Mackey Vineyards is located in the highly coveted southeast part of the Walla Walla Valley in a deep canyon on the south fork of the Walla Walla River. The site itself is reminiscent of the prized vineyards of Bordeaux with river rock studded soils, and higher elevation, which provides not only frost protection, but moderate temperatures ideal for French-style wines.
Other Sources of Fruit We Use
Mc B Vineyard spreads across a hillside near the small hamlet of Lowden, Washington. At only 550 ft in elevation, it routinely records some of the warmest temperatures in the Walla Walla Valley. After sunset the temperature drops rapidly as cooler air floods in from the Blue Mountains foothills and pools on the surrounding valley floor. This diurnal shift in temperature, which commonly exceeds 40°F, preserves acidity and prolongs the ripening period so that sugar levels and flavors are in balance. The soils of Mc B Vineyard consist of layers of sand and silt deposited by the Ice Age Missoula floods overlain by wind-deposited silt (loess).
Les Collines Vineyard is situated between 1200 and 1400 ft elevation in the foothills of the Blue Mountains five miles southeast of Walla Walla. The soils of Les Collines consist of deep silt loams derived from wind-deposited silt known as loess. The soils are both well drained and have excellent water holding capacity and supplemental irrigation is used sparingly. This vineyard has one of the longest ripening seasons in the Walla Walla area as it often lies above the cool air that pools on the valley floor.
Yellowbird Vineyard lies at an elevation of 1450 ft. on a southwest-facing slope in the valley of Mill Creek, five miles east of Walla Walla. The combination of deep silt-loam soils and an annual precipitation of 20-24 inches of precipitation permit the grapes to dry-farmed (grown without supplemental irrigation). The vineyard benefits from a daily pattern of airflow that is common in the Mill Creek Valley during the summer months. Warmer lighter air pushes up into the Mill Creek valley during the day, displacing cooler heavier air. Near sunset, the airflow direction reverses as cool air descends from the nearby Blue Mountains. The fluctuating winds moderate the climate near Mill Creek and encourage balanced ripening.
