Combine red wine, salt and rosemary in a bowl. Allow to stand at room temperature for 3 hours.

Heat a large griddle or cast iron skillet over high heat. Place the steaks on the hot pan, and cook for about 8 minutes per side, or to the desired degree of doneness. The internal temperature should be at least 145° F for medium-rare. Pour in the wine mixture and allow it to boil for a minute. Serve steaks with sauce on a deep platter.
