Hello
and Welcome,
May is
the month the vines get busy and in turn the vineyard hands get busy with vine
shoots and trellis wires. Miles and miles of vineyard trellis wires. In our
vineyard construct, we run about 9 miles of trellis wires per acre. With each
and every shoot perfectly tucked in by hand. That ought to hold ‘em till
harvest.
Ernie
spent most of April dodging raindrops and getting the vineyard floor turned,
tilled and seeded for the summer with a cover crop mix of Buckwheat and Vetch –
a timeless combination not unlike Pommard and Wadenswil.
“Owners/winemakers
Dena Drews and Ernie Pink have always marched to their own beat, opting to release
their extensive range of wines after they have had some bottle age.” – Josh
Raynolds, Vinous, June 2019
Now it
is the vines’ turn to take the lead. With plenty of soil moisture and warm
temperatures in early May, the vines took the advantage and played right into
our viticultural plan. You see, while Ernie was out burning diesel, the
vineyard crew was preparing for this very event. Their task in April was to
count to 12, on about 50,000 vines.
Deep
Dive - Vine Shoot Spacing
This is
our “deep dive” into vine shoot spacing and the number 12. First, lets review
the mental construct that precludes the number 12 and that is vineyard spacing.
Yep, we are talking about vine density or vines per acre. The next time you
look out into an open field try and visualize 43,560 square feet. That’s an
acre. Or when the NFL comes back on, that football field is 1.32 acres
including the endzones.
Or you
could do it the Ernie way. He decided that the most optimal vine spacing on our
dry farmed sedimentary Bellpine series soil would be 7.5 feet for the tractor
row and a cozy 4 feet between each vine. That provides us with 1,452 vines per
acre. Using farmer math, we can break that down like this.
First,
we start with our acre of land, 43,560 square feet. Then we divide that by our
tractor row spacing of 7.5 feet and that gets us to 5,808 lineal feet of vines
per acre. Said another way, an acre is a strip of land that is 7.5 feet wide
and 5,808 feet long. A quarter mile race track is 1,320 feet long, so a mile
would be 5,280 feet. Ergo, we are 1.1 lineal miles per acre. That becomes
important next month when we talk about a fully functioning canopy, aka our
solar array.
So what
we do is break up that 5,808 lineal feet into a vine at every 4 feet. Logically,
5,808 divided by 4 gives us the magic number of 1,452 vines per acre. There is
a little more math left to go, so if you are starting to feel some swelling at
your frontal lobe, this would be the right time to break out the duct tape and
apply a few wraps.
As most
of you have no doubt figured out, each vine has 30 square feet of soil to
colonize. It has 2 feet each front and back and 3.75 feet side to side. The
only variable is effective rooting depth. Ask Ernie about rootstock growth
habits sometime. Or just wait until the August drought for the rootstock “deep dive”.
Right,
back on point. The trellis system we adopted for our vineyard construct is
called Vertical Shoot Positioned or VSP. And we employ a single Guyot, because
he couldn’t find a date. Actually, that is a farming term we will get to soon,
relatively speaking. When you train vines to grow into a trellis system, which
you have to do each and every year as they seem to have the attention span of a
gnat, you have to decide on cane pruning or cordon spur pruning.
In the
last best place to grow Pinot Noir, we choose to cane prune. This means we take
a (smart) shoot from last year that was successfully trained to grow into the
trellis and wrap that on the fruiting wire which is conveniently located 30
inches above the vineyard floor oriented (not orientated) in a horizontal
plane. This is so that the new shoots can be trained to grow vertically into the
trellis system until they reach a total height of 90 inches at which point
Ernie goes out and hedges their shoot tips off. That’s our canopy, it’s 60
inches tall starting at 30 inches off the vineyard floor and tops out at a
solar radiation maximizing 90 inches. Assume 18 inches thick and for each 48
inch long, single Guyot that makes 51,840 cubic inches of canopy, or 30 cubic
feet. That’s the same soil footprint at 1 foot deep. Hmmm…
We are
going to bring it home now. When you wrap a cane onto the fruiting wire the
cane is called a Guyot. In our vineyard construct we have 4 feet between each vine
and choose to run a single unidirectional 4 foot Guyot, mostly. While it wasn’t
obvious at first, Viognier does not like a single, unidirectional 4 foot Guyot.
So we tried a double, bi-directional 2 foot Guyot, but not much better. How
about a double, bi-directional 3 foot Guyot, happy now? Yes, I like that. Very
good.
