Bratwursts, Sauerkraut, and Potatoes

6 to 8 large bratwursts, boiled
2 bags (16 ounces each) sauerkraut, rinsed and well drained
1 medium yellow onion, sliced
1/2 teaspoon caraway seed (highly optional)
1 tablespoon ground black pepper
6 to 8 medium red potatoes, peeled and quartered
32 ounces beer (I like using Guinness or Rogue Dead Guy Ale)

Put everything in the crock pot. Turn it on low. Walk away for at least eight hours.
