If you are attending i4C – the International Cool Climate Chardonnay Celebration July 16 to 18 in Niagara – I hope to see you there!  If not, I still bring you the very best Canadian chardonnays being poured at this event, in my opinion.  You can order them direct from the wineries by following the Purchase links.

I bring in contributor Janet Dorozynski to help set the scene for i4c 2026. She published a full feature at WineAlign last month.  And I also direct you to the official coolchardonnay.org  website for details on the myriad events, tickets and directions if you need last minute guidance. It is a great three-day event, now in its 16^th year.

Excerpt from Seriously Cool I4C by Janet Dorozynski

“Each July, the International Cool Climate Chardonnay Celebration, or i4C, brings together chardonnay winemakers and wineries from Ontario, across Canada and from leading wine regions across the world where chardonnay shines.

Since its inception in 2011, i4C has welcomed over 271 wineries from eighty-five cool climate wine regions, pouring 1863 different cool climate chardonnays. i4C is not a competition but rather a celebration of cool climate chardonnay, with multiple events taking place over the course of the weekend, in vineyards and other unique venues across Niagara. 

The inspiration for i4C can be traced back in 2009, when Le Clos Jordanne 2005 Claystone Terrace chardonnay beat wines from Burgundy and California in a blind tasting in Montreal. The result sparked a collective objective among Niagara winemakers to restore what they called “the dignity of chardonnay” after years of the ABC movement, and the desire to position Niagara as a global center of excellence for chardonnay. This vision has been realized as the region has earned considerable international recognition as a producer of excellent cool climate chardonnays”

This year marks the 16th Anniversary of i4C and features an expanded coast to coast Canadian theme. Expect perennial Ontario favourites like Hidden Bench, Tawse Winery, Bachelder and Domaine Queylus alongside wineries from British Columbia (Quails’ Gate, Tantalus and Joie Farm) Quebec (Vignoble Camy) and Nova Scotia (Blomidon Estate), in addition to chardonnay producers from France, Italy, South Africa and more.

There is of course a certain irony that i4C often takes place during some of the hottest days of July. But perhaps this corresponds with the expansive definition used for cool climate chardonnay. At i4C you can taste chardonnays from warmer climates that are “cool by coastal effect”, that is, influenced by ocean or inland bodies of water, along with those that are “cool by continental effect”, from regions with shorter, warm to hot growing seasons. There are also chardonnays that are “cool by latitude” from northerly regions like Burgundy and those which are “cool by attitude” where, regardless of origin, point to the influence of winemaking decisions in shaping the freshness and texture that characterize many of the world’s finest chardonnays”

Chardonnay’s Leading Place in Canada

Canadian chardonnay is cooled foremost by latitude – 49-50 degrees in B.C.; 42 to 44- degrees in Ontario, 45 degrees in Quebec and 47 degrees in Nova Scotia.  But thereafter water proximity plays a huge role.  B.C. is also cooled by altitude but mostly by the presence of the large very deep (maximum 230meters) Okanagan Lake, or the Pacific Ocean when considering Vancouver Island, neither of which ice over.  Ontario is cooled and moderated by the Great Lakes, primarily Lake Ontario which has an average depth of 86 metres and doesn’t freeze either. Quebec is somewhat moderated by the St. Lawrence and Ottawa Rivers and some impressively large local lakes.  And, of course, Nova Scotia is cooled by the massive influence of the North Atlantic and the Bay of Fundy.  So, chardonnay makes sense right across country with plenty of room for variation based on soil types and topography.

Chardonnay is the largest production white vinifera grape in Canada.  In B.C. it leads all other white grapes with 1,083 acres (2026) accounting for 12% of province’s production.  In Ontario it is farmed on 1,875 acres accounting for 18% of overall production, the largest share of any vinifera variety white or red.  In Quebec, which is dominated 80% by winter hardy hybrids, chardonnay is the largest vinifera planting, but only 6% of the vineyard.  The situation is very similar in hybrid dominated Nova Scotia. 

Where is it being chardonnay made the best?  There is no clear answer to that, other than perhaps, everywhere. For proof we turn to the results of the WineAlign National Wine Awards of Canada. The 2026 Chardonnay results were heavily skewed to Ontario thanks to the lower-than-normal entries from B.C. as a result of severe damage to 2024 crop.  The better indicator is the 2025 Awards where there were 94 chardonnay medals overall. B.C. took 44 (including all 4 Platinum medals) and Ontario took 45, with three going to Quebec and two to Nova Scotia. Almost a dead heat.

The top tier chardonnays reviewed in this article are from some of the oldest chardonnay vines in the country, in both B.C and Ontario, some as far back as the mid-1970s.  Vine age lowers yields and builds better structure and flavour concentration.  By the way, the first Chardonnay labelled wine in Canada was by Brights Wines in 1955, after the variety showed well in post-war viticultural trials. One of the first commercial plantings was near Beamsville just a few later by the Lenko family. 

So here you go – twelve great Canadian Chardonnays (including two Blanc de Blancs sparklers) that are being presented this week at the International Cool Climate Chardonnay Celebration. Some are actually debuting at 14C. Most are from the 2023 vintage, which was considered excellent in both B.C. and Ontario. In fact, I think that it has made some of the best Ontario chardonnays I have ever tasted. 

And please note, I have not reviewed the superb Tawse 2023 Chardonnays – Robyn’s Block, Quarry Road and Estate – below. They were fully reviewed as part of the Tawse profile June 25, so the reviews can be easily searched.
