Balsamic Vinegar Sweet Mother Culture - 1 Gallon

Our balsamic mother culture is produced specifically for small-scale, home production of traditional balsamic vinegar.

One gallon of mother will be enough to produce a 2-3 gallon starting batch of balsamic, which will likely evaporate down to about 1-2 gallons of finished vinegar after years of aging.

Important: this culture is only the bacterial culture required to convert ethanol into acetic acid.  It will not convert grape juice into ethanol and therefore cannot be added directly to un-fermented grape juice.

Balsamic Vinegar is a highly dense, sweet and strong vinegar.  In order to ensure that the mother does not dilute the density and sweetness of the vinegar, our mother culture is produced at or above 20° Brix final density, and above 5% acidity (as acetic acid).   We test the live mother for both Brix and Titratable Acidity and report those values on the packaging.  These numbers are essential for the calculations needed in the production process, and for ensuring a great final product.
