                                Technical Abstract: This article covered the initial portion of our exploration of how altered vine nutrient regimes and sample preparation methods influence 'Pinot noir' grape nitrogen (N) content and composition. We mainly focused on ammonia and free amino acids and recalculated these values as YAN (yeast assimilable N), an important value often measured at the winery and adjusted for a healthy fermentation.
