New article on comparison of methods in wine metabolomics

Qualitative factor-based comparison of NMR, targeted and untargeted GC-MS and LC-MS on the metabolomic profiles of Rioja and Priorat red wines. 

Dimitrios Kioroglou, Albert Mas, M. Carmen Portillo

Foods 9, 1381 :

    Wine origin and ageing are two factors related to wine quality which in turn is associated to wine metabolome. Currently, new metabolomic techniques and proper statistics procedures allow accurate profiling of wine metabolome. 

    In the current study, we implement NMR, targeted and untargeted GC-MS and LC-MS metabolomic analytical techniques so as to gain insights into the volatile and nonvolatile wine metabolome composition of red wines from two cellars located in the only two Spanish Qualified Appellations of Origin:DOQ Priorat and DOCa Rioja regions. 

    The results suggest that a combination of different metabolomic techniques is necessary for a complete overview of the metabolome changes and ease the selection of the correct methodology depending on the specific factor investigated.

New article on meta-taxonomics of wine microbes

High-Throughput Sequencing approach to analyze the effect of aging time and barrel usage on the microbial composition of red wines. 

Dimitrios Kioroglou, Albert Mas, M. Carmen Portillo

Frontiers in Microbiology 11, 562560, 2020:

   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.

M. Ángeles Morcillo and Aitor Balmaseda showed DNA extraction at TV

Last Tuesday 21st July our group colleagues M. Ángeles Morcillo (postdoctoral researcher) and Aitor Balmaseda (PhD student) were interviewed in TV (TAC12, Tarragona) in a magazine show called "Som-hi" ("Come on" in Catalan). As we can see in this video, they showed in a very easy way how to extract DNA from strawberry and from yeasts.
