Below is a look at what was picked, when, and where in Washington during October. Many growers and winemakers wrapped up harvest this year between the middle and end of October, although some did pick into November.
The hallmark of this harvest season was certainly the cool down that took place in September and October, where heat accumulation more or less flatlined. This is well shown in the chart of Growing Degree Days (GDD), a measure of heat accumulation, from Washington State University. This allowed picking to occur at a measured pace.
Winemaker Trey Busch of
Sleight of Hand Cellars in the Walla Walla Valley sent along the following table of pick dates over the last three years. For perspective, 2015 was a hot year (again, see the GDD chart above). 2016 had an extremely warm start but then more of a normal(ish) final few months. 2017 had above average heat accumulation during the height of the summer but then cooled down considerably in September and October. Here are Busch's notes:
Block: | 2015 | 2016 | 2017 |
French Creek Chardonnay | 8/19/15 | 8/19/16 | 9/8/17 |
Red Mountain Vineyard Merlot | 9/4/15 | 9/7/16 | 9/26/17 |
Seven Hills Block 33 Merlot | 9/9/15 | 9/12/16 | 9/16/17 |
Red Mountain Vineyard Block D CS | 9/10/15 | 9/28/16 | 10/8/17 |
Les Collines Block 50 Syrah | 9/7/15 | 9/24/16 | 9/23/17 |
Phinny Hill "Elene's Block" CS Clone 8 | 9/22/15 | 9/30/16 | 10/14/17 |
Lewis Syrah | 9/30/15 | 10/7/16 | 10/19/17 |
Blue Mountain Vineyard CS | 9/23/15 | 10/3/16 | 10/4/17 |
Blue Mountain Vineyard Block 1 CF | 9/24/15 | 10/1/16 | 10/11/17 |
CS = Cabernet Sauvignon CF = Cabernet Franc |

As you can see, there is variability in the pick dates across years. While some of the 2017 dates line up with 2016, most are 10-14 days (or more) later.
I'll post additional thoughts on the growing season in a subsequent harvest report.
