What does e and j mean in brandy?

The letters "e" and "j" in brandy don't refer to specific qualities or designations. There is no established system within the brandy industry that uses these letters to denote anything.

Perhaps you're thinking of something else?

Here are some common designations and terms used for brandy:

* VS (Very Special): At least 2 years old

* VSOP (Very Superior Old Pale): At least 4 years old

* XO (Extra Old): At least 6 years old

* Napoleon: Often used to indicate an age between 6 and 10 years

* Extra: Can indicate an age above 10 years

* Region of Origin: Brandy is often named after the region where it's produced, such as Cognac, Armagnac, or Jerez

* Grape Variety: Some brandies are named after the specific grape used, like Ugni Blanc or Tempranillo
