Two families. There are two distilleries for Beijing Erguotou 56% Liquor, namely Beijing Fangzhuang Erguotou Liquor Longfeng Co., Ltd. and Beijing Longxing Haofangzhuang Liquor Co., Ltd., so there are two. Erguotou, as the name suggests, is the "Guotou" wine made when the raw materials are fired in the second pot. This wine is the purest, has no peculiar smell, is high in concentration but not strong, and is really mellow and fragrant.
