Grape Evaluation using VIS/NIR Spectroscopy

grape vis nir spectroscopy

The food sector could be greatly helped by new analytical methods that are accurate, rapid, and integrated into the production process to meet consumer demand and respect limits imposed by international standards.


Grape composition at harvest is one of the most important factors determining the future quality of wine. Measurement of grape characteristics that impact product quality is a requirement for vineyard improvement and for optimum production of wines. Inspection of grapes upon arrival at the winery is a critical point in the wine production chain. This check determines both the quality of the wine and the viticulturers fees. This control is usually performed only on small samples that are not always representative of the whole, so the importance of this operation is easy to understand, as it determines the economic value of the entire stock.
