This is way easy to make. To make 5 gallons, should be able to multiply most everything x5 to get what ya need with a couple exceptions. One, use the same amount of yeast from what I've read, do not up the amount. Two, don't up the whole cloves much, they are way powerful. I'm not sure about the cinnamon sticks, but I like cinnamon myself, so would probably up it as well. Good luck with this.
Oh the nutmeg and allspice, if you add those, remember that a little goes a long way with those spices.
