Place quartered apples in a large stockpot and add enough water so it covers the apples by 2 inches when apples are submerged by pushing them down. (The apples will float.)
Stir in the brown sugar, cinnamon sticks, and allspice. Bring to a boil and allow to mixture to boil uncovered for an hour.
After the boiling, cover the pot, reduce heat, and simmer for 2 hours.
After simmering, let the mixture cool a bit before straining it into a bowl through a cheesecloth, gently pressing down on the solids. Discard solids and drain the liquid one more time through the cheesecloth. (You can also use a fine-mesh sieve to drain.)
