    I want to express my slight disappointment in the research being done by the Northern Grapes Research Project. In this instance I will speak of the study on Frontenac regarding shaded vs unshaded fruit. There is already myriad research documenting the benefits of sound canopy management (i.e. cluster exposure)on fruit chemistry. The viticultural world knows this. I would urge the directors of these projects to push cold climate viticulture forward, rather than focus on the well established basics of quality viticulture.


    Hi Ethan –

    Thanks for the comment. Our recent postings are only the most striking aspects of the experiments we are doing.

    The posting on Frontenac and fruit exposure was an ‘extra’ item that I decided to do, as a supplement to the training trials. And the results, although not exactly surprising to me, are valuable from an extension standpoint. Yes, fruit exposure is a staple of the viticulture literature, but 2 grams lower on Frontenac in Northern NY is a concrete number that makes it ‘real’ for our growers here. I.e. its ‘extension’.

    There is a lot more, so please don’t judge on the basis of that one post. see our progress report at:

    We’re looking at training systems, in part, because some incur higher costs than others, and we want to know that the ‘extra’ practices will pay off in more yield or higher quality. Acid management is foremost among the quality concerns, and how we tweak the viticulture to minimize them is a goal of the project.

    I welcome any suggestions on what you would rather see happening, Ethan. Thanks again for the comment.
