Alderlea Vineyards

About Alderlea Vineyards


WineryPrior to 1911, the town of Duncan was known as Alderlea. Now Alderlea has returned as a vineyard and winery. Alderlea Vineyards came to life in 1992 when Roger and Nancy Dosman moved from Vancouver to the rural setting of Vancouver Island's Cowichan Valley. The beautiful southwest sloping 10 acre vineyard, overlooking Quamichan Lake, possesses all the requirements for producing quality grapes. From the rocky soil to the grafted vines recommended by a French research institute, some of Europe's best known grape varieties such as Pinot Gris, Pinot Noir and Merlot flourish in the warm Cowichan Valley summer.


Other quality white wines include Chardonnay-Auxerrois blend, Bacchus, Gewurtztraminer and a dark full bodied red "Clarinet" made from 100% Marechal Foch grapes. Alderlea also produces a dark, rich, port style wine, Heritage Hearth.


Alderlea GrapesWith pride, 100% of our wines, are crafted only from grapes grown in our beautiful estate vineyard. Our white wines are fermented and aged in stainless steel tanks and some French oak barrels, while our reds are aged in American and French oak barrels. Our careful vineyard management and dedication to winemaking produce premium Cowichan Valley wines, full in varietal character and easily enjoyed with a wide variety of cuisine.


Roger grows his own root stock, has an Omega cut grafting machine and has propagated many of his own vines. Roger is currently finding great success with 8 main varieties, while always experimenting to find more grapes for Vancouver Island.
