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.

The winery’s objectives are: To channel the fruit of ancient vines into powerful, elegant, and distinctly Californian wines. To spread the gospel of Syrah in California by sourcing fruit from great terroirs throughout the North Coast. To proclaim the greatness of Sonoma Valley Cabernet Sauvignon by sparing no expense on wines of uniqueness and personality. To reclaim rose’ from the excesses of saignee and focus on precision, delicacy, aromatics, and food friendliness. To make fascinating and quixotic white wines from unique sites and interesting varietals. To dream big but keep production low! 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

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.
  • Bedrock 2014 Old Vine Zinfandel, California
    Rating: 91 (2/15/2016)

    The 2014 Old Vine Zinfandel is deep, rich and luscious, with plenty of up-front fruit and tons of appeal. More of a field blend than a true Zinfandel, the 2014 is soft and forward, with expressive red-fleshed fruit, bright acidity and terrific overall balance. The Old Vine is 77% Zinfandel and a generous 23% mixed blacks. Best of all, the Old Vine Zinfandel is a fabulous value.

    Plush and jammy, but well-focused, with gobs of fruit and flavors of wild berry, licorice and smoky pepper. Drink now through 2026. 5,000 cases made.
  • Bedrock 2014 Heritage White, Compagni Portis Vineyard, Sonoma Valley
    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 'The Bedrock Heritage' Sonoma Valley

    Rating: 96 (10/28/2016)

    Possibly the flagship wine is the 2015 Proprietary Red The Bedrock Heritage. This ancient vineyard is planted with 27 different varieties, so I won’t even begin to list them, as that is a book in itself. This is Rhône Valley-like, with notes of Mediterranean herbs, blackberries, blueberries, loamy soil notes, incense, creosote, steak tartare and pepper followed by a wine of great intensity – built like a skyscraper, with layers of fruit and extraction. It is a sensational effort, super-complex, and best drunk over the next decade.
