“Shatter happens when it gets too hot. Shatter also happens when temps get below 70 degrees and over 90 degrees. When the temps are below 70 and above 90 and it is too windy then pollination doesn’t occur very well. This photo shows that our crop is good, nice weight, and nice loose clusters. All in all, we have had only moderate shatter and a good fruit set so far.” – David Parrish
A very beautiful, sustainable practice in the vineyard is pollination rows. This is something I just learned in the last year as my knowledge of this industry never stops growing, so I wanted to share about it as we are in the midst of spring time with lupin, mustard, and poppy covered hillsides.
Pollination rows are when we put in pollinating, native plants (wild flowers!) through out the vineyard. The mix we put down is allowed to grow for the majority of the season so the flowers can seed. This then becomes an open invite for beneficial insects such as the praying mantis and lady bug. These wonderful insects eat bad bugs such as aphids and spread the seeds into other rows of the vineyard. So, this creates an overall healthy environment for not only our vines, but the insects we love! Not to mention it’s absolutely beautiful. As you can guess this reduces our need for spraying, which always puts a smile on our vineyard manager’s face. The best part, since we’ve been doing this for years, is that it works very well. It’s a win-win for everyone!
Check out below the photos from last year that we submitted to the AG department. Thank you Linnea of our vineyard management company, Vineyard Professional Services, for sharing these!
Have a great Wednesday!
Quick Fact: Did you know dust brings aphids into a vineyard (or crop)? That’s why we have signs on dirt roads that say speed limits in an attempt to control the dust. Aphids suck nutrients from a plant, which can stunt growth and wilt leaves. An infestation can create havoc and there’s only 4,000+ species of aphids. Cue the “More You Know” jingle.
Bare lines of vines, a coo of a pigeon in the distance, and the crackling of footsteps as a vineyard manager passes through the rows in the morning light. He has done this many mornings, but his steps stop as he notices something different. There it is…light green, soft, even a little fuzzy…it is a bud.
Each year we eagerly wait for bud break to occur. This is when the vines push open leaves much like other plants during the spring. Dormant vines awake when daylight and temperatures increase, which encourages the vines to pull up stored water and macro-nutrients (nitrogen, phosphorus, potassium) from the roots to the limbs. This up-flow of water and nutrients push open the buds. You would think that after leaves push open that it would mean photosynthesis would occur immediately, but it does not. It takes the vine a little bit of time, leaves the size of about silver dollars, before that process begins.
One of the most important parts of bud break is that it is a measurable starting point for the vineyard. We can actually start the clock for when pivotal moments will occur. For instance, we now know we are about 150 to 200 days away from harvest depending on the grape variety. It seems like this then would mean that bud break itself is actually a markable date, but it’s not that simple. This is still farming, which means everything is variable. When bud break occurs depends on a few things. Each terroir is different. And you can probably guess, each variety of is different.
A cooler terroir means that bud break will be later, while a warm terroir like in Paso Robles, CA will have an earlier bud break. In Paso Robles, we have seen buds as early as February. Although for us this year (2018) we are running a little slower as we have had a cooler spring. Each year is different! Another factor is micro-terroir. The difference between locations of vines in a single vineyard will even come into play. A hillside vine will have bud break because of its elevation, but a lower valley vine will still be dormant. Lastly, varieties will have bud break at different times. In our Adelaida Vineyard, our Malbec and Cabernet Franc had bud break first, but the Cabernet Sauvignon hit the snooze button. As you can see, there are many variables that go into this and this is just one part of the vine cycle!
While there are variances in the cycle, one consistent thing is temperature. Vines are very dependent and particular about temperature. Vines prefer gradual temperature increases for bud break, but they don’t always get that. Sometimes they get awoken from slumber with a warming trend and then hit with a freeze. That is why vineyards have tall fans to help with frost protection. A freeze will damage the cellular tissue in the leaves and the leaves will then turn black. It’s awful. This then kills the growth for your year and can sometimes decimate a vineyard. Bud break is basically the infancy stage of the vine. You want to protect it because the leaves are soft and fragile at this stage, much like you would with a newborn (and well, we all know parenting doesn’t stop there). So, that is the one thing all farmers can count on is frost season and the need to be vigilant.
