In a large pot, bring the cherry juice, cherries, and sugar to a boil. Reduce heat and simmer for 30 minutes. Remove from heat and let cool to room temperature. Add almond extract and everclear. Carefully pour into mason jars, leaving room to add the cherries. Divide the cherries evenly between the jars before placing the lids on them. Serve immediately or store in either the refrigerator or a cool, dark place.
