In a large mixing bowl, stir together flour, baking powder, sugar, baking soda, and salt to evenly disperse everything.
Add your butter chunks, and use your fingers to rub the butter into the flour mixture until you have a coarse mixture resembling wet sand.Stir in shredded cheese and dried sage.
Add your buttermilk to this mixture and stir with a wooden spoon or rubber spatula to form your dough. This could take a bit of work. Be patient. It will come together.
Divide your dough into six and scoop it onto baking sheet. Brush each biscuit with a bit of melted butter.
Bake your biscuits for 12-15 minutes or until golden brown. Cool for a few minutes then serve warm.
