Wes Hagen: The Joy of Cluster SamplesPosted by Wes Hagen in Untagged |
09/15/2008
By now we’re usually picking. The weather has been some of the coolest I remember in September, which is our warmest month of the year in the Santa Rita Hills. But with all the frost problems we had early in the season and persistent fog and cool weather, the only grapes we’ve picked have been for cluster samples. With a bit of time on my hands before picking, I thought it would be nice to blog on sampling and how we make the decisions on when to pick.
From my earliest years here at Clos Pepe I have been using internet
technology to reach out to producers and consumers. While it’s
probably pretty common today to email out field samples and post them
on Web sites, back in 1998 it was a pretty new thing. Our Web site was
up back then too, and even though it was a mess, it was a great
resource for winos who liked to see how grapes were grown. I’ve never
thought of anything I do here at Clos Pepe as a trade secret. We grow
the fruit, minimize chemical inputs, treat our workers well, allow the
grapes and the vintage to inform us during harvest and crush, and try
to make wines that are restrained, balanced and food friendly. The
secrets of Clos Pepe lie in the soil, aspect, weather and altitude.
Everything else is transparent: just like Pinot Noir itself.
This morning we got up early (work day early, not harvest early) and
took cluster samples from nine different blocks, seven Pinot Noir, and two
Chardonnay. These results have already been emailed to our ten
producers for 2008: Brewer-Clifton, Diatom, Ojai Vineyard, Ken Brown,
AP Vin, Loring, Siduri, Roessler, Tyler and Clos Pepe Estate. Yes, I
email the results to myself. It’s awfully weird being both a vineyard
manager and a winemaker during harvest. I have dreams where I call my
home number on my cell phone and chew myself out and openly question
the cluster sample results. That’s an inside joke you may not
understand if you don’t make wine.
Cluster samples at Clos Pepe are collected with a fairly exacting protocol, which can be described thusly:
1) Load buckets on an ATV, Gator or Golf Cart. Each bucket is marked
with a Sharpie with the field it is going to be used for. For instance
the bucket might say: Pommard 4 or Dijon 76. At this point, when the
grapes are still a few weeks away, we take samples from larger fields
that are shared by winemakers (Pommard 4), while in a few weeks I might
take separate samples from the Ojai Pommard, the Ken Brown Pommard and
the Brewer Clifton Pommard).
2) Drive down at least two different sections of the same block, often
3+. We choose a random number of vines and clusters – say 17 and 3.
Every 17 vines we stop the cart and retrieve the 3rd cluster on the
right row, and then turn to the left row, count three clusters in and grab
that cluster. Repeat this process until we have around 25 clusters
from throughout the field. Equal amounts of clusters should be
collected from high hillside, mid-hill and in swales.
3) Examine the clusters collected and then crush them with a closed fist in the buckets.
4) Bring the buckets inside (I suggest doing this while the wife’s not home) and begin testing the fruit.
5) Extract the juice from the skins using a pasta drainer.
6) Pour enough of the juice into a piece of small glass lab-ware and test the pH after calibrating the meter for accuracy.
7) Test the Brix by floating a hydrometer and/or putting a drop of
juice on a refractometer, closing it, and checking it under good
light. Calibrating the refractometer with 20-Brix standard is
recommended as well.
8) Record Brix and pH for each sample. We also taste the juice and
make notes to help us reference certain flavors in the final wine. For
instance, when the kiwi disappears from the Chardonnay juice and it
tastes of ripe apples and spice, the grapes are ready (in my mind) to
make wine. Numbers tell a story too, but people don’t drink numbers,
so I like flavor references as well.
9) Rinse the containers between samples with the new juice to be
tested, roll the bit of juice on all surfaces, dump, then refill.
10) Put the results in a safe place and do all the dishes. Clean everything to the point that the wife won’t know that you used the kitchen when she returns. Sticky floors WILL be noticed.

Once the fruit is all collected we beat it like it owes us money.

Squishing the cold Pinot clusters with the fist--the sound, smell and feeling cannot be replicated. Now it’s time to separate the juice from the skins:

Skins stay, juice goes into stainless bowl, then into a measuring cup.

We drip some juice on a refractometer and then check the reading with light. The device measures how light refracts through the juice and gives a reading in °Brix through an eyepiece. Lastly, we check the juice with our brand-spanking new pH meter (after calibrating it).

The refractometer right out of the box.
The samples today, all totaled, produced about 2-3 liters of juice. We have attempted to save all the juice and make a Rose or a Sparkling base, but the stuff always gets neglected during harvest. Our German interns in 2001 managed to make some decent ‘feather wine’ (half fermented) which we drank and got tipsy, but in general we either toss the juice or make popsicles with it. Mmmm…pinotsicles.

Foggy September 15th morning at the Clos (9 am):

And for good measure, a greyhound. Has nothing to do with Pinot Noir, but if you need a dog you should rescue one. They’re super sweet, don’t smell, don’t bark and sleep 20 hours a day. Here is Indy, our Alpha Hound.
