Then ultimately, you don't know where the wine is going on its trajectory, so sell it fast." Green flavors in wine Herbaceous or green flavors, especially in red wines, are often associated with unripe grapes or fruit of lesser quality, and these flavors can have a masking effect on more preferable fruity flavors. One class of odor- ant compounds, the methoxypyrazines (MPs), is responsible for green flavors sometimes found in Bordeaux cultivars such as Cabernet Sauvignon, Cabernet Franc and Merlot as well as in hybrid grapes with some vinifera parentage. These compounds can be detected at concentra- tions as low as 1 part per trillion. According to Justin Scheiner, viticultur- ist for the Texas A&M AgriLife Extension Service in College Station, Texas, the best way to manage green flavors caused by MPs starts in the vineyard. MPs are predomi- nately located in the skins of the grapes, with significant concentrations in the stems or the rachis of the berries. research in New york has shown that light exposure of clusters affected the level of concentra- tion of MPs in the grapes, with more light resulting in lower MPs. High-vigor vines also had higher levels of MPs, but cluster thinning to reduce the crop load and im- prove ripening may not result in lowering the MPs in the crop that was left. Control of vigor is important, as excessive vigor can also cause shading of clusters. In addition, green harvest after véraison can help with asynchronous ripening problems, and by The best way to manage green flavors caused by MPs starts in the vineyard.
