Bottle to Bottle Variations Study

Different bottles of a particular wine (same label, same vintage etc.) bought from the same place should all be identical, but in reality they can have major differences, due to various factors. For example, a study that we carried out in France on 25 batches of wines purchased from retail outlets revealed the existence of chemical differences within the same batch for 10 of the wines studied. Sensory variations were also observed for almost half of these batches.

The results of this study show that these bottle to bottle variations within the same batch, even though known in the industry, tend to be underestimated. Within the context of this research, we have developed a comprehensive procedure to assess these variations from one bottle to the next within the same batch of wine. This allows us to identify the potential source of the variations observed and recommend strategies for the wineries to guarantee consistency in the wine that they put on the market.
