How is grape spirits made?

Grape spirits are generally naturally fermented, and the fermentation process needs to last for 2-4 months. This process generally needs to be fermented twice at different temperatures to retain more grape fruit flavor. Using high-sugar grapes, glucose can be quickly converted into alcohol, and other impurities such as fusel oil are also reduced in this process. Grape spirits generally do not need blending, just need to adjust the alcohol content. Grape spirits generally do not need to be aged in oak barrels, or in oak barrels for a short period of time (2-3 months), and are generally aged in steel tanks, pottery tanks, etc. Grape spirits keep the aroma of grape fruit to the greatest extent, and its biggest flavor is "original flavor". Therefore, grape spirits have high requirements for grape raw materials, and the brewing of grape spirits is more demanding than brandy.
