Thanks to the members of the ASEV Best Paper Awards Committee who volunteered their time to select the one paper in the field of enology and one in the field of viticulture that they deemed was outstanding in content and provided a substantial contribution to the field. The committee completes an annual evaluation of all research papers published in the AJEV for the prior year.
