Brandy is distilled spirits made from the fermentation of fruit juices. The most common fruits used are apples, grapes, and pears. There is a little difference between cognac and brandy though people see them as the same. Brandy is any spirit that is made from the fermentation of fruit juice while cognac is spirits that are made from the fermentation of grape juice. The fact that cognacs are made from grape juice makes them fit the definition of brandy. In simple terms, all cognacs are brandy but not all brandies are cognac. Cognacs are those brandies that are made from the fermentation of grape juice in a particular region in France called Cognac but the other brandies can be produced anywhere in the world. There are very strict rules as to how cognacs should be prepared and slight negation of these rules renders cognac to be regarded as normal brandy.