A
cordon is what they typically use in the Napa-Sonoma Nebula. It’s as if someone
put down a cane one year and forgot to prune it back the next. For those of you
who don’t know, Cabernet Sauvignon is the galactic faux pas that was created
when Sauvignon Blanc met Cabernet Franc in Bordeaux. It’s a different world in
a galaxy far, far away.
On each
Guyot, there are several buds that will push shoots that in turn will produce
clusters of wine berries. From a wine quality point of view, we would like to
have enough space between each cluster for good air flow and sun exposure. That
means we are looking for about a 4 inch space between each shoot distributed
equally along the 4 foot cane. We want 3 shoots per foot of cane times 4 feet
of cane. Aha! That’s how we get to 12. So easy a winemaker can do it!
The
vines could care less. Sometimes there are 6 or even 8 shoots per foot of cane.
Sometimes a shoot will have a double shoot that grows right next to it. Imagine
an aerial view of any interstate in the USA. Those cars are not equally
distributed along the road. And then there is the guy in the far left lane
doing one mile an hour over the posted speed limit. The spacing behind that car
is short, and over time will come to reflect the temperament of the following drivers.
So,
that is what the vineyard hands were doing in April. They were out there
equally distributing 12 shoots along a 4 foot cane, about 50,000 times. And
what about the epicormic buds? Yeah, we take those suckers off at the same
time!
During the month of May we have the vines right where we want them, growing into the trellis wires! And they are getting some help from a team of specially trained vineyard workers. Now get this, since there were only 12 growing points and not 25 or 30, the shoots grow faster and that makes it much easier to catch them in the trellis wires.
Surface the boat! The deep dive exercise is concluded.
Farm
Equipment
It
wouldn’t be May without an appropriate tribute to farm equipment. “Hey, is that
a new battery cable? Looking good!” Most every corner of the wine growing
planet has produced some form of wine growing equipment. Some more useful and
certainly more reliable than others. As Ernie has lamented frequently, all
three of his tractors are of the Italian persuasion, oh joy.
The
hedger is French and mounts on one of the Italian stallions. After 20 years,
they have worked it out. The flail mower is made domestically, by an Irish founded
company. The rototiller, which is as tough of an implement as you are likely to
find, is German. Jawhol!
That
leaves the vineyard sprayer, which comes from our good friends up north in Penticton,
British Columbia, Cehnehdeh. You see up north, “a” is pronounced “eh”. Ernie
had to buy a new sprayer a few years back. It was the same manufacturer and he
just upgraded to the latest version. While this may sound kinda funny, farm
equipment does evolve. Better components, larger tanks and more money.
“What
the hell is a sprayer?” We hear you. Check out this vintage advert for sprayers
in 1924. Some were designed for the horticulturists of the day to apply some sort
of airborne mixture to a rose bush. The goal is for the ejecta (in a water
vapor form) to land on the rose bush and prevent mildew or other nefarious
insects from taking over.
While
the modern-day implementation may have changed, the goal remains the same – to
prevent mildew from growing on your bush.
The
gentlemen of the day, however, appear more concerned with other, more pressing
matters.
For
roughly $25,000 CDN, you too can purchase a device that will apply an airborne
mixture of sulfur and water to prevent mildew from growing on your horticultural
bush or agricultural crop, such as wine berries. Water is simply the delivery
vehicle to get the sulfur onto the vines. Much like French fries are a delivery
vehicle for ketchup. And yes, sulfur is organic, but we are not so sure about
the ketchup.
When
you purchase a new piece of equipment, you are buying “time”. While there are “all
kinds of time”, there never seems to be “enough time”. As in “productive time”
without “down time”. “Over time” as equipment depreciates, it begins to offer
the Master Farmer “some time” to reverse engineer its inner workings.
While
Occam’s razor is a fine tool to be implemented in most situations, it is rarely
applicable to farm equipment. Much better tools are hammers (in a range of
sizes), the internet, telephony and electronic payment processing capability.
And speaking of “buying time”, there is Next Day Air.
Farmers,
while generally risk adverse people in their non-farming lives, are also
somewhat impatient. As in “this needs to be done now before the rains or hail
or birds arrive”. Hence the TLA (Three Letter Acronym) RFN which stands for “Right
Farming Now”. Pick your pestilence, in any given agricultural endeavor at any
point in the growing season, but especially harvest, and you will see the true
metal of a Master Farmer shine through.
In
Ernie’s case it was 24 hours from the problem detection point until returning
to productive time. Pretty good, really. But the protocol is very simple. The
first step is identifying you have a problem. That was the easiest step, as one
side of the sprayer was spraying the vines and the other side was not. Ok,
that’s a real and verified problem.
