Helping identify wild yeast contamination in beer

Bactest has developed a special culture vessel populated with a media product that will enable breweries to identify the presence of wild yeasts in beer days faster than current methods.

The media product - called YMC - comes pre-packaged in sterile gamma irradiated culture vessels that just require a beer sample to be added and placed into Speedy Breedy.  

Trials indicate Speedy Breedy can detect the presence of wild yeasts in as little as 5.8 hours compared with sending samples to a lab which takes 3-5 days excluding transportation times.

The presence of wild yeast can indicate an uncontrolled processes or insanitary procedures that can produce a number of significant problems in beer including lower terminal gravities, incorrect alcohol content, and off flavours.  

Identifying wild yeast contamination quickly means that contaminated beer is not bottled and contaminated equipment is quickly identified so that remedial action can be taken sooner avoiding spoilage of subsequent batches.

Bactest CEO Prof.Annie Brooking said: “Using our new YMC media product together with Speedy Breedy enables Breweries to identify wild yeast contamination faster than traditional microbiology methods or sending samples out to a lab for analysis. Breweries that have internal labs can benefit from fast detection times delivered with Speedy Breedy.”
