How much brandy do you put in eggnog?

There is no traditional amount of brandy to put in eggnog, as the amount can vary depending on personal taste. Typically, brandy is added to enhance the flavor of the eggnog, so the amount you use should depend on how strong you want the brandy flavor to be. A good starting point is to use 1 ounce of brandy for every 1 quart of eggnog, and then adjust the amount according to your taste. If you prefer a stronger brandy flavor, you can add more brandy, or if you prefer a milder flavor, you can reduce the amount of brandy.
