No. The trademark of Diaoyutai Zhenmi Wine belongs to the sales company, not the production winery. Therefore, Diaoyutai Zhenmi Wine is an OEM wine and not a developed wine. To distinguish between developed wine and private label wine, you only need to identify the ownership of the trademark. If the trademark belongs to the winery, it is called "developed wine", and if the trademark belongs to the seller, it is called "OEM wine."
