The Pursuit and the Devotion are the names On Seven Estate Winery gave the chardonnays produced from their Niagara-on-the-Lake vineyard. Those suggestive names were selected to convey the ambition of owners Vittorio and Sula De Stefano, who bought an abandoned seven-acre farm in 2009 to start their own boutique winery.
The couple contracted Niagara-based winemaking consultant Peter Gamble in 2010 to help shape their vision. The site was studied to see which grape varieties would be best suited for the quality they hoped to make and could handle the cold winter temperatures. Then, they patiently waited for the exact type of chardonnay vines from Burgundy to be available to suit the style of wine they wanted to produce.
One of the varieties was Clone 76, a variety with loose clusters and increased mildew resistance to allow the chardonnay grapes to be harvested later in the season, which would mean riper flavours for the finished wine.
The clone was important, but so was the rootstock.
European grape vines are grafted onto different rootstocks, which help protect against bugs that spread disease as well as influence how vigorous the growth and development is. They were after a specific rootstock (SO4), that would be well-adapted to the vineyard’s clay loam soil and help manage the growth of the vine to produce lower yields of better-quality fruit.
“That rootstock allows us to slow down the ripening process,” Vittorio De Stefano says. “We work to reduce the yields throughout the season to get to our target.”

A compromise to plant a different type of chardonnay vine and rootstock would have meant the De Stefano’s could produce wine – and start to make money – on this venture more quickly, but the first vines didn’t go into the ground until 2014.
“I was prepared to make that sacrifice,” De Stefano explains. “There were other options, but it was important to get it right from the start.”
Different varieties of chardonnay vines were planted in 2015 (Clone 95) and 2019 (Clone 96) to give the winemaking team an ability to produce wines with more layers of flavours and complexity. Pinot noir vines were first planted in 2017. The vineyard is certified organic.
The words “estate winery” in its title might give consumers the wrong idea about On Seven’s size. This operation is better classified as a craft winery or a microdomaine, with wines based on the original five acres of vineyard. (An adjacent eight acres added in 2018.) At maximum production, the goal is to make 800 cases of wine – half pinot noir and half chardonnay, which includes some sparkling wine.
“We have expanded to sparkling and rosé because the weather patterns are more extreme now,” he says. “It gives us licence to make the best possible wine each year.”
The slow and focused approach extends to releasing wines. On Seven doesn’t have a physical winery to conduct tours and tastings. Instead, they do an online release in August, releasing chardonnays as three-year-old wines, which allows plenty of time to develop while aging in barrel and bottle before release.
This year’s release features the 2020 vintage of the Pursuit Chardonnay and the Devotion Chardonnay, which represent the best bottles to date from this exciting Niagara winery. A tiny amount of the vineyard’s first pinot noir – only 14 cases, 168 bottles of wine – was snapped up by members of the wine club.
