Understanding the Malolactic Coma
January and February are traditionally considered to be the "slow season" at Clos Pegase, because that is when our production team stops to take a minute to catch their breath after the past Harvest.
That doesn't mean that the cellar is a ghost town. The action shifts from the crushpad in September, to the cellar in November through the beginning of the new year, and inevitably the focus lands in the lab in January and February.
While our winemaking team keeps an eye on the vineyards, glancing at the weather report and its lack of rain (the exact opposite of what we did in October of 2011 when we desperately wished for rain to stay away), they are keeping their other eye on the wines that we are getting ready to bottle, not to mention the wines from 2011 that are in barrel (gotta make sure everything is progressing in the right way, you know!)
In order to get a better idea of what type of things go on in the cellar in the "off-season" I headed in to chat with Winemaker, Richard Sowalsky, where he was full of production-world gems.
This time of year, Richard explained, malolactic fermentations are usually wrapping up in the cellar and the team has been keeping close watch to make sure the acid levels are at the desired levels, achieved via this process. What are the desirable levels? So glad you asked.
Before I tell you, I will admit. I'm a rookie at this production stuff (me: grapes get smashed, juice ferments to alcohol, bottle it up and enjoy. Simple. Now we know why science wasn't my strong suit.) So I wanted to know what this malolactic fermentation stuff was all about.
This fermentation, or more accurately, chemical conversion, is the process during which malic acid is converted to lactic acid. For everyone reading this who feared chemistry was a communications major like me, this is like converting the tart taste of apples to the less tart taste associated with sourdough bread. You introduce some "desirable bacteria" into the wine (or use bacteria naturally on the grape skins or in the winery) and they take care of the conversion, a process which naturally de-acidifies the wine. Without ML (as I call it, so I can sound like I know what I'm taking about after my crash course with the production team) many of the wines would taste sharp- great for wines known for crisp acidity like sauvignon blanc; not so great for cabernet sauvignon or merlot.
This conversion happens with almost all wines in our portfolio, with the exception of our Sauvignon Blanc, Vin Gris Rosé and The Portico. (Our SB is known for its crisp acidity so if we allowed malolactic fermentation to take place, that lovely acidity would be gone. Insert sad face here.)
But back to the science of this winemaking stuff. It was at this point in the conversation with Richard that he drew me a couple of molecules on a piece of paper, complete with carbon, hydrogen and oxygen atoms. This was in order to illustrate the ML conversion. I'm going to spare you this part, because it was here was I finally understood what he meant when he referred to this process as the "malolactic coma."
Basically, he went into a whole bunch of science-related topics about bacteria eating carbon chains and stabilizing the wine and I was furiously writing notes down, stopping him every couple of minutes to clarify what he'd just explained.
And I was still confused.
In order to save you from entering into the malolactic coma yourselves (you're welcome for taking one for the team), I'm going to just give your the jest of it, with some history mixed in for good measure:
Wine has three types of acids in it:
- tartaric, which is pretty stable and acceptable in the wine
- malic, which is unstable and can be less desirable because of the tart flavors it imparts (unless you're making sauvignon blanc, or another "crisp" varietal)
- citric, though this is found in very minute amounts.
So, you have these types of acid in the wine and malolactic fermentation is the method that leaves the tartaric acid in tact but more importantly converts the malic acid into lactic acid. During ML, the citric acid also runs the risk of becoming diacetyl. Diacetyl is what causes the super buttery, nutty, oaky flavors in wine that overpower everything else. And if the wrong type of "desirable bacteria" is introduced, diacetyl could be an issue.
Enter the history part of this lesson.
Back in the day, in the Champagne region of France, they were making lovely sparkling wines, but diacetyl (read: buttery, oaky flavors) was overshadowing the delicate bubbles. Some smarty wine scientists then developed a good bacteria that could be used in the ML process that would not leave diacetyl behind as a bi-product and thus, a "desirable bacteria" was born. Then all the winemakers from the Champagne houses rejoiced.
But back to our story.
We choose to mimic the Champagne method of ML because it allows us to emphasize the vineyard fruit and the place from which our grapes come, rather than obscure the quality fruit. Since we age everything in oak barrels, we still have some of the hallmark qualities of varietals (toasty oak, vanilla, etc.) but can better balance those qualities with the fruit characteristics, giving our wines a sense of place while keeping it in balance.
So that, my friends, is the short version of malolactic fermentation, believe it or not.
Trust me, be very glad you didn't get the whole science version. I'm still recovering from the high school chemistry flashbacks induced by those molecule drawings...