The
second step is to determine why the problem is occurring. Since the valves on
the sprayer are all electronically controlled, Ernie focused on tracing power
through a variety of fuses, connections, switchboxes, relays and solenoids,
most of which were not designed for easy access. It’s an Italian tractor pulling
and providing the power to a Cehnehdiehn sprayer.
After
consulting the owner’s manual, which was actually written in American English,
performing a set of tests, and leaving 2 messages with the manufacturer, it was
time for lunch. Lunch lasts just as long as it takes for all of the second step
activities to gel into a plan of action. Then it is back on the phone to the
manufacturer.
“Well,
it could be …” Yes, of course it could, and I just saw a unicorn run by. After
getting a matrix-like download on sprayer valves, and phone numbers for US
based parts houses that might have inventory, Ernie was on it. But first a call
to the closest parts house. “They are really busy right now. I can take a
message and have them call you back.” Ernie left a detailed message with the
part number he would most likely need. Two days later, there was a call back,
“What can we help you with?” That’s just farmin’ great.
One of
the advantages of newer equipment is that the parts have evolved and become
easier to disassemble, if you have the newer tools that evolved alongside said
parts. Hammers, however, are universal and percussive maintenance has stood the
test of time. An hour later with everything disassembled, cleaned and
reassembled in accordance with the manufacturer’s recommendation, lo and
behold, it still did not work!
Once
the impossible is ruled out, only the improbable remains. After all the
internals were verified, the only possible explanation was the motor that
controlled the valve. Sure enough, it worked one out of three times. Looking
back on it, that one time it did work was most likely sampling error. So, back
to the list of parts houses in hopes the inventory supply chain had functioned
as intended and correctly stocked the shelves with all the right parts in all the
right places.
The
most local parts house was still far too busy to take the call or return the
call from the hour prior. At that point Ernie made a phone in Yakima, Washington,
ring and spoke with Jonathon. It was 3:35 pm. ”Why yes, we have one of those.
We have a bunch of them.” Ernie immediately thought about buying a spare and
just as quickly forgot to do so.
Once
the part was physically verified as actually being in stock, the financial
transaction ensued. Credit card declined? How could this be? Run it again, same
result. “Is this an American Express card? We don’t take that.” New card and we
have success. 3:45 pm.
Yes, I
do want Next Day Air, Ernie confirmed. After the $400 valve motor an extra $25
was gravy for next day delivery. “OK, UPS picks up at 4:00, we should make it.”
Ernie fell silent as he heard the pitter patter of parts man fingers gently
working their magic on the UPS shipping website. “Got it” came through at 3:52
pm. Now the hard part. Waiting to see if it actually arrives. Who remembers
sending off box tops as a kid, only to grow old and unfulfilled?
Miracle
of miracles occurred at 9:55 am the VERY NEXT morning when the most beautiful
UPS truck on the whole planet backed down the driveway. “Here you go, have a
nice day.” Ernie scurried back into the house and with surgical precision
opened the box. It looked just like the valve motor he was trying to replace.
Down to
the shop, a quick tap with the most appropriate hammer and the old valve motor
was off and the new one was on. Now the moment of truth, would it work? Ernie
wired it up, flipped the switch and just as sure as Shinola, it did. Throwback
to the old Microsoft days in Europe, “We don’t ask for miracles; we depend on
them!”
The
Numbers
May
started off on a tear with the first half of the month recording near record
high temperatures. Mid-May transitioned to an influx of rain and cool temperatures.
Were we seeing an ominous preview of harvest 2019? Then the end of the month
came through with more moderate day and nighttime temperatures. Just ideal for
capturing the new vine shoots in our single 4 foot Guyot Vertical Shoot
Positioned trained trellis system - mostly.
May’s
high temperature was 93.2 degrees recorded early in the month on the 10th.
The low temperature for the month was 34.3 degrees recorded on May 1st.
The diurnal shifts in the first half of the month were wider and produced a
higher average temperature of 59.01 compared with the second half of the month
at 57.97 degrees.
Degree Days
for May were 295.3 with the first half of the month registering 161.0 and
latter period 134.3 Degree Days. The growing season to-date Degree Days stand
at 400.3 for 2019 compared with 392.3 Degree Days for 2018. While an 8 Degree Day
difference is measurable, at this stage of the growing season it is
statistically insignificant. Just don’t tell the vines, they are getting ready
to flower.
Rainfall
came mostly during the third week of the month, well before flowering,
registering 1.53 inches, providing a full month total of 1.79 inches. While the
data support no conclusions as of yet, Vintage 2019 is shaping up to be pretty
farmin’ nice.
Kindest
Regards,
Dena
& Ernie
