Combine the ingredients in a mortar and grind to a coarse powder and then pack in a percolator, or other suitable maceration vessel. Pass the alcohol through the percolator over a period of 48 hours to create the Seamans Bitters essence. If macerating, allow the mixture to macerate for 2 days with occasional agitation, then filter and reserve the liquid.
To make the bitters, take 1 ounce of the bitter essence and add it to 4 pints of 40% alcohol.
To make the Seamens Bitter Liqueur from the above essence, take 1 oz of essence and combine it with 1700 ml of 25% alcohol, 300 ml of 60% simple syrup.
