I have a small vineyard growing behind my house in Seattle. Seattle is certainly on the cool side for wine grapes, but my plot is on a west-facing slope, so it’s relatively sunny. And I planted mostly a cool-weather varietal, Regent. Regent makes a rich, red wine.
Currently I have 14 producting Regent vines, 6 more planted; and 4 Dolcetto vines (which need a little more heat, so they’re experimental). They’re planted in two rows with high density (3×4 spacing). My hope is to get 7-10 gallons of fruit once they’re all mature.
The first crop last year was small — due to vine maturity and a late freeze — but the wine (just finishing MLF phase) is excellent: dense, fruity, dark. I did an extended maceration and a couple of weeks after fermentation was complete, it was acidic and tasted very much like blueberry wine. Since then, it’s settled down and has a strong Bordeaux character.
