Although there is no viticulture, but a curious wine production. On the rocky island Olkiluoto near the southwest coast at the level of 61 degrees latitude several nuclear power plants are operated. In 2001, 150 red vines were grown near the site Zilga set; the extreme hardy Vine comes from Latvia, The warm water of the cooling system of individual reactors flows through plastic pipes under a nearby field, such as lawn heating in a football stadium, and keeps the ground frost-free throughout the year. Initially, it was assumed that up to 3,000 kilograms of grapes per year, in fact, the first yield in 2003 at just under 100 kilograms was significantly lower. The project is running as part of a state-funded research program that makes good use of waste heat from nuclear power plants. Watermelons, corn and lettuce have already been grown on the heated area. Traditionally, Finland produces berry-like drinks from different berries.
