Abstract or Summary
  • By now, all members of the Oregon Wine and Grape industry are familiar with the concern expressed by the Center for Science in the Public Interest (CSPI) over the presence of the compound ethyl carbamate, popularly called urethane, in wine. This material has been demonstrated to induce cancer in laboratory animals, and has generated a concern in CSPI over its potential harm to humans. The American wine industry, via the Wine Institute and the Association of American Vintners, has established a cooperative effort to determine levels of ethyl carbamate in wines, to ascertain causes of the presence of this substance, and to significantly lower these levels over a period of time. Details are outlined in a letter addressed to all wineries from the Wine Institute committee on ethyl carbamate, dated July 20,11988. It should be read carefully before harvest begins, since it also has some practical suggestions on means by which levels of urethane may be minimized. In September of 1988, a survey initiated on levels of this compound in the wines of Oregon, financed by the Oregon Wine Advisory Board, and conducted by Barney Watson and Richard Scanlon of Oregon State University. My task was to collect samples from those wineries who wished to participate, and relay those samples to OSU, coded to prevent identification of source; OSU knew only the color of the wines ... obviously. Fifty-five samples were collected from twenty-one wineries and shipped "blind" to OSU, where analysis was performed. Analyses are now complete, and the following is a summary of findings.
