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

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 2014 Heritage White, Compagni Portis Vineyard, Sonoma Valley
    Rating: 93 (2/15/2016)

    The 2014 Compagni Portis Heritage Wine is simply stunning. Gewürztraminer takes center stage in this white field blend from vines first planted in 1954. Tropical fruit, mango, lychee, mint, orange blossom and lemon confit are laced together in a striking, mid-weight wine loaded with personality. Even with its overt richness, the 2014 retains gorgeous freshness and salinity. The Compagni Portis is a blend of Gewürztraminer, Trousseau Gris, Roter Veltliner, Riesling and Chardonnay.

    Rating: 91 (8/1/2016)

    A field blend of Gewurztraminer, Trousseau Gris, Riesling, Burger and a few vines that remain unidentified, the historic Compagni Portis Vineyard was founded in 1954. Dry-farmed and organic, it yields less than 15hl/ha. The resulting wine is unique: smooth and unctuous with a spine of acidity. Stone fruits and almonds show up among its flavors.
  • Bedrock 2015 'Cuvee Karatas' Bordeaux Blanc, Sonoma Valley
    The Wine Advocate
    Rating: 94 (10/28/2016)

    The 2015 Cuvée Karatas Semillon/Sauvignon Blanc is a blend of Sauvignon Blanc and Semillon, the latter from a parcel of Semillon planted in the 1880s in the Monte Rosso Vineyard. Morgan Peterson says it is “one-of-a-kind stuff” and there is no reason to doubt him. This is more of an over-the-top flamboyant, rather amazing wine with notes of orange marmalade, honeydew melon, jam, quince, white currants and flowers. There was an almost unctuous quality to the texture and super-concentration from these two varieties. Most of this is from dry-farmed vineyards and the honeyed, low-yields that were present in 2015 are translated into this wonderfully fresh, incredible wine that almost behaves like one of the great Ygrecs from Chateau d’Yquem. Drink it over the next 5-7 years, although I wouldn’t be surprised to see it last longer.
  • Bedrock 2015 'Drummond's Cuvee' Petite Sirah, California
    Rating: 90 (3/1/2017)

    Inky blue and purplish fruit, spice, licorice and chocolate are all pushed forward in the 2015 Petite Sirah Drummond's Cuvée. This is an especially inky, unctuous Petite with good overall balance and potential, if not quite the pedigree of the finest wines in this range. The Drummond's Cuvée is a blend of fruit from Eaglepoint Ranch, in Mendocino, and Palisades, the well-known site in Napa Valley.

    Rating: 92 (3/1/2017)

    Bedrock's 2015 Cuvée Karatas, is a gorgeous Sauvignon/Semillon blend. Lemon confit, white flowers and orchard fruit are beautifully delineated, but it is the wine's textural balance and overall poise that truly stand out.
  • Bedrock 2015 'Drummond's Cuvee' Petite Sirah, California
    The Wine Advocate
    Rating: (94-96) (10/28/2016)

    A barrel sample of the 2015 Petite Sirah Drummond’s Cuvée comes primarily from Mendocino’s Eaglepoint Ranch, which used to make up Sean Thackrey’s Sirius Syrah. This massive, rich, concentrated Petite Sirah is a 50-year wine. Black as a moonless night, it displays notes of graphite, incense, camphor, blueberry and blackberry liqueur. It is still in barrel, but it’s a monster. More on this once it’s in bottle next year.
  • Bedrock 2016 Old Vine Zinfandel, California
    Rating: 89 (1/16/2018)

    Bedrock's 2016 Old Vine Zinfandel is soft, fruity and forward, all qualities that make it an excellent choice for drinking now and over the next handful of years. There is good depth to the tobacco, cedar and cherry flavors. In many vintages, the Old Vine is an overachiever, but in 2016 it shows more like a wine at this price point should. Even so, it is absolutely delicious. This is an especially floral, restrained style for Bedrock. The 2016 is 88% Zinfandel and 12% mixed blacks from a variety of sites.
  • Bedrock 2017 'Ode to LuLu' Old Vine Rose, California
    Rating: 91 (6/14/2018)

    Expressive scents of fresh red berries, orange pith, pungent flowers and chalky minerals show excellent focus and lift. Fine-grained and nervy in the mouth, offering zesty red currant, strawberry and blood orange flavors and a spicy jolt of white pepper on the back half. The floral note sneaks back in steadily on a silky, persistent, mineral-driven finish.

    Medium to deep garnet-purple colored, the 2016 Zinfandel Old Vine is scented of black and blue fruit preserves, prunes, nuts, earth and spice cake with chocolate box notions. The palate is full-bodied with loads of freshness and soft and juicy in the mouth, finishing spicy.

    Made from 75% Mourvèdre and 25% Grenache, the 2017 Ode to Lulu Old Vine Rosé is very pale-salmon pink in color with delicate Bing cherries, raspberry leaves and red currants scents with hints of red apples and white pepper. The palate is medium-bodied with lovely spicy sparks throughout the red berries flavors, with great freshness and a peppery finish.
