Microbial communities of vineyard BRO11-BRO12 soils (GeoChip)

In this work, we used a functional gene microarray approach (GeoChip) to assess the soil microbial community functional potential related to the different wine quality. In order to minimize the soil variability, this work was conducted at a “within-vineyard” scale, comparing two similar soils (BRO11 and BRO12) previously identified with respect to pedological and hydrological properties within a single vineyard in Central Tuscany and that yielded highly contrasting wine quality upon cultivation of the same Sangiovese cultivar Three replicates of each top-soil hosting vine plants yielding grapes and wine of different quality were collected and compared among the two areas (BRO11 and BRO12) within the same vineyard in Brolio (Tuscany, Italy)
