Do you want to test beer, wine or juices for beverage spoilers? For fast and specific screening and detection of microbiological spoilage parameters in beverages, a wide product line of qPCR kits is offered.

Spoilage bacteria and yeasts can cause turbidity, change of taste and off-flavors in beverages. To avoid losses or recalls, it is important to test for spoilage organisms in all areas of production. For fast and specific screening and detection of microbiological spoilage parameters in food and beverage production, we offer a wide product line of test kits.

Relevant parameters in beverage production

The following spoilage bacteria and yeasts are of special interest in the beverage industry and should be monitored:

Alicyclobacillus

Alicyclobacillus is a gram-positive, strictly aerobic, acidophilic and thermophilic spoilage bacteria, especially important for the fruit juice industry, where it has been shown to produce high amounts of guaiacol imparting off-flavors to fruit juices. Alicyclobacillus is of special interest to the fruit juice canning industry because common pasteurization techniques do not deactivate the spores. Therefore early screening of Alicyclobacillus is very important for the industry since contamination can lead to considerable loss of quality and subsequently to economic losses for the producers. Alicyclobacillus acidoterrestris is considered the most important spoilage species within the Alicyclobacillus genera, but other e.g. Alicyclobacillus acidocaldarius have als been isolated from spoiled products.

Brettanomyces (Dekkera)

Dekkera bruxellensis (anamorph Brettanomyces bruxellensis) is a spoilage yeast in beverages, especially important for the wine industry, where it has been shown to produce high amounts of volatile phenols (4-ethylphenol and 4-ethylguaiacol) imparting off-flavors to red wines. The yeasts of the species Dekkera bruxellensis are responsible for serious economic losses in the wine industry owing to their ability to spoil wines by the production of ethylphenols. Some authorities consider “brett” to be responsible for 90% of the spoilage problems in premium red wines. However, in the production of beer (especially craft beer or Belgian beer specialities), Dekkera bruxellensis is often not considered as contaminant, but as flavor enrichment.

Lactobacillus

Lactobacillus may be part of a regular fermentation process, but can also cause undesired acidification of beer or spoilage of fruit juices. Lactobacilli are killed by standard pasteurization.

Megasphaera

Megasphaera are gram-negative, strictly anaerobic bacteria. They are well-known as beer spoilers producing off-flavors and turbidity.

Oenococcus oeni

In wine production, the malolactic fermentation is supported by Lactobacillus. During this process, the bacterium Oenococcus oeni can be added as highly specialized bacteria. It effects a transformation of malic acid into milder lactic acid. However, depending on the desired type of wine, the presence of Oenococcus oeni may also be undesirable.

Pectinatus

Apart from Megaspaera, Pectinatus is another important spoilage bacterium in beer production. The gram-negative and strictly anaerobic bacterium causes turbidity and off-flavors reminiscent of rotten eggs.

Pediococcus

Pediococcus is a genus of gram-positive lactic acid bacteria which are considered as contaminant in wine and beer. However, in some beer styles, the presence of Pediococcus may be desired.

Pichia

Pichia is a genus of yeasts in the family Saccharomycetaceae. It is used in the fermentation process in winemaking, but it can spoil wine when present in high quantities. Pichia may also cause turbidity and off-flavors in beer.

Saccharomyces

Saccharomyces is a genus of fungi including various species of yeasts. One of the best known species is Saccharomyces cerevisiae which is used in the production of beer, wine or bread. The species Saccharomyces diastaticus is a spoilage yeast in the wine and beer industry.

Beer analysis

Beer analysis can help you to avoid product recalls, to minimize production losses and to prevent damage to brand image. We offer test systems for in-process control and/or for on-line final product control. Use different analytical modules to establish your customized monitoring of microbiological beer spoilage organisms in beer and beer products: Either extremely fast or maximal sensitive detection and specific identification is possible by combining different methods of sample preparation and detection with real-time PCR.

What is the right test kit for you?

Our “decision tree” helps you to find the real-time PCR kit that best suits your needs in beer analysis.

Our portfolio includes QuickGen screening kits, GEN-IAL® screening kits and beer-specific kits. The new QuickGEN line is characterized by a simple and rapid sampling and assay process, providing results within two hours after sampling. The test is based on filtration or centrifugation with subsequent qPCR and allows an extreme rapid and specific screening and detection in beer without pre-enrichment (reduced sensitivity, no differentiation in vitality). Analysis is very easy to perform even for untrained users.

The established qPCR kits based on pre-enrichment of the sample allow a sensitive screening and specific detection. The new concept of pre-coated 8-well qPCR strips (TPBD, TPYB) enables the user to screen and identify safely over 30 beer spoilage bacteria and yeasts in one qPCR run without misinterpretation and can be performed on common multiplex blockcyclers.

Wine analysis

We offer several test kits for wine analysis, e.g. for detection of the yeast Brettanomyces (Dekkera bruxellensis) which may spoil the taste and flavour of the wine.
