Bedrock Wine Co. was founded in 2007 by Morgan Twain-Peterson in a 550 square-foot, former chicken coop with ceilings eight feet high and no fermentation space. After six years of Bedrock being a one-man-show, Morgan was able to talk his best friend, Chris Cottrell, into moving to California from New York to join him. They now happily have a little more space to move around in but share the same objectives that guided the winery at the start.

Bedrock Wine Co. is fundamentally about making wines that are hopefully a soulful expression of a vineyard and a year. Too often though, the critical link that binds a site to the winery is forgotten- the grower. It has been said a thousand times. It does not make it any less true. Great wine is made in the field. Please look through the constellation of viticulture riches that allows Bedrock Wine Co. to craft its diverse range of wines. Also, learn more about each grower.

About Morgan Twain-Peterson: Morgan Twain-Peterson was born at home in Sonoma, Ca. On January 6th, 1981 to Joel Peterson and Kate Twain. Raised at his father’s Ravenswood Winery, Morgan was exposed to wine and wine tasting at an early age. In David Darlington’s Angel’s Visits, it is noted that, “Morgan, at the age of five, could distinguish between Merlot and Zinfandel.” Morgan began making small lots of Pinot Noir at 5 from fruit given to him by the Sangiacomo family. Motivated by the best wines of Domaine Dujac, he began experimenting with whole cluster fermentation, different types of French oak, and various ripeness points. Vino Bambino Pinot Noir, as the wine came to be known, was made from 1986 to 2001 and has been featured on the wine lists of Craft, Gramercy Tavern, Blue Hill (which featured the original 1986), Delmonico’s, Aureole, and Mesa Grill.

While doing undergraduate work at Vassar (whose founder was a brewer of all things), and graduate work at Columbia University, Morgan worked as a wine buyer and salesperson for Arlington Wines and Liquors in Poughkeepsie, and Chelsea Wine Vault and Pet Wines in Manhattan.

Morgan returned home to Sonoma in 2005 to work harvest at Ravenswood. From there he spent time as a visiting winemaker at Hardy’s Tintara in McLaren Vale (where he also spent a few highly educational days with Drew and Rae Noon at Noon Winery), and in the fall of 2006 was a visiting winemaker at Chateau Lynch-Bages in Pauillac. When not working for Bedrock Wine Co., Morgan is a manager of his family’s Bedrock Vineyards in Sonoma Valley, and is a member of Sunbreak Vineyard Services L.L.C, a vineyard management company run by Diane Kenworthy and Robert Burney. He has also passed the prestigious Master of Wine exam and upon successful completion of the dissertation will become one of the (less than thirty) American Master of Wine.

When not doing wine-related things Morgan enjoys his garden of heirloom vegetables, playing piano, hiking, and cooking up good grub.

“Though I consider the winemaking at Bedrock to be very rudimentary there are several core principles that define the general philosophy. By using incredible sites and maintaining impeccable farming throughout the growing season I can do the bare minimum in the winery. By bare minimum I mean handling fruit gently, in many cases using whole-clusters, and fermenting exclusively with the microflora that comes in with the grapes or is already present in the winery. I use a little new, excellent, French oak and rack as infrequently as possible. I strongly feel that picking the moment the flavors are there is the best way to express site. Thus, I tend to pick earlier than most. I have found that late picking generally occludes terroir but fruit from still vigorous vines brings clarity to site. I generally eschew sorting except in “worst-case scenario” situations. I feel that bringing in the entire range of fruit from a given site results in the truest expression of site with a broader patina of flavors. Though I have the great opportunity to make a wonderful range of wines these rules tend to govern my decision-making in almost all situations.” - Morgan Twain-Peterson

Bedrock named Winery of the Year 2020 by Antonio Galloni for Vinous.

Voted #10 on Wine Spectator's Top 100 Wines of 2018

Vinous 1/2018
"Readers are going to find a number of fabulous choices among these new releases from Morgan Peterson and Chris Cottrell at Bedrock. The Russian River heritage wines in particular – Carlisle, Papera and Dolinsek – are especially brilliant, echoing a theme of sublime finesse I saw in many Russian River 2016s. Then there are the vineyard-designated Syrahs, the Montecillo Cabernet and a handful of other compelling wines. If that sounds like a long shopping list, well, it is."

Vinous 3/2017
"This is a remarkable set of wines from Morgan Peterson and Chris Cottrell at Bedrock. The 2015 Zinfandel and Zinfandel-based blends are outrageously beautiful. My impression is that the fruit is being picked a bit earlier than in the past, as the wines have more brightness and freshness than was once the norm, and yet they also have plenty of depth that has been such a signature here since the beginning. Cottrell attributes the increased ability to pick earlier to a greater emphasis on dry farming. Whatever the reason or reasons, the 2015s are tremendous."

Wine Advocate 10/2016
"Everybody should recognize the incredible speed at which Morgan Twain-Peterson has built his Bedrock Wine Co. into a world-class performer. Moreover, few people have done more to preserve and save heritage/ancient-vine vineyards than Peterson. Here is his new lineup of wines that shows his creative Midas touch for coaxing full character out of his diverse terroirs and blends. His commitment to excellence is something to admire."

Wine Advocate 10/2015
"Morgan Twain-Peterson’s 2014 harvest was the earliest in his relatively brief history of winemaking. But I suspect that 2015 was even earlier based on what was happening when I was in California. These are some of the more exciting wines from heritage sites in California, and Peterson has the right philosophy and a go-get-it attitude that is endearing and positive. All of these wines merit serious interest from readers looking for hedonistic, flavor-filled, full-throttle wines that are bursting with personality."


  • Bedrock 2018 Zinfandel, Esola Vineyard, Amador County
    Rating: 94 (4/15/2020)

    The 2018 Zinfandel Esola Vineyard, from a site in Amador County with granite sub-soils, is laced with a whole range of super-expressive floral, citrus, mint, chalk and white pepper notes that confer brightness and energy. The 2018 needs a bit of time to come together, but it is sublime.
  • Bedrock 2019 'Schmiedt Road' Zinfandel, Lodi
    Rating: 93 (1/12/2021)

    The 2019 Zinfandel Schmiedt Road is a rich, explosive wine with effusive aromatics and tons of Zinfandel character. Spice, leather, tobacco and dried flowers add lovely dimensions of nuance. Varietal Zinfandel notes are turned up in a wine endowed with terrific density as well as subtlety. The Schmiedt Road is a blend taken from Katushas’ and Kirschenmann, both sites in a district within Lodi that tends to produce more lifted wines.

    Rating: 93+ (1/12/2021)

    The 2019 Bedrock Heritage Wine is a tough wine to read today. It is quite tannic and closed, but also does not appear to be quite as powerful or heavy as it can be, which in my view is a positive. Size and weight come so naturally at Bedrock that the wines can at times be a little too much of a good thing. I hope to have a chance to taste the 2019 again in the future, as it is in no mood to show its cards today.
  • Bedrock 2019 Old Vine Zinfandel, California
    Rating: 92 (1/12/2021)

    The 2019 Zinfandel Old Vine is gorgeous. Bright acids and floral overtones perk up the red berry fruit in a Zinfandel that delivers the goods, and plenty more. Bright and beautifully layered, the 2019 hits all the right notes. Then again, it is a blend of stellar sites, including Bedrock, Nervo, Sodini, Evangelho, Katushas’, Teldeschi, Pagani Ranch and Old Hill. Because of the COVID pandemic and uncertain short-term economic outlook, the 2019 includes quite a bit of wine that in more normal times would he bottled in the vineyard designates. Stated simply: buy as much as you can.

    Bold aromas of rose petal and orange blossom open to dynamic blackberry, licorice and smoked pepper flavors, building tension toward medium-grained tannins.

    Packing in a lot of structure and personality, this Zin delivers vibrant black cherry, smoky garrigue and green peppercorn flavors that build toward broad-shouldered tannins. Drink now through 2029.

    Tightly focused and zesty, with vibrant cherry and cranberry flavors that gather in accents of jalapeño, briar patch and pepper, finishing with medium-grained tannins. Drink now through 2029.

    The 2019 Zinfandel Old Vine offers a more savory, darker fruited, spicy style and has loads of character. Blackberries, plums, cedary incense, flowers, and loamy soil all define the nose, and it has medium-bodied density and depth, ripe tannins, and outstanding length.

    Coming from a site that was originally planted in the 1850s (the vines for this release date back to the 1890s), the 2019 The Bedrock Heritage offers a medium ruby/plum color as well as a beautifully complex nose of cherries, red plums, lavender, herbes de Provence, and pepper. Quite structured and tannic, it's medium-bodied, has a rounded, layered texture, good acidity, and outstanding length. It's a beautiful, complex, elegant wine that needs 2-3 years of bottle age and should have 10-12 years of prime drinking.
