Nitrogen testing, another way to look at the grapes

We are working on a research project that will extend our previous work on how small wineries can measure manage nitrogen during the winemaking process. The new study will examine winegrowers use and measurements of nitrogen in the vineyards and will measure the nitrogen in grapes as they arrive at the winery. This measurement will provide growers with critical information on the nitrogen level of the grape must as they enter the winemaking process and will allow them to adjust their viticulture practices so they can deliver the grapes at the optimum nitrogen level.
