2015 Willamette Valley / Oregon Vintage

The Oregon Wine Board called 2015 another extraordinary, nearly ideal growing season. Warm winter weather continued through spring and summer, and bud break came in March, two to three weeks early depending on region and vineyard site. Higher than normal spring temperatures created exceptional conditions for bloom, flower and fruit set, and a warmer than usual summer produced grape clusters far larger than typical. Light scattered showers fell in late August and September returned to normal weather, while most growers slowed ripening by leaving extra fruit on the vine. Statewide harvest started around August 26, one of the earliest on record, and Oregon brought in an all-time record 84,949 tons. In Decanter's harvest report, producers called it a stellar crop.

Growing season

2015 opened warm and stayed that way. Warm winter weather continued through spring and summer. Bud break came in March, two to three weeks early depending on region and vineyard site. Higher than normal spring temperatures continued the early trend and created exceptional conditions for bloom, flower and fruit set. Summer stayed warmer than usual, and grape clusters grew far larger than typical as a result. Light scattered showers fell in late August, and September brought a return to normal weather. Most growers slowed ripening by leaving extra fruit on the vine, and as September settled into standard weather patterns, that fruit matured more gradually. Harvest started around August 26 across the state, one of the earliest on record. WillaKenzie Estate began picking as early as September 2. J.P. Valot of Silvan Ridge Winery and Elizabeth Chambers Cellar started harvest on September 8, the earliest in their 36 years, and finished on October 20. Willamette Valley wineries finished harvest by the end of September to early October. The crop was large, an all-time record 84,949 tons statewide. Valot also put Willamette Valley yields at three to four tons per acre, against the two to two and a half tons per acre that were the rule when he came to Oregon in 2001.

Wine style

J.P. Valot of Silvan Ridge Winery called 2015 another vintage of high yields and high quality, the second in a row. Leaving extra fruit on the vine let it mature more gradually and develop flavors balanced against acids. Harry Peterson-Nedry of Chehalem Wines saw the same color, beautiful fruit, concentration and suppleness as in 2014, with whites again fully ripe, texturally rich and yet balanced. In Decanter's harvest report, producers called it a stellar crop.
