Hey all!
This is my first post in the message board and basically just wanted to know what you people are doing nowadays in your breweries/breweries you work for regarding micro contamination identification.
I am working at newly started production site in Denmark and I am responsible for setting up the quality control practices. I´ve read a bit on the solutions and methods available and it seems to me that plate counts and agar plate screening is still a quite spread practice in the industry. Of course there is PCR in its different variants, but for the time being we are looking into other alternatives...
Having said that, I have also come across new solutions where prefilled sterile test tubes are sold with selective media where one only needs to fill up with a certain volume of beer/wort or yeast slurry. If there is a considerable change in color / turbidity, then that can be interpreted as a positive. Yes, you do not get a quantitative result but at this stage we could easily do with a reliable qualitative test.
What do you guys do out there, plate, PCR, liquid media, both? Highly interested in hearing input.
Cheers,
Manuel
