Place chocolate pieces into a heat proof bowl.
Heat the wine in a saucepan and bring to a boil. Then reduce heat and let simmer for 5-10 minutes until reduced to approximately 1/4 cup.
While the wine is simmering, heat the heavy cream in another saucepan until it begins to boil.
Pour the hot heavy cream over the chocolate pieces and let sit for about 30 seconds to 1 minute. Then stir with a fork until the chocolate is completely melted.
Pour the red wine over the chocolate mixture and stir until incorporated.
Refrigerate until firm, at least two hours.
Scoop the chocolate mixture and roll into 1-2 inch balls. Use parchment paper to keep it from sticking.
Roll the truffles in chopped almonds or dip in melted chocolate for topping.
