At Least 28 Napa Wineries With Major Damage or Destroyed. Here's a list.
Fires in THE Valley!
Here's a partial list of major damage just in Napa Valley proper.
$2 Billion Dollars in Damage
What can/should be done?
Another year of raging fires across California in 2020, and there is still at least a month to go in our annual, "Fire Season". I've written about the history and challenges and arguments over the causes and solutions to the problem from all points of view, but one fact is undeniable: California MUST perform a massive "Reduction in Hazardous Fuel" in their forests. There are 50+ years of dead trees and underbush on much of the public lands. (I know, I know, everyone can be mad at me from all sides, but live and/or be a property owner in California in the path of these fires and you will come to the same conclusion.) Good news is that California and the Federal Government have agreed to undertake a massive collective effort to start doing just that. This will be a multi-billion dollar, 5+ year effort, but it will thankfully start happening. Too many lives, homes and property have been lost.
Napa Valley is the best known wine region in the United States and generates an estimated $40+ billion annually to the national economy. It is some of the most expensive vineyard land on the planet. There were multiple fires in Napa and Sonoma in July and August and then the Glass Fire started September 27th and burned over 68,000 acres. 100's of home and businesses were destroyed. There were also at least 36 wineries heavily damaged or totally destroyed. (See a partial list below)
There is some good news. There are still over 500 Napa Valley Wineries fully intact. They are still challenged greatly with COVID-19 business restrictions, but do not have to start from scratch. The larger concern for 2020 is that about 20% of Napa Valley wineries have decided to not use all or a portion of this year's grape harvest due to smoke taint. (Bitter taste in finished wine because of ash and soot laying on the grapes on the vines and infusing phenols and other chemicals into the grape skins.) A large number of other Napa Valley wineries will wait until about Febuary to assess the smoke taint damage in their 2020 post-fermentation wines. This could be a large problem for 2023 when this year's red wines would normally be released.
The property damage in Napa Valley is estimated to be at least $350 million. At least $60 million of wine inventories were destroyed. About 1/3 of this year's grape harvest in Napa Valley is expected to be ultimately found unusable for wine production which will cost about $300 million, and the ultimate cost of lost wine sales will approach $1 billion over time.
Support your faviorite winery!
And remember: Americans Never Give Up!
Most Importantly: Never forget our First Repsonders! They run toward the danger, so that we can run to safety.
Thanks so much, Jim Langman
Record California Fires!
This is a republication from the last record year of wildfires in California, 2018. 2020 has surpassed the 2 million+ acres of burned land in 2018 with more than 4 million acres destroyed this year! This content is more relevant than ever. (Jim Langman)
The satellite image above was created by the National Weather Service, (NWS), the same week we were in wine country last month. It shows the upper atmosphere concentration of smoke particles generated by the large fires in California and several other western states. There is visible smoke from coast-to-coast and is evident in almost every contiguous state in the U.S.
You can see a dark orange finger of color cutting right down the center of the northern border of California. Two of the seven largest fires ever recorded in California that are burning this year in northern California are causing most of this smoke concentration. The largest fire ever recorded in California, The Mendocino Complex Fire, has been burning for months and is still not fully contained, has already burned 470,000+ acres. (Source: Cal-Fire) This fire is burning about 40 miles north of Napa Valley and Sonoma County. About 100 mile north of the Mendocino Complex, The Carr fire burnt 230,000+ acres before it was contained last month. (Source: Cal-Fire) We are blessed that our vineyard is at 2,400 feet elevation, in the Sierra Foothills which is right in the middle of the large green streak on the eastern border of the center of the state in the image above.
What does this all mean?
The rest of his article will have 2 parts: How does this much smoke effect a vintage’s grapes and wine and some hard data and facts about California fires. The first part, I hope, you will find interesting and informative. Everyone will probably be mad at me about the second part. That is not my intention, but I do accept the responsibility to present the facts and a viable effort to partially mitigate the yearly fire battle that happens every summer in California.
Exposure to heavy smoke for an extended period of time can allow the chemicals in the particulate matter from the smoke to be absorbed into the skin of the grapes. In 2008 there were some large fires close to Napa Valley and smoke taint did effect the thick-skinned, slow-to-ripen Cabernet Sauvignon grapes, which did, in turn, effect the quality of wines in multiple wineries. This could be a challenge this year in Sonoma county and again in Napa Valley.
Fining and Filtering are the processes that wine makers use to eliminate most smoke taint from their wines. These aggressive processes, to varying degrees, will also usually dilute the wines complexity and taste. The wines are enjoyable, but not as robust as usual.
Fining is the technique where the wine maker will add an adsorbent to wine in tanks or barrels. These inert compounds literally attract the volatile phenols and creosol chemicals out of the wine and into their chemical structure, (not exactly the same, but think of a sponge absorbing water off kitchen counter), and then the adsorbents are then removed from the wine. Using activated carbon or synthetic mineral fining compounds has shown to remove between 50 and 70% of the smoke taint chemicals from the wine.
