My girlfriend makes all of our keezer beer signs, so no credit to me for the artwork. I generally go about half of what recipes call for with spices because they can really overpower a beer quickly, so we use 1.5 teaspoon per 5 gallon batch with a combo of cinnamon, ginger, nutmeg, cloves, and allspice. I might throw a couple of dashes pumpkin pie spice in during the whirlpool for aroma.
