Apple vinegar is very healthful. Doctors advise to drink it every day as preventive measures. I offer you to prepare apple vinegar by your own. I have an idea how to do it on your own. There is an apple vinegar recipe.

Ingredients: apples, sugar, water.

Instructions: Wash ripe apples very carefully. Dice them and put them into an enamel saucepan with a wide bottom. Cover apples with hot water (60 - 70° Celsius degrees). Add sugar on the basis of 0.2 pounds sugar for 2.20 pounds sweet apples (or 0.4 pounds sugar for 2.20 pounds sour apples). Put the saucepan with apples at a warm place (but not in the sun). Mix the saucepan contents often. In two weeks filter everything and pour into large bottles to ferment for two weeks. Then pour vinegar into other bottles. Don't shake up them.
