Hello and Welcome.
This is the 2015 August Climate
Update – Pre-Cluster Pluck Edition
As you read this, “The Great
Cluster Pluck of 2015” has visited itself upon the Willamette Valley,
as has “the greatest show on earth.” And whether you are stumpin’ for Trump or
sidin’ with Biden you have a front row seat to these two wondrous spectacles. As
the late, great George Carlin would say, “Every 4 years these guys get the
runs.”
Harvesting in August, unlike
politicking, is a significant event - which leads to premature fermentation
which is not a significant event. Even car companies wait until September to
reveal their new models and some vehicles too. Historically speaking, people
are picking earlier than any harvest we can recall. And it’s kinda like noses, as
soon as one person starts to pick, everybody wants to pick.
But is it time to pick? We will
explore that topic and more as we shine some light on the topic of Hang Time:
What is it, how do I know if I have it, and what difference, at this point,
does it make? This is a continuation of the “wineversation” that started with
canopy
management and flavor development, progressed into
soils and
rootstocks, delved deep into
crop thinningand available soil moisture and now confronts the final act of wine growing
– the Great Cluster Pluck. This is part of the upcoming Master Class series
offered by the School of Hard Knocks where enrollment is always open.
Hang time can be defined as the
time that elapses while a grower of wine berries and a buyer of wine berries quibble
as to when to harvest. Typically, the grower would like to see the wine berries
harvested RFN (Right Farming Now) before any birds show up to feast upon, or
seasonally rainy weather arrives to rot the crop. The buyer would like to see a
little more flavor development and wait unit the last possible second to
harvest. It is during this negotiated timeframe that hang time occurs and Mother
Nature puts her final touches on the vintage. When the relationship between
grower and buyer becomes untenable, the wine berries will have had sufficient
hang time and therefore may be considered “well hung” and harvest may commence
forthwith. Albeit with a bit of swagger…
Now, 105 days is the average number
of days after flowering that we see great aroma and flavor development in our
Pinot Noir. Since we started flowering on May 31st (Julian calendar
day 151) we should expect our harvest window to open around Julian calendar day
256 (September 13th.) And at this point, that is what Ernie the
winegrower and Ernie the winemaker are thinking. Great minds think alike,
especially when they are housed within the same cranium. And if we need a third
opinion, we turn to guy in the mirror.
All fruits need hang time to
ripen. Some fruits give pretty easy clues as to when they are ready and when
they are not. The ubiquitous tomato is one such be-vined fruit. Oh yes, despite
what classification the follow-on products are, the tomato in all of its
colors, shapes and sizes is a fruit – at least while it is still on the vine.
When the typical red tomato is
ripe it should be, red. We can clearly see in this image that the tomatoes on
offer here are not yet ripe. They are not well hung.
Now if you were growing your own,
you would give them more hang time. But not everybody grows their own: tomatoes
or wine berries. But the tomato, given time and a paper bag, will ripen on its
own. Not so with wine berries, primarily because we ferment them just as
quickly as we can after harvest.
Wine berries are also a be-vined
fruit. However, they do not so easily give up their secrets. Sure they look
purple and are just hanging there ready to be plucked. But should you? Pluck
it? That kinda depends on how much hang time they have had, and what the
upcoming weather pattern holds. Can you get a harvest crew? Tomorrow - maybe?
If not, then you are just hanging’ around, getting a little more hang time.
So to determine how well hung the
wine berries are, and if they need more hang time, we can employ a number of
varying analytical tools. The most primal tool at our disposal is one we share
with creature’s great and small - we eat one. If they are sweet with sugar and
not to acidic, we can give them good marks.
Next we chew the skins and if
they taste like a green banana, that is potassium being released and may
suggest the flavors are not yet fully developed. Then we look at the seed. The
gelatinous pulp of young berries encasing their seeds should be gone. Fluorescent
green means not mature, while “Grape-Nuts” cereal brown means the seeds are
fully mature.
If the wine berries pass all of
the primal benchmarks, then it is time to employ our technical tools. We first
“hunt and gather” a sample that is representative of the block we are
considering cluster plucking. The sample we collect is comprised of entire
clusters and not individual berries.
Long ago the vines made a
concession to the humans that were tending them. You see, it was quite an
arduous task to cut each individual berry from all over the vine. So, the vine
agreed to “cluster” the grapes onto some tendrils that were growing within easy
reach of the humans. You may disagree, but just remember, you weren’t there.
We put the wine berries, still on
the stem, in a mesh bag and slowly but firmly squeeze the juice out of them
into a clean white bucket. We then transfer the juice to a clear glass vessel
and look at the color.
