Mount Pisgah, Polk County, Oregon AVA

Mount Pisgah, Polk County received official TTB approval on June 3, 2022, with an effective date of July 5, 2022. Brad Ford of Illahe Vineyards initiated the petition approximately five years before approval, reflecting the long-standing recognition among local growers that this area warranted its own distinct identity. Viticulture in the area traces back to 1981-1982, when Freedom Hill Vineyard first established plantings. The AVA's unusually long name was required to distinguish it from another Mount Pisgah in Lane County, Oregon, and additional Mount Pisgahs elsewhere in the United States. The petition received unanimous support during TTB review, with 19 comments from the local industry.

• TTB petition initiated by Brad Ford of Illahe Vineyards roughly five years before approval
• Freedom Hill Vineyard established the first vineyards in the area in 1981-1982
• Effective date of July 5, 2022; Oregon's 23rd AVA
• Full county and state designation required to avoid consumer confusion with other Mount Pisgahs in the U.S.

The mountain at the heart of this AVA formed approximately 65 million years ago as a sea floor volcano, later covered by marine sediment. This origin gives the AVA its defining characteristic: soils composed of marine sedimentary material, including sandstone and siltstone, overlying Siletz River volcanics. These are the oldest rock formations in the Willamette Valley. The Siletz soil series found here is particularly well-suited to Pinot Noir and Chardonnay production and is not replicated in comparable surrounding regions, forming the primary basis for the AVA's distinct boundary.

• Mountain formed 65 million years ago as a sea floor volcano
• Siletz River volcanics represent the oldest rock formations in the Willamette Valley
• Shallow soils rich in marine sediment, sandstone, and siltstone
• Siletz soil series is uniquely suited to Pinot Noir and Chardonnay and not found in similar nearby areas

Mount Pisgah, Polk County benefits from a combination of climatic influences that distinguish it from the broader Willamette Valley. The warmth of the nearby Willamette River moderates temperatures, while Laurel Mountain to the west creates a rain shadow effect. Van Duzer winds provide a mild cooling influence without the vine stress associated with high-wind areas. Average wind speed of 2.3 mph is notably low, reducing damage risk. Elevations between 260-835 feet, with grape production concentrated between 260-750 feet, and south-facing slopes provide good sun exposure and frost protection. The average growing degree day total of 2,543 places the AVA on the cooler end of the Willamette Valley spectrum.

• Rain shadow from Laurel Mountain reduces excess moisture
• Willamette River proximity provides warmth; Van Duzer winds offer mild cooling
• Average GDD of 2,543; cooler than much of the surrounding Willamette Valley
• South-facing slopes advantage over north-facing surrounding terrain; elevation reduces frost risk
