Cut the beef into bite sized cubes, if necessary.
Add to a bowl, sprinkle with salt.
Pour beer over the beef, cover and refrigerate for 1 hour and up to 12.
Preheat a grill to medium high.
Remove from beer, pat dry.
Thread through heat safe skewers, brush liberally on all sides with hoisin sauce.
Grill until grill marks appear on all sides and beef is cooked to medium rare, re-brushing with hoisin sauce each time you turn the skewers.
Serve warm.
