Method of inventorying liquor

A liquor inventorying method for determining the amount of liquor dispensed from a plurality of liquor bottles, wherein at least some of the liquor bottles contain different types of liquors having different costs, the method comprising the steps of:

• a. separating the liquor bottles into a plurality of categories based on cost of the liquor in the bottles so that each category includes bottles having similar liquor costs;
• b. determining the approximate average cost of liquor per weight in each category;
• c. weighing the bottles in each category before dispensing liquor from the bottles to determine an original weight of liquor in each category;
• d. re-weighing the bottles in each category after dispensing liquor from the bottles to determine a new weight of liquor in each category;
• e. determining an amount of liquor dispensed from each category by subtracting the new weight from the original weight;
• f. determining an approximate cost of liquor dispensed from each category by multiplying the amount of liquor dispensed from each category times the approximate average cost of liquor per weight in each category;
• g. determining an amount of revenue received for each of the categories;
• and
• h. comparing the amount of revenue received for each category to the approximate cost of liquor dispensed from each category to determine an approximate amount of liquor that was not properly dispensed from each category.
