Lonkero
In Finland, lonkero, also called long drink, refers to a ready mixed drink made from gin and, most commonly, grapefruit soda, although other long drink flavours include cranberry and lime. In Finland, lonkero is available in stores and restaurants, where it can be on draught, bottle or can. In 1952, Finland was preparing to receive increased numbers of visitors connected to the 1952 Summer Olympics. As a compromise following the Finnish prohibition , the country was living with a strict state-controlled alcohol policy. In order to help vendors facing a wave of foreign customers, the state allowed some liberalization; Alkoholiliike, the national alcoholic beverage retailing monopoly, introduced two brands of pre-mixed, bottled, ready to drink long drinks. These were the Gin Long Drink (gin with grapefruit) and the Brandy Long Drink (brandy with Pommac), then co-manufactured with Hartwall. The latter product was discontinued in the 1970s, after which the term long drink became primarily associated with the gin-and-grapefruit beverage in Finland. Until Finland joined the European Union in 1995, the production of long drink was strictly controlled by the government. After joining the EU the government was no longer allowed to control the production, and this led to the birth of several long drink brands by different companies. Some experimented with using lemon, orange or other flavors instead of grapefruit. Others started manufacturing mild long drinks based on fermentation rather than on adding spirits. The same composition can be achieved by diluting a 10% cider into 5% with water and gin and grapefruit flavors, and the 5.5% product can be sold in grocery stores. The 2000s saw the reintroduction of the brandy long drink, now manufactured by Laitilan Wirvoitusjuomatehdas.
