Bark and grape microbiome of Vitis vinifera: impact of geographic patterns and agronomic management
Tiziana Nardi, CREA – Viticulture and Enology Research Centre, Italy
In recent years, the concept of “microbial terroir” has been introduced in the frame of the more renowned notion of “vitivinicultural terroir’, since several studies demonstrated that wine characteristics are related to regional microbial community compositions.
Most of the existing research focused on grape berries microbiota. Using next-generation sequencing for the first time, this work studies the epiphytic bacterial community of vine bark and its relationships with grape microbiota.
The evidence of a “microbial terroir” seems to be even more marked in bark than in berries, possibly due to its permanence over time and to its physical, proximity to the soil. Moreover, this study suggests that geographic and anthropogenic factors impact both bark and grape bacteriomes.

Wine is fundamentally a high-intervention product, and along all stages from harvest to bottling it's our job to guarantee safety and quality, but it's also up to us to research, experiment, and ad...
Producing a wine according to our oenological objective, wanting to express the variety, but adapting practices according to the sanitary status of the grapes, is continuous experimentation. We aga...
Phenolic composition of grapes has an important impact on the final intrinsic quality of (red) wines. Wine taste, mouthfeel and colour are driven principally by phenolic compounds present in grapes...
For the production of quality sparkling wines, it is important to ensure the separation of the correct phenolic profiles of must fractions. Find out how UV-Visible spectroscopy, together with chemo...
Chemical, biochemical and physiological factors influence the composition of the retronasal aroma during wine consumption, but not only tannins influence mouthfeel: anthocyanins do too. New methods...
