The present invention provides, compared to known methods, a significant improved method of inducing malolactic fermentation in wine or fruit juice without the concomitant degradation of citric acid, production of acetic acid, and production of diacetyl herein within a short period of time by inoculation wine or a fruit juice directly with a concentrated culture composition of malolactically active and non-citric acid fermenting bacteria at an economically feasible concentration and accordingly, to avoid the tediously, risky and costly processes of re-hydration, activation, and adaptation which are currently required with commercial malolactically non-citric acid fermenting starter cultures.
Also provided is a method of inducing fermentation in a liquid composition comprising a fermentable compound comprising the use of a dry activation composition, wherein in the range of 80 to 200 g of said dry activation composition comprises
i) A nitrogen source
ii) In the range of 60 to 140 g sugar
iii) In the range of 5 x 10 11 and 5 x 10 13 colony forming units of a microbial organism capable of fermenting a fermentable compound, wherein addition of 1 L water to said dry activation compositions results in an activation solution comprising
i) A nitrogen source
ii) In the range of 60 to 140 g sugar per L
iii) In the range of 5 x 10 8 and 5 x 10 10 colony forming units per ml of the microbial organism capable of fermenting at least one fermentable compound |
