Sterility Testing:
Only microbiology culture can detect a few organisms per mL, as required
for bottle sterility testing. Culture requires up to 15 days and
microbiology experience.

‘Matching’ sensory evaluation: Z-Brett detects Brett at much lower concentrations than sensory evaluation, before 4EG & 4EP can be smelled/tasted. Mixed cultures of wine spoilage bacteria can produce barn-yard odors and off-flavors. 4EG & 4EP defects persist after removal of Brettanomyces by filtration.
Confirmation: Z-Brett is for screening; a confirmatory test is recommended prior to initiating expensive remediation, or to definitively distinguish Brettanomyces from other spoilage yeasts.
