Preheat your oven to 350F.
In a two-quart saucepan over medium heat, combine the butter, sugar, vanilla, and dark corn syrup. Stir gently until everything is melted and well combined, then let it cool for about 10 minutes.
Whisk your eggs until frothy.
Add the whisked eggs to the cooled corn syrup mixture, then mix in the semisweet chocolate chips and pecans along with the barley tea.
Pour the filling into a prepared 10-inch pie crust.
Bake at 350F for about one hour to one hour and fifteen minutes until the center is set.
Allow the pie to cool completely before slicing.
