Viticulture and winemaking at the Mervič cellar began in 1890, when Ivan Mervič, informally called JNK, bought the first piece of land to plant vines.
The old folks say he singlehandedly cultivated the earth for his vineyard and strengthened the terraces with stones and walls and planted approximately 200 vines.
Around 1910 his son Peter took over the viniculture and winemaking business and slightly increased the surface area of the vineyards. Despite the hard conditions that followed the Second World War he managed to renew some of the vineyards by digging about 1.20 m deep with the help of his son Oskar. They planted mostly the vitovska grganja, rebula, kraljevina and malvasia vines. In the seventies the production was shortly stopped and then continued in 1977.
The rich tradition and love for the vineyards passed on to the sons Andrej and Boleslav. The latter afterwards continued with viticulture and winemaking to the present day. In the last few years he increased the surface to today's 3.5 ha.
In memory of its originator the cellar bears the name JNK.
