Vittorio De Stefano, owner of On Seven winery, has waited 17 years to release the first pinot noir from the Niagara-on-the-Lake farm that he and his wife Sula bought in 2009. Working with winemaking consultant Peter Gamble, the couple studied the seven-acre property’s soil structure to determine which specific clone and rootstock combinations of chardonnay and pinot noir from Burgundy would produce the best possible wine.
The search for the ideal vines from respected nurseries in France took longer than expected. “The thinking was, let’s do this once, let’s do this properly,” De Stefano said.
The existing grapevines were removed to allow On Seven, which takes its name from the size of the estate, to build from the ground up. The five-acre vineyard is certified organic, and an adjacent eight-acre property has been purchased for future grape cultivation.

Clone 76 chardonnay vines were planted 2014, with clone 95 plants added in 2015 and clone 96 in 2018. Those early plantings meant On Seven was able to produce its first commercial release of chardonnay in 2017.
The first pinot noir vines (clone 115) went into the ground in 2017, with an additional planting of two additional clones (777 and 828) in 2019.
Each clonal variation was intentionally selected, De Stefano explained. One of the first official French pinot noir clones available from nurseries, 115 is noted for pinot noirs with balance and elegant character, he said, while 777 yields riper wines with more tannic structure. Clone 828, which is the most recently certified, in 1985, results in more aromatic red wines with fine tannins.
“We had a vision of what type of wine we would get as a result of the characteristics of the clonal and rootstock selection we ordered,” he said.

That vision becomes a reality with the Sept. 13 online launch of On Seven’s first commercial release of pinot noir from 2023. (A pinot noir rosé was produced in 2021. The 2022 crop was lost to winter frost.)
The wet growing season in 2023 meant that On Seven had to reduce the crop to allow the remaining grape clusters to ripen and stay free from mildew and other fungal diseases that would have reduced the quality of the fruit. The total production for the vintage was 71 cases of pinot noir and 86 cases of chardonnay. Pinot noirs and chardonnay made by On Seven 2024 and 2025 are aging in barrel, awaiting bottling for future release.
On Seven is open by appointment and sells its wine online, at onsevenwinery.ca. Its two 2023 releases are reviewed here along with a rare pinot blanc from another family-owned Niagara-on-the-Lake boutique winery that operates without a tasting room.
