Sữa Ông Thọ was mass-produced in the Saigon–Biên Hòa area and widely consumed in the Republic of Vietnam, produced by Friesland Foods (now FrieslandCampina) prior 1975.
It was used in coffee, mixed with hot water to produce hot milk for babies and young children to drink (since fresh milk had to be imported and was thus expensive), and used for dipping French bread (bánh mì) and in other dessert applications.
After the 1975 Fall of Saigon, the factories manufacturing Sữa Ông Thọ, along with all other commercial and private properties, were collectivized by the communists, and the facilities came under the state company Vinamilk, who continued to produce Sữa Ông Thọ condensed milk under the same name used domestically and elsewhere in Indochina.
[2][3] Friesland Foods continued production of Sữa Ông Thọ - Longevity Brand after 1975 in the U.S. and Canada for the North American market, especially catering to Overseas Vietnamese consumers, and increasingly to Western consumers as the popularity of Vietnamese coffee and cuisine in general, increases.
[4][5] Sun Hing Foods, Inc., in Northern California, is the sole distributor for Longevity Brand in Canada and the United States.
