Wine Proteomics

I recently wrote about a paper on beer proteomics.  A recent review by Righetti et. al., is a concise and comprehensive overview of the field of wine proteomics.  The review summarizes many of the recent reports on the protein content of wine and digs into many of the recent controversies of the field, including the well publicized report on allergens in wine.  The real center of this review is the results of 3 publications from the review's authors using a peptide library enrichment technique that has broad implications on wine technology.  In the studies in question, the authors demonstrated the ability to detect trace quantities of wine impurities including, but not limited, to fining agents and fungal proteins.  This paper is both and extremely interesting and entertaining read due to the authors' brassy tone and obvious sense of humor.
