Solar at The Castle

We invested $1.4 million in a 450-kilowatt solar power array. The massive 1162 panel system was completed in January of 2022 and is situated on a spot which had been a forested slope but was significantly burned in the Glass Fire that hit the Napa Valley in 2020.

“This enormous investment is an important element of our commitment to become as self-sufficient as possible while minimizing our carbon footprint and helping with the climate change crisis. We expect this will offset our energy usage around 80%,” explains Georg Salzner, President, Castello di Amorosa.

Castello di Amorosa partnered with Centrica, Recolte Energy, 127 Energy and DEIF on the multiple components of this installation. 127 Energy designed the 556-kilowatt battery storage microgrid. Using advanced and remotely accessed power controls, the solar microgrid provides Castello di Amorosa with an independent power supply during frequent utility grid outages. During times of normal operations, the solar microgrid reduces utility energy charges and demand charges, resulting in significant operational savings for the winery.

“Due to fire risks and skyrocketing power prices, commercial business owners in California are taking matters into their own hands. Castello di Amorosa, Centrica Business Solutions, and Sungrow were great partners on this project and our collaboration exemplifies how innovative teams can solve daunting environmental and energy-related challenges,” said Mark Crowdis, CEO of 127 Energy. “The battery storage microgrid provides a striking juxtaposition of resilient, clean energy technology against the backdrop of historic castle grounds,” Crowdis added.

Other examples of Castello di Amorosa’s environmentally friendly programs and practices:

· Napa Green Certified: the winery has been Napa Green Certified since May 2018 (renewed in June 2021). Being Napa Green Certified’s requirements include LED Lighting, using a minimum of 50% recycled paper in the winery offices; using recycled cardboard and recycled pulp for shipping (instead of Styrofoam), using green certified cleaning agents and hand soap; using recyclable/compostable plates/flatware.

Bio Microbics Micro Fiber filtration system: the winery treats all of its processed water (water used during production of wine) and re-uses it for landscaping. Since 2017, the winery has treated and re-used over 5,000,000 gallons of water.

· The winery has begun composting as of January, 2022.

· Napa Ride Share program: the winery pays employees to carpool, thus eliminating more cars on the road.

Castello di Amorosa owns and farms 130 acres in Napa, Sonoma and Anderson Valley.

A History of the Project – Part 2

By 1994, I had the person willing to teach us medieval building techniques, Fritz Gruber from Austria, and I had the quasi-experienced builder from Italy, a Dane named Lars Nimskov, who understood what I wanted to do and was willing to stay the duration.

Gruber also sold ancient, handmade European bricks. Further, I had spent years, even before I knew I was actually going to build something, researching where to get raw materials. I searched in South America, Israel, and in much of America and Mexico and throughout Europe. Over a duration of many years, I had acquired a wide source-list of addresses for the materials I needed to build my castle.

In the 1980’s and 90’s, I was going to Italy for as long as three months at a time. In fact, in 1989, I moved to Rome for six and a half months. While there I made a promise to myself, a promise I had considered for years, to purchase an Italian property before departing to Rome. With little time left, I made a frantic search over the remaining weeks. I decided I didn’t want a property in Lazio, the region of Rome, instead deciding on Umbria or Tuscany, which I found to be infinitely more beautiful.

My First Castle … In the Florentine Hills

I went with several realtors day after day, from morning to night, looking at properties. Finally I found it, a small 12th century castle, Castello di Panzalla, just 12 miles outside of Florence in the hills of Chianti Classico and that had once belonged to the cousin of the King of Italy. I bought it, along with 220 acres and four farmhouses that came with the property. I negotiated the entire transaction in Italian with out a lawyer, relying on the German realtor living in Chianti.

I was full of exhilarating ideas to restore the castle to its former glory. But, a short time after I returned to the U.S., the castle was severely vandalized and burglarized. Ancient, dated plaques were ripped out of walls, old roof tiles and all the 300 year old interior doors stolen, virtually every window smashed, ancient coat of arms torn from walls, the entrance door destroyed, hand-chiseled pavement stones dug up. Anything of value and portable was hauled away. I was devastated. My dream had been destroyed; and I didn’t want Castello di Panzalla any longer. I put it up for sale. I thought selling the property would take ten years. There are not a lot of buyers for castles.

The following year, 1990, I went looking for more property with the German real estate agent, whom I wholeheartedly trusted, never believing him to be absolutely disreputable as I was later to discover. For three weeks, night and day, I searched. One day I came upon a 10th century, fortified, Augustinian monastery dominating the hillside in the countryside just 23 miles east of Siena on the road to Perugia. I knew within a half an hour that I would buy it. The only question was the price. It was totally run down, with mounds of garbage everywhere. My wife hated it, but I could envision what it had been and what it could be; and I loved it. Out of what was to become my bedroom window, I had the most perfect view in the world — golden fields, stone farm houses, lush vineyards, rolling hills, two castles and another monastery. I was in heaven.

After buying my monastery and naming it Monastero di Coriano, my dog Pipo and I set about restoring it. I could have written “Under the Tuscan Sun,” myself, but with some different twists. It was by using Monastero di Coriano as a home base that I began diligently researching medieval buildings.

I would get on my motorcycle or in my car before dawn, day after day, with a backpack containing a hammer, a tape measure, camera and film and sketchpad and pencils. I would return home after dark having seen and thoroughly inspected, studied, measured, sketched and photographed every detail of what I had discovered. The hammer was used in case I had to break in.

It must be remembered that twenty years ago there were a lot of abandoned farm houses, palaces, churches and castle in the countryside of Umbria and Tuscany. The rural population had left en masse in the late 60’s and 70’s to escape the tedious and uncomfortable agricultural life without amenities to live in modern rented cement boxes called apartamenti in the cities, where they’d have wall-to-wall carpeting, running water, and central heating. Here they found work in factories such as Fiat or Olivetti.

As a result, there was a plethora of medieval buildings, great and small in the countryside waiting to decay or be restored. The Italians seemed to want no part of restoring them; they were happy to part with them for a song. It was mostly the English, the Germans and the Swiss who discovered these treasures and began buying them up cheaply to restore. In short, it was foreigners who saved the countryside of central Italy.

When I couldn’t walk or pry open a door or window, my insatiable thirst for knowledge about these buildings forced me to be clever. I would dress up in a suit and tie and go to prominent realtors pretending to be a wealthy person wanting to buy a castle on the market. I was even given ancient building plans, but of course, I bought none of these properties. I only wanted to study these masterpieces, and I had no idea why. Something inside me compelled me to do it.

Without realizing it, I was slowly acquiring the knowledge that would enable me to build my own castle….
