In Napa Valley this time of year, you’re likely to see vineyard crews scattered amongst the vines. “What are they doing,” you ask? They are Shoot Thinning and Leaf Pulling.
Shoot thinning and leaf pulling are part of overall vineyard canopy management, as seen here in Sauvignon Blanc vines at our Soliloquy Vineyard. Learn how our Soliloquy Vineyard is entirely unique to Flora Springs and distinct from more common Sauvignon Blanc vineyards in Napa Valley.
Shoot thinning is a process in which any unnecessary shoots are removed—typically those in the lower regions of the vine. Removing select shoots allows the vines’ energy to be directed towards the primary shoots, which will ultimately bear fruit.
Leaf thinning is conducted for a variety of reasons, particularly in wet years like this one when the canopy tends to be vigorous. Too much vigor can lead to vegetative characteristics—which we don’t want! Removing the leaves curtails this issue. Leaf thinning also opens up the canopy, allowing increased air flow and quicker drying in the event of morning dew or rain, and to prevent mildew in humid conditions. This opening of the canopy also increases light penetration—which is needed for photosynthesis. Sunlight exposure improves grape quality, protects the berry, and also elevates the phenols and polyphenols that are responsible for the color, taste, and flavor of the wine.
While this work is being done, the crews are also positioning the shoots. The shoots may be 24”–36” at this point. If we are working in a vineyard that has a vertical trellis system, there will be a series of horizontal wires running from one end of the row to the other. As the vine grows, the shoots will be tucked into the wire trellis to allow for what is commonly referred to as VSP, or vertical shoot positioning. This allows further opening of the canopy. There are other types of trellises, but VSP is the primary system implemented in most Flora Springs vineyard blocks.
After the initial thinning pass, each block will be monitored in the weeks to come to determine when/if additional passes are to be made.
Looking out across the Flora Springs Estate on this warm and sunny day, one would never know that fires were ravaging through parts of the Napa Valley just a year ago. From our vantage point, all appears to be as it always has been – green, lush and beautiful as always…something we often take for granted, but something we were reminded last year, that we shouldn’t.
As noted in previous updates, we didn’t have a crystal ball but we completed harvest on October 7th last year – the day before the fires began. This year, we are currently about one-third of the way through harvest. Last year we experienced several heat waves that sped things up a bit, while this year we have experienced a nice, consistent temperature range. We did see a small amount of rain last week, but fortunately it came and went without any effect on the vineyards.
In regards to harvest dates, people often ask, “Is this an average harvest?” or “Is this a “normal harvest?” However, “average” and “normal” are not necessarily synonymous. Average is a term that can be quantified. That is, if you have four decades of harvest dates, you can simply divide by 40 and find your average harvest date. But, normal depends on who you ask – and how long they have been farming grapes, and the conditions in which they have been doing it.
As you know may know, we sell a lot of our fruit to other wineries. Some of the newer wineries have only experienced harvests during the drought years, so their version of normal has been marked with early harvest dates and early completion dates. But if you ask someone who has been around for a while, you’ll hear a different definition of normal. Prior to 2008 for instance, very seldom – if ever, were grapes harvested before Labor Day, and seldom – if ever – was harvest completed before Halloween. So while we are only one-third of the way through harvest, it’s really more of the “normal” for us, if you don’t take into account the recent years of drought.
We have completed harvesting most all of our whites at this point: 100% of Pinot Grigio, 100% of Chardonnay and 96% of Sauvignon Blanc. We left a small amount of our Sauvignon Blanc on the vine to make a late harvest wine.
We will have pressed off all of the reds we have received thus far – Merlot and Sangiovese – prior to harvesting our next grapes on Monday. We will be receiving the first of our Petit Verdot and Cabernet Sauvignon starting next week.
Flavors are really starting to develop in the vineyard, and we’re looking forward to making some outstanding wines with what Mother Nature delivers!
