Wine: Good quality wine is key. It is highly recommended that you use red wine. If you are worried about the alcohol in the wine, don’t worry. It will cook off.  
The key to making the best slow cooked meatballs in a deep red wine pasta sauce, is to use good quality ingredients; this also include the wine. Use wine that you enjoy drinking. 
Browning the meat: Browning your meatballs first will help them stay intact. Be sure to bind the meat so it does not fall apart.
