Музей йогурта, Yogurt museum in Studen Izvor, Bulgaria

The Yogurt Museum occupies a two-story building in the center of Studen Izvor and displays exhibits about how Bulgarian yogurt is produced and fermented. The rooms show traditional production techniques and equipment that have been used for generations.

The museum opened on 29 June 2007 in Studen Izvor, the birthplace of microbiologist Stamen Grigorov, who in 1905 identified Lactobacillus bulgaricus as the agent of yogurt fermentation. The opening coincided with the first Festival of Bulgarian Yogurt in Tran, with folklore, drawing and essay contests, and a competition for the best homemade yogurt.

The museum displays household items and furnishings from 19th century Bulgarian homes, illustrating how dairy making was central to local life and tradition. These exhibits show how yogurt production shaped daily routines and eating habits in this region.

The museum occupies a two-story house in the village center, near the birthplace of Dr. Stamen Grigorov. The ground floor holds a traditional 19th-century living room and an exhibition of clothing from the Tran region; the upper floor has a library and an exhibition hall. Visitors are sometimes offered a taste of local yogurt.

This is the only museum of its kind in the world dedicated entirely to the history and science of yogurt. It documents not only the chemical discovery but also the handmade methods that families in this region passed down through generations.
