Vineyards of Washington Wine Country

grapes from vineyards

Washington ranks the second in the United States in the production of wine and exports to over 40 countries around the world. The state’s location above the 46th parallel north allows vineyards in Washington’s major wine growing regions 17 hours of sunlight in the summer. Eastern Washington experiences a wide temperature variation (up to 40°F difference between daytime highs and nighttime lows). One of the best natural locations for growing grapes which end up balanced between ripe sugars (which will equate to alcohol in the wine) and crisp acidity is a difference between day time and night time temperatures – or, diurnal shift.  Washington State has some of the most dramatic fluctuations of any wine region in the world. In addition, the rich soil deposits brought on by millions of years of glacier movements, along with annual rain fall of 8 inches brought on by the  rain shadow of the Cascade Range, make Washington one of the best regions to produce exquisitely delicious wine. Common vineyard fungal disease and grey/black rot require a humid environment.  Due to its arid climate, Eastern Washington vineyards are remarkably fungus free; as a result, very few chemical based anti-fungicides are required, leading to sustainable vineyard practices that leave vibrant, healthy, lively soils and water sources. Underground aquifers run through levels of basalt lava flow. We have tapped these wells for our lake which also serves as our water reservoir.  Our brand new, computer controlled/timed irrigation systems are used to manage the growth of our vineyards and row crops. To take advantage of the sun exposure in the Northern hemisphere, Eritage is planting its vines on the slopes of the foothills of basaltic uplifts. This also adds to the drainage capabilities for the odd storm in the Columbia Valley. Eritage will have a growing season of 190 to 220 days. Cheers!
