This January, Castello President Georg Salzner and Winemaker Peter Velleno planted our first cork tree. Native to southwestern Europe, the Quercus suber cork oak tree can grow up to 100 feet tall, and is sure to thrive in the Mediterranean climate we enjoy here in Napa Valley.
Wine Corks are made from the bark of the cork tree, which needs to be stripped and peeled off by hand. Cork trees are typically harvested every seven years, and are a renewable resource since the tree is not cut down and only the outer layer of bark is removed. It takes a cork tree 25 years to reach maturity before its bark can be harvested, and we are looking forward to our first Castello cork harvest in 2042!
Winemakers weigh countless factors and make innumerable decisions every day for months on end to create a single vintage of a single wine, and, as you know, at Castello di Amorosa we make much more than a single wine. We will continue to monitor each wine, and make slight adjustments, up until the day it is bottled. Once the wine is in the bottle, that’s it; that blend had better be right because there is no going back. Bottling can be a bit stressful because of that finality. Yet, it is also a relief. So many things can go wrong in winemaking (not to mention the vineyard!). The entire winemaking and cellar team have to look out for each and every barrel at the Castello. Even one bad barrel, left unchecked, could wreck an otherwise outstanding blend. Oxidation, bacterial spoilage, leaking barrels… when that cork goes in all of those worries go away.

Bottling has to be perfect. It is just as true for delicate white wine like Pinot Grigio that will be consumed young as it is for our reserve Il Barone Cabernet Sauvignon that we hope will stand up to decades of cellaring. This is the main reason Dario decided to purchase the Castello bottling line; many wineries as small as us do not own their own lines. They either bring in a mobile bottling line (truck and trailer) or ship the wine offsite for bottling. Having your own equipment is very expensive to start with, and then you need to have staff that knows the intricacies of your machines and also staff to perform the non-stop Quality Control checks. The benefit, however, is so great that Dario did not hesitate when making this investment.
We hand wax each bottle of our Il Barone and La Castellana Reserve wines to give it a traditional look and create a tamper-proof seal.
Here at the Castello we have complete control over our wines. Though most of our bottling happens in the summer before the Harvest, we bottle something nearly every month of the year, in small batches, ensuring that each individual wine is bottled when it is ready. Not sooner, when a wine might be underdeveloped and not fully expressive, and not later, when a wine might become “tired” before it even gets in a bottle. This type of flexibility in scheduling is simply not possible without bottling your wine on-site with your own bottling line and staff.
Empty bottles waiting their turn to be filled with the newest vintage
The Castello di Amorosa bottling line has a special type of bottle filler called a counter-pressure filler. This type of filler is commonly used at modern breweries to fill beer bottles, but seldom seen at wineries. The reason for this is that beer is even more susceptible to spoilage than wine is, and it is extremely sensitive to oxygen exposure. The counter-pressure style filler is unmatched in its ability to prevent oxygen from getting in to the product while also maintaining a sterile bottling environment. It also came with a steep price tag (much more than a traditional filler), but if you know Dario, you know that he is willing make just about any investment to support wine quality. This type of bottling line also offers another benefit: the Castello di Amorosa famous dessert wine La Fantasia. The unusually high level of “spritz” in that wine makes it impossible to bottle with a traditional wine bottle filler. The Castle just would not be the same without La Fantasia!

While bottling there are a number of Quality Control checks that the Castello staff monitors: temperature of the wine, dissolved oxygen, fill level, vacuum of the corker, label placement… You really do have to pay close attention, as you only get once chance to get it right. After bottling we perform our own in-house microbiological plating of the wines to make sure there was no contamination. Once we see those results, we can finally stop holding our breath and appreciate all of the work that went in to each and every bottle of wine. If bottling goes smoothly and stays on schedule, we might even get a little time off before the next Harvest starts!
Winemaker, Castello di Amorosa
It has often been said that if Cabernet Sauvignon is king here in Napa Valley, then Chardonnay is queen. Chardonnay has reigned supreme among white wine grapes in California since the Judgment of Paris in 1976, when Chateau Montelena’s 1973 Chardonnay trumped the French competition in a blind tasting and helped to put Napa Valley on the map of world-renowned winegrowing regions. Today, there are over 100,000 acres of Chardonnay vineyards planted throughout California, and the varietal remains one of the top white wines consumed by Americans each year.
One of the reasons for Chardonnay’s popularity is the wide variety of styles it can be crafted in, based on where the grapes came from and how the wine was aged. While the majority of Chardonnays are aged in oak barrels, unoaked Chardonnays are rapidly increasing in popularity due to their brighter, fruitier notes, and both aging styles offer a wide range of complexity in the finished wines.