Tuesday, September 18th, 2018 was a day of “firsts” at Flora Springs: the first day we harvested Chardonnay as well as the first day of harvesting reds. We hand-picked our Lavender Hill block of Chardonnay in Carneros in the morning. The ½ ton bins were delivered to the winery where the juice was pressed out of clusters. The fruit tasted terrific! It’s very tropical, with nice apple and pear characteristics and a good acid balance.
The Chardonnay juice resided in a holding tank at 45°F for 24 hours, and then we moved it to another tank and inoculated it with yeast. Once fermentation gets going we’ll move the juice to various fermentation vessels, including puncheons (a large 130-gallon oak barrel), standard 60-gallon oak barrels, as well as concrete eggs, which some of you may have seen in our cave. We ferment our Chardonnay at cool temperatures to retain aromatics. It’ll take upward of three weeks to ferment the juice to dryness.
We also picked two blocks of Merlot on Tuesday, both from the Rutherford appellation: our Windfall Vineyard at the very southern end of the Rutherford appellation, and a block on the Komes Ranch at the winery’s estate, at the very northern end of the appellation. Block B of the Komes Ranch is the first block to your right as you enter the estate, and the eastern section of this block is always about a week to 10 days ahead of the rest, so we pick this section first. Like the Chardonnay, the Merlots look and taste terrific. In both blocks the grapes were very well balanced on the vine and taste fantastic!
With the Merlot, we “cold soak” the fruit for about four days at 50°F. During that time we do “pumpovers,” where we pump juice from the bottom of the tank and irrigate the cap that forms at the top of the tank. This helps us get color, flavor and tannin from the skins. On the fifth day, we warm up the tank and inoculate the juice with yeast. We ferment at about 85°F, pumping over anywhere from one to three times a day depending on the stage of fermentation.
The cooler than normal temperatures we’re seeing this harvest is allowing fruit flavors to develop slowly on the vine without the spike in sugar – which is a great thing! When we can obtain physiological ripeness with lower sugar, it’s a gift from Mother Nature. We’ll have a bit of a break before we bring in the next grapes, but we expect to harvest some Sangiovese and additional Merlot within the next week. It looks to be another magical harvest!
Well it’s that time of year again when we start thinking about the upcoming harvest. In the winery we are just finishing up the last of the bottling season. We have a couple more Single Vineyards to go, and Trilogy, and that’s about it.
Preparations are being made in the cellar for the upcoming harvest – equipment maintenance, bin cleaning, sorting table set-up, etc. We’re starting to feel the buzz!
In the vineyard, as you will see from the photos, we are fully underway with veraison. About 80-90% of the grapes at the Komes Ranch (our Estate Vineyard) are through, except for the Cabernet Franc and Petit Verdot, which are only at about 10%. Most of the Cabernet blocks started veraison around July 24th. They progressed slowly during the last week of July, but colored quickly the first week of August. Our Crossroads Ranch is similar in veraison percentage, although our Sauvignon Blanc is through 100%.
While we have had high afternoon temperatures, most mornings have been relatively cool and/or foggy, and we haven’t experienced the intense heat we had at this time last year. Current vineyard activities include cluster counting (to get accurate crop estimates), fruit thinning (for a more balanced vine that leads to greater fruit quality), leaf thinning (to open up the canopy to allow more exposure and better air flow), measuring vine water status, and scouting for canopy or fruit problems. We also do leaf blade sampling – taking samples of the leaf tissue to determine if there are any nutrient deficiencies. Finally, we’re putting up shade cloths on specific vineyard blocks that are more vulnerable to direct sunlight to protect clusters from sunburn.
We’re seeing a somewhat heavier than normal crop load this year, which is probably more like an average crop load in that we’ve had many years of below average yields due to the drought. So far everything is looking terrific, and we look forward to another great harvest!
