The Khan Krum Winery is located in the village of the same name in Preslav. It was established in 1939, but today it produces significantly less wine than before. It specializes in processing white grapes, but it can bottle both white and red wines. The climatic conditions in the area are more favourable for growing white varieties. Traminer Khan Krum is one of the wines of the recent past that impressed with its quality. Today, award-winning high-quality Muscat, Sauvignon Blanc and Chardonnay wines are produced here.
