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.
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!
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!
“To ensure we are obtaining only the most premium fruit, we have had to make the difficult decision to replant vineyards when the quality starts to deteriorate due to various forms of vine disease. Two of our Cabernet blocks in our Oakville Crossroads vineyards have recently been pulled out. This vineyard site in Oakville at our Crossroads vineyard had previously been planted to Chardonnay, and has now been re-developed and will be planted to Cabernet very soon.
This is a newly-planted vineyard, also at our Oakville Crossroads vineyards. This was formerly Pinot Grigio, and has also now been planted to Cabernet.
Crews are currently going through all of our vineyard blocks and suckering. Buds, or nodes at the base of the leaves, produce shoots called laterals or suckers. By doing this, more energy is focused on the vine – which increases grape quality. It also keeps the vine off the ground, and helps prevent unwanted molds and various insects.
The area between the nodes, the internodes, are supported with adjustable ties which are attached to guide wires. As the vines mature during the growing season, the guide wires – and thereby the vines – will be raised on the trellis system. The vines will be trained in such a way as to evenly distribute the clusters of fruit, and the canopy of leaves will protect the fruit from direct sunlight in order to prevent burn. The canopy will be open just enough to allow filtered light, as well as sufficient airflow throughout the vineyard.
Finally, we have the start of bloom in our Hillside Reserve Cabernet Vineyard.”
“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
We started the harvest on Aug 16th picking Pinot Grigio in the Oak Knoll appellation, and we just finished on Tuesday, Oct 11th with Cabernet Sauvignon from Oakville appellation – so just about a 2 month harvest.
All in all, it was a terrific harvest! We experienced a very light amount of rain that did not affect the grapes at all. We only had a few days with any unusual heat spikes. We are however, very glad to be finished, in that there is a significant amount of rain in the forecast from Friday through Monday. There are many wineries that are forced to leave their fruit out through the rains, and again, a relief to not be one of them.”

“Well, Mother Nature once again threw us a bit of a curve ball – We experienced 3 days around 100F, then it cooled off and actually had some showers on Sunday & Monday this week. The good news is that none of that has effected the grapes to any degree at all. We have harvested approximately 80% of our fruit thus far and the remaining grapes will be brought in by the end of next week. We have a handful of blocks on the Komes Ranch in the Rutherford Appellation – Cabernet Sauvignon, Petite Verdot and Cabernet Franc. We also have a few blocks of Cabernet Sauvignon at our Crossroads Ranch in the Oakville Appellation as well. We are just waiting for these blocks to garner a more complex flavor profile before we pick them.”
