Abstract
A method of introducing yeast into a fruit juice such as grape must to be fermented is disclosed. The method comprises feeding dry yeast into a flowing stream of the fruit juice and delivering the flowing stream of fruit juice with the yeast in it to a mixer (10). The fruit juice and yeast emerging from the mixer is fed into a fermentation tank. The yeast can include nutrients selected from inactivated yeasts, yeast autolysates, yeast cell hulls, yeast extracts, amino acids, peptides, proteins, sterols, ergosterol, thiamin, biotin, pantothenic acid, niacin, riboflavin, pyridoxine, minerals and inorganic nitrogen in the form of ammonium salts.

A method of introducing yeast into a fruit juice to be fermented, the method comprising:
- dispersing dry yeast nutrients in a dry viable yeast to form a dry mixture of nutrients and viable yeast;
- feeding the dry mixture of nutrients and viable yeast into an uninterrupted flowing stream of fruit juice such that the dry viable yeast comes into direct contact with the fruit juice without a previous rehydration step of the dry viable yeast;
- delivering the flowing stream of fruit juice with the dry mixture of nutrients and viable yeast in it to a mixer;
- and
- feeding the fruit juice and dry mixture of nutrients and viable yeast emerging from the mixer into a fermentation tank.
A method of producing wine, comprising:
- dispersing dry yeast nutrients in a dry viable yeast to form a dry mixture of nutrients and viable yeast;
- feeding the dry mixture of nutrients and viable yeast into an uninterrupted flowing stream of grape must such that the dry viable yeast comes into direct contact with the grape must without a previous rehydration step of the dry viable yeast;
- delivering the flowing stream of grape must with the dry mixture of nutrients and viable yeast in it to a mixer;
- and
- feeding the grape must and dry mixture of nutrients and viable yeast emerging from the mixer into a fermentation tank;
- and
- permitting fermentation to proceed in the fermentation tank.
