Fermented food?: When you burp up stomach contents (reflux or gerd) into the mouth, it is usually acidic (stomach acid) or bitter (bile from small intestine that can occasionally backflow into the stomach). Sweet is not a common complaint. So this needs more investigation. Could be a sign of fermented material you ate still in the stomach if within 3 or 4 hours of eating ). A gastroenterologist is the one to see.
