I see some white spots on my olives. Are they ruined?
The white spots that you see on the olives are a naturally occurring result of the olive undergoing fermentation. It is harmless, and does not affect the taste of the olives. The probiotic bacteria of the Lactobacilli strain can be found in the brine and on the surface of the olives, and are responsible for the white “biofilm” we see sometimes in our olives. This film is formed due to the high concentration and availability of sugars, amino acids, vitamins and other nutrients during the process of fermentation, providing the ideal environment for the survival and growth of these bacteria. Our olives are lacto-fermented preserved, meaning they are preserved in brine and are not exposed in high temperature treatments or pasteurized. Once the olives are covered in the brine, that white layer will be dissolved. We do not have an actual measure for the concentration of the probiotic bacteria on our olives, but taking under consideration that we hand pick them, preserve them in spring water with organic vinegar and low salt concentration, they are not exposed in harsh conditions (temperature, sterilization) and we see the “biofilm” formation, all these are indications that the probiotic bacteria are at least active and kicking in our olives.
