Amalie Robert Estate Climate Update: 2011 Mid-October
"Harvest - the final act of farming. Our mission is to boldly wait out the rains and harvest later than anyone has before." (William Shantner voiceover leads to futuristic orchestra score.)
Hello and welcome to uncharted territory,
This is the 2011 mid-October climate update, our first ever. This year we find ourselves on the verge of an unprecedented opportunity. As of October 15th, we have not harvested a single grape. Sure we have plucked a few cluster samples (more on that later), but the winery still longs for the first of the 2011 vintage.
There is good news to report! Ernie saw his shadow on Saturday afternoon, and for that to happen the sun had to shine. Also, we have minimal bird damage to report, the cover crop is germinating and we have logged a few more degree days for the first half of October.
The signs of harvest are certainly on their way. The Walnut tree is starting to senesce and will eventually turn a brilliant sunburst yellow. Follow this link to learn more about "Why Leaves Change Color." The main harvest tractor is slow to turn over, which means the timing is perfect for having to replace the battery mid-harvest. And the grapes themselves are starting to show the character of the vintage. Yes, we have been sampling.
Sampling is one of the more structured ways we determine when to harvest. The other way is less scientific; we just look outside at the weather. Now there are a couple of ways to go about cluster sampling. Ernie relies on his CPA experience in performing audits. Under this approach, he selects one representative cluster from about every 50 plants which is a 2% sample. If a block has 1,000 vines, he has 20 clusters. Our biggest block is about 2,463 vines, so he has closer to 50 clusters.
The other way to go about this selection process is just to walk a few rows and snip a cluster here or there, but that is really more of a cluster pluck than a randomized sample.
When we get our sample clusters back to the winery we remove the juice from the berries by crushing them in a mesh bag. Right away we take note of the color of the juice. Like most wine grapes the color is held in the vacuoles of the skins. The degree to how easy these vacuoles break open and allow the color pigments to escape is a sign of how ripe the fruit is. Insiders note: Some folks believe color is an indicator of great Pinot Noir. We believe color, like irrigation, is Mother Nature's department and we don't mess with it. But some folks do and they "cold soak" with dry ice (frozen CO2) for a few days to burst these vacuoles and release more color from the skins. The result is a darker hued wine.
Then we smell the juice. It should have a heady aroma, while hard to describe, you know it when you smell it. Then we look at the seeds. Bright green seeds mean you did not trim off the wings. Martini olive green means you are getting close and "Grape nuts" cereal brown means get the buckets, let's harvest!
The next thing we should do is run the numbers, but we are usually a little excited by now and we just taste the juice. Hard to believe Ernie would deviate from his structured approach, but harvest (like the Great Pumpkin), only comes around once a year. The taste of the juice will reveal more about the condition of the vintage than any other factor. We look for sweetness and balancing acidity, but more important are the aromas, flavors and textures on the palate.
The longer those skins can hang, the more interesting and complex the aromas and flavors in the juice and resulting wine will be. This holds true as long as the weather is not too hot, nor the soil too dry, otherwise those flavors can shift over to raisins and prunes. Not too much risk of that this year. Also our evening temperatures have not been so cold as to completely shut down the vine. So we look to the second half of October for a little more sunshine to build some sugars and hopefully desiccate the fruit a little bit.
Here is a quick peak at the numbers. First of all, note that our estimated harvest window was to open on day 289. Day 289 was Sunday the 16th of October and was 105 days past flowering. This is typically the amount of time needed for our flavors and aromas to develop. Good news, we have entered the harvest window.
We have recorded about 53 degree days for the first 15 days of October, providing a total of 1,795 degree days since the beginning of the growing season on April 1st. While we may accumulate more degree days this year, we have exceeded the 2010 growing season degree days of 1,722 by a grand total of 73 degree days. I am told that is not the case in the Dundee Hills where they are lagging last year's degree days.
During the first 15 days of October, our highest high was 73.2 and our lowest high was 68.4. Our lowest low was 41.7 and our highest low was 43.9 degrees Fahrenheit.
There was a significant amount of rainfall during the first 15 days of October. We have logged 2.54 inches of rain so far this month. However, that is well short of the 6.22 inches of rain logged in October 2010. This is either a blessing in disguise or something more to look forward to.
Rainfall since April 1st through October 15th is 11.93 inches, and is 11.16 inches less than last year's growing season rainfall of 23.09 inches. The average monthly humidity was 79.61% and the average dew point was 47.87 degrees.
In summary, the 2011 vintage is one of those rare years where we are getting some really nice aroma and flavor development in the skins with unprecedented hang time. Through September the summer was moderate and dry. The weather, while cool and damp during the first part of October, is holding the botrytis at bay and allowing the fruit to continue to develop. We are seeing lower sugar levels that will result in lower alcohol wines. We think 2011 defines "Cool Climate" viticulture and is the reason why we selected the Willamette Valley to grow Pinot Noir. With all of the "press" surrounding this vintage, has anyone really done the investigative journalism necessary to interpret the epic potential we are experiencing? Well, maybe Dana Tims is onto something here.
Moving right along, how does this translate into wine? The first thing to understand is that each and every one of our roughly 600,000 Estate grown clusters is a little bit different - Mother Nature wouldn't have it any other way. We do the best we can all year long to care for them and then make a selection of which ones to thin off the vine so that the rest will ripen their seeds and mature.
As harvest approaches we see that some of the clusters are not going to make the final trip to the winery. For whatever reason, and there are several, some clusters will get left behind. Last year, the birds took a few of our most prized berries and the deer can also have an impact. But the main reason we leave some of the fruit behind is botrytis, aka "bunch rot."
When we see a cluster that looks a little furry, it is rejected at the harvest bin. This is where our first sort has always taken place. The rule is sheer simplicity - "If you are not willing to put it in your mouth, get it out of the harvest bin." It's just that easy!
We think of our entire vineyard as our super set and the clusters we accept into the winery as our subset. The difference is the fruit that is cluster plucked out. At the end of the day, they will decompose providing nutrition to the vines for next year. What we are left with is our selection of the best fruit from the vintage.
Once in the winery, we take another look to insure we are bringing in clean, healthy and mature fruit. We are diligent in reading the ripeness of the stems for our whole cluster fermentations and, as always, we let the yeast from the vineyard ferment our Pinot Noir. We believe our job is to preserve the character of the vintage so when you open a bottle years from now, you can say, "Oh yeah, I remember 2011. Nice!"
In closing, we think back to how we found our vineyard. It was covered with cherry trees in bloom. Ernie said, "Well Bob, it looks like you have your orchard on top of my vineyard." Our definition of luck was, "When opportunity meets a prepared mind."
This year marks our 10th harvest. Certainly we have not seen it all, but we have seen enough to know that in farming "It is better to be lucky than good!"
Thank you all for the positive comments and a special nod to everyone who has been doing the "sun dance."
Kindest Regards,
Dena & Ernie
