I'll let you in on a secret. I'm not wild about liver.
Liver can be baked, broiled, or fried (often smothered in onions) or eaten raw (liver sashimi). It is often made into spreads such as liver pâté, foie gras, and chopped liver or sausages such as liverwurst.
In addition to the wines mentioned in our food pairing table you might consider a Zinfandel.