Barrels and Forklifts
Thankfully I will not be the one manning the fork lift, mostly because our winery isn't the most forklift friendly place. About ten years ago we finished renovating the two car garage into the present day winery. The 2 arch shaped doors open in the middle (see picture... did you look? Okay back to the story). The forklift barely clears the center of the doors, a huge opportunity to cause some real property damage. Moving the stacked barrels in and out of the winery is an art form, an art form that Jeff has nearly perfected... nearly. (We have only had to repair the damage a few times.) ![]() |

'Exercise Your Taste Buds,' from Peju Province Winery
"I'm checking to see how the wine is maturing, how it's progressing, and to see if any of the individual barrels need attention."
Sixty glasses of wine lined the Production office. Incredulous, I asked her how she could possibly maintain the ability to taste the subtleties in numbers fifty through sixty (or even after #20). She chuckled and said,
"Sixty is nothing! I used to have to taste hundreds of wines in a day at one of the other wineries where I've worked. I'll just take a break after the first thirty, do something else for a couple of hours, and then come back to the last thirty."
At Peju, we age our Napa Valley tier reds for 16-18 months, and our Reserve wines for 26 months, so at this time, Sara is tasting through the 2009 Reserves and 2010 Napa Valley tier reds.
"The 2009 Reserves are dee-licious!" She says with glee. Our Reserves are Cabernet Franc- and Cabernet Sauvignon-predominant Bordeaux blends made exclusively from fruit grown certified organically on our Rutherford Estate. "Though each barrel will impart slightly different flavor characteristics-- and we purchase barrels from several different cooperages for this reason-- all the 2009 reserve wines themselves are full of rich, ripe, dark fruit flavors. 2009 was the last great year before the trickier two to follow, but I've been pleasantly surprised at the way the 2010's are tasting today, as well."

No More Monkeying Around in the Cellar for Me at Peju Province Winery
Today, I write to you from my brightly lit desk in the very tame upstairs offices. Actually, ironically, I just heard a cacophony of high-pitched hollers from the other end of the offices. Sounds like a big sale came in, woo-hoo! The holidays are an exciting time for Patti, Jess & Christina who take care of phone sales. Anyway, it is the first Friday in two months that I've had to iron before clothing myself presentably, and that I've come to work to spend the day wielding the almighty mouse and keyboard. Slightly different strengths required than those for wielding the heavy hoses and 20-gallon buckets of juice in the cellar. I am in the office today because finally the seasonal work requiring so many extra hands has come to an end. There is still much going on for the full time cellar workers, but they've got that under control. We drained our very last tank yesterday to press and barrel down today- Cabernet Sauvignon from one of the later-ripening blocks on our Persephone Vineyard. Almost all of the leaves have fallen off the vines, which are now dormant and will remain so until spring when the weather warms, rousing the vines out of their winter stillness to begin again to do what they are meant to- to photosynthesize, to pull nutrients out of the ground to create leaves and eventually to flower and to bear fruit.
'Dormancy', as defined by Wikipedia, is "a period in an organism's life cycle when growth, development, and (in animals) physical activity are temporarily stopped. This minimizes metabolic activity and therefore helps an organism to conserve energy." (http://en.wikipedia.org/wiki/Dormancy) My organism can relate to that.
| Dormant Vines on Peju's Rutherford Estate |
Next week Winemaker Sara, Assistant Winemaker Joe, and Production Planner Sheri will begin tasting through the 2011 whites to see how the now two-and-a-half-month-old wine is tasting, and to start thinking about how they'll want to blend it in a month or two. Blending involves systematic tasting through barrel-aged versus tank-aged lots, lots in French versus American and new versus neutral oak, and then blending varietals with any combination of these variations. Love how winemaking involves doing science with your taste buds.
Most of the work that's going on in the cellar these days is to take care of the older vintages of reds that were laying low in their barrels while Harvest's new crop, like a needy newborn sibling, took all of the attention. Mostly, it's the topping I mentioned in a a recent blog post that the crew is busy with now. On a monthly rotation, the crew will bring all of the hundreds of barrels in our Estate cellar out to the crush pad to make sure the headspace in each barrel is at a minimum, lest the wine breathe too much oxygen and lose its youthful vigor.

