Chambourcin is a hybrid red wine grape that can consistently produce high-quality wine in many humid climate New World sites including New Jersey and much of the mid-Atlantic region of the United States. Many of these regions can also produce high-quality V. vinifera-based red wine blends. This study examined the influence of chambourcin on the quality of red wine blends of V. vinifera varieties in blinded tasting sessions involving three groups: consumers, wine professionals (non-winemaking), and commercial wine makers. Consumers preferred or rated equally the chambourcin containing blend to the non-chambourcin containing blend. Among wine professionals and commercial wine makers, there was no preference among blends. Even experienced wine makers could not identify wines containing chambourcin and did not rate wines lower if they thought the wines contained chambourcin. This study suggests chambourcin does not detract and rather may enhance high-quality red wine blends and further suggests that wine blend categorization may be better based on hedonic character and not grape genetic heritage. Inclusion of high-quality hybrid grapes, like chambourcin, in red blends of V. vinifera may enhance sustainability of viticulture in New World grape growing regions without sacrifice in the quality of wine that can be produced.

Purpose: To identify factors significantly influencing accrual to clinical protocols by analyzing radiation Patterns of Care Study (PCS) surveys of 3,047 randomly selected radiotherapy (RT) patients.Methods and Materials: Patterns of Care Study surveys from disease sites studied for the periods 1992-1994 and 1996-1999 (breast cancer, n = 1,080; prostate cancer, n = 1,149; esophageal cancer, n = 818) were analyzed. The PCS is a National Cancer Institute-funded national survey of randomly selected RT institutions in the United States. Patients with nonmetastatic disease who received RT as definitive or adjuvant therapy were randomly selected from eligible patients at each institution. To determine national estimates, individual patient records were weighted by the relative contribution of each institution and patients within each institution. Data regarding participation in clinical trials were recorded. The factors age, gender, race, type of insurance, and practice type of treating institution (academic or not) were studied by univariate and multivariate analyses.Results: Overall, only 2.7% of all patients were accrued to clinical protocols. Of these, 57% were enrolled on institutional review board-approved institutional trials, and 43% on National Cancer Institute collaborative group studies. On multivariate analysis, patients treated at academic facilities (p = 0.0001) and white patients (vs. African Americans, p = 0.0002) were significantly more likely to participate in clinical oncology trials. Age, gender, type of cancer, and type of insurance were not predictive.Conclusions: Practice type and race significantly influence enrollment onto clinical oncology trials. This suggests that increased communication and education regarding protocols, particularly focusing on physicians in nonacademic settings and minority patients, will be essential to enhance accrual.
