Description
For the longest, pasteurization has been an important step of beer production solely for the large commercial breweries.
However, with the popularity of such products as Seltzer, and the advent of more styles including late fermentable additions, pasteurization needs to be on the Craft brewers' minds. So, what is pasteurization? What does it achieve? What are the limitations?
Although the lecture primarily focuses on the design and operation of tunnel pasteurizers, alternative options are considered in order to achieve microbiological stability.
Learning Objectives
- Determine the appropriate stabilization method
- Discuss tunnel, cabinet, and bath pasteurizers
- Define the term “cold spot”
- Explain why pasteurization treatments differ between various products
- Calculate pasteurization units for beer
- Describe the various features of a tunnel pasteurizer
- Discuss the internal pressures in beer containers
- Discuss the need for water treatment systems
