It is best to start making black bean wine one or two months before 1 delivery. The specific method is: take 500 grams of black beans and 7 cans of rice wine, fully dry the black beans, put them in a clean pot and fry them until they crack, then soak them in a closed container with rice wine, take out a proper amount when drinking after delivery, and steam them in water.
Because wine can promote blood circulation, black bean wine can't be drunk continuously in large quantities, so as not to cause uterine bleeding.
