best used as a tool to help compliment selective media testing.  Tests available include:

  • Brettanomyces/Dekkera
  • Lactobacillus/Pediococcus
  • Hop tolerant (HorA, HorC) lactic acid bacteria
  • STA+ yeasts including S. cerevisiae var. diastaticus
  • Sensitivity is 10 cfu/ml
  • PCR results interpreted and reported with 1 to 2 days

TO OBTAIN ACCURATE TEST RESULTS, IT IS CRUCIAL TO FOLLOW THE APPROPRIATE COLLECTION METHODS AND PACKAGING DIRECTIONS.

IMPORTANT: THE CONTAMINATION TESTING INSTRUCTION AND ORDER REQUEST FORM MUST ACCOMPANY YOUR SAMPLE OR TESTING WILL NOT BE CONDUCTED.
