What's the difference between white type and century-old simplified type?

There is no difference between the white type and the century-old type. Niulanshan Erguotou is a very popular liquor with a retail price of 15 yuan per bottle, which is called Bai Niu Er by drinkers to distinguish it from other Niulanshan Erguotou. Bai Niu Er is liquid wine, which is what we usually call alcoholic liquor. Simply put, it is to produce edible alcohol from grain first, and then mix it with seasoning.