Chardonnay at the Castello
Here at the Castello, we produce two Chardonnays every year from two select cool climate vineyards in California. Our Napa Valley Chardonnay fruit comes from own estate vineyard in the Los Carneros AVA (American Viticultural Area) in the southern end of the Napa Valley, which is meticulously tended to by our Vineyard Manager, David Bejar, who has worked with Dario Sattui and our winemaking team for the past 17 years. Our Bien Nacido Vineyard Chardonnay comes from the iconic family owned vineyard in the Santa Maria Valley in Santa Barbara County, along the Central California Coast. In using these two cool climate vineyards to produce our Chardonnays, we hope to showcase the unique terroir of each region while utilizing both traditional and innovative winemaking techniques.
Our Bien Nacido Vineyard Reserve Chardonnay
All of our Chardonnay is harvested at night in order for the fruit to arrive at the Castello cold, which preserves the its delicate aromatics and natural acidity. Once the fruit gets to the winery, the whole grape clusters are placed into our two pneumatic, or “bladder” presses, which gently presses the juice from the skins and seeds. The juice is then pumped into Burgundian French oak barrels, where it ages for 8-10 months. We use 50% new and 50% second use French oak barrels on our oak-aged Chardonnays, which provides a balance between showcasing the terroir of the vineyard, acidity and fruit characteristics of the varietal, and the subtle notes of toast and spices that come from each individual barrel.

After the wine has undergone primary fermentation, which converts the sugars in the juice into alcohol, our winemaking team then selects a specific number of barrels to undergo malolactic, or secondary fermentation. Here, the malic acid in the juice is converted into lactic acid, which gives Chardonnay its signature creamy mouthfeel (think “lactose” like milk). Roughly 40-60% of our Chardonnay barrels undergo malolactic fermentation, depending on the characteristics of the vintage and the acidity levels of each blend.
La Rocca Chardonnay – A new twist on a classic wine
If you have visited the Castello on a guided tour, you may have noticed our concrete fermentation eggs in the Grand Barrel Room, our 12,000 sq ft cross vaulted room three levels underground. We have been using these concrete eggs for the past several years to craft select single vineyard white wines like our Ferrington Vineyard Dry Gewurztraminer and Tyla’s Point Pinot Bianco, and beginning with the 2013 vintage we are also fermenting and aging a select amount of our Bien Nacido Vineyard Chardonnay in one of these eggs. We have named this unique, limited-release wine “La Rocca,” which means “The Fortress” in Italian. The egg shape allows for a natural suspension of the lees (sediment) compared to aging in traditional stainless steel tanks, without imparting any flavors or aromas found in oak barrel aging, and the higher acidity and tropical fruit characteristics of the Bien Nacido Vineyard Chardonnay made this fruit a perfect choice for aging in these unique vessels.

We are excited to make two Chardonnays from this historic vineyard in both French oak and concrete, as these two differing styles help to show the versatility of the varietal as well as the vineyard. Our La Rocca Chardonnay from Bien Nacido Vineyard is released each year to several of our shipping clubs, and we look forward to showing off the versatility of this beautiful Burgundian grape with our trio of California Chardonnays with each vintage!
Our Pinot Noir and Chardonnay harvest for sparkling wine is now complete, and early Pinot Grigio grapes have also been pressed and are now cold-settling in tank. Predictions of an early harvest have proved to be true, so we are preparing for Pinot Noir, Chardonnay, Muscat and dry-farmed Zinfandel to follow quickly into the winery.
Quality is very high, and we expect a stellar vintage in Napa Valley in 2014. Some varieties are yielding a bit light while others may come in a bit heavy. Cabernet Sauvignon (pictured above) looks great; Chardonnay and Pinot Noir yields are expected to be average, while Syrah and Merlot clusters are sizing up and will be at or above expectations. The cool weather over the last two weeks have given the vines a chance to recover from the summer drought conditions, and I am really excited about flavor development and acid profiles in the grapes. We want to extend the “hang-time” a bit for reds, so that the skin and phenolic maturity reaches its peak before harvest. Given our current weather everything looks really good, and 2014 should be another excellent year!
If you have been lucky enough to explore our Grand Barrel Room on a tour and tasting recently at the Castello, you may have noticed a few new additions to the stunning 12,000 square foot room. Right next to where our guests have the chance to taste wine straight from the barrel, there sit several large, concrete, egg-shaped containers. These are fermentation tanks, and they are used to ferment a special selection of the Castello’s award-winning wines.
