Phil Coturri's personal winery, California's most influential organic viticulturist, who has farmed Kamen, Amapola Creek, and Moon Mountain for 40+ years. The tasting house is a 120-year-old Sonoma Plaza farmhouse with antique theater seats, a vinyl turntable, and original Stanley Mouse Grateful Dead art. Single-vineyard organic wines Phil farms himself.

















Named for an address in the hills high above Sonoma, Winery Sixteen 600 has mountain roots: Sam Coturri was raised from the age of six at 16600, in the Moon Mountain District. He joined the family business in the spring of 2011 to build the winery, the year its first vintage was released with Stanley Mouse label art. The focused Moon Mountain District tasting pours wines from that rugged corner of Sonoma, where volcanic soils shape their character, while brother Max, who studied art at Chico State, brings that eye to sculpting mountainside vineyards.
Cabernet Sauvignon, Sonoma Valley: a single-vineyard, certified-organic Cabernet honoring the family's Sonoma heritage.
Severson Vineyard Zinfandel, Sonoma Valley: classic old-school Sonoma Zin from a rare valley-floor site; brambly red fruit, white pepper and baking spice.
Petite Sirah: a dark, structured small-lot bottling from organically farmed hillside fruit.
Field Blend: a co-fermented red led by Zinfandel with Grenache, Petite Sirah and Alicante Bouschet; a nod to Sonoma's old mixed-black vineyards.
Founded in 2007 by pioneering organic grower Phil Coturri with his wife Arden Kremer and sons Max and Sam, Winery Sixteen 600 makes small-lot, single-vineyard wines exclusively from the certified-organic vineyards Coturri farms: reds rooted in Sonoma, alongside Rhône varietals and Grenache.
Founded in 2007 by Phil Coturri (California's most influential organic viticulturist, farming vineyards for producers like Kamen, Amapola Creek, and Moon Mountain Vineyard for over 40 years) along with his wife Arden and sons Max and Sam. The tasting house is a 120-year-old farmhouse just one block from the Sonoma Plaza, set up with antique theater seats, a vinyl turntable with eclectic selections, and Stanley Mouse artwork (the designer of Grateful Dead album covers). Tastings are deliberately comparative, wines poured side by side, focused on single-vineyard bottlings sourced exclusively from certified organic vineyards that Phil farms personally. The lineup covers Rhône varietals (Grenache, Syrah, Viognier), Zinfandel, and Cabernet Sauvignon. One of Sonoma's most personality-driven tasting experiences.

Winery Sixteen 600 is the label of Sonoma's Coturri family, founded in 2007 by famed organic and biodynamic viticulturist Phil Coturri with his wife Arden Kremer and sons Max and Sam, with Sam Coturri leading the winemaking and the winery's Sonoma tasting house. After more than four decades pioneering organic viticulture in Sonoma Valley, Phil farms the certified-organic vineyards through his Enterprise Vineyards company, and the winery bottles small-batch, single-vineyard wines that reflect that vineyard-first philosophy: Grenache and other Rhône varieties, field blends, and the Cabernet and Zinfandel that honor the family's Sonoma heritage. The labels feature artwork by family friend Stanley Mouse.

Arden Kremer co-founded Winery Sixteen 600 in 2007 alongside her husband, legendary organic viticulturist Phil Coturri, and their sons Max and Sam. The family winery draws exclusively on certified-organic, single-vineyard fruit from the Sonoma Valley hillsides Phil farms through Enterprise Vineyards. Beyond the cellar, Arden is an accomplished olive-oil specialist and producer, crafting estate olive oil from the same land. A steady force in one of Sonoma’s most beloved farming families, she helped turn a deep-rooted commitment to soil health and place into a label known for Grenache, Rhône varieties, field blends, and heritage Cabernet and Zinfandel.
