1
Q

Describe Oregon’s climate and explain why it is suited to grapes such as Pinot Noir. (4)

A

More northerly latitude + coastal influence –> cool-moderate climate

Coast Range provides partial protection from cooling Pacific winds

Long daylight hours –> aid ripening

High levels of rainfall but usually in winter e.g. Willamette Valley gets 1000mm annually, but only 200mm Apr-Sept

Q

What are the most widely planted grape varieties in Oregon?

Explain the importance of clonal selection using two examples.

A

Pinot Noir - 57% of plantings

Pinot Gris

Chardonnay

Also: Syrah, Cab, Merlot, Riesling

First clones were designed for yield e.g. Wedanswil & Pommard Pinot Noir –> complemented Dijon clones in 1980s –> enabled matching of clonal type to site conditions

E.g. Wente and 108 Chardonnay –> difficulty ripening –> Dijon clones ripen earlier –> some ripen too early given climate change –> producers switching back to heritage clones

Q

Describe the style of and winemaking used to produce Pinot Gris.

A

Varies from whole-bunch, SST protective –> skin-contact, barrel fermentation, lees-ageing

Pear, peach, melon –> nutty, honeyed aromas

Dry or off-dry (trend towards off-dry), med-med(+) acid, med-full bodied

Good-VG; mid-priced

Q

Describe the style of and winemaking used to produce Chardonnay.

A

Generally whole-bunch pressed, ferment and maturation in oak (lots of old oak), full malo, lees contact

Lees often not stirred –> accumulation of sulfur compounds –> struck match

Good-VG / mid-priced-premium

Q

Describe the growing environment of Willamette AVA.

A

Coast Ranges protect from most of Pacific influence –> warm, dry summers

Pacific influence via gaps in Coast Range means the coolest and wettest part of Oregon

Northerly latitude means long daylight hours during growing season

High diurnal range due to warm air rising in Oregon interior pulling cold air from the coast + lack of humidity

Q

Describe how differences in soil type within Willamette Valley influence planting and training decisions (2)

A

Fertile loam –> valley floor –> best for Pinot Gris, where Pinot Noir planted large vine training systems (e.g. Henry Scott) used to managed vigour

Sandstone, basalt, loess –> high altitude –> cordon-trained/replacement-cane pruned –> easier to manage canopy

Q

Using two AVAs, explain the range of growing environments within Willamette.

A

Dundee Hills protected from the Pacific by Coast Range so warmer/drier, variation in altitude up to 325m, red clay soils retain water during summers (no access to irrigation)

Van Duzer Corridor break in Coast Range –> afternoon breezes –> cools but can also impact flowering/fruit set + ripening (stomata) –> impact on style and disease pressure

Q

Compare and contrast the growing environment in southern Oregon to the Willamette Valley.

How do plantings differ?

A

Latitude is more southerly –> warmth

Cooling influences from river valleys channelling in sea breezes (like Will) + mountains (altitude and cool air, unlike Will)

Rainfall mainly in winter like Will but added temp means summer irrigation essential

Plantings of wider array of varieties

  • PN still most popular (40%) and PG 2nd
  • Syrah, Tempranillo 3rd and 4th

Q

Contrast the AVAs of Umpqua Valley and Rogue Valley.

A

Umpqua - mix of altitude, aspect and soil –> relatively cool due to latitude and breezes vai Umpqua River gorge –> mainly makes PN, PG, Gewurz, Riesling

Rogue Valley - furthest south - warmest/driest in Oregon - altitude 250-950m –> Merlot, Cab, Syrah, Temp

Q

How does Oregon labelling law differ from federal labelling law?

A

Place Requires 100% of grapes to be from in-state to be labelled as such, 95% to be labelled as appellation

Variety >90% min cf. 75%

Estate bottling 100% of grapes from within winery’s AVA, wine finished on estate

Q

Compare the size of Oregon’s production to California.

How large are most producers?

How do producers acquire grapes?

A

Produces 55m bottles - 1.4% of total production cf. to 80% in California –> but rapid growth

Small - 75% produce <5,000 cases

Many are estates - 52% use own grapes

Q

How important is DTC for Oregon wine?

Where is Oregon wine sold?

A

Very important ~25% sold DTC including tasting rooms, wine clubs and online orders

16% sold in state - hospo and retail

60% in rest of US

2.5% exported - Canada, UK, Japan