And as the vineyard rests for winter, the sales team springs to action for the most wonderful time of year for us humans! It is certainly true that some of the best gifts in life are free. But wine is always a great gift too. Cheers!

GI Status Approval in Thailand
The NVV worked directly with Thailand's Department of Intellectual Property on the registration which reads, "The combination of Napa Valley's unique geography, climate, geology, and the winemaking traditions as well as the human skills of the Napa Valley vintners give Napa Valley wine its distinctive taste and unique characters."
"This is a terrific accomplishment for our trade group in protecting our appellation's name from fraudulent use in yet another high-profile, emerging wine market," said NVV Executive Director Linda Reiff. "We have been able to achieve this and other GI recognitions by working directly with these government agencies, such as our successes in the EU and India, which is important to building our export channels for Napa Valley wines."
"It's necessary to know that consumers of Napa Valley wine in Thailand will be able to trust that if it reads 'Napa Valley' on the label, that the wine in the bottle is indeed from California's Napa Valley," said Pat Stotesbery of Ladera Vineyards who chairs the Napa Name Protection Committee for the association.

With All Our Grapes Safely in Tank and Barrel, We Begin Our Descent Into Winter Calm at Peju Province Winery...
The Napa Valley Designated Official Wine Region of the 34th America's Cup
The Napa Valley has been named the official wine region of the 34th America's Cup. In partnership with The Napa Valley Vintners (NVV) and The Napa Valley Destination Council (NVDC), America's Cup events in the United States through 2013 will exclusively feature Napa Valley wines, while the Napa Valley will be the only wine region featured as a getaway destination for attendees of the San Francisco-based America's Cup events.
"The America's Cup is a fantastic way to showcase the wines of Napa Valley. This high-profile, world-renowned sporting event's stature perfectly aligns with the high quality and world renown of Napa Valley, America's premier wine region. We are delighted to bring our wines to the table in celebration of this great partnership," said Napa Valley Vintners Executive Director Linda Reiff.
"Many of the America's Cup enthusiasts love the same things that the Napa Valley is known for--great wine, food, arts and wellness activities. We are very excited to have the opportunity to invite them to experience our beautiful region while they are in the Bay Area, and we look forward to sharing the best we have to offer," said Clay Gregory, NVDC CEO and President.
The Napa Valley is home to the founders of America's fine wine industry--legendary entrepreneurs who showed the world that the art of winemaking had crossed continents--and the region is prized for its natural beauty, 14-Michelin Star culinary scene, world-class hotel accommodations, robust arts community, and one-of-a-kind wellness experiences including the region's famed spas, mud baths and healing geo-thermal hot springs.

