Bob Lindquist and Jason

As regular readers of Wine Nation Underdog know, my husband and I have been preparing to make wine, so we’ve been eagerly awaiting the day our grapes are harvested.  Back near the end of September we toured the Sawyer Lindquist Vineyard.   We tasted Syrah grapes from all over the vineyard and tried to decide which blocks’ fruit we wanted in our order.  Since this was our first time actually choosing and purchasing grapes, we were thrilled to have renowned winemaker Bob Lindquist there to offer his guidance.

As we walked through the vineyard, we tasted Syrah clones including Estrella, 174, 383, 877 and UCD-01 from various blocks.  It was amazing to me that there were such distinct taste differences between the clones.  The Estrella had hints of coffee and black pepper.  The 174 had notes of black plum and dark berries.  After sampling many grapes, we decided that our order would be made up of three clones:  Estrella, 174 and UCD-01.    No one is sure when the grapes will be ready to pick, so I try (and fail) at being patient.  Weeks pass …

I’ve noticed that all plans during harvest seem to change dramatically.  We had everything all lined up for our Côte Rôtie inspired red wine.  We thought that the Syrah fruit was going to be picked the week before, but it wasn’t quite ripe enough, so we postponed for another week.   We’d also made arrangements to pick up Viognier skins and stems from Peter Work of Ampelos (thank you Peter) last week.  Since we changed the pick date, the plan had to change again.  Thankfully, Peter had more Viognier from Wezlau (formerly named Vigna Cesarina – located between Seasmoke and Mount Carmel vineyards) coming in the following Monday which coincided with our pick date.

grape pickers Picking day finally arrives and the alarm goes off at 5:00am.  It is still dark, and Jason and I are groggy but we grab a quick breakfast and head over to the Lompoc Wine Ghetto to borrow the Jalama Wines truck (thank you Mark Cargasacchi!) so that we can go pick up our freshly picked Syrah grapes at Sawyer Lindquist Vineyard.   The sun comes up as we drive towards San Luis Obispo.   We arrive at 7am and find out from  Bob Lindquist that the pickers are working on our order (which included three different clones from three different blocks:  Estrella from block 4, UCD-01 from block 3 and 174 from block 1 ), so the bins aren’t quite ready yet.   High quality wine grapes are harvested by hand.  When the grapes are picked they are placed into bins that are lugged by hand getting heavier and heavier with each added cluster.  Pickers work in the early morning hours when it is cold and damp and often fend off yellowjackets and bees.  They work incredibly hard!   Many thanks to the crew who picked our fruit!

grapes getting weighed

weighing the grapes

Once our order is completely picked, it gets weighed and then loaded by forklift onto the truck.  Though we only planned to get a half a ton (1000 pounds) we ended up with 1401 pounds.    Even now, after the grapes are picked, the plan keeps changing!  We have one barrel set aside for the Syrah, so we’ll need to figure out what to do with the juice from the additional 401 pounds of Syrah.  The plan keeps changing!  We arrive at Jalama Wines and Mark unloads the grapes by forklift.  We have plans to have the grapes destemmed at 10:00am…but the schedule for the destemmer changes (of course) so we end up waiting a few hours so we hang around Jalama Wines and try to make ourselves useful.  Once we get the fruit destemmed (thank you Doug!) we take a sample bottle of the juice to take to the lab for analysis.  We also check the brix using a hydrometer.  Next we make a few additions:  SO2 to prevent spoilage, Opti-Red (an inactivated dry yeast that improves color and adds body and mouthfeel) and Lafase He Grand Cru (an enzyme preparation that increases the extraction of stable phenolic compounds).   We are hoping that the grapes and the winery have enough wild yeast in order to have a native fermentation take place.  If that doesn’t happen, we’ll go ahead and inoculate the grape must with yeast..but I’m really hoping we don’t have to do that.

Mixing the additions into the destemmed fruit

Since we ended up with extra Syrah fruit, we’ve decided to drain off some of the juice in order to make a rosé.   I pop over to Home Depot to buy some plastic carboys to hold the juice for a short time until we figure out a long term plan for the rosé .   After we drain some of the juice (this process is called saignée in France) into the carboys we jump back into the truck and head over to Ampelos to pick up Viognier skins and stems that we’re going to add to our destemmed Syrah for the cold soak.   We arrive and Peter and his guys are working but the Viognier isn’t ready yet.  So, we head back over to Jalama, pick up our wine sample and head to Santa Maria to drop it off at Vinquery.  We also take the bins with us and drop these off at Qupé / Au Bon Climat winery in Santa Maria.  We also stop at a welding supply store to pick up dry ice which we’ll add to the destemmed fruit in order to bring down the temperature and prolong the cold soak which we hope will yield deeper color and more aromatics.

