One pack of Nottingham yeast is good for up to 5 gallons. The Nottingham strain was selected for its highly flocculant (precipitating) and relatively full attenuation (transforming sugar into alcohol) properties. It produces low concentrations of fruity and estery aromas and has been described as neutral for an ale yeast, allowing the full natural flavor of malt to develop. Good tolerance to low fermentation temperatures, 14C (57F), allow this strain to brew lager-style beer. Recommended 14 to 21C (57 to 70F) fermentation temperature range.
