South of Pisarovina is Jamnička Kiselica – a place where rich sources of mineral water are found, popular among people as Jamnica.
As early as 1770, mineral springs were discovered in Jamnička Kiselica, and the first analysis of acidic water was made in 1772 by order of Empress Maria Theresa. After the analysis of the water in 1824, the campaign for the arranging of the Jamnica plant began, and in 1828, filled mineral water bottles were marketed in this part of Europe for the first time.
Local experts recommend that you try the Jamnica mineral water mixed with wine or fruit juices. Jamnica is today the most common mineral water on the market in Croatia. Today’s Jamnica facility does not offer the possibility of individual tours, but tours can be arranged for groups. Near the facility, for many years now, in mid-July, traditionally a fun and musical manifestation “Kupske večeri” has been held.
