What proportion wine to vinegar make red vinegar?

Here's why:

* Red wine vinegar is made through a fermentation process. It starts with red wine, which is then fermented by bacteria. This process converts the alcohol in the wine into acetic acid, which gives vinegar its characteristic sour taste.

* Mixing wine and vinegar won't create the same result. You'll just have a diluted mixture of wine and vinegar, not a true red wine vinegar.

To make red wine vinegar, you need to follow a specific process:

1. Start with good quality red wine.

2. Allow the wine to age in a cool, dark place. This allows the natural bacteria to start the fermentation process.

3. The wine will gradually turn into vinegar. This can take several months to a year.

4. You can speed up the process by adding a "mother" of vinegar. This is a film of bacteria that helps accelerate the fermentation.

It's important to note that making vinegar at home can be tricky. You need to ensure sanitary conditions and understand the fermentation process.

It's often easier and safer to purchase high-quality red wine vinegar from a reliable source.
