White wine vinegar is useful for a range of tasks, from flavouring salad dressings to household cleaning. Making your own white wine vinegar at home is also a great way to use up half-empty bottles of white wine that have been rattling around in the fridge for a while.
Buy a glass container or ceramic pot with a spigot if you don't already own one.
Buy a 240 ml container of commercial vinegar Mother (a ball of enzymes that floats in the vinegar) from a home brew or wine making shop. You can also buy this online.
Pour two cups of white wine diluted with one cup of water into the pot.
Add the vinegar mother to the pot.
Cover the pot with cheesecloth and attach it securely with a rubber band or string.
Place the pot in a warm place where it can sit undisturbed.
Add 2 1/2 cups white wine to the pot three times over the next two weeks.
Let the vinegar sit for a total of 12 weeks minimum.
Bottle the vinegar when it tastes and smells like vinegar. Pour it into clean bottles or jars with a funnel. It will last for three or four months.
Make more vinegar, if you want, by leaving the vinegar Mother in the pot and repeating this process.
Vinegar Mother is the same for white wine vinegar and red wine vinegar. It's the wine that makes the difference.
Making white wine vinegar takes longer than red wine vinegar -- up to six months.
If your white wine vinegar is cloudy, pour it through a coffee filter to clarify the liquid.
