façade of the former Ovaltine factory, Kings Langley. The building was redeveloped into housing in 2002. Ovaltine was very popular in Britain, and was manufactured at Kings Langley in Hertfordshire using a process that included GEA Wiegand
falling film evaporators to concentrate liquid malt extract, which was then dried under vacuum in steam-heated band dryers. The
art deco-style Ovaltine factory in Kings Langley is a well-known local landmark. Production ceased in 2002 and the factory has now been redeveloped as luxury flats. Near the factory was a health farm run by the Ovaltine works, set up as a model farm and a health resort for disadvantaged children, which operated until the 1960s. Later, the farm land was sold and is now largely occupied by the
M25 motorway. The Ovaltine Egg Farm is now the site of
Renewable Energy Systems Ltd. Due to its high-caloric and sugar content, Ovaltine has been a popular drink for climbers since the early days of mountaineering, including being carried during the first successful summitting of
Mount Everest in 1953. In October 2002, the food and drinks division of Novartis, the maker of Ovaltine, was bought by Associated British Foods. ABF currently produces Ovaltine in Switzerland, China, Thailand, Nigeria and Australia. In Canada, Ovaltine is produced by Grace Foods in biscuit and powdered drink forms. In the United States Nestlé manufactures Ovaltine. In
Hong Kong, Ovaltine, like
Horlicks, is known as a café drink. It is served at
cha chaan tengs as well as fast-food shops such as
Café de Coral and
Maxim's Express. It is served hot, or on ice as a cold drink. In Brazil, it is commonly mixed with vanilla ice cream. In the Asian market, it is a chocolate ice cream flavoured with Ovaltine powder. The
McCafé in Hong Kong provides "Ovaltine Crunchy Latte" and other drinks and desserts. In
Malaysia and the
Philippines, Ovaltine has lost its popularity to
Milo. Ovaltine is sold in
Tetra Pak cartons for cold serving and is widely available in shops and supermarkets, yet it has a lower profile than similar beverages in the market. In Japan, Ovaltine was sold for a short period in the late 1970s by
Calpis Industries (presently Calpis Co., Ltd.), but it was not a commercial success. In Australia,
Ovalteenies are sold as round tablets of compressed Ovaltine, eaten as
candy. Brazilian fast-food chain
Bob's offered since 1959,
milkshakes and
sundaes made with Ovaltine where it goes by the name of "Ovomaltine," which became a flagship product of the fast-food chain in Brazil. In 2016, McDonald's acquired exclusive rights to sell "Ovomaltine"-branded milkshakes. Brazil has the second-largest Ovaltine factory, in
São Paulo, and is the second-largest consumer market for the product after
Thailand. The Brazilian Ovaltine differs from other varieties, originating from an assembly-line malfunction that made the powder
crispier that is still maintained today. In 2011, Ovaltine was banned in Denmark under legislation forbidding the sale of food products with added vitamins unless claims about their effectiveness are proven. ==In popular culture==