Concrete? You might ask. What can concrete do for wine? Well as it turns out, concrete is a fantastic alternative to oak or stainless steel in winemaking. Without the “oaky” impact on a wine from barrel aging, the concrete allows the wine to retain its fruity characteristics and the inherent characteristics of the grapes are allowed to shine, making it an especially useful fermentation method for showcasing the terroir of single vineyard wines.
Concrete eggs are an interesting mix of ancient and ultra-modern winemaking techniques, since the first wines were actually fermented in pottery jars called amphorae. The egg shape is a newer modification, which allows the wines inside to have a natural convection current as the carbon dioxide released during fermentation helps to naturally stir the wine and mix in the sediment, or lees.
“Graeco-Italic” Wine Amphora, 2nd century B.C.
We originally had two concrete eggs in our Grand Barrel Room, and focused on several single vineyard wines, including our Ferrington Vineyard Dry Gewürztraminer and Tyla’s Point Pinot Bianco. These aromatic varietals work especially well with this fermentation method, because the concrete enhances the floral aromas and even increases the mineral characteristics in these wines. The elegant complexity of these wines from their fermentation in the eggs has led to them both winning high praise from tasting panels and our guests.
Our 2011 Ferrington Dry Gewurztraminer
This past year we have also produced a limited amount of Chardonnay, called “La Rocca” or “the fortress.” Our Winemaker, Peter Velleno, explains that “the reason for the Chardonnay is that the use of concrete (or more specifically the lack of oak barrels) allows the flavor of the vineyard to be the star. Chardonnay needs to have a rich mouthfeel, so it makes sense to try it in concrete, where there will be no oak flavors or aroma, but still the benefits of aging on the lees.” Aging wine on the lees, or the yeast and sediment that settles to the bottom of the barrel during fermentation, imparts a creaminess and complexity that can’t be found in stainless steel. This year we are excited to be fermenting some of the Chardonnay fruit from the Bien Nacido vineyard in one of our eggs.
So keep an eye out the next time you visit the Castello, and if you take a tour down into the Grand Barrel Room you’ll be able to check out this unique fermentation technique that helps to make our Italian-style wines even more incredible!
During the Harvest season, there are always exciting things going on around the Castello, and today on the Crush Pad was no exception. Today, for the first time at the Castello, our winemaking team reserved a small lot of our Don Thomas Vineyard Cabernet Sauvignon for fermentation directly in French Oak Barrels.
Traditionally, the fermentation process takes place in stainless steel tanks, where the must (skins and seeds of the grapes) are cold soaked with the juice before yeast is added. The cap, or layer of skins and seeds that get pushed to the top of the tanks from the activity taking place during fermentation, is broken up by either the punch-down or pump-over method, both of which ensure an even distribution of the color and flavors we wish to impart into our red wines. After five to eight days in these fermentation tanks, the juice is pressed from the skins and seeds and pumped into French Oak barrels for aging in the Castello’s extensive underground cave and cellar system.
Barrel fermentation means that the freshly destemmed grapes and their juices are pumped directly into French Oak barrels whose heads have been removed. Dry ice is added to cool the berries before the barrel heads are secured to seal in the must. The barrels are then laid on a rack that allows them to be rolled back and forth daily to ensure the cap stays moist and the oak is evenly introduced to the fermenting must and juice. Typically, two full barrels of must and juice will amount to one barrel of wine. The process of fermenting the juice in oak barrels helps to impart an added silkiness to the tannins and a rounder, more lush mouthfeel, especially to Bordeaux varietals. This extremely labor-intensive method of fermentation is typically reserved for only the most exclusive of wines, and the highly-acclaimed Cabernet Sauvignon from the Don Thomas Vineyard is an exceptional example of the quality of grapes deserving of such treatment.

This is the time of year when winemakers and vineyard managers start paying close attention to weather patterns. Although long periods of extreme cold and sub-freezing temperatures can always cause distress in a vineyard; frost is particularly damaging in the early spring. Once bud break occurs, spring frosts can kill the young shoots potentially destroying a crop. If you visit wine country in early spring you may spot a few different methods utilized by vintners in attempts to combat frost damage. Most preventative measures are expensive and vary in effectiveness, but, the financial loss of frost damage is extreme.
The least utilized and possibly least effective is burning oil in a smudge pot. The smoke and heat generated is hopefully carried over the vineyard by the wind forming a warmer protective blanket. As the heavier cold air sinks, the warm blanket of air protects the shoots.
A solution that seems just as drastic but that has actually proven viable in some vineyard locales; spraying the vines with a fine mist of water. As the water freezes it forms a protective layer of ice insulating the young shoots by trapping the heat, (think of an igloo or an ice cave). Since Napa Valley’s Mediterranean climate doesn’t generally dip below 25 degrees Fahrenheit, this method shows promise as it is environmentally less invasive and more economically viable. A negative for using water is fairly obvious but worth noting: you are using water, which can be scarce or completely unavailable in remote vineyards.
