Wine and Choucroute, a real classic.
Choucroute, more properly called choucroute garnie is a famous Alsatian recipe for preparing sauerkraut with sausages or other charcuterie, and often potatoes. Every restaurant and cook has their own recipes, with their own pork cuts, spices, and exact preparation method such as heating the sauerkraut in a dry white wine, preferably Riesling.
This is one case where I do not suggest any additional wine pairings. Go for a dry Alsatian Riesling or Gewurztraminer.
