About the beer spoilage detection dipslides

Beer Spoilage / Brewery Dipslides

Our Beer / Brewery Displides feature MRS Agar (culture medium). This agar measures / grows lactic acid bacteria. This means that if your sample contains lactic acid bacteria, colonies will grow on the dipslide agar. You can then compare with the included chart to assess the level of infection.

Each box contains 10 dipslides with each dipslide housed within a shatterproof plastic tube.

Lactic Acid Bacteria Testing

Intentional microbe growth goes hand in hand with brewing beer with brewer's yeast as an example of microbes that work in partnership with the industry.

However, not all microbes are welcome with some micro-organisms contaminating and spoiling the product. Contamination can come from various sources such as raw materials, malted barley and unclean equipment / bottles.

Spoilage Organisms

Although some bacteria cannot thrive due to the brewing process, Lactic acid bacteria can grow in these conditions. Lactic acid bacteria is essential to some types of brew (such as sour beers). However, if levels of lactobacilli are too high, an 'infection' can occur which then spoils the beer. Because lactic acid bacteria can be found almost anywhere, chances of overgrowth are likely. Any excessive contamination of the beer can cause changes in flavour (sour or buttery taste), odour and appearance.

MRS agar supports the growth of lactobacilli including Lactobacillus brevis (very common beer spoiling bacteria). These dipslides test for the lactic acid bacteria group as a whole and are not selective for specific strains. This dipslide also includes actidione (a fungal inhibitor). This should prevent yeasts and moulds from growing on the dipslide.

If you suspect a lactobacilli / lactobacillus infection, MRS agar dipslides can help you to confirm this. Alternatively, you may want to test your beer on a regular basis to be alerted to any potential problems before they arise.

Unlike basic formulations of MRS agar, cycloheximide has been added to these dipslides to inhibit the growth of yeast and other micro flora. This makes it easier for the user to view the lactic acid bacteria growth and assess the level of contamination.

How to use the Brewery dipslides

1.Collect samples of your beer.

2.Twist the cap on top of the dipslide and remove it from its container / tube.

3.Make sure you do not touch the agar with your hands.

4.Immerse the dipslide within the beer sample for 10 seconds.

5.Once finished, remove the dipslide from the sample. Allow excess fluid to drain off.

6.Replace the dipslide within its container / tube.

7.Incubate the dipslide.

8.Compare results with the chart provided

Dipslides should be incubated for approx 48- 72 hours for best results.

Please note that the minimum order for these slides is 150 boxes and due to them being made to order, delivery may take up to 5 weeks. These dipslides will have a shelf life of 8 months+.
