Sun shining over he Seiji barn and estate vineyard in the Chehalem Mountains

Technical

The vineyard began in 2018, planted to five acres of Chardonnay and 15 acres of Pinot Noir. Modeled after the Grand Cru sites of Burgundy, the east-facing rows enjoy soft morning sunlight and a favorable slope. A mix of resident soils — both Laurelwood and the volcanic Nekia — nourish the vines and impart character in the fruit. Farmed organically, the vineyard reaches an altitude of 860 feet and enjoys refreshing breezes and cool evening temperatures; prized traits in viticulture.

History of the Land

The beauty of the vistas here evoke visions of the first migrants, farmers, and settlers who almost 200 years ago braved rigors of the Oregon Trail to reach this fertile valley. People who traveled in search of farmland and new opportunities in the Pacific Northwest. The journey required incredible endurance, determination, and resilience. Qualities that have become an enduring part of American history and folklore. The Oregon Trail and the covered wagons symbolize the pioneering spirit of the American Westward Expansion. And this is the very place that they set out in covered wagons to reach and risked their lives to get to. The previous owner of the land left four wooden wagon wheels to Seiji Estate as a reminder to channel that same pioneer spirit in order to make the very best quality Willamette Valley wine.

The Vineyard

Seiji Estate is a small vineyard, allowing the growers of the grapes and the winemakers to concentrate on the details that make fine wine. The land is similar to Bourgogne grand cru vineyards. The slope of the land faces east, allowing the grapes to soak up morning sun and to continue soaking it up all day. A nice breeze flows in from the western hilltops, making the vineyard less moist and allowing for good drainage. The natural gifts of the land allow us to do organic firming. Because it’s the first time grapes have been planted here, Seiji Estate can allow land which has been sleeping for many years to shine.

Seiji Estate vineyards are located from a high of 860 feet to a low point of 730 feet in altitude which brings us good acidity. We also try not to use fertilizers to avoid losing exactly the right amount of acidity in the grapes, sacrificing higher volume. Our farming methods are made to complement the gifts of our terroir in order to produce the highest quality wine.

On a clear day the view from our planned tasting room includes Mt. Hood, Mt. St Helens, Mt. Adams, and Mt. Rainer. Humbling, magnificent, and peaceful, and different in every season of the year. We hope to share with visitors the joy of this special place when they come to taste our wines.

GEOLOGY

Development & Clones

Two-thirds of the land was planted with flowering plants (vetch) to improve soil health and structure. Trees were cut down on the remaining one-third of the land, and the stumps were removed to create open space. The machinery used to clear the remaining vegetation was also used to level the land, creating an even surface ideal for planting vines, and grading the land to ensure proper drainage. The land was contoured to enhance water runoff and reduced the risk of erosion. After clearing, the soil was deep ripped to break up any compacted layers, which allowed for better root penetration. Tilling followed to further prepare the soil, mixing organic matter and other soil amendments as needed. Once the soil was prepared, trellis systems were installed to support the vines as they grow. Vines were planted in the cleared and prepared soil, following the vineyard design layout. Early maintenance included protecting young vines from pests, managing weeds, and ensuring that the soil remains in optimal condition.

The vineyard began in 2018, planted to five acres of Chardonnay and 15 acres of Pinot Noir. We have planted several different Pinot Noir clones and a few different Chardonnay clones, which allows us to make complex clone blending. Different clones can bring unique flavor profiles to the wine. For example, one clone might contribute more fruity notes, while another adds spiciness or floral aromas. Blending these together can result in a wine with greater complexity and more layers of flavor. Some clones might be more acidic, while others might have higher sugar content. By blending different clones, we can achieve a better balance between sweetness, acidity, tannins, and alcohol, creating a more harmonious wine. Some clones contribute more tannins, which are essential for the wine’s structure and aging potential. Blending clones with varying tannin levels can create a wine that is enjoyable in its youth but also has the potential to age gracefully.

Farming Method

We have two defined management programs available in advanced farming method today. The sustainable management program conforms to the Low Input Viticulture & Enology (LIVE) certified practices and guidelines and also an organic management program which has been created using several resources over many years. We adopt an organic management which reduces chemical runoff, improves soil health and promotes biodiversity at our vineyard. We believe that healthier soils and vines can produce grapes with more complex flavors.

Viticulture

Born in the small town of Corral Nuevo, Veracruz, Mexico, Angel Martinez was introduced to agriculture early in life, working with his family to grow sugar cane, beans, and corn. In the fall of 1995, he moved to Oregon and began his journey in viticulture with a harvest at Domaine Drouhin Oregon alongside Buddy Beck. Following three successful harvests at Domaine Drouhin Oregon, Angel went to work for Buddy at Advanced Vineyard Systems, Inc. (AVS).

In 1999, Angel took on the role of foreman at AVS and by 2003, he had advanced to Vineyard Site Manager. His dedication and expertise led to his promotion to General Manager of Operations in 2007. In 2016, Angel bought AVS, marking a significant milestone in his career.

Angel’s vast knowledge of viticulture stems from his mentorship under Buddy Beck, as well as his academic pursuits at Chemeketa Community College. However, his most profound learning has come from nearly three decades of hands-on experience in designing, developing, and managing vineyards in the North Willamette Valley.

For Angel, agriculture is more than a profession—it’s a passion. He especially loves working in vineyards, where each season brings new challenges and opportunities to cultivate the finest fruit to produce exceptional wines.

Outside of work, Angel enjoys spending time in nature and engaging in outdoor activities. His hobbies include farming, fishing, camping, and cherishing moments with his wife, Nicole, and their daughters, Maria, Rosa, and Liliana.
