How does heat affect vinegar?

Heat can accelerate the evaporation of volatile compounds in vinegar, which may alter its flavor and aroma. Additionally, heating vinegar can cause a reduction in acidity, as the acetic acid can break down at high temperatures. However, moderate heating can also enhance its ability to dissolve substances, making it more effective in culinary applications like marinades. It's important to avoid excessive heat to preserve the vinegar's key properties.
