That is the "Mother" beginning to form. Many people cherish the
mother to use in making their own vinegar by adding wine.
From Wiki: "Mother of vinegar can also form in store-bought vinegar if
there is some non-fermented sugar and/or alcohol contained in the
vinegar. This is more common in unpasteurized vinegar. While not
appetizing in appearance, mother of vinegar is completely harmless and
the surrounding vinegar does not have to be discarded because of it.
It can be filtered out using a coffee filter, used to start a bottle
of vinegar, or simply ignored."
A neighbor keeps a Mother in a jug. It gets all the leftover wine.
