A CLOSER LOOK
How to recognize it
Yeast and lactic-acid-bacterial cultures used together to ferment a bread-based kvass liquid. Exact strains and culture carriers are not disclosed here.
In the kitchen
Initiate fermentation of the prepared bread liquid, contributing acidity, aroma and possible alcohol.
Not sweet-rice starter or proof that a finished drink contains live cultures. Liquid and dried culture preparations exist; supplier composition must be checked.
