About the Winery


Established in 1998 Hewitson winery is situated in the heart of the Barossa Valley on the historic Seppeltsfield Road and boasts some of the oldest vines in the world. Our fruit is sourced from historic, dry-grown vineyards in the Barossa Valley and also from single site vineyards in Eden Valley, McLaren Vale and the Adelaide Hills.

At Hewitson, we believe great wines are an expression of the soils they are grown in and the season they grow. Through knowledge and experience we strive for balance, structure, concentration, power and breeding. Proudly, through solar energy, water recycling and encouraging natural biodiversity, Hewitson brings these wines to your table environmentally sustainable.

Our Family

Dean at Barrels 1


Dean completed his winemaking degree at Australia’s world-famous Roseworthy Agricultural College in 1986. He then spent a decade “getting his hands dirty” in one of Australia’s leading wineries.

It was time to “hit the road”.

Dean travelled throughout France, working vintages and visiting regions including Bordeaux, Burgundy, Champagne, Beaujolais, The Rhone and Provence. All this “old world” experience gained was not enough to quench Dean’s appetite to learn more.

Dean then travelled to California to study at the renowned UC Davis, California, completing his Masters in Winemaking and at the same time immersing himself in the wines of Santa Barbara, Napa Valley, Sonoma Valley, Monterey, Oregon and Washington State.

Now he spends his days overseeing the winery and production and developing export and domestic markets …and often found “throwing a snag” on the barbecue for the winery team.

The Vineyards

Our Vineyards

Hewitson’s vineyards are spread throughout the renowned wine regions of South Australia, including the Barossa Valley, McLaren Vale and the Adelaide Hills. The heart of our winemaking is however always within the Barossa, as we produce all of our wine from our Seppeltsfield Road facilities.

Dean Hewitson at Hewitson Baby Bush Vineyard # 1 WM


Nestled in the heart of South Australia’s famous Barossa Valley lays Hewitson’s Old Garden, an ancient vineyard of Mourvèdre planted in 1853 by Friedrich Koch. Old Garden has seen the entire history of Australia’s wine industry evolve around it. Having survived floods, fires, famines and the worldwide spread of Phylloxera in the late 1800s, this oldest-known surviving planting of Mourvèdre recently celebrated its 160th Birthday.

Eight rows of this rare and unique planting remain to this day at Rowland Flat and produce winemaker Dean Hewitson’s much-lauded single-vineyard table wine bearing the Old Garden name. He recognised the potential of these ancient dry-grown vines back in 1998, which until then had only been used to make fortified wines, blended table wine and sparkling wine.

“One of the most valuable things I learnt is that the best wines in the world come from those optimal conditions where the grapes ripen just before the season closes,” comments Dean Hewitson. “The Old Garden grows in two metres of sand over limestone leaving the bunches dry and healthy. Mourvèdre is an extremely late ripening variety and these conditions allow harvesting at the end of the season with perfect maturity.” - Dean Hewitson.

Geologists have confirmed that the Old Garden sits on what was the bottom of an ancient lake, once part of the Para River. The secret to the vines’ longevity is their extremely deep roots going down 10 metres into the ground.

“The roots of these vines are so deep that even on the hottest day, while every other vine in the Barossa Valley has shut down, The Old Garden’s leaves are bright and perky, tracking the sun as if each leaf is a radar,” he adds. “This depth of root system helps provide a wonderful evenness in the wine, year after year.” - Dean Hewitson.

Also located in the Barossa Valley lays ‘selection massale’ from the 1853 planting of Old Garden Mourvèdre. One of the first things Dean Hewitson did when starting Hewitson Wines in 1998 was take cuttings from the Mourvèdre vines, in which he created the Baby Bush vineyard. The Baby Bush vines now have a minimum age of 10 years.

As well as our pride and joy Mourvèdre plantings, Hewitson produces wine from a number of other plots in the Barossa, including the Falkenberg shiraz, Dorrien bank shiraz and Duck Ponds road Sangiovese vineyards.

Grapes with Flash


We produce our crisp LuLu Sauvignon Blanc from a superbly situated vineyard, nestled between Hahndorf and Mount Barker on one of the highest and coolest slopes in the Adelaide Hills. The Adelaide Hills has become one of Australia’s premier Sauvignon Blanc regions.


Hewitson’s Gun Metal Riesling is grown in the renowned Riesling region, Eden Valley. The eastern facing slope that this vineyard sits on provides shade from the warm afternoon sun, creating the perfect Riesling growing location.



Hewitson’s Mad Hatter shiraz is grown in the McLaren Vale, at Blewitt Springs. The wine this vineyard produces is what we believe to be a true expression of a McLaren Vale Shiraz. The vineyard is protected from the harshest winds coming from the Southern Ocean but still benefits from the cooling breezes that allow for a long, slow ripening period. This helps maximize colour and flavour development and enhances the quality of the fruit that goes into this wine.
