Designation for a controlled process of all the necessary steps in alcoholic fermentation (see there in detail). An important prerequisite is appropriate must treatment. Important steps to initiate fermentation are the required or desired temperature of the grape must, the addition of the desired type of yeast (alternatively, allowing spontaneous fermentation), room temperature control, any necessary interruption of fermentation in case of desired residual sugar, and the accompanying control of the entire process. See also under fermentation faults and boiling.
The wein.plus encyclopaedia is a comprehensive, well-researched reference work. Available anytime and anywhere, it has become an indispensable part of teaching, used by students and myself alike. Highly recommended!
