Istenič is the largest wine producer in Bizeljsko and one of the largest producers of sparkling wine in Slovenia. They are also the region's most professionally organised vineyard in terms of receiving guests, with a multi-lingual website clearly listing different wine tasting packages and menus available with prices, and even the ability to make a booking online. Accommodation is also available in the form of eight modern two-bedded rooms, most with tiny balconies looking out over the vineyards.
