Description

Brewers are well aware, or should be well aware, of the importance of providing sufficient nutrients to the brewing yeast to carry out fermentation. However brewers are NOT in the business of making yeast; they are in the business of making beer, obviously! Excess yeast growth represents an actual brewing loss. Therefore the brewers are left with the difficult task of fine-tuning the amount and quality of nutrients. But what are those important nutrients? This lecture covers the various brewing yeast growth requirements and how some, like glucose concentration, can affect the overall yeast metabolism.


Learning Objectives

  • Describe the nutritional requirements of yeast
  • List the necessary nutrients obtained from wort
  • Explain why oxygen is vital
  • Explain the uptake and utilisation of nutrients
  • Understand the impact of glucose repression
