Active Dry Yeast (ADY) is widely recognized as a reliable technology of choice for beverage fermentation. It offers a great amount of flexibility and options related to applications, sensorial characteristics and technical aspects.
The purpose of the presentation is to « demystify » ADY and present results of a recent study on the impact of different hydration conditions on fermentation kinetics and on sensory profile of beers.
Following hydration conditions will be considered more specifically:
Hydration in Water of various qualities (distilled, mineral, tap)
Hydration in wort of various densities
Hydration under different temperatures (8°C to 40°C)
Hydration with or without agitation
