The cool, wet start to Oregon’s growing season has pushed the wine grape harvest back a bit.  Winemaker Sam Tannahill says the recent turnaround to hot summer weather is unusual, too. But he says things are looking good to be well into the harvest in the north Willamette Valley by the third week in October. As for what this year's vintage will bring Tannahill says he doesn't know, but that's the interesting part of making wine.
