Open the wine and taste it to be sure it’s good.
Combine everything except the berries in a large saucepan over medium-high heat and stir to combine.
Boil until sugar dissolves, stirring occasionally.
Reduce heat and simmer for about 15 minutes.
Strain out cloves, allspice – remember, there are 6 of each, and grab out those 2 cinnamon sticks as well. Trash that stuff, you’re done with it.
Add berries and cook until berries burst, about 6 minutes. Feel free to smash them against the side of the pan with your wooden spoon if they’re not cooperating. If you like your sauce on the thicker side, cook a few additional minutes.
Remove from heat and cool. Store in the fridge. Save the hassle on Thanksgiving and make this ahead of time. It’s even better the next day.
