Vineyard[/caption]In the early 1960s, the accepted wisdom was simple. You could not ripen Pinot Noir in Oregon. Too cool, too wet, too marginal. The people whose job it was to know said to plant something safer. A few growers planted Pinot anyway.

They were right, the wisdom was wrong, and the valley they bet on is now spoken of in the same breath as Burgundy.

The Willamette Valley runs south from Portland, a long green trough between the Coast Range and the Cascades. It sits near the 45th parallel, the same band of the globe that holds Burgundy and Bordeaux, and it has the one thing cool-climate Pinot needs most: a long, gentle growing season that ripens the fruit slowly and never cooks it. Marine air slips in through gaps in the Coast Range, the Van Duzer corridor chief among them, and pulls the temperature down after dark. Slow ripening, cold nights, bright acid. It is, almost eerily, Burgundy’s recipe in another hemisphere.

Up in the Dundee Hills, the soil turns red. This is Jory: a volcanic clay-loam weathered from ancient basalt, iron-rich and free-draining, and it gives some of the state’s most perfumed, earth-driven Pinot. Other corners of the valley sit on marine sedimentary soils that read differently in the glass, a little more red fruit and a little less earth. The Eola-Amity Hills catch the most wind and lean toward structure and tension. The valley is not one place. It is a dozen, and the wines tell you which one they came from.

What unites them is restraint. Where a warm climate pushes Pinot toward plush, sweet red fruit, Oregon’s cool margins pull it the other way: red cherry and raspberry, yes, but laid over something savory and earthen, the smell of a forest floor after rain. If you tasted the Russian River Pinot we covered a few weeks ago and found it generous and round, Oregon is the same grape with the volume turned down on fruit and up on earth. Two honest conversations about one grape.

Three steps into Oregon Pinot, by place rather than label:

• Affordable: a broad Willamette Valley bottling. Bright red cherry, a light dusting of earth, easy and aromatic.
• Better: a single-area Pinot from the Dundee Hills or Eola-Amity. More forest floor, finer structure, a clearer sense of its hillside.
• Luxury: a single-vineyard wine from old vines on the volcanic slopes, built to age, where the fruit slowly gives way to mushroom, tea leaf and damp earth over years.

Place comes before packaging, always. Before the grape, before the producer, there is a cool valley on the 45th parallel, red volcanic soil, and a handful of growers who did not listen. Taste that, and the wine makes sense.

SENSORY PAUSE   Pour an Oregon Pinot and let it warm a minute in the glass. Look past the cherry for the note underneath: damp earth, fallen leaves, something savory. That note is the cool valley speaking.
