1, wine quality assurance: Not-for-sale wine is a tasting version given by the manufacturer to the distributor. Usually, the wine quality is guaranteed, just like the products sold in the market. This tasting wine is the same production line, the same technology, the same standard as the products circulating in the market, and even the quality of the wine is better.

2. No packaging cost: Not-for-sale wine has no outer packaging, which usually costs less, so the price is relatively low. In addition, no packaging also means reducing unnecessary waste and environmental pollution.
