Fermentation
General Considerations The rate of fermentation depends on the pitching rate, the temperature at pitching (pitching heat) and the attemperation used during fermentation. The level of dissolved...
Oxygen in Wort prior to Pitching
General Considerations Synthesis of lipids (sterols and unsaturated fatty acids) by yeast requires oxygen. Wort lipids provide some unsaturated fatty acid, but insufficient sterol. Oxygen is...
Zinc in Wort prior to Pitching
General Considerations Zinc is an essential trace element required for yeast growth and therefore insufficient zinc will lead to slow or sticking fermentations. There is no general correlation...
Nitrogen in Wort prior to Pitching
General Considerations The nitrogenous constituents of wort include amino acids, peptides, polypeptides, proteins, nucleic acids and their degradation products. Some of these nitrogenous constituents...
