Leto Cellars was founded in 2008 by long time Napa veteran winemaker Brad Warner and his wife Lisa. Their first wine was a Chardonnay. While not owning any vineyards, they work with small family growers in select locations – mostly within Napa Valley.
Brad was born in Sebastopol in neighboring Sonoma County and was raised on the Mendocino coastline of Northern California. He wasn’t really sure what career path interested him after graduating from high school. Part of his extended family owned Warner’s Creamery (known for ice cream, operating in the 1950s and 1960s) at 1910 Mendocino Avenue in Santa Rosa; the site is now home of O’Reilly Auto Parts. They introduced Brad to a couple living in St. Helena at the time who were friends of the family. This couple leased (from Chevron) and ran a gas station in St. Helena. They were looking for someone to manage this gas station and offered the position to Brad.
After two weeks Brad realized running a gas station wasn’t something he was interested in doing for very long – fortuitously, an Italian neighbor, Alfredo Santi who had worked at Charles Krug since the late 1940s invited Brad to come with him to the cellar. This was 1967. Brad’s first winery job in Napa was at Charles Krug cleaning the tops of tanks. As Brad jokes, “I started at the top in the wine business”. It is now in the 2020s and there are very few winemakers still active in Napa Valley who assisted with winemaking in the 1960s.
While working at Charles Krug he was still helping manage the gas station. Vintners would stop by to fill up their tanks; they were the who’s who of Napa Valley at the time – including Louis Martini, Joe Heitz and Robert Mondavi who had just opened his brand-new winery in Oakville. Brad had met Mondavi prior while working at Charles Krug. One day Robert Mondavi stopped into the gas station and invited Brad to come see his new winery.
That first visit turned into a job as a cellar foreman position at Robert Mondavi Winery. For some time, Brad was working 7 days a week for both Mondavi brothers – dividing his time between Charles Krug and Robert Mondavi wineries. He is certainly one of the only ones if not the only one who held down two jobs with the Mondavi brothers.
The invite from Robert to visit his winery turned into a nearly 30-year career working at Mondavi until 1999 working his way up to Mondavi’s Vice President of Production, and then Director of Property & Facilities. It was also a career that afforded him visits to other wine regions including Bordeaux and Burgundy in France, further broadening his winemaking perspective.
Brad became winemaker for Sawyer Cellars in the late 1990s – a role he continues with today.
And of interesting note; Brad’s career at the gas station has come full circle. In 1997 he purchased the old gas station that provided him his first job in the Napa Valley, and he continues to own it today.
After many years of working for Robert Mondavi Brad noticed new wineries would often borrow wine making equipment. In 1991 he started his own company, Rutherford Equipment Rental which focuses on renting a variety of wine making equipment to other wineries and vintners. The name of the company is in homage to Rutherford, where was living at the time. His first equipment was a pressure washer for cleaning winemaking equipment and several tanks. As demand grew, he would purchase more equipment.
His early marketing efforts were by both word of mouth and through someone he hired to physically drop off flyers advertising his services to area wineries. While referrals should still be a part of any healthy business, how times have changed in regard to dropping off flyers. We remember the flyer marketing efforts when we ran a small Internet Service Provider back in the 1990s and used to made trips up and down the state tacking flyers onto bulletin boards at various colleges and shopping centers.
Along with equipment Brad and his team also provide consulting advice when needed – especially relating to wine filtering equipment. Much more recently he started another business called Transition Equipment whose primary services including buying and selling used wine making equipment. And he operates Warner Winery Consulting; with more than 50 years making wine in Napa Valley, his perspective and expertise covers all aspects of cellar needs. Lisa is an integral part of the operations of this business.
One of his products is quite interesting – the Airocide air purifier was developed by NASA essentially to provide a germ-free environment in the space shuttle. It has no filter and has proven itself an excellent solution for eliminating airborne mold spores – especially helpful in environments containing higher humidity. While working in the cellar at Sawyer Cellars Brad noticed a proliferation of mold in various parts of the winery. After implementing this product, he noticed within two weeks nearly all the mold had been eliminated.
And Lisa is very much involved helping run Leto Cellars. She loves the freedom that not owning vineyards brings to the business – “the freedom to play and experiment” as she says, “and then if the wine is beautiful, we will bring it to the customers.”
She grew up in Petaluma (neighboring Sonoma County) in a family where wine was not part of daily meals. Her interest in wine was not until much later in life. Her appreciation for food came first; initially from watching food shows on public television. She loves to cook and says, “I love the power of food – not only it’s obvious characteristics but it can create an instant community with people coming together to enjoy a meal and the conversation it brings.” Noticing her interest in food, her father said something to her one day like “perhaps you should check out this wine industry thing.” So, she did.
Like Brad, she applied for a secretarial position and was accepted at Robert Mondavi Winery – her position involved two duties: typing purchase orders on typewriters and clearing cork orders through customs. While not being directly involved in wine making or hospitality, she always felt like Robert Mondavi Winery made sure all their employees, no matter what their roles were felt as if they were an integral part of the wine industry.
Her ‘ah moment’ regarding wine involved pairing a Robert Mondavi Fume Blanc with food. She realized how the two could complement each other. And it was at Mondavi that she also met Brad.
Choosing names for wineries can sometimes be difficult based on already existing winery names. In Greek Leto means “hidden from view” or “the hidden one” – this ties in well with their story in several ways. Their winery is in an industrial park and is certainly hidden from view – away from all the vineyards and wineries up valley. In addition, the single vineyards they work with are often under the radar. And they thought about it in another way after Brad bumped into Tim Mondavi at a Premier Napa Valley auction event in early 2016. Tim mentioned to Brad that his career has always been helping other vintners – defining more of a background role then a visible role. And not related, but Leto means summer in Russian.
During harvest, Brad picks the grapes by taste, not chemistry, but always validates his picking decisions by checking the numbers of both natural acidity and pH.
Select Wines
Whites
Sauvignon Blanc
The 2024 Leto Cellars Sauvignon Blanc, Sonoma County was fermented in stainless steel. This wine is medium straw in color; the bouquet smells like spring florals including honeysuckle and citrus blossom. Its typicity is well represented on the bouquet and is not bled out by over ripeness. Additional notes include guava, kiwi, lime zest and lemongrass. This wine tastes like not fully ripe golden delicious apples, under ripe pineapple, guava, kiwi, gooseberry, limeade, honeydew melon and passion fruit. Zippy across the palate like a race car driver in full control of the track, the acidity keeps this wine fresh and bright. The mouth feel is lightly creamy but is buoyed high by the acidity. Never tart or bracing, this expression is a lovely and balanced integration of flavor, acidity and texture. Its personality screams for seafood; perhaps enjoy with BBQ shrimp, raw oysters or lightly seared scallops. Or even a spicy Pad Thai.
In 2022 the grower for their Sauvignon Blanc called and informed them because of the drought, they had extremely reduced yields and would not be able to sell them grapes that year. So Lisa and Brad began searching for another vineyard source; they discovered Notre Vu Vineyard, a 710 acre estate near Windsor in neighboring Sonoma County. They continue to work with this vineyard for their Sauvignon Blanc.
The 2023 Leto Cellars Sauvignon Blanc Sonoma County is was fermented in stainless-steel medium gold in color; immediately upon nosing this wine, the first aromatic hit we wrote was pineapple, but there is plenty more going on here including aromas of grapefruit, granadilla, orange blossom, ripe honeydew melon, tropical guava, lychee, white nectarine and as the wine evolves in the glass, prominent notes of vanilla and caramel The bouquet is saddled more towards tropical scents offered from warmer locations but with some herbal essences inherently expressed by this variety. Bright, balanced and beautiful, the palate offers flavors of pineapple, honey crisp apple, peaches, yellow nectarines and crushed vitamins. This wine features a long, flavorful and fleshy filled finish. It drinks very well by itself.
The 2019 Leto Cellars Sauvignon Blanc Napa Valley is medium straw color in the glass; the bouquet sports sweet/sour aromatics including of pineapple, citrus blossom, freshly cut grass, gooseberry, kiwi and a lemon zest. On the palate this wine is creamy and rounded in texture with a persistent brightness and flavor filled finish lingering with notes of lemon/lime, peach and nectarine. This wine was sourced from a hillside vineyard in Pope Valley. After fermentation, the wine was aged in stainless steel tanks; only 115 cases were produced. This bottling would pair extremely well, chilled, while sitting curbside on the streets of Bangkok eating a spicy chicken foot salad.
Chardonnay
The 2013 Leto Cellars Chardonnay was barrel fermented using indigenous yeasts and allowed to undergo a measured 50% secondary fermentation, striking a perfect chord between creamy texture and vibrant energy. The grapes are from a historic, dry-farmed vineyard in St. Helena that Leto Cellars has championed since their inaugural vintage. These old vines, originally planted in 1973, produce naturally low yields that result in a wine of concentration and character. On the nose, the bouquet is immediately inviting, offering rich aromatics. Notes of white pineapple and baked golden apple are interlaced with warm baking spices and a distinct, stony minerality. The palate is harmoniously balanced and elegantly rounded, avoiding any heavy or cloying viscosity. This inherent richness of fruit is brightened by a backbone of crisp acidity, leading to a remarkably clean finish that lingers long after the final sip.
Reds
Merlot
The 2021 Leto Cellars Merlot, Mt Veeder Napa Valley is 100% varietal and was made entirely from free-run juice. This wine is deep ruby in color; the bouquet is dark and savory including aromas of pipe tobacco, menthol, old cedar box which hasn’t been opened in a long time, spiced plums, red licorice, cherry and a hint of dried bay leaf. Both red and dark fruited on the palate, this wine offers flavors of red cherry, currant, cranberry and plum. It shows extremely youthful at the time of our tasting, less than 3 years post vintage, especially in terms of its texture. The grainy and granular tannins fully coat the palate lingering with a dusty and drying character and a note of dried tobacco leaf, both of which ultimately outrun the fruit on the finish. This is a serious mountain Merlot sure to please Cabernet Sauvignon enthusiasts looking for a bit ‘more’ from their Merlots.
Cabernet Sauvignon
The 2021 Leto Cellars Cabernet Sauvignon, Napa Valley is inky dark, deep ruby and opaque; the word shy is not in this wine’s aromatic vocabulary. Expressive out of the gate, its sweetly fruited scents include blackberry pie, boysenberry jam, dark plum and raspberry with additional layers including of dried tobacco leaf, lavender, cocoa powder and red chili spice. This wine has a certain voluptuousness but also an inherent character that makes you want to delve a little bit deeper into its personality. Bright, balanced and filled with flavor, this wine tastes like Santa Rosa plum, boysenberry, dark mulberry, dark cherry and blackberry. The fruit dominates, but there is also a pleasing complement from the oak; its non-fruited flavors include smoked cedar, dried sage, dried tobacco leaf and toasted oak (but never oaky). The tannins are lightly gravelly, broadly distributed across the palate and linger in parallel with the fruit on the finish. Medium bodied. A steak wine? Yes. Perhaps a well-marbled Wagyu, this wine and a BBQ for best results.
The 2019 Leto Cellars Cabernet Sauvignon Napa Valley is deep ruby and nearly opaque; the ripe and sweetly fruited bouquet offers aromas of dried black figs, black cherry, boysenberry, dark Pakistani mulberry, cassis, and assorted baking spices including cinnamon and cardamom. There are no woodsy spices contributed from its oak aging, in part attributed to Warner’s judicious use of new oak barrels. The palate echoes the bouquet to some extent and reveals flavors of plum, dark cherry, dark licorice, chocolate, boysenberry jam and blackberry preserves. We love the texture on this wine, featuring a noticeable density of tannins but with a polished and chalky character.
The 2016 Leto Cellars Cabernet Sauvignon, Exceptional Selection Napa Valley is deep ruby in color. A straight up aromatic brooder upon opening, this wine smells like damp potting soil, dried mushrooms, pipe tobacco, sage and tar. Dark, layered and needing time to evolve, some of these initial scents will dissipate with time. Additional scents include dark chocolate, spicy plum skin, soy sauce, mocha and toast. Only in wine do all these scents work together harmoniously; by this we mean putting all these together as flavors in the kitchen might be a hard fail. This is a distinctive bouquet. On the palate, there are flavors of dark fruits, their fresh characteristics softened by time in the bottle. These include dried cherries, boysenberry, blackberry and dark raspberry, accompanied by chocolate, tobacco and a light kiss of coffee creeping into the finish. The tannins are very much still present and linger with a lightly grainy and gravelly textural feel. And a fully coating dusty grip. And lots of persistent fruit. This palate is the definition of layering and complexities; time in the bottle has been kind to this beauty. For reference we needled and nosed this 9 years post vintage. This wine was aged for 21 months in French oak barrels and then spent an extended aging (6 years) in bottle prior to release.
The 2012 Leto Cellars Cabernet Sauvignon is 100% varietal sourced from the same vineyard in St. Helena as their Chardonnay, also from dry farmed vines. This is the inaugural vintage of Leto Cellars Cabernet Sauvignon. Ruby red in the glass, initially it shows an earthy/slightly dusty component to the bouquet – it is dark and brooding with hints of toasted cedar. The wine is superbly balanced with a palate that is all about the fruit rather than the oak. The balanced slightly dusty tannins linger along with a red cherry, red currant tartness on the finish.
Two other interesting wines that Leto Cellars has produced in the past, including a Pinot Noir from Mt. Veeder growing at an elevation of 1850 feet close to where Brad and Lisa live and a Riesling sourced from old vines in Rutherford; these were not yet finished wines during our first visit to the cellar in mid 2016.

Tastings are for wine enthusiasts; this is a rare opportunity to sit down with a long-time winemaker and taste through the wines in a very relaxed setting. Total production is about 1,500 cases annually. They mostly sell direct to consumer but have one client in China, a small wine club in Japan and the wine is available at select restaurants and wine shops in Los Angeles and a few retail outlets in Napa Valley including at Wine Country Connection in Yountville. They do not maintain a wine club, primarily because they do not want to be on a schedule of having to release wines at a certain time. Rather, they evaluate each wine on its own merit and will release them when they feel they are ready.

Thank you for such a kind review. I just now saw this! We’ll let you know when we release the Pinot Noir – I can’t wait.
Lisa – absolutely 🙂 I’ll see if I can bring some clients by at some point as well.
Lisa; Thank you for sending me a sample of your 2016 Rutherford Cabernet Sauvignon… Is this a pure Cab Sauvignon,,, or a blend ?
Also,,, will you have any 2016 or 2017 Chardonnay ( Burgundian Style ) available now,,, or in the next 3 -to- 6 months.
Please give my hello to Brad,,, I remember renting his equipment the I was “St. Helena Winery”,,, before retiring,,, and now – starting all over again
Peter – nice to hear from you, it has been a long time since we met at St. Helena Winery. My good friend Emil also remembers renting from Brad.
I’ve since been back several times to St. Helena Winery since you and I met, and updated my review since the ownership change. I also met with Kristian a while back. I knew you had started over – pretty impressive. Time goes by even quicker when you get older!
I stopped by Granite Bay a few years back and walked over to your tasting room. Nice to also visit Sam Molhotra’s wine shop/Work Vineyard Napa Valley. Work was the 1,000th Napa Valley winery/brand I visited with. Hope things are well in the foothills. ~ Dave