Fourth and Final Harvest Update
Harvesting started in a panic as many winemakers, this one included, realized the scope of the challenge that the mold pressure presented; a block with trace amounts of botrytis could become completely enveloped in twenty four hours. The thin skin, tight cluster varieties were the first to succumb to the fungus. Petit Sirah and Petit Verdot were particularly hard hit and were triage priority when making pick calls. The Round Pond Estate however, has the fortunate ability to harvest any block any day that’s needed or desired—a resource that proved particularly crucial this year. Throwing courtesy and convention aside, I called many picks the same day I walked out into the fields and realized that another block absolutely must come in.
Following the rains, we had a string of warm, windless days that were perfect for fungus growth. On the valley floor, the sun heated the saturated soil, which raised the relative humidity in the fields. Those vines trellised in curtain forming fashion trapped the evaporating water and created a sauna-like environment, which further exasperated the tendency for mold to spread. When temperatures fell at night, the surface of the grapes cooled and the trapped moisture below the canopy condensed on the fruit so that by daybreak, the clusters were dripping with dew. Vines trellised in a vertical fashion did not suffer the “sauna effect” and fared better against the mold. Also of note, the more gravely sections of vineyard blocks dried out more quickly, and were subsequently less susceptible to mold pressure.
Winemaking, like any science, is an exercise in observation. Walking the vineyards, it was critical to understand why some blocks were more affected by botrytis than others in order to make decisions on optimizing fruit quality and harvesting efficiency. Having learned from our early picks, it was apparent that the benefit of a few extra days of ripening was negated by the sensory influence the mold had on the wines. As such, I tended to pick at the first signs of mold development, which I believe preserved the fruit character in the grapes and has given us the foundation for producing wonderfully elegant and seductively aromatic wines.
November 1st marked the last day of harvest on the Estate and in that twenty-two day period, the production crew broke records three consecutive times for number of tons processed in a day, and the amount of fruit received at the winery in a week’s span. These statistics do not come as a surprise to me; all vintages at the Estate are fast and furious but late ones, like this year, especially so. Harvest at Round Pond is most certainly a sprint and not a marathon.
Thanks to all of the staff in other departments who came to lend a hand on the sorting line, delivered food and libations, or simply gave a kind word of encouragement. Those sentiments never go unnoticed and are certainly appreciated. I look forward to sharing our collective efforts with everyone in the years to come, and feel the climatic challenges of this vintage will prove to be a historic bellwether for the exceptional consistency of quality achievable on this Estate.
Humbly,
Brian Brown

Napa Valley Wraps-up Harvest 2011
Challenging year in the vineyard reaps rewards in the cellar
"Although it may be stretching to compare our harvest with one of the greatest ever games in the history of baseball...but like the 2011 World Series, we had our ups and downs, and finally pulled it out. This was one of our most exciting harvests ever!" said Cain Vineyards' Winemaker and General Manager Chris Howell. And once again the excitement of the finale of the American baseball season seems to parallel that of the vintage at harvest from America's premier winegrowing region, the legendary Napa Valley. Today the Napa Valley Vintners (NVV) non-profit trade association of more than 420 wineries representing 98% of the appellation's wine production offers its annual report on harvest.
"2011 was a challenging and as well as what I am calling 'an educational vintage,' the third in a row," said Oakville Ranch Winery General Manager Paula Kornell who was born and raised in the Napa Valley wine industry. "What we found this vintage were flavors that developed at lower brix, giving us an opportunity to make truly elegant wines at lower alcohol levels."
"Harvest 2011--from tears to glory!" is how renowned vintner Tim Mondavi, owner of Continuum capsulized the year and winemakers appellation-wide are in agreement.
What began with a wet winter and spring continued with rainfall into mid-June that delayed bloom and disrupted fruit set resulting in shatter in parts of the region set the stage for a long, cooler-than-average growing season with a later-than-average harvest beset with autumn rain storms. The precipitation measuring season ending on June 30 found the region more than a third above normal in rainfall. While this is good news for water resources, the cloud cover and cool temperatures delayed vine development by several weeks at the onset of the growing season.
This timetable continued through the somewhat cool summer season where harvest for the first varieties for sparkling wines found the latest harvest start in anyone's memory, beginning August 29. Few high heat events occurred at any point this year, but growers managed more open vine canopies to ensure sunlight, warmth and good air circulation around the grape clusters. The shatter resulting from the rain events in June was variable by vineyard location hitting some locations harder with projected crop diminished by more than 30% while leaving other sites nearly untouched with near-normal crop.
New Media Resources Tell Story of Year in Real Time
New this year, wine lovers around the world were able to follow the Napa Valley harvest like never before. Twitter was a-buzz at #NVHarvest with thousands of tweets from the vineyards and cellars. Read the ongoing Twitter feed at the www.napavintners.com/harvest.
Napa Valley filmmaker Bret Lyman chronicled the vintage in a series of harvest videos beginning in August with the start of harvest for sparkling wines to the white varieties, Merlot and then Cabernet Sauvignon. Check out today's release of the final chapter of the harvest videos below.
The region's winemakers and vineyard managers participated in a week-long "Harvest Live" streaming video the week of October 17 with six days of morning and afternoon live chat painting the picture in clear detail of what was happening in the vineyard and in the winery in real time. Check out U-Stream to watch the archived programs hosted by Christophe Smith of Titus Vineyards along with his esteemed guests.
And, more than ever before the vintners themselves blogged all season on their experiences in written, photo and video posts on the NVV's official blog "Unfiltered."

