I see Cabernet Franc as a versatile and highly regarded grape variety, but in Ontario, it is often overlooked for its more widely known counterparts for consumers, leading it to be more used as a blending grape versus a single varietal bottling. With that said, Cabernet Franc has found a home in Ontario's cool climate. This grape is known for its adaptability and ability to thrive in unpredictable weather conditions, which we discuss below.
History and Origins
Cabernet Franc originated in southwest France, specifically in the Libournais region, and was later introduced to the Loire Valley in the 17th century. This introduction is often attributed to Cardinal Richelieu, who transported cuttings of the vine to the Loire Valley, where they were planted at the Abbey of Bourgueil.
By the 18th century, Cabernet Franc had become well-established in regions like Fronsac, Pomerol, and Saint-Émilion. More over, it is one of the parent grapes of Cabernet Sauvignon, having crossed with Sauvignon Blanc to produce this popular variety.
Today, Cabernet Franc is grown in numerous regions around the world, such as:
France: Predominantly found in the Loire Valley (Anjou, Bourgueil, Chinon, Saumur-Champigny) and Bordeaux (Saint-Émilion, Pomerol).
Italy: Significant plantings in Friuli-Venezia Giulia and Tuscany (Bolgheri).
Spain: Grown in Castilla-La Mancha and Catalunya.
Hungary: Successful varietal examples from Villány and Szekszárd.
Canada: Planted in Ontario's Niagara Peninsula, Prince Edward County, and British Columbia's Okanagan Valley.
Argentina: Producing high-quality wines in Mendoza.
United States: Found in Washington State, California, Oregon, New York (Finger Lakes), and Virginia.
Chile: Planted in the Central Valley (Maipo).
Australia: Limited plantings in cool climates like North-Eastern Victoria and the Adelaide Hills.
New Zealand: Small plantings due to the cool climate, which often results in Cabernet Franc-like flavours in Cabernet Sauvignon.
Characteristics and Styles
Cabernet Franc is an aromatic, red berry, tomato, and herb kind of wine. One of its tell-tale signs is notes of bell pepper or jalapeno, depending on where the grapes are grown. You will also find lively acidity and moderate tannins in this wine giving it the style profile fit for any meal on a patio.
Growing Conditions in Ontario
Cabernet Franc's early ripening trait and adaptability, as mentioned above, allows it to thrive in the Ontario's sinewy growing environment. Here's a list of Ontario climatic considerations that work in Cabernet Francs favour:
Temperature Adaptability
Cabernet Franc is remarkably adaptable to temperature fluctuations. It thrives in a wide range of temperatures, from the cool climates of Ontario to warmer regions like California. The ideal temperature range for its development is between 15°C and 25°C, but it can handle temperatures up to 35°C during the growing season. With uncertainties of climate change, this grape handles the temperature swings when given the proper care.
Rainfall Tolerance
Cabernet Franc prefers moderate rainfall, typically between 500 and 650 mm annually. This helps prevent water stress and reduces the risk of fungal diseases, which are common in overly wet conditions. This state makes Ontario ideal, as the province experiences 527.3 mm of rain per annum.
Early Ripening
Cabernet Franc ripens earlier than many other varieties, such as Cabernet Sauvignon. This trait allows it to mature before the onset of autumn frosts, making it well-suited to cooler climates with shorter growing seasons.
Ontario Producers to Look For
Cabernet Franc plays a crucial role in Ontario's wine industry, representing over 20% of all red grape plantings. Cabernet Franc's prominence in Ontario is not only due to its extensive plantings but also its versatility in winemaking, allowing it to be crafted into a range of styles from varietal wines to complex blends.
While personal choice dictates any recommended list, here are a few notable Ontario producers of Cabernet Franc to be aware of:
