Lithology Winery: Inside Alejandro Bulgheroni's Napa Estate

St. Helena, October 2026. By Greg Martellotto, founder of Big Hammer Wines. Photos: Big Hammer Wines and Lithology.

Lithology is the study of rocks. It's also the name of one of the smallest and most interesting wineries in Napa Valley: a stone winery on Meadowood Lane in St. Helena, just down the street from Meadowood, in the building that was the first home of Bill Harlan's Promontory.

The day after our visit to Hundred Acre, we drove up that lane for a trade tasting. We were greeted with a glass of Ruinart Champagne, then spent the afternoon with Spencer Dubuque, Lithology's estate manager. All told the winery makes about 2,000 cases a year, Spencer says, and its top wines come from some of the most expensive Cabernet grapes in America: Andy Beckstoffer's To Kalon, Dr. Crane and Las Piedras vineyards.

Behind it is one of the most remarkable second acts in wine. Alejandro Bulgheroni grew up on a cattle ranch in Argentina, built a fortune in energy, and started buying wineries in his mid-sixties. Today he owns about 15 of them on four continents. Lithology is his only one in Napa.

Here's everything we learned, the wines Spencer poured, and the Lithology bottles we carry.

Where We Sat: Down the Street From Meadowood, in Harlan's First Promontory Winery

The estate is small, about 15 acres by Spencer's count, on the lower slopes of Howell Mountain just past Meadowood, the resort. A stone winery sits in the middle of it, and the building has more Napa history in it than almost any tasting room in the valley.

According to the winery's history, the land was part of an 1841 Mexican land grant. In 1860 a 13-acre parcel was sold to John Howell, the blacksmith Howell Mountain is named after. In 1975 Jim and Nina Talcott planted vines here and built the stone winery that still stands. Later it became the first home of Bill Harlan's projects, including Promontory and the first vintages of the Napa Valley Reserve. Bulgheroni bought it from the Harlans in 2014 and moved in the next year.

The View From the Top

Before we sat down, we went up to the top of the estate. From up there you look straight across the floor of Napa Valley, a patchwork of vineyards and oaks, to the Mayacamas Mountains on the far side. It's one of the best views I've had from any winery in the valley. Here it is, unedited:

Turn around and the hillside is dry grass, chaparral and rock, with a few bare, blackened trunks still standing. The 2020 Glass Fire burned through this corner of St. Helena and badly damaged neighboring Meadowood. Lithology has no 2020 Cabernets.

The estate's own vineyard is tiny: about two acres of Sauvignon Blanc just below the winery, farmed organically, with Cabernet planted on the upper slope in 2021. Spencer says the Sauvignon Blanc runs to about 75 cases a year. The 2023 is sold out, and the 2024 comes out in 2027.

Inside, the tasting room is high walls of rough stacked stone, arched windows full of green, and an iron lantern chandelier hung with candles. A long table of thick, rough-sawn planks runs down the middle, with leather-backed chairs and a sitting area by the fireplace. When we sat down, there was a glass for each wine at every place, a black folder stamped LITHOLOGY, and a centerpiece that looked a lot like a slab of petrified wood.

The Cattle Rancher Who Started Over in Wine

Alejandro Bulgheroni was born in 1943 in Rufino, Argentina. His fortune came from energy. He joined his family's company, Bridas, in 1965, and Pan American Energy grew out of a Bridas venture with Amoco, later BP.

That isn't the part Spencer leads with. "We don't really talk about that much," he told me when I asked about the oil. What he talks about is the ranch. Bulgheroni grew up on a cattle ranch in Argentina that Spencer describes as about 1,000 square miles. Spencer's joke: if you eat a blueberry in South America, it probably came from there.

The food on our plates was a tribute to that ranch, built from things it grows:

• Marcona almonds.
• A crumbly linzer tart with Kalamata olives and blueberries. (Spencer's tip: eat it over the plate.)
• Braised beef brisket with a rhubarb gelée, and a gluten-free tart with rose petals and Maldon salt. It sounds sweet. It's savory.
• An apricot canapé with celery root purée and black peppercorns in a little tart shell, made specifically to go with the Chardonnay.

They were small bites, but impeccable. Not unlike the wines.

Bulgheroni always loved wine, but he didn't get into the business until his mid-sixties. When he did, he went all in. His first project was Bodega Garzón in Uruguay, now the largest of his wineries, known for Albariño and Tannat. A 2025 count put his group, Alejandro Bulgheroni Family Vineyards, at 15 wineries in six countries: Uruguay, Argentina (including Otronia in Patagonia, among the southernmost vineyards in the world), Tuscany (including Bolgheri), Bordeaux, Australia's Barossa Valley, and Napa.

In January 2026, Wine Enthusiast gave him its Lifetime Achievement award. He turned 83 in October. Spencer says the next generation is taking a bigger role, starting at Garzón.

Spencer has never met him. But he's been told which bottle Bulgheroni opens when friends come over, the one he's proudest of: the Cabernet that carries his own name.

Why "Lithology": A Winery Named for Rocks

The first vintage, 2014, was made by Philippe Melka at Vineyard 29, and the wine went out as Alejandro Bulgheroni Estate. That's a mouthful. So the winery took a new name, and Melka, who trained in geology before he trained in wine, helped choose it.

The idea is simple. Every wine comes from one specific piece of ground, and the ground should do the talking. Each label carries a different rock to stand for the vineyard the fruit came from. In the winery's words, the vineyard leads and winemaking follows.

The newest rock is red. It belongs to Steltzner Vineyard in the Stags Leap District, a 2023 Cabernet released about two weeks before we arrived. Spencer says they made about 150 cases. (Steltzner fans: Revana, which we're writing about next, bottles one too.)

Matt Sands and the Silky Style

The winemaker is Matt Sands, a New Zealander. He worked at Stonyridge and Man O' War at home, then did harvests in Napa at Screaming Eagle and at Bryant Family on Pritchard Hill, where he met Philippe Melka. Melka was too busy to be a full-time winemaker, so Matt interviewed, got the job in 2015, and has made every vintage since. Mark Pittman is his assistant winemaker. Melka and Maayan Koschitzky still consult, and Michel Rolland led the blending sessions here for a decade, until his death in March 2026.

Ask anyone at Lithology to describe Matt's wines and you get the same word: silky. Here's how he gets there.

• Slow, cool fermentations. Plenty of wineries ferment hot and fast. Matt takes 25 to 30 days at around 85 degrees.
• Concrete and wood. The vineyard-designated wines ferment in concrete tanks or old wooden foudres, which let the wine breathe.
• Lots of gentle pump-overs through the whole month-long fermentation.
• About 20 months in French oak, 70 to 76 percent of it new for the 2022 single-vineyard wines, according to the winery's specs.

The result isn't big and tannic. The wines are soft and silky, and still rich and full in the mouth. Every red we tasted had that texture.

Beckstoffer: The Most Expensive Grapes in Napa

Most of Lithology's top wines come from vineyards owned by Andy Beckstoffer, Napa's best-known grower. Lithology doesn't own these vineyards. It buys the fruit, and pays dearly for it. Beckstoffer pioneered tying the price of his grapes to the price of the finished bottle, and Spencer says a wine that carries a Beckstoffer vineyard name has to sell above a set price.

Spencer puts the fruit at about $55,000 to $60,000 a ton, for Cabernet Franc as well as Cabernet. That math is why Lithology is stopping its single-vineyard Cabernet Francs: the 2022 To Kalon Cabernet Franc we tasted is the last one, and so is the Dr. Crane Cabernet Franc. Every ton of Cabernet Franc was a ton of Cabernet they didn't get. Instead there's a small 2023 Napa Valley Cabernet Franc, about 50 cases.

Beckstoffer To Kalon, Oakville

If Napa had grand cru vineyards, To Kalon would be the first one named. (Napa has no official grand cru system; this is reputation, not law.) H.W. Crabb planted it in 1868. The name is Greek, roughly "the beautiful" or "the highest good." Beckstoffer bought his 89-acre portion from Beaulieu in 1993 and replanted it the next year. He sells fruit to a short list of top producers. The Robert Mondavi Winery owns the largest share of the original vineyard.

Beckstoffer Dr. Crane, St. Helena

Dr. George Belden Crane planted this vineyard in 1858, inside what's now the town of St. Helena. In the 1920s the site was St. Helena's Chinatown. Beckstoffer bought it in 1997 and replanted the next year. It's 25 acres of gravelly loam just west of Highway 29, protected by a conservation easement since 2018. Lithology first bottled it in 2016.

Beckstoffer Las Piedras, St. Helena

Las Piedras means "the stones," a natural fit for this winery. Beckstoffer bought the vineyard in 1983. It's 25 acres, and Lithology has bottled it since 2015.

What We Tasted

Spencer poured a white, a Cabernet Franc and three single-vineyard Cabernets, most of them from 2022. The 2023s are just starting to go out, to wine club members first.

2023 Lithology Ritchie Vineyard Chardonnay, Russian River Valley

Matt grew up drinking Burgundy and Bordeaux, and this is his little baby Burgundy, as Spencer put it. It's a Sonoma wine from a Napa winery: the fruit comes from Kent Ritchie's vineyard in Forestville, one of California's most famous Chardonnay sites, with vines dating back to 1972. Ritchie is an old-school farmer. When a vine gets sick, he pulls it out and plants a new one, so Lithology's rows hold vines that are 30, 10 and 5 years old side by side.

It's barrel fermented, goes through malolactic, and sees about 25 to 30 percent new oak. The oak stays in the background. It's fresh and bright, with lemon zest, citrus and real acidity. Put it in a lineup of white Burgundy and I think you'd have a hard time picking it out. That was exactly Matt's goal. There are only about 120 cases, and Spencer says they're getting a few more rows next year.

2022 Lithology Beckstoffer To Kalon Cabernet Franc

Mostly Cabernet Franc, with a little Cabernet Sauvignon, and none of the green, bell-pepper notes that turn a lot of people off Cabernet Franc. It's pretty and silky. I told Spencer I was hard pressed to think of a better Cabernet Franc from Napa. That was a stunning one. It's also the last vintage of it, and it's sold by the winery, not by us.

2022 Lithology Beckstoffer Las Piedras, Dr. Crane and To Kalon Cabernets

Then the three Beckstoffer Cabernets, side by side. 2022 was a brutal year in Napa, with a historic heat wave in September, and it isn't considered one of the great vintages. Spencer says Matt declassified a lot of wine that year and sold it off in bulk, so only the best barrels made it into these bottles.

It shows. These are some of the best 2022s I've tasted, period. All three have Matt's silky texture. And that's the point: great winemakers make great wines even in vintages that aren't considered great. Matt Sands did exactly that with these three wines, and with all of his 2022s.

The critics agree. Lithology's 2022 Dr. Crane drew 97 points from Decanter and 98 from International Wine Report. The 2021 To Kalon earned 98 from Jeb Dunnuck. The flagship Alejandro Bulgheroni Cabernet has earned perfect scores three years running: 100 points from Jeb Dunnuck for 2021, from International Wine Report for 2022, and from both The Wine Palate and International Wine Report for 2023, according to the winery.

Why Lithology Is Real Value in Napa

Here's what I want collectors to understand. Lithology is making wine at the very top level in Napa, from the same vineyards and with the same caliber of team as wineries that charge far more. And it's still priced like a secret.

• Same vineyard, less money. We carry To Kalon Cabernets from several of Napa's top names. Paul Hobbs's Beckstoffer To Kalon is $550 a bottle at Big Hammer. Schrader's To Kalon works out to about $500 a bottle and Realm's Beckstoffer To Kalon to about $400, both sold in six-packs. Lithology's To Kalon is $300, with 98 points from Jeb Dunnuck. Only Tor's comes in at a similar price.
• Cult quality without the cult price. Hundred Acre's single-vineyard Cabernets run about $750 at our store. Lithology's single vineyards are $300, and its 100-point flagship lists at $400.
• The house style for $150. The Napa Valley Cabernet is made by the same team with the same silky texture, from estate fruit plus St. Helena, Oak Knoll and Howell Mountain. It's the best way to find out what Matt Sands does before you buy a single vineyard.

Prices are Big Hammer's as of November 2026 and change with each release. Here's what we have now:

• 2021 Lithology Napa Valley Cabernet Sauvignon: the place to start.
• 2021 Lithology Beckstoffer To Kalon Cabernet Sauvignon: the famous vineyard, at a fair price.
• 2022 Lithology Beckstoffer Dr. Crane Cabernet Sauvignon: proof of what Matt did in 2022.

