Which cereal is used to make vinegar and whiskey?

This is a bit of a trick question! Neither vinegar nor whiskey are made from cereal.

Here's why:

* Vinegar is made by fermenting any sugary liquid, like fruit juice, wine, or even sugar water. The most common type of vinegar is made from fermented apple cider.

* Whiskey is made from fermented grains, but not just any cereal. The most common grains used are barley (for Scotch and Irish whiskey), corn (for American bourbon), rye (for rye whiskey), and wheat (for wheat whiskey).

So, while cereal grains can be used to make alcohol, they are not the primary ingredients in vinegar or whiskey.
