FIELD NOTE 01
Scope of vinifera
In Ontario, focus grapes include Chardonnay, Riesling, Pinot Noir, Cabernet Franc, and Gamay. In BC, Merlot, Pinot Gris, Shiraz, and others are added. Pairing region and variety — not just the country — reveals the range for both reds and whites.
FIELD NOTE 02
Role of interspecific hybrids
Vidal is an important variety for Icewine. In Quebec and Nova Scotia, hybrid varieties with cold hardiness such as L’Acadie Blanc are also important. Being a hybrid does not automatically mean the wine is sweet or low quality.
FIELD NOTE 03
Separate variety and production method.
The variety name Vidal and the production method/category Icewine are different things. Similarly, Chardonnay is used both for dry still wines and for traditional method sparkling wines. By adding columns for region, residual sugar, fermentation vessel, and maturation to a variety comparison table, you can compare and taste.
Not determined by grape variety name alone. Confirm Icewine labeling and production method separately.
PAUSE & REFLECT
Check your understanding.
If Vidal is written on the label, is it always Icewine?
