Season the ribs generously with salt and pepper.
Heat the vegetable oil in a large heavy pot with a lid over high heat.
Brown the ribs on all sides, in batches if necessary.
Remove the ribs and pour off all but a couple tablespoons of the rendered fat.
Return the pot to the stove, lower heat to medium and saute the garlic and ginger for about 3 minutes.
Add the ribs back to the pot.
Add the beer and the vinegar.
Stir and then cover and simmer for 2.5 hours.
Preheat the oven to 300 degrees F.
Pour the hoisin sauce over the ribs, move the pot to the oven, and cook, uncovered, for 30 minutes.
Remove ribs and ginger from the sauce.
Strain fat from the top of the pat so that you're left with just the good stuff.