Next, we head back over to Ampelos where they are done pressing the Viognier, so we pick up the skins and stems.  Once we reach Jalama (who knew winemaking involved so much driving?) we add the skins and stems to our bin of destemmed Syrah.  Jason adds 100 pounds of dry ice to the grapes which makes the whole bin look like some strange witch’s brew.  We’ll be back tomorrow to do punchdowns in the morning, afternoon and the evening.  Even though fermentation hasn’t even started, I am already anxious to taste the finishes wine…which won’t be for at least two years…perhaps I will learn patience from winemaking?

The first Pinot Noir harvested from the student vineyard.  Many thanks to the viticultural students!

The first Pinot Noir harvested from the student vineyard. Many thanks to the viticultural students!

It is very strange to be attending college again after graduating so many years ago.   Recently, I showed up for my first day of wine making class at Allan Hancock College (go Bulldogs) and expected to sit in a lecture hall taking notes for 4.5 hours.  Boy, was I wrong!  Our professor, Norm Yost (winemaker of Flying Goat cellars) spoke for about an hour, assigned some homework and then let us know that we have 600 pounds of Pinot Noir to work with – TODAY!   He said the grapes won’t wait, so we just have to sink or swill, err swim. ;)   Our mission in class is to make a sparkling wine from Pinot Noir.  This is traditionally called a blanc de noirs, literally “white of blacks”, meaning a white wine that is made from black grapes.

After the brief lecture, we headed down to the tiny campus winery  (why, oh why didn’t my alma mater have a campus winery?) where 600 pounds of freshly picked Pinot Noir grapes were waiting in bins.  This is the first Pinot Noir harvested from the Allan Hancock student vineyard.  (Many thanks to all the viticulture students who made this happen!)  First, we put up canopies to keep the sun off of us (and the grapes) and then moved all the equipment we’d need: bladder basket press, pump, fermentation tank, various clamps, gaskets, hoses and buckets.   We took everything apart and thoroughly washed it.  Then we put it all back together and attached the pump’s hose to the fermentation tank.

Basket press

The bladder basket press gently presses the juice from the whole clusters.

Next we filled the press with whole clusters of grapes and pressed off the juice.    Then we pumped the juice into the fermentation tank.   Then we filled the press with grapes again and repeated the process (we did this quite a few times until all the grapes were pressed).   We took a sample of the juice and tested its brix with a hydrometer.  Our reading was 18.2 brix.   After all the grapes were pressed, it was time to inoculate the juice with yeast and get fermentation started.

winemaking math

Calculating the amount of yeast needed for fermentation.

This involved more math than I’ve done in many years.  Essentially we needed to make an educated guess of how much wine was in the fermentation tank (why aren’t tanks conveniently marked like measuring cups?).  This involved calculating the volume of a cylinder…something I am certain I learned in high school, though haven’t thought about it quite some time.    Here is how:
1. Measure the height of the cylinder (up to where the juice is)
2. Measure the radius of the cylinder (across the top of the tank at the widest point)
3. Multiply the radius by pi (3.14159)
4. Multiply the radius by itself
5. Multiply #3 by #4
In our case we wound up with 42.1 gallons.  In order to figure out how much yeast to use, we needed to translate our gallons to hectoliters.   To do this, we multiplied our gallons times 3.785.   42.1 gallons x 3.785 = 1.59 hectoliters.    Next we multiplied the hectoliters by the number of grams of yeast required in order to calculate the amount of yeast required for inoculation.  1.59 hectoliters x 25 grams = 40 grams of yeast.   We combined the yeast with 400 milliliters of 105F water in a measuring cup and let the yeast begin their work.  After a few minutes we combined about a 1/2 C of juice to the mixture.  After stirring the mixture up, we added to to the tank and stirred with a big, plastic oar-like implement.

We then attached the lid of the fermentation tank.  Lastly, we created a schedule so that once daily a student would go check on the fermentation, take the brix and temperature reading with the hydrometer and log the results.  Jason and I are going later on in the week, so the initial fermentation will be nearly halfway done (it should take about 2 weeks to complete).   If all goes as planned, the fermentation will be well steadily progressing.   Even though the soon-to-be-wine is still in the fermentation tank, I am already looking forward to popping the cork.  My favorite sparkling wine is Schramberg Blanc de Noirs; hopefully someday I can craft a sparkling reminiscent of this.   My fingers are crossed!
