Add onions, carrots, sugar, spices and enough sauerkraut to cover everything. Add about 1 cup of white wine and bring to a boil.

Turn heat to medium low and cover pot with lid. Let simmer at least 45-60 minutes up to 2 hours. Check occasionally to make sure there is enough liquid and add some water if needed.

In the last 5 minutes, mix in Dijon mustard. Add more sugar to taste. Divide into dishes and serve with additional mustard.
