Washington has long laid claim to Northwest Riesling. The grape is frequently the state’s most produced variety and Chateau Ste. Michelle is the world’s largest Riesling producer.

Things are different to the south where all of Oregon’s wine offerings stand in the shadow of its signature grape, Pinot Noir. Lately, however, a number of producers in Oregon have shown an increased interest in Riesling with several showing particularly impressive results.

At 718 acres, Riesling is Oregon’s fifth most planted variety behind Pinot Noir, Pinot Gris, Chardonnay, and even Syrah – though much of that grape is planted to the south. Acreage has risen from 558 acres in 2003 to a high of 798 in 2010 before receding slightly to its current number. In contrast, as of 2011 – the date of the last USDA acreage survey – Washington had 6,320 acres of Riesling under vine, though there are still more plantings of Cabernet Sauvignon, Merlot, and Chardonnay.

Washington and Oregon Rieslings are quite different in style. While Willamette Valley and eastern Washington aren’t too far from each other as the crow flies, the climates could not be much more different. If Washington’s tagline is “the perfect climate for wine” then Oregon’s would be “a difficult climate for wine”.

While Washington wine grape growing is usually relatively serene, Oregon grape growing is not for the faint of heart, as this year’s seven inches of rainfall in three September days so amply demonstrated. The Willamette Valley can be a challenging area to produce wine, though many succeed at creating world class offerings year after year despite the varying conditions. Lacking eastern Washington’s consistently warm, sunny days and the level of control that drip irrigation provides, it is always a wild ride in Oregon. These challenges are, of course, part of what allows the state to craft such compelling Pinot Noir, a grape that often thrives on the margins.

Given the cooler climate, Oregon’s Rieslings can often bring higher acidity than many of their Washington counterparts. They also command higher prices. For example, few Washington Rieslings (such as Eroica, Poet’s Leap, Pacific Rim’s Biodynamic Riesling, and several wines from Rasa) cost north of $20. In contrast, most of the wines reviewed below are above that mark.

The reason for this is that cropping at the tons per acre that Washington does would not be possible even in the warmest of years in Oregon. To wit, according to the Oregon Wine Board, Oregon’s 718 acres of Riesling produced 1,812 tons for 2.52 tons per acre. In contrast, Washington’s 6,320 acres produced 31,700 tons in 2011 for 5 tons per acre – and 2011 was a very cool year. It’s not uncommon for Riesling to be cropped much higher.

What’s the future of Oregon Riesling? A number of wineries have shown that top quality bottles can be produced in the state, and there are enough producers interested in the grape – Trisaetum alone makes six different bottlings – that Riesling should continue to make inroads. Still, with Oregon firmly established as Pinot Noir country and Washington producing an abundance of Riesling, it might remain a niche grape for the state. But that doesn’t make the existing wines any less enjoyable.
