Harvest Report October 26th 2013

The last week has seen a shift in growing conditions in eastern Washington with nighttime temperatures cooling significantly and precipitation falling in a number of areas. The former is particularly significant as one of the hallmarks of the 2013 growing season has been warmer than average nighttime temperatures. This should lessen the sense of urgency that some winemakers have had.

“Ripening should be slowing considerably,” winemaker Chris Peterson of Avennia said. “Most warm site Cabernet is being scheduled for the next week or two. However, now with the cool down that seems to be on the horizon, cooler site Cabernet could be afforded considerable hang time.”

Peterson, for one, is excited about the prospects that these changes bring. “If the pattern holds like it should, we could be in for a classic year,” he said, noting that he was particularly excited about the possibilities for cooler site Cabernet Sauvignon.

At Januik Winery and Novelty Hill, winemaker Mike Januik was also glad to see the temperatures drop. “I look forward to this time of year because we don’t feel like we have to get something picked tomorrow,” he said. “We can wait three or four days and it will probably benefit us.” Januik noted that he has brought in 40% of his fruit so far and expects to be done in about three weeks. “We’re going to be pretty busy here,” he said.

While the past week’s rain has delayed harvest in some cases, few seem particularly concerned. “If it says it’s going to rain, half the time it doesn’t,” Januik said wryly. “When it does, it usually just sprinkles and then a wind picks up. It’s more of a nuisance than anything else.”

While 2013 has been a warm, early harvest in Washington, some are not seeing the sugar accumulation that might be expected with hot summer temperatures causing vines to shut down.

“The sugar levels this year, at least so far, are very modest for such a warm year,” Chris Peterson of Avennia said. “To get Grenache and Merlot with ripe flavors under 26 brix is unusual in my experience. Most Cabernet samples have been similarly lower.” Peterson noted that, overall, brix levels are generally lower than in 2012. However, he noted that the warmth has had its effects, saying, “The acid levels, however, are quite low.”

In some cases, the effects of the warm temperatures on harvest have been stunning. James Mantone at Syncline Wine picked some of his grapes as much as 30 days ahead of last year’s pace. However, he said that brix levels have generally been lower.

“What was startling early on was the fact that we had brown seeds and the beginning of stem lignification at the lowest brix levels I have ever seen,” Mantone said. “Flavors came on early with incredibly dark colors. This allowed us to pick a number of Syrahs with great acids, low pH’s and alcohols in the low to mid 13s.”

However, Mantone noted that the effects of the warm growing season have been vineyard and variety specific. “Some vineyards developed great flavors at lower brix and great natural acidity, especially warm site Syrahs which seem to have undergone veraison in the most uniform and rapid manner I have ever seen,” he said. “Other vineyards/varieties were marked by the most uneven veraison I have witnessed in years.” In terms of the latter, Mantone noted that Grenache has seemed particularly affected.

For Mike Januik at Januik and Novelty Hill, the anomaly this year was picking fruit in August. “This is the first time in 16 or 18 years that I’ve picked anything in August,” he said. While unusual, he said it was not without precedent. “Back in the early nineties, maybe even late eighties, I was always picking something in August, and then it just stopped for years.”

Januik said of the acid levels in 2013, “We mostly will see lower acids in the places that we’ve picked early but now that it seems to have cooled off, the acids that we are seeing in places like the Wahluke Slope, Stillwater Creek, and Champoux Vineyard are right in what I would call the normal range.”

Head winemaker Juan Muñoz-Oca of Columbia Crest said of the heat, “The one variety that may have suffered the most would be Sauvignon Blanc as we lost some acid in warm sites, but picked some blocks early to balance the wines – the advantages of growing grapes in many different AVAs.”

The warm growing conditions in 2013 have led growers and winemakers to make a number of adjustments in the vineyard and winery. Below are a few winemakers’ thoughts on how they have dealt with the warm growing season.

“The year’s mantra is lots of attention to canopy management and irrigation,” Juan Muñoz-Oca of Columbia Crest said. “We were prepared for the heat from the start as we had an early bud break and hotter than normal early spring. We paid a lot of attention to canopy architecture trying to protect the grapes from the heat, especially the afternoon side of the vine.”

Chris Peterson of Avennia said, “The key for me in such a warm year is to visit the vineyards as often as possible to catch the ripeness at a perfect point for our style, which I would call ‘barely, but definitively, physiologically ripe.’ This is always tricky, as you can’t be out every day, and usually have to schedule picking a few days ahead of time, and things were moving fast in September.”

James Mantone of Syncline Wine said, “We are doing larger percentages of whole cluster ferments – up to 60% – partly because there has been no disease pressure, but also to help maintain more freshness in the wines.”

Mike Januik of Januik Winery and Novelty Hill said, “In a year where there are smaller berries or where you pick a little earlier to find the balance between sugar and flavors, there’s going to be more of a tendency for wines to be more astringent, so we back off in terms of maceration and pump overs.”
