The LIELKALNI farm planted two hectares of uncommon berries four years ago – golden currants, viburnum, large-fruit hazel trees, sea buckthorn, the black elder, five-flavour berries, the Chinese gooseberry, edible honey-suckle, etc. The farm has been biologically certified since 2008. In 2009 it received certification from the Latvian Food and Veterinary Service for the production of health-boosting syrups, jellies, jams and teas. Tourists can taste the teas, seasonal berries, syrups, jellies and other treats, all of which are also available for sale.
