Season both sides of roast with salt and pepper. Cut 4 small slits in roast and insert garlic cloves.
Add bacon grease to the bottom of a heavy stock pot or French oven and place over medium heat. When grease is hot, add roast and sear about 4 to 5 minutes and turn over and brown on the other side. When both sides of roast are well browned, pour in beer and top with fresh herbs.
Cover and lower heat to simmer. Cook covered 3 to 4 hours or until roast is tender.
