Macerate 2.5 kilograms of dried wormwood, 5 kilograms of anise and 5 kilograms of fennel in 95 liters of 85 percent ethanol by volume. Let the mixture steep for at least 12 hours in the pot of a double boiler. Add 45 liters of water and apply heat; collect 95 liters of distillate. To 40 liters of the distillate, add 1 kilogram of Roman wormwood, 1 kilogram of hyssop and 500 grams of lemon balm, all of which have been dried and finely divided. Extract at a moderate temperature, then siphon off the liquor, filter, and reunite it with the remaining 55 liters of distillate. Dilute with water to produce approximately 100 liters of absinthe with a final alcohol concentration of 74 percent by volume (4).
