In a small saucepan, add the balsamic vinegar, maple syrup if desired, herbs if using, and fresh blackberries. Gently crush some of the blackberries with your fingers or the back of a spoon.

Bring mixture to a boil over medium heat, then immediately reduce heat to low. Allow the mixture to gently simmer, stirring occasionally.

Continue simmering until the glaze has reduced by one-third to one-half and coats the back of a spoon. Remove saucepan from heat and let cool slightly.

Pour the slightly cooled glaze through a fine mesh strainer to separate the liquid glaze from the berry and herb solids.

Transfer the strained berry mixture to a separate container as a jam. Both the glaze and jam will continue to thicken as they cool. Store both in airtight containers in the refrigerator.