The cool and rainy spring slowed the start of the growing season at all of the Flora Springs ranches. Bud break started several weeks later than the past several harvests, however, this additional span provided more time for the vineyard crew to conduct other activities. One of which was to apply a compost tea to all of the ranches to stimulate soil microbial populations. Discing has recently been conducted at all the ranches as well. Jenny Rohrs, our Viticulturist, is examining the vines block by block to prioritize which ones will be suckered and leafed first.
In the winery, we are just finishing up our annual “Musical Barrel” routine – whereby, we move all the past years vintage into the cave, and move the previous year’s vintage (2016 in this case) into our barrel room. As noted previously, this enables us to draw from these barrels more efficiently when making blends prior to bottling. We continue to top the barrels in both the cave and barrel buildings. The wine experiences a certain amount of natural evaporation – roughly 5% or more over the barrel aging process. To ensure the barrel does not have any headspace, which would result in oxidation over time, we top them up every 3 weeks throughout the entire aging period. We are also getting into the start of the bottling season. We have bottled the Pinot Grigio and Rosé, and will be bottling the Sauvignon Blanc and Chardonnays over the next several weeks.
We’re excited to release our first wine from the 2017 vintage, our 2017 Napa Valley Pinot Grigio. 2017 was a momentous year in Napa Valley, and we know there will be a lot of curiosity about the vintage. Following is our take on the growing season and vintage, including the wildfires that affected so many in our community. Despite many challenges, we think that 2017 will go down in history not only for the wildfires but for the high quality of the 2017 vintage and wines.
2017 began with winter rain, and lots of it, enough to fill reservoirs, replenish groundwater and bring a five year drought in California to an end. Our spring weather was mild, and due to the abundance of water the vines experienced vigorous growth. We were vigilant about canopy management, going through our vineyards and removing excess leaves to ensure the developing grapes had adequate sunlight and air flow. With just a few summer heat spikes, it first appeared that harvest would proceed at a normal pace, but a heat wave over Labor Day weekend hastened picking during the first two weeks of September. Cooler temperatures arrived in mid-September, giving our red fruit extra time on the vine. Overall though, harvest was early in 2017; the last of Flora Springs’ grapes were harvested on Saturday, October 7.
Of course it’s impossible to look back at the 2017 harvest without remarking on the tragic wildfires that affected Napa Valley and neighboring growing regions. At Flora Springs we are enormously grateful to the first responders, law enforcement, community leaders, organizations and volunteers who worked tirelessly to keep our communities safe. We are also incredibly blessed, or perhaps lucky, that our grapes had all been picked prior to the start of the fires on October 8. We were not alone in this good fortune. Damage to Napa Valley wineries and vineyards was not widespread, as the fires burned predominantly in the forested hillsides. The Napa Valley floor between Highway 29 and the Silverado Trail – where our estate winery and vineyards are located – saw little to no impact. In fact, less than 10 percent of Napa Valley’s wineries and less than 8 percent of vineyards experienced direct damage from the fires, and it’s estimated that 90 percent of the total grape tonnage was picked before the fires started.
Still, we know that wine enthusiasts will have lingering questions about the effect of the fires on the grape harvest, and particularly about what is known as smoke taint. A brief explanation: a wine with smoke taint will have a distinct, unpleasant taste that is often compared to a campfire or ashtray. Unlike “smoky aromatics” that might arise from a wine’s contact with an oak barrel, smoke taint is strong and acrid, dominating the sensory characteristics of the wine. Smoke taint can occur when un-picked grapes come into contact with wildfire smoke; the smoke penetrates the grape skins and its compounds can be activated upon fermentation. In this way, even grapes that do not smell or taste smoky can yield a smoke-tainted wine. Rest assured that the few Napa Valley vintners who harvested fruit after the fires were hyper-aware of the possibility of smoke taint and have done everything possible to ensure only the highest quality 2017 wines go to market.
