The term pitch rate refers to the amount of yeast that is added to cooled wort. Pitch rate is generally referred to in cells per milliliter. Pitch rates make a dramatic difference in the final flavor and aroma profile of any beer. Ester production is directly related to yeast growth as are most other flavor and aroma compounds.
A low pitch rate can lead to:
- Excess levels of diacetyl
- Increase in higher/fusel alcohol formation
- Increase in ester formation
- Increase in volatile sulfur compounds
- High terminal gravities
- Stuck fermentations
- Increased risk of infection
High pitch rates can lead to:
- Very low ester production
- Very fast fermentations
- Thin or lacking body/mouthfeel
- Autolysis (Yeasty flavors due to lysing of cells)
