Amy Prosenjak Leads A to Z Wineworks to Oregon Wine Dominance

Amy Prosenjak, currently the 53-year-old president and CEO of A to Z Wineworks LLC, has become a significant figure in the Oregon wine industry, leading brands that collectively represent approximately one in every four bottles of Oregon-origin wine sold in U.S. multi-outlet retail. This market share is measured by Circana data, which encompasses sales in grocery stores, mass merchandisers, club stores, and drugstores, though it excludes sales from restaurants, tasting rooms, and most independent wine shops. Prosenjak's journey into the wine business began unexpectedly in her early thirties. At the time, she was managing inventory for a billion-dollar furniture company in Ohio. Her husband's suggestion to pursue a career in wine tourism, an area they both enjoyed, prompted her to explore opportunities. Using WineJobs.com, she discovered that A to Z Wineworks, a then-small Oregon winery co-owned by two couples and in the process of acquiring Rex Hill, was seeking a chief financial officer. Prosenjak submitted her resume on a whim. Bill Hatcher, one of A to Z's founders and the CEO at the time, contacted her to assess her financial acumen. When Prosenjak highlighted her extensive experience in inventory management for a major corporation, Hatcher expressed confidence in his ability to teach her the wine business, a promise he fulfilled. This career pivot involved Prosenjak selling her home and relocating across the country, embarking on what she describes as a "wonderful and wild 20-year ride." Under her leadership, A to Z Wineworks now oversees not only its namesake brand but also the Erath and Rex Hill brands. The company's production has seen adjustments in recent years; following a period of expansion, overall production across its brands decreased by approximately 32% in 2025, reaching 550,000 9-liter cases. A to Z Wineworks anticipates maintaining production levels around this figure for 2026. Prosenjak has articulated a consumer-centric strategy, stating, "We’re going to follow the consumer. If we need to be a slightly smaller company, we will do that because we’re going to stay true to our winemaking values. But we want to stay profit."
