Description
By this point in the process we have a product that has been either completely fermented out, or left with some residual, fermentable sugars. The next step is often referred to as the “black box”. Maturation is necessary for not only sedimentation but also for desired flavor changes. The types of tank being used, the temperature, and the yeast concentration are only a few of the aging parameters that can impact the final beer flavor as well as its physical appearance. This lecture acknowledges this complexity before explaining the one-tank and two-tank operation approach.
Learning Objectives
- Explain the key components that impact the aging of beer in a conventional process
- Define the key metrics that help describe the progress achieved during beer aging
- Explain how better sedimentation can be achieved
- Describe haze composition, and how its formation can be prevented
- Explain the mechanisms behind physical stability
