Metabolomics and (craft) beers - recent advances

Craft beers have encountered a steady rise in popularity over the years, as these artisanal beers produced by microbreweries have responded to consumer preferences for added novelty in such beverages. With this gain in appeal and interest for the beverage, craft beers have also become a growing industry in many parts of the world, and the same can be said for research within the field. This also extends to the chemistry of craft beers, where one method of exploration involves that of metabolomics, appropriately addressing the multi-faceted aspects of craft beer development and chemistry. Alongside advances in metabolomics in general beer and brewing research, the field also mirrors potential in growth. This review touches on relevant aspects of the beer industry and brewing process as preliminaries for discussions on advances in the field of beer metabolomics, leading to the application of metabolomics in pursuit of studying craft beers; future directions, challenges, and opportunities are also presented.
