   This is the first meta-taxonomic study on microbial communities during wine aging using high-throughput sequencing (HTS) techniques. 
   The wines obtained from two different grape varieties were aged at two different cellars and compared based on time of wine aging in the barrels (12 months), previous usage of the barrels, and differences between wine aging in oak barrels or glass bottles. 

   The results show that the microorganism composition of barrel-aged wines was similar at both cellars and hint at the possibility of a common and stable microbiota after aging in the absence of exogenous alterations.