Very fine micro filters can also be used after the fining process. These can remove very fine chemical particles, but the trade off is lower viscosity and concentration of wine particles. Science and the wine makers experience and skill in these decisions is one of the big ways that prove an excellent wine makers prowess.
Most wineries in the Sierra Foothills will thankfully not have smoke taint this year. But this years massive fires have had a different effect on our area by effecting the weather. The smoke in the upper atmosphere has filtered the intense sun that normally results in daytime August temperatures in the mid 90’s and have resulted in most of our August afternoons peaking out in the high 80’s.These cooler temperatures have allowed the start of “veraisin”, the change of color of the grapes from green to dark blue/purple, to happen about 3 weeks earlier than normal. Veraisin signals the onset of the final stage of grape maturation and the beginning of “ripening” of the crop. The grapes will concentrate complex pigments in their skin, increase sugar in the juice and and be ready for harvest about 6 weeks later. (Veraisin is also the favorite time of the year for birds to visit the vineyards and feast on very expensive grape clusters!) Last year we were harvesting into the first week of October. This year we will most likely be finished with harvest by the 3rd week of September. This is not a bad thing. Every vintage of wine has its unique characteristics!
Hard data about California fires
I am a Pharmacist by education and licensure and for decades, have followed the “Scientific Method” and “Evidence Based Medicine”, to construct and/or administer, “Patient Care Protocols”, to treat patients with the treatment regimen that has the highest likelihood of success for that specific patient and their specific needs. Clinicians, of all types, can not use emotional decisions nor superficial knowledge to responsibly and safely take care of their patients. This section is not meant to be published in a peer reviewed journal. I am simply presenting hard data on some macro issues and humbly submitting a partial mitigation proposal. I will give example of both sides of the argument wherever I can.
“There are more and more horrible fires, every year in California and the planet and this is direct evidence of, and directly caused by, Global Warming!”
Fact- These are horrible fires. Absolutely no question about that. So far this this year, in California, there has been at least 5,600 fires, that have consumed 900,000+ acres, burned 1,000+ homes and killed at least 12 people, including 4 firefighters. (Source: Cal-Fire)
“…more and more fires every year…”
Fact- The state of California since the year 2000 has averaged 8,100 fires/year, with an annual average acreage burned of 640,000 acres. These number fluctuate year to year with no evident multiyear-trend up or down. (Source: Cal-Fire)
Fact- The entire U.S. had 3,900 fewer fires last year than the 10 year average. The total number fires and burned acreage fluctuates every year and shows no multiyear trend over the last 20 years. (Source: NIFC)
Fact- On a global basis, the total Global Burn Area for the decade of 1900-1910 was 43% higher than the decade of 2000-2010. This downward trend has been happening for 100 years. (There is a lot more to unravel here, I get it! ) (Source: Bio Science Journal of Geophysical Research)
“…direct evidence of Global Warming…”
First side- “Thousands of scientists agree that there is global warming and the earth is 1.8 degrees Fahrenheit higher than it was 70 years ago.”
Second side- “You are looking only at a relatively short timeframe of temperature measurement that is only part of a much larger and longer natural cycle that the earth constantly goes through.”
Fact- The last 15 years on California has seen some higher temperatures and dryer winters on average. The snow pack on the mountains has not been as deep and this reduces the spring/summer runoff much earlier in the year.
Fact- This is too short of a timeframe to make an absolute judgment about Global Warming
“…these fires are caused by Global Warming…”
Fact- The first 17 major fires in California this year were caused by humans, not lightening strikes. (Also, these forests do not spontaneously combust!) Human causes include downed power lines, machinery, careless smoking and/or campfires and arson. Arson has averaged about 350/year for the last 20 years in California. (Source: CalFire)
Fact- In California from 1910-2017, 95% of all fires were caused by Humans. 5% were caused by lightening strikes, mainly in the rural northeast corner of the state. (Source: U.S. Geological Survey Western Ecological Research Center)
“If the number of fires and the acres burned only fluctuate year over year, and are not on an upward trend, why don’t we just leave mother nature alone and do nothing.”
Fact- The fires last year in California, killed at 27 people, destroyed 4,800 homes, cost $773 million in fire fighting expenses and $1.8 billion in damages. (Source: Cal-Fire)
Fact- The number of residents in California in 1980 was about 24 million. Today, it is about 40 million. (Source: U.S. Census)
Fact- From 1940-2010 the number of homes potentially in the path of wildfires has risen 1,000+ %. (Source: National Hazards May 2018)
Fact- 1/3 of the population, about 13 million people, in California now live in the “Wild Land/Urban Interface”. Summer in California is the worst place in the world for fire climate. (Source: J. Kelly UCLA)
Fact- California is the driest state in the U.S. during the summer months. (Source: NWS)
What could we/should we do?
Doing nothing is not the answer. There are at 13 million people in California who live in potential wild fire danger. I am not going to argue about how we got here, but we are here. Can we introduce some responsible forest management back into these public lands? Many people agree that Hazardous Fuel reduction is the most effective way of reducing the frequency and today, the intensity of these major fires. How we do this is where the disagreements start. Dead tree and underbrush removal, controlled burns, reopening some of the forests to responsible commercial logging are all hotly debated.
