25 oz Light rum, Banks
              18 oz Sencha Green Tea
              12 1⁄2 oz Dry vermouth, Noilly Prat
              
              1⁄2 oz Bitters, Bittermens Boston Bittahs
          Notes
    
          Combine all ingredients and chill in a refrigerator.
Serve in a bowl with a large block of ice.
Garnish each serving with grated nutmeg.
Curated slightly: Bank's is a brand of Light rum, and changed the number of servings to a much more realistic amount.
