Best Paper Awards
Each year, the ASEV Best Paper Awards Committee completes an evaluation of all research papers published in the American Journal of Enology and Viticulture for the prior year. The committee selects one paper in the field of enology and one in the field of viticulture that is deemed outstanding in its content and a substantial contribution to the field.
Each best paper receives a monetary award to be shared among the authors. Each author is also awarded a plaque, complimentary National Conference registration, and an invitation to the Board of Directors dinner held at the conference site. A plaque is presented at the ASEV National Conference in June to those authors who attend. The awarded papers are also designated as such and are made freely available on the AJEV Online website.
