Steep the crushed grain in 2 gallons (7.6 L) of water at 155 ºF (68 ºC) for 30 minutes. Remove grains from the wort and rinse with 2 quarts (1.8 L) of hot water. Add the liquid and dried malt extracts and bring to a boil. Add the hops and Irish moss as per the schedule. Add the Sumatran coffee and two chocolate varieties at the end of the boil. Add the wort to 2 gallons (7.6 L) of cold water in a sanitized fermenter and top off with cold water up to 5 gallons (19 L). Cool the wort to 75 ºF (24 ºC). Pitch the yeast and aerate the wort heavily. Allow the beer to cool to 68 ºF (20 ºC). Hold at that temperature until fermentation is complete. Transfer to a carboy, avoiding any splashing. Add the Kona coffee and condition for one week, then bottle or keg. Carbonate and age for two weeks.
