Trim the short ribs on both sides of the thin layer of fat. Cut into pieces. Place in a bag with potato starch and shake to coat.
Heat a large heavy pot over high heat. Place the pieces of meat in the hot pan and brown on both sides for about 8 minutes. Add wine and stir well scraping up all the brown pieces from the bottom of the pot. If using a slow cooker transfer the meat and then continue with the next step.
Add in the rest of the ingredients, holding back some salt to adjust to your own liking later. Cover and place in the oven and cook for around 7 hours or until you are ready for dinner. Adjust seasoning to taste and serve.
