Q

What were the Missoula Floods? What geological effect did they have on the eastern Washington vineyards?

A

A catastrophic cycle of massive floods that occurred repeatedly at the end of the last ice age, some 12,000 to 18,000 years ago. Vineyards in eastern Washington are thus generally planted on sandy or silty loam soils derived from the flood-borne sediments.

Q

What is the soil type in the Rocks of Milton-Freewater? What style of wine does it lend itself nicely to?

A

It features a topsoil of basalt cobblestones that draws comparisons to the galets of Châteauneuf-du-Pape. It has incredible potential for Rhône-style wines.

Q

Where is Jory soil most commonly found in Oregon?

A

Jory (a well-drained volcanic origin soil) is common in the “red hills” of the Dundee Hills AVA. Gives a more elegant style.

Q

Where is Willakenzie soil most commonly found and what type of soil is it?

A

Willakenzie is a marine sedimentary soil, which is prominent on the valley’s westernmost slopes, such as in Ribbon Ridge. Gives a denser style of wine and darker fruit.

Q

What is the Van Duzer Corridor? Which AVAs does it impact the most and what style of wine does it warrant?

A

A gap in the Coastal Mountains that separates the valley from the ocean, directly impact McMinnville and the Eola-Amity Hills, generating more tannic styles of Pinot Noir.

Q

Why is rainfall so scarce in eastern Washington?

A

As Pacific air hits the Cascade Range it is pushed upward, cooled, and condensed into clouds, which quickly unleash their moisture as precipitation. Thus, the western slopes of the Cascades receive over 80 inches of rainfall annually, yet 50 miles to the east the climate is suddenly desert-like.

Q

What is the Yakima Fold Belt?

A

An area of south-central Washington where the low-lying topography of the Columbia Basin is striated by east-west ridgelines (or anticlines). The anticlines can rise to 4,000 ft while the valley floors (synclines) between them rarely exceed 1,000 ft above sea level.

17
Q

What is dual-trunk training and how does it help mitigate extreme winter temperatures in Washington?

A

With dual-trunk training, growers train two separate trunks on the same vine in parallel, just an inch or two apart, from the ground. Statistically, you can get winter damage to one but not the other.

18
Q

What two major geologic forces have shaped the bedrock material throughout the entire Columbia Basin?

A

A period of frequent and powerful volcanic eruptions that happened millions of years ago during the Miocene Epoch, and the more recent Missoula Floods.

19
Q

How have the Missoula Floods shaped Washington’s vineyard geology?

A

Between 18,000 ad 12,000 years ago, the dam of the great glacial Lake Missoula repeatedly broke as impounded water behind it overwhelmed and broke the ice, unleashing catastrophic floods two to three times each century. While this happened, sediment scooped up along the entire pathway of the flood was deposited all throughout Washington. Deep channels were carves into the basalt in some areas while deposits of gravel and other fine flood sediments accumulated in others.
