Yeast Growth Medium
How is Escarpment Labs yeast grown?
Our brewing yeast and bacteria cultures are grown in a base of liquid malt extract, with added nutrients specific to the microbe we are growing. This medium is always being monitored for consistency, with improvements to nutrient composition made from time to time in response to our ongoing research into the best nutrient conditions for beer cultures.
Why is Escarpment yeast slurry darker than some other liquid yeasts?
Our yeast media formulation includes molasses, which creates a darker growth medium. We include it because it provides nutrients that help to enhance the shelf life and viability of the yeast. At normal pitch rates, we have not found the colour of the yeast growth medium to impact beer colour.
