Yes Dukang wine is now available in three places, two in Henan and one in Shaanxi. The wine mentioned by Cao Cao is produced in Yichuan, Henan Province, and Yichuan County belongs to Luoyang, in the southeast of Luoyang City. The other is produced in Ruyang County and also under the jurisdiction of Luoyang City.

The registered trademark of Dukang liquor is in Yichuan, but it is also produced in two other places. Recently, all the wineries in Yichuan and Ruyang were controlled by Sanquan Food Company, and the newly established Luoyang Du Kang Holding Co., Ltd. is still producing Dukang wine.

You can basically buy it in supermarkets, but if you look at the manufacturers, you will find the above three places.
