Washington State Harvest Begins

Grower beats earliest pick by two days in the Horse Heaven Hills

Prosser, Wash.—The solid accumulation of heat units means vintners are hitting the trail to vineyards the Horse Heaven Hills a few days earlier than usual this year to round up ripening grapes.

Crews picked clusters of Marquette at Paul Champoux’s vineyard last week, while Mercer Wine Estates logged what looks to be the earliest-ever harvest of Sauvignon Blanc from its vineyards Tuesday (Aug. 26).

“We’re about four days ahead of where we were last year,” said Rob Mercer, president of Mercer Wine Estates.

The previous benchmark for an early harvest was Aug. 28, but warm temperatures and clear skies saw the tally of growing degree-days hit 2,538 as of Aug. 24, putting the AVA on track to top the long-term average of 2,989 and perhaps even the 2013 tally of 3,164 (state-wide numbers are available via Washington State University). 

Mercer expects to harvest Sauvignon Blanc for its own wines (and potentially Pinot Gris) once September arrives. Grapes picked this week came in at approximately 21º Brix, while Mercer prefers something closer to 23º Brix for its own wines.

Though it doesn’t take the good weather for granted, the season to date is allowing Mercer greater leeway with scheduling and handling of its grapes.

“We try to be consistent with our style, so in a warm year like this we definitely have the ability to hang the fruit for a little bit longer,” Mercer said. “We have a little more flexibility to take stuff at its premium, and we’re not quite as bunched up toward the end of the season.”

“The yield expectations are in line with long-term averages, and things look good. So there doesn’t appear to be any reason to feel things are going to be short at this point,” he told Wines & Vines.

Similarly, Ali Boyle expects harvesters to start bringing in Sauvignon Blanc for Alexandria Nicole Cellars as early as this weekend. While summer rains provided some concern regarding mildew, the famous winds of the Horse Heaven Hills swept away most of those fears fairly rapidly.

“If anything we were worried about things being a little too heavy this year,” she said. “It’s a good problem to have.”

Linda Trotta, winemaker at Swiftwater Cellars in Cle Elum, expects to receive her first grapes (Chardonnay) around Sept. 11, followed by Merlot and some early Syrah.

Swiftwater sources grapes from the Horse Heaven Hills, Walla Walla and Red Mountain AVAs as well as the Yakima Valley.

“Things will probably get going pretty quickly once we get started,” Trotta said. “It’s actually pretty much the same timing as we saw last year, which is a little bit surprising for us, because things were at least a couple of weeks ahead until we got that extended heat wave that extended into véraison, and I think that shut things down.”

Yields promise to be average, with some sites in Walla Walla that were set to deliver heavier crops lightened to ensure even ripening.

All told, the Washington wine industry is expecting a 230,000-ton harvest this year, according to the Washington Association of Wine Grape Growers, and Mercer said demand seems in line with what’s shaping up to be a record volume.

“There’s more demand than there is supply, and so pricing is good both on the raw grape side and on the wine side,” he said.

Mercer itself planted an additional 400 acres this year, approximately 300 acres of which are Cabernet Sauvignon, with the remainder dominated by Syrah.

Cabernet Sauvignon is now the most widely planted grape in the state, and Mercer didn’t make any apologies for planting hundreds more acres.

“There’s a lot of Cabernet drinkers in the United States,” he said. “Washington state Cabernet has had a great presence out in the market.

“Everything is lining up with what the expectations are, and we can do it for a price point and value that’s hard to compete with,” Mercer said.