The Lithology Lineup and Prices

Lithology's release prices for its current wines, from the winery's own price list:

A naming tip: many shops, including ours, list the Napa Valley Cabernet with "Alejandro Bulgheroni" in the title. The flagship is a different wine, sold as the Alejandro Bulgheroni Cabernet Sauvignon. Check the full name and price before you buy.

What's Coming From Lithology

• Steltzner Vineyard Cabernet: the new 2023, about 150 cases, from the Stags Leap District.
• Napa Valley Cabernet Franc: about 50 cases of 2023, replacing the single-vineyard Cabernet Francs.
• Martha's Vineyard: Spencer says Lithology got fruit from this famous Oakville vineyard in 2025, one of only a few wineries to do so. If it makes Matt's cut, there will be a Lithology Martha's Vineyard Cabernet.
• The 2023 single vineyards: going to wine club members first, then to the trade.

The 2026 Harvest: Early and Short

We visited just as harvest wrapped up. That morning, assistant winemaker Mark Pittman had cleaned out the last two tanks.

It was a strange year. A hot March pushed the vines to flower early, then wind knocked off much of the fruit set. Lithology picked Dr. Crane on September 3, its earliest Cabernet pick ever, and was done by the end of September. The crop was down 40 to 50 percent.

Spencer wasn't worried. After three big harvests in 2023, 2024 and 2025, and with wine sales down across the industry, a small crop may not be the worst thing.

Can You Visit Lithology?

Yes, by reservation. There are no walk-ins. Tastings are at the estate, 500 Meadowood Lane in St. Helena, for groups of two to eight, and reservations are prepaid. The visit includes a ride up to the top of the estate, the view in our video, and a small food pairing. Book through lithology.wine, and ask what will be poured when you book; with wines this small, the lineup changes.

If you go, ask about the rocks on the labels, and save room for the apricot canapé.

Which Lithology Should You Buy?

• Your first Lithology: the Napa Valley Cabernet. It's the widest release and shows the silky house style for $150.
• A famous vineyard: To Kalon, the closest thing Napa has to a grand cru, for less than most To Kalons.
• St. Helena character, and the 2022 story: Dr. Crane.
• A vineyard comparison: open To Kalon and Dr. Crane side by side. Same team, same cellar; only the vineyard changes.
• The white wine drinker: the Ritchie Vineyard Chardonnay, from the winery, if you can find it.

Quick Answers: Lithology Winery

What is Lithology wine?

Lithology is a small Napa Valley winery in St. Helena, owned by Alejandro Bulgheroni. It makes single-vineyard Cabernets from Beckstoffer's To Kalon, Dr. Crane and Las Piedras vineyards and from Steltzner Vineyard, a flagship Alejandro Bulgheroni Cabernet, a Napa Valley Cabernet and Cabernet Franc, a Ritchie Vineyard Chardonnay and an estate Sauvignon Blanc.

Lithology is the study of rocks. Consulting winemaker Philippe Melka, who has a background in geology, helped choose the name, and each label carries a different rock to stand for the vineyard the wine comes from.

Who owns Lithology?

Alejandro Bulgheroni, the Argentine energy executive who founded Bodega Garzón in Uruguay. His group, Alejandro Bulgheroni Family Vineyards, owns about 15 wineries in six countries. Lithology is its only winery in Napa.

Is Lithology the old Promontory winery?

The building is. Lithology's stone winery, down the street from Meadowood in St. Helena, was the first home of Bill Harlan's Promontory and the first vintages of the Napa Valley Reserve. Bulgheroni bought it from the Harlan family in 2014. Promontory itself is a separate Harlan winery in Oakville.

Is Lithology the same as Alejandro Bulgheroni Estate?

Yes. The winery started out as Alejandro Bulgheroni Estate and was renamed Lithology. His name still appears on the flagship Alejandro Bulgheroni Cabernet, made from the best barrels each year.

Which Lithology wine is the flagship?

The Alejandro Bulgheroni Cabernet Sauvignon, a selection of the best barrels from Oakville and St. Helena, at $400 on release. It's a different wine from the Napa Valley Cabernet, which some shops also list with "Alejandro Bulgheroni" in the name.

Who makes Lithology wines?

Winemaker and general manager Matt Sands, a New Zealander who worked harvests at Screaming Eagle and Bryant Family, has made the wines since 2015. Mark Pittman is assistant winemaker, and Philippe Melka and Maayan Koschitzky consult.
