Cher ries on Mazzard Rootstock Available for 2014 Celebrating 75 Years of Superior Fruit Selections 1938 - 2013 800-654-5854 Arandell is highly resistant to powdery and downy mildews and botrytis bunch rot. Juice analysis of more than 30 juice lots produced from 1995 to 2012 showed a pH of 3.0, titratable acidity of 12.1 grams perliter, and 19.5° Brix, on average. Aromella is recommended for use in aromatic, Muscat white wines, as a varietal or blend. Red variety Arandell is a midseason red wine grape variety with a high degree of natural disease resistance. It is from a 1995 cross and is the first named variety to come out of Cornell's no-spray block established by Reisch in the late 1980s. Arandell is highly resistant to powdery mildew, downy mildew, and botrytis bunch rot. Even under heavy disease pressure, symptoms are rarely seen, though both mildews have been observed on foliage late in the season. Botrytis bunch rot has never affected more than 2 percent of fruit harvested. It is still moderately susceptible to black rot and phomopsis. Over a three-year period, average yields were six tons per acre for grafted vines and four tons for own-rooted vines planted on a 9- by 7-foot spacing. However, yields reached as high as eight tons per acre in grafted vines, suggesting that cluster thinning may be necessary some years. Vines of Arandell are moderately winter hardy. Tests of midwinter primary bud hardiness showed 50 percent bud kill at around -13°F. Limited trunk damage has been noted after winter lows of -15° to -16°F, but without crown gall disease. Research wines produced from Arandell are densely colored with light to moderate tannins and have notes of dark berry fruit, tobacco, and hints of black pepper or cedar on the finish. Brix at harvest averaged 19.5. The pH level averaged 3.3 and titratable acidity 105 grams per liter. Arandell has potential as a variety for organic viticulture. Growers should be able to produce clean, ripe fruit with a minimal spray program, Reisch said. The names came from a name-that-grape contest by Cornell that started as an e-mail to grape extension and research colleagues, was featured in the Cornell Chronicle newspaper, and then went viral. The story was picked up by local and national news media, and mentioned on the National Public Radio Morning Edition and Bon Appétit magazine online, as well as in several wine blogs. The result was more than 1,100 name suggestions from the United States and other countries. Arandell was suggested by a wine enthusiast from Alaska and is a combination of the Spanish word "arándano" for blueberry and "ell" for Cornell. A winemaker from California coined the name for Aromella. Vines can be purchased from licensed nurseries. Virus-tested cuttings may be obtained from Foundation Plant Services at the University of California, Davis. E-mail for a list of licensed nurseries. • GOOD FRUIT GROWER April 15, 2013 39
