Buy a juicer, put a whole-ass bag of apples through that fucker, plus a knob of ginger. Simmer that shit in a pot with a few cinnamon sticks and whole cloves.
You can thank me later.
Also if you do actually do this and its your first experience juicing: clean your juicer immediately! Im serious, clean that shit while the cider is simmering. If you let it sit out 'til the next day you WILL regret it.
Apple cider is seasonal because it relies on apple harvesting, but there is no reason to not have pumpkin spice any time of year except for artificial scarcity. The same with eggnog except people don't like eggnog much to begin with.
Fun fact. American folk legend Johnny Appleseed was actually a very successful businessman. Rather than planting apple trees randomly, he founded tree nurseries for cider production. He wore pauper's clothes because he wanted to, not because he was some vagabond.
Remember, friends don't let friends ruin unpasteurized cider by sticking it on a stove and spicing the hell out of it. Only do that with pasteurized cider; it was already ruined when you bought it.
