Q

Explain the climate of the Willamette Valley and the influence the Pacific Ocean has on it

A

WV is one of the coolest and wettest areas in Oregon. The coastal range mountains offer some protection from Pacific cool/wet influences but breaks in it offer direct influence. Summers are still warm and dry, and due to latitude sunshine hours are high. Diurnal range is high due to warm inland air pulling cool Pacific air inland.

Q

Is irrigation allowed in Willamette Valley?

A

Only if growers dig their own ponds and retain their own water, river water is only permitted for the longest established vineyards.
Most growers are small plot holders, dry farming is prevalent.

21
Q

Dundee Hills is warmer or cooler than other AVAs and why?

A

Warmer due to protection from Coastal Range to west and Chehalem Mountains to north enabling full fruit ripeness

22
Q

Soils of Dundee Hills

A

Red Iron Rich clay - important for water retention during dry summers to avoid vine shutdown during summer

23
Q

Which sub AVA of Willamette Valley has the most plantings?

A

Chehalem Mountains

24
Q

ASL of Chehalem Mountains

A

60-305 m
Highest point of ridge - 500m - acts as windbreak

25
Q

Sub AVA of Chehalem Mountains

A

Laurelwood District

26
Q

Highest altitude AVA in Willamette

A

Laurelwood- 500m

27
Q

This sub AVA of the Willamette Valley is small, low in elevation, and protected from winds by the Chehalem Mountains providing a warm growing area. Soils are deep but poor in nutrients, controlling vine vigor, and have moderate water retention properties leading to concentrated grapes.

A

Ribbon Ridge

28
Q

This sub AVA is in the NW of Willamette Valley. It is a south facing bowl containing horseshoe shaped eroded hills of warm, free draining soils. The coastal range provides a full rain shadow effect providing wines with roper fruit flavors, fuller body, and lower acid than other sub-AVAs

A

Yamhill-Carlton District

29
Q

What influence does the Pacific Ocean have in the Van Duzer Corridor AVA? And what is the effect on the vines?

A

There is a break in the coastal range that funnels cool winds in during the afternoon. Early in the season the winds can disrupt flowering and fruit set leading to lower yields. Later in the season the winds can cause the leaf stomata to close which slows ripening. The cooler wind also slows ripening, retaining acid, slowing sugar accumulation and allowing aromas and flavors to develop. It also reduces disease pressure.

30
Q

Eola Amity Hills AVA is influenced by the same cool air as the Van Duzer Corridor however what leads to variation here?

A

Eola Amity Hills is a ridge of north to south hills that offer a range of aspects and altitudes offering some warmer, more sheltered sites

31
Q

This sub AVA of Willamette Valley is located between the Yamhill Carlton and Van Duzer Corridor AVAs and influenced by both. Cool winds come from its southwest, Van Duzer, and heat from its north, Yamhill Carlton.

A

McMinnville

32
Q

Name two factors that allow for late ripening in Tualatin Hills AVA

A

Pacific Ocean cool/wet air 24 miles away
Soils are Laurelwood windblown loess- poor in nutrients

33
Q

Southern Oregon AVA is warmer or cooler than Willamette Valley?

A

Warmer but cooling influences come from mountains (altitude and cool air descending) and river valleys (channels cool breeze in afternoon/evening) = high diurnal range

34
Q

Southern Oregon AVA are or are not permitted to irrigate with river water?

A

They are. Many growers were ranchers previously and therefore allowed. Dry farmed vineyards are planted to Rhone varieties.

35
Q

Most planted variety of Southern Oregon AVA?

A

Pinot Noir

36
Q

The coolest, most northerly sub AVA in Southern Oregon that specializes in Pinot Noir, Pinot Gris, gewurz, and Riesling.

A

Umpqua Valley

37
Q

Rogue Valley’s cooling influences come from?

A

Altitude- 250-900m from Klamath Mountains and Cascade Range
And
Cooling breezes drawn in from pacific by Illinois and applegate River valleys

38
Q

Rogue Valley AVA grapes?

A

Merlot, cab sauv, Syrah, Tempranillo, Pinot Noir

39
Q

Climate in Walla Walla Valley AVA?

A

Arid continental with hot, dry summers

40
Q

Walla Walla Valley specializes in what varieties?

A

Cab sauv, Merlot, Syrah

41
Q

What sub AVA is located entirely within Oregon that has distinct basalt stones that radiate warmth and allow for extra ripening?

A

The Rocks District of Milton Freewater

42
Q

Columbia Gorge AVA has cooling influences from what?

A

The west is closest to Pacific Ocean and has cooler, wetter weather than the east. Vineyards are planted up to 600m offering cool sites and winds are funneled by the gorge which also cool.

43
Q

The west of Columbia Gorge is planted to what type of varieties vs the east?

A

Burgundian and Alsatian vs Rhone and Iberian

44
Q

How much of the Columbia Valley AVA is in Oregon?

A

About 1/4

45
