Our Koskenkorva distillery is located in the village of Koskenkorva in Southern Ostrobothnia, Finland. Grain spirit produced from pure Finnish barley is the key raw material for our alcoholic beverages.
The Koskenkorva distillery is a modern production plant that has a highly developed producing technique, processes and a wide product range, which allow for an exceptional material efficiency. The Koskenkorva plant operates according to the principles of a circular economy, with all outputs utilised either internally or by customers. We are able to utilise the barley grain in full.
In addition to grain spirit, the Koskenkorva plant produces starch and raw material for animal feed. Even the carbon dioxide generated in the process is collected and used for example in greenhouse cultivation.
We also have our own bioenergy power plant at Koskenkorva. The bioenergy power plant uses barley husk as a fuel and produces steam energy for the distillery. The use of renewable fuel has helped the Koskenkorva plant to cut down its fossil carbon dioxide emissions by approximately 50%. The plant’s self-sufficiency in terms of fuel in steam generation is about 60%. The circular economy at the Koskenkorva distillery brought Altia the Green Company of the Year award in 2018.
The Koskenkorva plant uses about 210 million kilos of Finnish barley a year, which represents about 15% of the total barley harvest in Finland. One way of putting this figure of around 210 million kilos into perspective is by imagining 17 trucks full of barley, delivered to the plant every weekday of the year.
In continuous distillation, barley mash is ceaselessly fed into the distillation process. In Koskenkorva distillery, the distillation happens in five distillation columns, each of which have their own roles and functions. There are also four supporting columns that recycle fusel alcohols from the main distillation and raise distillation efficiency up to 99%.
There are also several advantages in continuous distillation when compared to regular batch distillation, such as the ability to distill larger amounts more efficiently. Also, there is no need for unnecessary washing. This decreases water consumption, chemical and energy use, and ensures uniform quality.
