It is very rare to find a cider vinegar fermented by apple’s own bacteria in a shop. Even with organic apples, it is first pasteurised and then yeast is added to start fermentation.
At Highbank Orchard, they don’t use any sprays including organic ones. Therefore, their vinegar is fermented by apple’s own yeast.
It is said that organic unfiltered and unpasteurised apple cider vinegar contains a multitude of bacteria species, and some of these are able to exert probiotic effects in the gastrointestinal tract.
For this reason it is recommended to add cold water when you drink the vinegar. Hot water will kill good bacteria.
Even so, I drink it with honey and hot water when it is really cold…
