Roughly 18,200 grains of premium barley are used in creating just one ½ litre bottle of Koskenkorva. This barley comes mainly from the fields of Ostrobothnia. To guarantee high quality, reliable products, customised barley varieties have been developed in cooperation with the plant research organisations. These varieties are used for producing Koskenkorva and have even been given traditional Finnish names such as Kunnari, Saana and Erkki. The most important single factor in determining quality is the starch content of the barley: the higher the content, the more vodka will be distilled.

The cold winters with sub-zero temperatures and the short growing season with long days full of light offer favourable conditions for growth while ensuring the purity of the ripe barley stock. The barley is well-preserved as delivery does not require long transportation.

The Vodka is distilled more than 250 times up to 96% strength by a high quality distillation process. This is the reason why one of the world’s purest ethanol does not require separate carbon filtering. The only ingredient added to the distilled spirit is pure spring water. After this, the Koskenkorva Vodka is bottled.