After bud break, we now watch as the leaves begin to grow (obviously). Photosynthesis will begin at a certain point and once that happens the shoots of the vines will really take off as the vines will receive something that they love, much like humans, carbs! Up next is flowering, so stay tuned.
Happy Friday and hopefully this gave you something to think about while you sip your wine…cheers!
We wanted to revisit getting to know our team as Parrish Family Vineyard is very much what it is because of our team. So, here’s your chance to learn more about them!
First up, Lynn Parrish, who is an owner and has been an integral part of the team behind the scenes.
What do you love about Paso Robles?
That it is thriving and growing, but still has that small town appeal.
Where is your favorite spot on the Central Coast?
My home in Creston where we planted our first vineyard (1995). It’s a little slice of heaven.
What are you passionate about?
Any project I tackle be it gardening, work on the ranch, or during the winter months some kind of craft work. And, of course, my 30 year long passion of weight lifting!
How do you take your coffee?
Black in the morning and half-and-half with sweetener in the afternoon.
What is your favorite dish?
Almost anything cooked in a slow cooker.
What is one job you’ve had before that would surprise people?
I was a firefighter for the US Forestry during the summer breaks when I was in college.
What is your favorite family tradition?
Celebrating the 4th of July at our place in Creston down at our little lake.
What is one of your favorite memories at the winery?
When David and I single handedly made our Cabernet Sauvignon in 2009.
Happy Friday all!
With it being Summer, it is definitely a time for enjoying the sun, but as we know too much sun can lead to a dependence on aloe vera and cold packs. This is true for grapes, the sun is an imperative part of grape development, but too much can lead to issues. Grapes depend on the sun for photosynthesis to occur, but too much heat and sun can lead to sun burns, excessive sugar, and lack of acidity. This can result in unbalanced wines with high alcohol. The flip side of this applies as well…too little heat can prompt high acidity and a lack of sugar. Sugar is a necessary part of fermentation in the wine process. As you can see, there needs to be a balance, like in everything, for grape development to be successful and lead to deliciously, balanced wines.
How do you put reigns on a natural part of creation such as the sun? Viticulturists have been using the leaves for years in their vineyards to help facilitate sun distribution, but there is now a shade cloth that can be installed to help create even distribution of light. We recently installed this white shade cloth in our Adelaida Vineyard (Paso Robles) to do just that. It not only has a purpose, but looks really lovely.
I was curious about the shade cloth, so after seeing our new tanks at our production barn (winery) I drove around our vineyard and found a tall man walking down the rows straightening the white shade cloth. It was my dad (David Parrish).
“Pretty cool, huh?” He said with a smile.
“Yeah! It looks great, dad. So, I’m assuming the shade cloth is to protect the grapes from the sun?”
Thus started my dad on the innovation and science behind this white cloth.
It started 10 years ago when my dad was working with Paul Hobbs. He was seeing a need for sun protection, but something that wouldn’t completely block the sun from the grapes. My dad had been primarily working with dark shade cloth for nurseries with his company A&P. So, he began working with a company overseas, but the white shade cloth was very expensive. It wasn’t until a year ago when he found another company that he was able to invent a cloth that would have the perfect weave, exact spaced holes for easy hanging, and it was half the price of the previous cloth. It was also reusable and came on large spools for easy installation. Finally, a perfect match for what vineyards were needing!
So, what makes this white shade cloth better than other shade cloths? There is a science to it and it related a lot to what I know from photography. The white shade cloth helps distribute the light by filtering direct sunlight, but also bouncing reflected light from the other types of sunlight through out the day. This creates more even lighting, which in turn develops more consistent fruit in the vineyard. Therefore:
The viticulturist gets better yield.
The winemaker receives better quality fruit.
The consumer drinks better wine.
A win for everyone on the trail from grape to bottle. So, it is actually a really important piece of innovation that could help the vineyard/wine industry be elevated overall…just with the basic concepts of harnessing light. “Pretty cool, huh?”
After my dad got done explaining all the information to me, I realized that we had bonded over science, which is not something that happens as he is very left brained and I am very right brained. Although, as I write this, we actually embody what wine is…science and art.
