You may want to dial back the spice additions. i just kegged my Winter Warmer. I did a robust porter with a similar grain bill as your recipe and with .5 tsp of All Spice, Cinnamon, Nutmeg, Cloves at 1 min, and the aroma and flavor is overpowering right now. i just hope that it calms down between now and the Holidays.
