1. Different production processes: the production processes of white wine and red wine are different. White wine is fermented from clarified grape juice, while red wine is fermented from grape juice and grape skin residue (including peel, seeds and fruit stalks). Because red wine needs more raw materials and more complicated fermentation process, the production cost is relatively high, resulting in relatively expensive price.

2. Different aging methods: Liquor and red wine have different aging methods. Generally speaking, white wine does not need to be aged in oak barrels, while red wine usually needs to be aged in oak barrels. Aging in oak barrels can give red wine more complex taste and aroma, but it also increases the cost and time. The aging process of red wine is complicated, which leads to price difference.
