chemical change
Production of gas: If there is a sudden release of gas, bubbling, or fizzing, it may indicate a chemical change. Formation of a precipitate: A solid substance forming in a solution can indicate a chemical change has occurred. Color change: A visible change in color of the substance can be a sign of a chemical reaction. Change in temperature: A noticeable temperature change, either an increase or decrease, can be an indicator of a chemical change taking place.
Baking soda (called "sal aeratus" in the 1800s) and buttermilk (or milk soured with vinegar or lemon juice) react together to produce carbon dioxide, like baking powder and water, or yeast. This makes the dough rise.

When wine is completely soured, it forms wine vinegar, which can be mixed with oil to make salad dressing, or used to pickle cucumbers, etc. If the wine is only partially soured, I have found that if you mix it with grape juice, or with grape flavored drink of some kind, the result can be quite drinkable (and even delicious).
