I've built a dozen or so wineries in the south Okanagan over the years, plus the subsequent additions, modifications and renovations. And for a while had a business as a rep for several wineries, selling Canadian wine both in BC and the US. I've learnt that there are as many "good" wines as there are wine drinkers, and the only wine judge whose opinion matters to me... is me.
Because of proximity and longtime relationships, I do favour Okanagan wines. Theyve come amazingly far since I arrived in Canada in 1988, when I mostly thought, "WTF is this weasel p1ss?" The next phase was, "There might be some potential here for cool climate varieties, but they're out on a limb being so far north."
All that is way in the rear view mirror now, and the quality level across the region is impressively high. With climate changing so quickly, what was occasionally possible is now achieved consistently and with distinction. The extreme northern location is now an advantage, and the American producers look at us with envy.
The wines will never be cheap, as there is so little appropriate land available, and the holdings are small and fragmented. Cool climates necessitate low yields to ensure ripeness, and most work must be done by hand because the tiny vineyards aren't efficient for mechanization. But the Okanagan wines shine for value, rather than low price. The whites especially are world class quality but at modest prices when compared to top flight bottlings from Europe and Australia. The reds are in a much more competitive market, the $30 you'll pay for something decent from BC buys a helluva good red from Oz or South Africa or Argentina. No question though that certain Okanagan reds stand up very nicely against comparably priced imports.
Happy to provide recommendations if requested, but opinions are like a$$holes...
