On-site PCR testing for spoilage organisms that can impact wine quality

vinoPAL combines proven diagnostic principles with innovative, proprietary PCR technology to enable accurate, rapid, and early detection of Pediococcus and Lactobacillus species at the winery.

High levels of some Lactobacillus strains can rapidly produce acetic acid or diacetyl, especially during sluggish fermentation.

These volatile compounds can have unintended negative impact on wine aroma, flavor and texture. Some species of Pediococcus are capable of producing byproducts that cause undesired texture defects, or generating biogenic amines. Methods for avoiding wine spoilage are not clear-cut, so early detection of unwanted organisms provides winemakers the opportunity to control the problem and mitigate damaging effects.

Results in Under 3 Hours - with Less Than 10 Minutes Hands-on Time


Collect a homogenous sample and centrifuge. Resuspend sample using provided proprietary Buffer A.


Transfer 5 ul of resuspended sample into provided PCR reagent tube. Place tube into Thermocycler and run program.


Remove PCR Tube from Thermocycler and add proprietary Buffer B. Dispense PCR Tube contents onto test cassette window. Wait 3 minutes and retract test cassette switch to reveal test results. One line indicates negative result, two lines indicates semi-quantitative positive results.


Simple and Cost Efficient Deployment at the Winery

The system is comprised of a small,
customized thermocycler, pre-aliquoted
 PCR reagent tubes, and proprietary buffers. Semi-quantitative results are obtained in 
less than 4 hours via hand-held disposable 
cassettes, and quantitative results can be
 tracked, stored, and exported via the Veriflow Reader.

vinoBRETT is ideally suited for proactive Pediococcus and Lactobacillus management at the winery– with a modest capital investment and affordable per-test cost. Sample collection and prep is simple, and can be completed by winery staff with minimal training.