The most common and visually the most obvious method in use can be viewed off Highway 29 and along the Silverado Trail. What looks like windmills are actually wind machines, which move air over vineyards to keep the coldest air from settling on vulnerable, young shoots. The heavier cold air mixes with the warmer air, being moved by the wind machine, creating a slight elevation in temperature which is often just enough to ward off frost as long as that temperature is above 28 degrees Fahrenheit. However, I live close to one such wind machine and I see it as only partially effective. While it prevents frost from developing in areas directly in the path of said turbulence, my personal observation is the outlying areas are often blanketed with frost. Another fact to consider…..wind machines are essentially propellers that run on fuel so they can be expensive to run and the noise level can be extreme – especially in the wee hours of the morning when they are typically used. *yawn*
Does a foolproof solution exist? Well, if you have an opportunity when driving in the valley, look to the hills. It is rare to find any method of frost control on sloped vineyard sites. Dense cold air naturally drains off the hillsides and settles onto the valley floor quite often rendering the hillsides unaffected by frost.
In this north end of the Napa Valley we are fortunate. With the Mayacamas Mountains to the West and the Vaca Mountains to the East, some of the most prestigious viticultural land in the world has been created. Castello di Amorosa’s Il Barone and La Castellana wines are crafted from Cabernet Sauvignon vineyards on Diamond Mountain, part of the famed Mayacamas range; above the fog line, drenched in sunshine and relatively unharmed by frost.
As we continue to progress in viticulture methodology one fact holds true – Mother Nature will always have the final word.
And with that my final word – Cheers!

Consulting winemaker Sebastiano Rosa has been here during harvest working with Brooks Painter, Director of Winemaking, and Peter Velleno, Associate Winemaker. We welcomed some friends to meet him on October 9, where he shared wines from his winery in Sardinia (Montessu and Barrua from Agricola Punica). It was also a chance to taste several vintages of La Castellana, Il Barone and Il Passito with him.
Napa Valley's Castello di Amorosa today announced that Sebastiano Rosa, winemaker at Tenuta San Guido- producer of Sassicaia- one of Italy's leading Bordeaux-style red wines has joined the winemaking team of Brooks Painter, Peter Velleno and Laura Orozco. Sebastiano will travel from his home in Bolgheri, Italy to consult with Painter's team on all aspects of Castello's Italian-style red wine program.
"From the vineyard to the glass, the addition of Sebastiano Rosa will bring an international perspective to our program," said Georg Salzner, President of Castello di Amorosa. "Our history is Italian; our winery is Italian style so it's natural that we partner with Sebastiano to create unique, Italian-style wines."
Rosa, the stepson of Nicolo Incisa della Rocchette whose family owns Sassicaia, brings an extensive wine background to the team. Upon graduating from U.C. Davis in 1990, Sebastiano participated in the 1991 harvest at the storied Chateau Lafite Rothschild.
From 1992 until 2002, he was General Manager at Tenuta di Argiano in Montalcino where he worked with legendary winemaker Giacomo Tachis, considered by some to be the father of the renaissance of Italian wine. While Sassacaia was the first wine in the renaissance, his other label, Solengo, was the number 8 wine in Wine Spectator's Top 100 and received 96 points in only it's second vintage.
"We are excited about Sebastiano's collaboration and contributions to our winemaking," said Brooks Painter, Castello's Director of Winemaking. "At Castello di Amorosa we are only interested in producing top quality wine. Sebastiano will help us continue to craft exceptional wines with distinct character and structure while respecting the unique Napa Valley terrior."
Rosa, the Technical Director of Tenuta San Guido from 2002 until 2011, managed the Sassicaia cellar where he started the second and third labels for Sassicaia- Guidalberto and Le Difese.
In many parts of the country, winter is still hanging around, but not in the Napa Valley and certainly not at Castello di Amorosa's vineyards where budbreak, the first emergence of shoots that will ultimately bear fruit, occurred earlier this week. Sangiovese showed it's buds first; Primitivo, Merlot and Cabernet Sauvignon vines will budbreak next. Budbreak occurs when the vines wake from their winter dormancy and begin to show signs of life. Water drawn up through the extensive root system appears on the cuts made by pruning. This is followed by the emergence of tiny buds. Leaves eventually unfold- a fresh start to a new growing season.
Working in the vineyard is a labor of love. Pictured below is Mario Martinez, Vineyard Crew Leader. His gentle hands prepare the Primitivo vines for the growing season.
