Put the apples into an glass baking dish. Drizzle the brown sugar onto each apple, dividing the sugar evenly among them. Pour the water into the bottom of the dish and bake until tender – about 45 minutes.
Pour the ale into a large slow cooker or large pot. Mix in the cloves, allspice, cinnamon, ginger and nutmeg. Set the slow cooker to medium heat or, if using a pot, set the stove to medium to low heat.
Bring the mixture to at least 130 degrees F, but do not boil. Once brought to temperature, you may strain the wassail through a sieve to remove the excess spices and make it easier to drink.
