Vinegar that has undergone an aging process serves as an indispensable culinary ingredient, employed across a spectrum of preparations—from delicate dressings for raw vegetable salads and leafy greens to robust marinades for red meats, as well as in fruit-based jellies featuring red-hued berries. Its primary inclusion in diverse dishes stems from its capacity to prolong freshness (owing to the pH-lowering effect of acetic acid), to intensify flavor profiles, to introduce balanced acidity, or to impart nuanced aromatic complexity. Yet, surprisingly few recognize that this naturally fermented product also harbors a range of beneficial properties capable of supporting human health. What precise health-promoting attributes does this time-honored kitchen staple possess?
Guilty acid
Natural vinegar is produced by the fermentation of white or red grapes, which affects the subsequent colour of the vinegar obtained. The fermentation is carried out by bacteria of the family Acetobacteriaceae. We can distinguish two stages of fermentation that occur in the production of vinegar: the first is an alcoholic one, which involves the transformation of the sugar contained in the fruit (possibly added) into alcohol (wine) under oxygen-free conditions, and the second, in which the resultant alcohol should be converted into vinegar, or more simply, vinegar.
The properties of vinegar
Wine vinegar should not be compared to spirit vinegar, since the latter is fertile and does not contain nutrients valuable to our health. It should also be added that only natural vinegar obtained from the fermentation process (alcoholic and vinegar) of grapes or wine (vinegar only) contains nutrients. It is said that the best vinegar from red wine is produced in France in Orléans. What are the characteristics of vinegar?
Use of vinegar
Vinegar is an excellent addition to sauces, raw ingredients made from fresh vegetables and salads with the addition of spicy, moulded cheeses and/or red meats e.g. wild, beef or poultry ducks. It is a good base for marinating the above types of meat or preparing sauces for baking. It's also a good choice as an ingredient in red fruit jellies (grapefruit, red porridge) or as an addition to a sweet-picking sauce called chutney made from red onion.
The ointment is the recipe
There are two ways to make wine vinegar at home, the shorter one by choosing red or white wine as a base, or the longer one by starting with grapes. Firstly, I recommend using a shorter method to avoid mistakes that can affect the quality of the vinegar during alcoholic fermentation. The shorter version, I'll show you below.
