Canada's coolest recognised wine region, where the eastern rain shadow of the Vancouver Island mountains creates pockets of viable viticulture. The Cowichan Valley concentrates most serious activity; thin soils over rocky glacial till, maritime breezes, and long summer days produce wines of unusual tension and aromatic delicacy. Pinot noir, pinot gris, ortega, and bacchus thrive; Bordeaux varieties are a struggle.

Vintage assessments

Year	Rating	Notes
2024	93	Vancouver Island's 2024 was extraordinary — one of the warmest, driest seasons on record for this maritime wine region. Cowichan Valley and other sub-regions produced Pinot Noir and aromatic whites of remarkable concentration and quality.
2022	91	Vancouver Island's maritime climate — cool, wet, fog-moderated — produced wines of extraordinary delicacy and precision in 2022's warmest season in memory. Pinot Gris and Ortega shone; Pinot Noir from the Cowichan Valley achieved unprecedented ripeness without sacrificing the island's signature freshness. Blue Grouse and Zanatta both produced their finest recent vintages.
2021	83	The heat dome moderated significantly by the Island's Pacific exposure. Cowichan Valley recorded peak temperatures 8–12°C below mainland Okanagan during the June event. Pinot Gris and aromatic whites excelled; Pinot Noir more variable. The island demonstrated its natural heat moderation capacity.
2020	87	No smoke, consistent maritime season. Vancouver Island's insularity from the mainland fire events meant 2020 was a clean, balanced vintage. Ortega and Marechal Foch showed strong results. Cowichan Valley's certified organic producers had a benchmark year.
2014	91	Vancouver Island's 2014 season benefited from one of the driest, warmest summers on record for the island. Pinot Gris, Ortega, and Pinot Noir achieved impressive ripeness, producing wines of unusual concentration for this maritime-influenced region.
2013	91	Vancouver Island's 2013 season was remarkably warm and dry by island standards — the Pacific climate produced wines of unusual concentration and aromatic intensity for this cool maritime region.
2012	88	Vancouver Island's 2012 was one of the warmer seasons on record for this maritime region. Pinot Noir and Pinot Gris both achieved good ripeness, though the harvest was complicated by late-season rain on some sites.
