If you're having a gang over, or just want to ensure leftovers for another meal, try this beer-soaked beef roast recipe on the rotisserie.
Combine all ingredients (except beef) in large sealable freezer bag. Pierce roast all over with a fork. Add roast to bag and refrigerate for 12 to 24 hours. Discard marinade.
To cook on a rotisserie, place drip pan with ½ inch (1 cm) water under grill. Using medium-high heat, preheat barbecue to 400°F (200°C). Insert spit rod lengthwise through centre of roast; secure with holding forks. Insert meat thermometer into middle of roast avoiding spit rod.
Cook at constant heat, in closed barbecue, to desired doneness: 145°F (63°C) for medium-rare; 155°F (68°C) for medium. For an estimated cooking time chart, refer to the barbecue roasting cooking lesson.
Remove roast to cutting board; cover with foil and let stand for 10 to 15 minutes. Carve into thin slices to serve.
