1 cup red wine 
2 cups beef, chicken, or vegetable broth 
1 bay leaf 
5 to 6 black peppercorns 
  Remove roast from pan and pour off any fat. 
  
 Place over high heat (use 2 burners if necessary) and deglaze pan with wine and broth, scraping any bits stuck to the bottom of the pan with a wooden spoon or spatula. 
  
 Once these solids are dissolved, pour liquid into a saucepan and add the bay leaf and peppercorns. Reduce for 5 minutes over high heat or until reduced by 1/3. 
  
 At this point you basically have a jus which could be used to sauce your roast. To create a gravy, reduce the heat to medium and whisk in 2 tablespoons of white roux. Return to a simmer, whisking constantly. 
  
 Continuing to cook once a simmer has been reached will result in a smoother sauce, but not a thicker one. Since all starch thickened sauces thicken as they cool, it's a good idea to make your gravy a little on the loose side.