2011 Harvest Complete at Vineyard 7 & 8!
Greetings from the top of Spring Mountain!
As we close yet another harvest from Vineyard 7 & 8, I look back on what was a true test of patience. A season filled with extra efforts in the vineyards working on crop and canpy management, a couple early October rain storms, but finished up with a period of beautiful weather.
Over the last couple of weeks the sun returned, and the dry northwest winds returned, allowing us the ability to harvest what looks to be another very successful vintage.
Cabernet from our Estate vineyards and the fruit we harvest from select neighboring vineyards on Spring Mountain came in with more moderate sugar levels, beautiful acids and wonderfully refined tannins.
Fermentation is just beginning to take shape in the tank room, and hats change from the management of the fruit in the vineyards to pumpovers and punchdowns, monitoring of tanks and prepping barrels for later in the month when the wines will go to rest.
Congrats to all fellow vintners for yet another wonderful harvest in the Napa Valley!
Cheers,

Yeast Whisperer of Newton Vineyard
The first days of the Newton Chardonnay harvest are stressful.
We pick it, we press it, we choose the best French barrels and… nothing happens. For days, the juice is quiet, viscous, cloyingly sweet.
Nothing… No matter how much I stare inside the barrels or glue my ear to the bung holes until the side of my face shows a ring of toasted oak smoke.
It’s only when I start getting that recurring dream of hot tubs filled with bubbling grape juice, around the 6th or 7th day, that our tricky indigenous yeasts deign offer some hope. Suddenly, the whole cellar is filled with the gurgling sound of the starting fermentation and I breathe a sigh of relief.
That makes Julian laugh.
Julian Cendejas (pictured at right) has worked at Newton since 1989. Over his more than 20 harvests, he’s learned to be patient and that the fermentation will start. Some years it’s fast -just a couple of days- some years it takes up to 10 or 12 days. Once a lot of Chardonnay is fermenting, the whole cellar follows.
Julian always knows when this will happen: I have a theory that he’s somehow communicating with the yeasts that come from our vineyard. He’ll say “Tomorrow, this lot will start”. I’ll look in the barrel he is showing me, shaking my head: “Naaah, there is not even any froth.” The next day, he’ll be right.
Now, all the 2011 Chardonnay is fermenting, some lots well on their way to dryness. It was a cool growing season and even if the sugars remained lower than in the past years, the flavors are exotic and complex. There are apricot and grilled pineapple notes but no hint of the quince paste that characterizes over-ripe vintages. The musqué lots are delicately floral without being too wisteria or lilac-like.
This should be a vintage for aging. But shhhh… Don’t tell our yeasts: they are not done with their job until Julian says so!
Cheers!

Crush is 76% Complete, and It's a Happy Halloween at Peju Province Winery!
As of today, we've brought in 76% of our total crop. Sara aims to harvest all remaining fruit by this Friday. It's all fermenting, pressing & barreling down from there!
Sheri, our Production Planner, gave me some "fun facts" today. (Visit the 'Meet the Team' page on our blog for photos and titles of everyone on the Production team.)
These are the dates on which we had brought in the last of our fruit over the past four years:
October 11, 2007
October 28, 2008
October 25, 2009
November 1, 2010
And if all goes to plan, it will be November 4 in 2011. Not bad considering we started harvest 4 weeks later this year than in 2009. And by 'not bad' I mean 'this was one logistical nightmare' with the same number of tanks as in years past and around the same amount of fruit coming in, only this year in a much more condensed period of time. Sara and Joe had to use acute foresight to plan their tank assignments and rotations, making sure to align when to bring the fruit in (dependent on nature) with how much fruit had been predicted to come in (a tough (inexact) science) with what kind of tank space would be available at that time. Who knew such a big part of wine-making could be about the logistics of coordinating ripening with fermentations with tank space.
At the Family Meal today, Sara gave us a harvest-time update:
