Yesterday afternoon, Wang* called and asked Liu** and I to have dinner together. We had hot pot. Also eating with us was a nephew of Wang*, who runs a winery. He brought a bottle of wine made from dried sweet potatoes. The alcohol content was quite high, and there was a smell of moldy dried sweet potatoes. Other than that, the taste was good, and it was quite soft on the palate. Liu** and I both felt good. We made an appointment with the factory director to leave some for us if there is more wine produced. The wine yield is very low. 500 kilograms of dried sweet potatoes were invested, and only 30 kilograms of wine were produced. The wine was good, but I actually blacked out in the end.
