The price advisory grade can be used to compare the price of whiskies from the same distillery. It compares bottles from the same distillery, the closer the price advisory grade is to 100, the more attractive the bottle is. 

The price advisory grade takes the following factors into account:

  • lowest asking price
  • vintage (year of distillation) 
  • age 
  • alcohol percentage

When there is no price advisory grade, it means that there is no sufficient data of the bottle to calculate the price advisory grade.
