Info: In this session we will help you to get to know your microscope and show you top tricks and hints that will be beneficial to your brewing process

For good brewing you need a healthy yeast with a good viability, a good cell count and free from contamination.
You can perform a yeast count by using a Haemocytometer. A haemocytometer consists of a defined grid etched onto the slide surface. The number of cells per ml can be calculated.
There are two types of microbiological contamination, wild yeasts and bacteria, both these contaminants can cause hazes and off flavours.
You can monitor the presence and levels of contamination using the microscope, by identifying rod shaped bacteria (bacilli) and round shaped bacteria (cocci).
You can observe for wild yeast by looking at cell shape, size, opacity and uniformity. This often goes hand in hand with knowing your own yeast and getting to know its appearance under the microscope .
