Today, I bottled the vinegars that I started last year. The guanabana vinegar is extraordinary. I know it has untested, unverified medicinal properties. We have so many trees here, the fruit is dropping heavily now. This is a wonderful way to preserve fruit.
Vinegar contains bioactive compounds. According to a review published in Food Chemistry, vinegar has high concentrations of polyphenols, organic acids, and micronutrients.
