A to Z Wineworks

A to Z Wineworks was started in 2002 by four Oregon wine industry veterans: Deb Hatcher (Eyrie), Bill Hatcher (Domaine Drouhin Oregon), Sam Tannahill (Archery Summit) and Cheryl Francis (Chehalem). It was founded primarily as a négociant, and it started in the founder's kitchen. A to Z later acquired REX HILL, a winery founded in 1983 by Paul Hart and Jan Jacobsen, when it was outgrowing its custom crush space. When Amy Prosenjak joined in 2007, the winery was producing roughly 80,000 cases a year. It created a dedicated sales force in 2011 and completed its current winery complex before the 2016 harvest. By 2019 it was producing more than 350,000 cases a year, and it has produced up to 450,000 cases in some vintages. On September 7, 2022, Ste. Michelle Wine Estates acquired A to Z, the first strategic acquisition for Ste. Michelle under the ownership of private equity firm Sycamore Partners. The sale included the A to Z and REX HILL brands, inventory and the Newberg winery facility, and its terms were not disclosed. Combined with Erath, Ste. Michelle's existing Oregon winery, the purchase brought Ste. Michelle's total annual production in Oregon to approximately 700,000 cases. In December 2025 the Wyckoff family announced its purchase of Ste. Michelle's wine brands, facilities and vineyards in Washington, and Ste. Michelle continued as the sales agent for A to Z Wineworks, Erath and REX HILL.

Amy Prosenjak joined A to Z in 2007 as Chief Financial Officer and was promoted to President in 2014. Her promotion to President and Chief Executive Officer was announced in November 2019, with Bill Hatcher moving from Chief Executive Officer to Chair of the Board. At the 2022 sale, Bill Hatcher was retiring as Chairman of the Board, Deb Hatcher, Cheryl Francis and Sam Tannahill were to join Ste. Michelle as consultants, and Prosenjak was to join Ste. Michelle as President of Oregon Brands. Prosenjak is President and CEO of A to Z Wineworks LLC, which represents the A to Z, Erath and REX HILL brands and is headquartered in Newberg.

A to Z sources fruit from across Oregon and has worked with more than 100 vineyards in the state, always encouraging sustainability. The company is 100% Oregon sourced and based. The 2023 Pinot Noir is a blend of fruit from more than 15 different vineyards across Oregon, and the Pinot Gris is blended from fruit grown in over two dozen Oregon vineyards. As of 2022, the company farmed all of its estate vineyards organically and biodynamically. A to Z is based at the REX HILL property in Newberg, where it rebuilt and reinsulated the REX HILL tasting room in 2020. It has no public tasting space for A to Z and no wine club. A 15-month Artist in Residence program places an artist at the winery, where the artist also works as a paid harvest intern.

The current lineup covers Pinot Noir, Chardonnay, Pinot Gris, Riesling, The Essence, Rosé and Bubbles. The Pinot Noir is finished as a single cuvée after blending trials that follow primary and secondary fermentation. The Chardonnay is blended from numerous vineyards into a single cuvée, with lots fermented and aged separately, and the Pinot Gris components are also fermented separately. The Riesling blends fruit from young and old vines picked at multiple levels of flavor development and is made off-dry. The Rosé is made predominantly from old vine Sangiovese grown in Southern Oregon. Bubbles is a blend of Pinot Noir with some white wine, taking its color from skin contact rather than from blending red wine into white; it was launched at the company's 15th anniversary party. The Essence of Oregon Pinot Noir is blended from selected vineyard blocks, is made only in some vintages, and is a tiny portion of A to Z's production. As of 2022, the wines generally sold for $25 a bottle or less.

A to Z Wineworks became a Certified B Corporation in May 2014, which the company notes made it, at the time, the only B Corp in the wine industry. In September 2021 it signed on as an applicant to International Wineries for Climate Action (IWCA), becoming the first Oregon winery to do so; participating wineries commit to becoming Net Zero by 2050. As of 2022, A to Z maintained LIVE and Salmon-Safe certifications, had transitioned the majority of its brand volume to ultra-light 438g glass bottles, and had committed to reducing its carbon footprint by 50 percent by 2030. A to Z became a certified LIVE winery when the program began in 2008.

• Certified B Corporation: since May 2014
• IWCA: joined as an applicant in September 2021, the first Oregon winery to do so