Very pale cotton candy color
tells us that the aromas and flavors are still locked in the skins and are not
ready to be released into the juice. And if they don’t get into the juice, they
won’t be in the wine. A deeply hued mauve indicates that it is time to stick
your nose into the sampling vessel. If a heady bouquet greats your olfactory
senses, then it is time to calibrate the machines.
The pH meter, next to the coffee machine,
is one of the most important machines in the lab. However, it is quite the
joker. Not only does it need to be calibrated every farming day to give you a
true reading of acidity, but it needs to be constantly checked to be sure it is
performing its task with precision. Not unlike the invasive colonoscopy, we
extend the probe into the juice and have a look. While the numbers are site and
variety specific, we like to see something greater than 3 but less than 4 with
two sig-figs.
Then comes the Brix test. The
berries have studied all year for this one and are ready for their numbers.
Brix is a measure of fermentable sugars, and when you multiply Brix by 0.60,
you get an approximate, potential alcohol percent. If you are seeing 20 Brix, then
you are looking at about 12% alcohol – nice for cool climate Syrah. The over
achieving wine berry will register at 25 Brix, or greater, for a potential
alcohol around 15%.
With all of this analysis
complete, it is now time to decide to “go or no go.” Bring them in or leave
them out for more hang time – and live with that decision forever. But wait,
there is more information to consider. Mother Nature has quite a role to play
when you are ready to cluster pluck. A little rain will dilute high sugars, but
may segue to rot. Warm, breezy dry days may desiccate the wine berries and raise
already high sugar levels without commensurate aroma and flavor development. If
you want to make Mother Nature laugh, announce your harvest schedule in
advance.
And then there are the logistics
of harvesting and fermenting. Harvesting at Amalie Robert Estate is done by
hand, vine by vine and block by block. While some of the Pinot Noir in the Willamette Valley is harvested by machine, most is
harvested by hand. And there are only so many hands to go around. So just
because you are ready to go, doesn’t mean that a harvest crew is in your
future. That’s when you say “bucket!” and try for the next day. Is that rain in
the forecast?
Fermenting is not that
complicated. We put 3,000 pounds of grapes in very close proximity with a
little sulfur dioxide and they can take it from there. It is not unlike lining
up all the men in class on one side of the gym and all of the women on the
other. Have them advance until they close the distance between them by half.
Repeat as many times as you like, but they will never touch. However, they will
be close enough for all practical purposes.
The trick though is to be sure
you have enough fermentation capacity for all of the wine you have grown. If
not, you will have to re-use the fermenters, which usually means starting the
cluster pluck a little early, like maybe in August, and bear the shame of
premature fermentation. Then after a few weeks, past the prime harvest window,
return to the field to harvest the remaining crop.
So after a few years at this, we
have determined that the facts, however interesting they may be, are often
irrelevant. It’s fharming dharling and it has its own unique set of realities.
And the reality of 2015 is that
we are on fire! Well, actually that is the neighbors pasture, but you get the
idea, it’s has been hot and dry. But turning the corner we are. Despite the
Hell-bent for Leather growing season to date, September brings with it shorter
days. And it would seem that the forecast suggests cooler day time temperatures
and lows all the way down into the 40s. And that, coupled with the late August
and early September showers, means a little more hang time for the dry farmed
wine berries at Amalie Robert Estate.
This is the part of the Climate
Update where we switch from the random character generator (RCG) to the random
number generator (RNG.)
We have recorded 565.9 degree
days for the month of August, providing a total of 1,997 degree days since the
beginning of the growing season on April 1, 2015. Our high temperature was
103.0 degrees and our low temperature was 43.2 degrees.
This represents a trajectorial
shift from 2014 which recorded 615.2 degree days and had accumulated 1,886
degree days through August, but finished up the growing season at whopping
2,499 degree days. The difference seems to be that 2014 started cooler and
finished in a blaze of glory, while 2015 started hot and may finish with a
long, cool ripening period yielding very well hung wines. Could the 2015
Hell-bent for Leather vintage turn out to be Delish?
With 0.59 inches of rain arriving
on the 28th of August and a bit more on the way for the beginning of
September, it could happen. Unless you have already plucked your clusters, and
if so, well, there’s always next year. We have endured 88 consecutive days
without rain, and that is quite a dry spell for us. The last rain event of 1.24
inches was recorded on the morning of June 2nd. Our growing season
to date rainfall is 4.53 inches.
And so we do what farmers do – we
keep ourselves busy running the numbers until we see the “steal home plate”
sign from Mother Nature. We gotta admit, she looks pretty good in a ball cap; all
that red hair flowing in the gale force wind and driving rain.
September, gird thee loins, for
we intend to reign harvest down upon you!
Kindest Regards,
Dena & Ernie
