Fermentation is a chemical change, as new substances, alcohol and carbon dioxide are produced. It would be extremely unlikely that leaving a glass of Grape Juice to ferment would produce a drinkable wine. Further oxidation to vinegar would be almost inevitable.
it is a chemical change, because you can no longer get the grapes back.
Fermentation is a chemical change. Sugars are chemically changed, and converted to carbon dioxide, ethanol, etc.
Fermentation is a chemical process.

Chemical
NADH (or FADH2) donates its electrons to a molecule producedby the same metabolic pathway that produced the electrons carried by NADH (or FADH2).
carbon dioxide
Grapes themselves are neither, but the juice in grapes, especially of the more sour variants are acidic.
Grapes contain many different chemicals, including racemic acid which gives grapes their tartness.

Fermentation is a chemical change. Sugars are chemically changed, and converted to carbon dioxide, ethanol, etc.
It is a chemical change because it can not be reversed

NADH (or FADH2) donates its electrons to a molecule producedby the same metabolic pathway that produced the electrons carried by NADH (or FADH2).
lacto fermented
Conundrum red wine is made by fermenting the wine on the crushed grapes, pressing juice from the grapes, fermenting in vats and finally bottling some time after fermentation has stopped.
Grapes is a chemical change because refrigerator.
D. Dry ice subliming is a physical change. Chemically, it's still CO2.
Carbon Dioxide
It is a chemical change. Fermentation causes bonds to break within a compound and new bonds form thus chemically changing the initial 'reactant'.
Fruit, when fermented, can be turned into alcohol. Grapes, for instance, make wine. You can create alcoholic cider by fermenting apples, etc.
Must. the correct answer is STUM which is the more common name . The only word I have ever seen or heard is 'Must'.