Now back to the quality of the 2017 vintage: for the vast majority of vintners who harvested their grapes prior to the fires there’s a shared sense of excitement about the wines from 2017, most of which are still in barrel. Says Winemaker Paul Steinauer, “Although our yields were somewhat smaller, the 2017 wines are already showing concentration and richness. The whites have bright, fresh flavors and the reds are saturated in color with powerful fruit flavors. There’s no reason to believe this vintage will not rank among the finest of the decade.”
Looking back, the 2017 wildfires challenged our community in innumerable ways, but also demonstrated our shared spirit of strength and resilience. At Flora Springs, in addition to being humbled by our good fortune and the outpouring of generosity from our friends around the world, we’re excited to open the chapter on the 2017 vintage.
We have officially picked all of our Pinot Grigio and Sauvignon Blanc for the year. We started the Pinot Grigio on August 15th, and finished the Sauvignon Blanc on August 31st.
We then started harvesting the Lavender Hill Chardonnay in Carneros on September 6th. The very next day, we received Merlot from the Estate. This is the earliest date on record for reds.
The last week was pretty crazy…Phoenix-like temperatures in the 115 degree range! On top of that, the valley was blanketed with smoke from a fire burning in Butte County. Fortunately, both have subsided and we are back to average harvest temperatures once again…at least for the time being.
We will be bringing in additional Merlot, as well as Petit Verdot from Oakville, on Monday and Tuesday. Then we will finish up with the last of the white grapes on Wednesday.
The harvest has been pretty fast and furious thus far – keeping things exciting. We were very proactive with our irrigation regimen before and during the heatwave, so the fruit is still in excellent condition. We are extremely pleased with the quality thus far, and expect to make some fantastic wines!

The winter, with its abundant rain and the ensuing growing season that was perfect for ripening wine grapes has many growers optimistic about the 2017 harvest. For some, workers are already harvesting their sauvignon blanc and chardonnay grapes; others, though, are waiting for the first grapes to cross the crushpad…
Oakville – Linda Neal, grower, Tierra Roja Vineyard, “Yount Mill kicked off the Oakville season on Aug. 9, harvesting for sparkling wines, with other white varietals quickly following, reports Kendall Hoxsey-Onysko. Turnbull follows with sauvignon blanc at the winery on Aug. 23. Winemaker Peter Heitz writes, “The flavors are fantastic!” Flora Springs may have started two days later, but did so with a saber flourish as winemaker Paul Steinauer christens the first load…”
Over that past few weeks our vineyards have been abuzz with activity. As farmers, our family constantly tends to the vineyards which means meticulous care for every vine throughout our properties in Napa Valley.
With the immense amount of rainfall received over winter, we are seeing a lot more vigor than in previous vintages. Earlier this month we kept busy with leaf removal and shoot positioning to foster adequate light through the canopy and properly see each cluster to maturity. Things are looking great out there and we anticipate a bumper crop for the 2017 vintage.
Over the years, my family has acquired nearly 350 acres of vineyards – which means we have spent much time planting and replanting vines. The newest of late, is the replanting of a 15-acre fallow block on our Crossroads Ranch to Cabernet Sauvignon Clone 2. We anticipate this vineyard to come to fruition in the next 3-to-5 years with excellent Oakville fruit. Stay tuned!
“Well, it’s that time of year again – The drought appears to be behind us, at least for the moment. Since the New Year, we have received more rainfall than we average for the entire year. Fortunately, all of Flora Springs vineyards drain quite well, and this has supplied much needed water to top off all of our reservoirs as well as adding to our water table. Between the rains, we did experience some warm days. This is when the starch in the vines post dormancy, converts to sugar, where sap begins to flow through the vine. As the days become warmer, buds start to swell, and finally burst, creating a new shoot.
What you see in this picture is bud break on our Malbec vineyard at Komes Ranch at Flora Springs Estate. In about 6 months, grapes from these vines will make their way to the winery, and eventually find their way into Trilogy.” – Winemaker Paul Steinauer