First side- “The forests have burned and renewed for as long as earth has existed.”
Second side- “There are millions of people at risk!”
First side- “You produce more CO2 into the environment when you artificially reduce hazardous fuel and/or back burn and/or allow logging than the fires produce, because only about 10% of the available carbon is released in a forest fire where only dead trees and underbrush are burned. The fire does not go past the bark of healthy trees.”
Fact- Commercial logging had a 150 year history of “cutting and running” in many parts of our public forests. There were many destructive environmental effects of these unregulated and unenforced times. Modern regulations, equipment and processes have proven to be a sustainable environmental and business model on the private lands where most logging occurs today. Is this absolutely perfect? Absolutely not. But we have come a long way,
Fact- Most commercial logging on public lands in California was stopped 40+ years ago.
Fact- A healthy forest has about 40-60 trees per acre. Many of the fires now burning in California are burning on public land that has not seen Hazardous Fuel reduction in 40 years. These lands now have 100-200 tress per acre, as well as an enormous amount of dead trees and underbrush. Combine this with everything else we have covered and you can see why the intensity of these fires is staggering. Many parts of these large fires are now burning an estimated 50-75% of available carbon in these raw forests. The fire is burning through the bark and killing many large trees. This type of destruction can mean that a forest will take 75-100 years to return to its full health. (Source: U.S. Forestry Service) Doing nothing is absolutely incorrect.
Doing the same thing we did 40 years ago is absolutely incorrect. Absolutes on either side of the points of view on this problem are not based on facts. We must strike a balance that is good for the humans in danger, good for the environment and good for the economy.
Okay, now that you are all mad at me, please remember that I am a Pharmacist and grape grower. I absolutely know that I have not covered everything, but I do know that we must formulate a responsible plan for Hazardous Fuel Reduction in our forests.
Our vineyard team picked 81 tons of grapes! Now what happens?
Our Winemaking Team Gets Really Busy!
What a long and stunning growing season!
Harvest lasted until Tuesday, October 13th!
For most of us, when we hear the words, “wine grapes”, and, “crush”, visions of of large, round, slotted wooden vats with big metal screw-driven plungers come to mind. Or, more enjoyably, memories of the wonderful 1960’s Lucille Ball Show where Lucy has donned a traditional Italian peasant dress hiked up to her knees happily stomping grapes with her feet, in a huge round vat the size of a small swimming pool! You can actually get the juice out of your grapes with either of these methods, but there is a better, more gentle process to maximize the juice extracted while maximizing the quality of the wine. There are a couple steps to the better process we refer to as “Pressing”.
What’s the difference, and why is this important?
Crushing grapes the old way does get the juice out of the grapes but also pulverizes the stems, skins and seeds. Why is this not ideal? The next time you buy a bunch of grapes pull a single grape, with the stem still attached, off the bunch. Gently bite into the stem and you will get a “green” bitter taste. Now peel off some of the skin and gently bite into this. You will get a slightly sour taste that can be described as tannic. Now, very gently bite into the seed. You will get another bitter but woody taste. Compare these to the sweet juice and pulp taste of the rest of the interior of the grape. When wine grapes are pulverized the old way, these bitter tastes can carry through to the final quality of the wines. Tannins are one of the essential final components in a fine wine, but they must be at the proper level. (In our next edition we are going to describe the fermentation process, which involves the skins actually soaking in this freshly produced grape juice.)
- “First Press”, (cracking the skins, not pulverizing)
- Collect the First Press Juice in the fermentation tank
- Second Press, (bladder press the pulp)
- Collect the Second Press Juice and pulp and cracked skins in the fermentation tank
- Start the fermentation process
This sophisticated method of “Pressing” is more complicated and expensive vs. crushing, but the quality of our wines that it produces is absolutely worth the effort!
When you look at the picture below, you will see a large, square, white bin that holds about 1,000 lbs of grapes, being slowly tipped over and pouring the grapes into a large steel machine. You can see the winemaking crew pulling out any leaves or spoiled bunches and then let the grapes roll under a safety shield where they drop into the de-stemmer that then feeds the grapes into the First Press part of the machine.
Stems coming out the side of the machine. These are biodegradable.
Below shows the juice coming out of the bottom of the De-Stemmer/First Press machine. The juice goes into the fermentation tank through the hose on the bottom. This First Press gets about 80% of the juice out of the grapes.
The slot on the bottom of the machine shows the juice dropping and flowing into the striped pipe on the bottom.
Now all of the good stuff that’s left in the De-Stemmer/First Press machine goes into the Horizontal Bladder Press. This is a large stainless steel machine loaded with all of the pulp from the first press. The machine has a large plastic membrane on the inside that separates the inside of the drum into two spaces. One side is filled with water. The other side is where the pulp is added. The machine then spins the whole drum, and the centrifugal force pushes the water side of the bladder against the pulp and voile’! The rest of the juice gets extracted without pulverizing the skins and seeds then getting pumped into the fermentation tank.
The next step in turning great grapes into great wine is, “Fermentation”.
We'll cover that in a future edition!
Cheers! Sue & Jim Langman
