What is a spirit distilled from the fermented juice of grapes called?

Here's why:

* Brandy is a generic term for any spirit distilled from fermented fruit juice.

* Grape brandy is the specific type of brandy made from grapes.

* Cognac is a type of grape brandy that is produced in the Cognac region of France.

* Armagnac is another type of grape brandy, also produced in France but in the Armagnac region.

So, while all cognac and armagnac are brandy, not all brandy is cognac or armagnac!
