Some people have concerns about alcohol, and the conventional wisdom is that when you cook wine or any other spirit, the alcohol is evaporated by the heat of cooking. It’s true that alcohol boils at a lower temperature than water, so you’d think that the alcohol would completely evaporate before the water, but this doesn’t happen. Some of the alcohol and water combine to form an inseparable mixture called an azeotrope. So even after lengthy boiling, some alcohol remains bound with water. Not surprisingly, the cooking method and cooking time also influence how much alcohol evaporates. Flambéing removes about 25 percent of the original alcohol. Simmering on the stovetop for thirty minutes evaporates about 65 percent. And two and a half hours of simmering removes about 95 percent. So if you have religious or other personal concerns about consuming or serving alcohol, then cooking with wine is clearly not an option for you.
