Preheat oven to 425F.

In a processor add flour, baking powder, baking soda, salt, and sugar.

Pulse to combine. Add the bacon fat (cold) or the cold butter, and sour cream, process until well combined.

Add the beer, process until just combined.

Add to a well-floured flat surface, pat into a rectangle. Using a cold rolling pin gently roll into a large rectangle, about 1 inch in thickness, using as few strokes as possible.

Sprinkle with chopped bacon.

Fold the dough into thirds as you would a letter about to go into an envelope. Roll lightly, once in each direction to about 1 inch thickness, sprinkle with bacon, fold in thirds again. Gently roll into about 1 1/2 inch thickness (this will give you flakey layers).

Using a biscuit cutter, cut out 6 biscuits. Place in a baking pan that has been sprayed with cooking spray.

Brush biscuits with melted butter, sprinkle chopped bacon.

Bake at 425F for 10 to 12 minutes or until the tops are golden brown.
