John Kosovich Wines was established in 1922 by Johns father Jack and his brothers, who emigrated from Croatia shortly before the outbreak of World War 1.

After working cutting railway sleepers in the states South West and then in the gold mines of Kalgoorlie, and operated as Westfield Wines the current property was purchased in 1922, with the first original vines planted in that year still gracing the entrance to the winery.

The underground cellar was dug by Jack and his brothers with help form neighbours and their trusty Draft horses to do the bulk of the heavy moving. An impressive 7m long White Gum beam was cut from a tree felled by Jack in the hills east of the property and remains the main supporting structure for the cellar 'roof' and the broad ave used by Jack to shape the beam hands from it today.

John took over the winemaking at the tender age of 15 more by necessity than a conscious decision to become a winemaker, and in the early days sweet whites (sherry) sold to the Aussies and some 'rough red' that found its way to the local Croatian and European community remained the staple of the busniess.

John realised that these wines were not right for the Perth climate, and in the early 1960's made the bold move to change the vineyard to begin producing dry white wine. Riesling was one of the first new varieties plantes, with Chenin Blanc, Chardonnay and Verdelho following.

The winery operated under the name Westfield Wines up until 2003 when the decision was made to change the name to honour John Kosovich’s 50th vintage.

Estate Vineyards / AVA

Swan Valley:

The original Swan Valley vineyard was first planted in 1922 and now mainly produces Chardonnay, Verdelho, Cabernet Sauvignon, Chenin and our fortified styles. Here the vineyard enjoys a warm, even climate and soils of sand over rich loam, which produces grapes with full fruit ripeness. All the fruit is harvested by hand.


The need for expansion in the 1980’s led to the purchase of our Pemberton property in the cool South West corner of the state. With its soils of gravely loam and substantially cooler climate, we employ viticultural techniques that ensure low yields from our vines. Coupled with a slow ripening season this then produces intense fruit concentration in the grapes. There are 15 acres under vines producing Chardonnay, Verdelho, Shiraz, Cabernet Sauvignon, Merlot and Pinot Noir.


In 1995 John Kosovich was awarded the Order of Australia medal for his contribution to the wine industry.

In 2004 he won the prestigious Jack Mann Medal for services to the Western Australian wine industry and in that same year the winery was awarded the Best West Australian Small Producer at the Perth Royal Wine.
