Special Issue Information

Dear Colleagues,

Beer has, historically, been one of the most broadly consumed beverages in the world, developed from a simple process involving various naturally occurring microbes. Brewing has now become a multistage industry where desirable and specific microbial activity is closely controlled. Unfortunately, contamination can occur throughout the supply chain, affecting raw materials, the beer in process, and the final products. Due to a series of intrinsic antimicrobial characteristics, beer is resistant to the growth and survival of undesirable microorganisms. Extrinsic factors, including the acidification of malt, the mashing process, wort boiling, pasteurization, filtration, and cold storage, also lower the risk of contamination by or the proliferation of microorganisms. The combination of intrinsic and extrinsic factors provides a prime example of hurdle technology, where a combination of obstacles that may not be individually restrictive can prevent contamination. Fortunately, contamination within the brewing chain is rarely an issue of food safety.

In this Special Issue, we invite authors to lead investigations into this topic and to contribute to our knowledge on the microbial activity seen at the various stages of beer production, from the field through the production plant to the point of consumption.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Fermentation is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2100 CHF (Swiss Francs).

Recent studies have shown that the use of non-Saccharomyces yeasts, either alone or in co-fermentation with Saccharomyces cerevisiae, can enhance the development of specialty beers with distinctive compositional characteristics. This study aimed to evaluate the main compositional and sensory differences between American Pale Ale (APA) beers produced using the commercial strain S. cerevisiae US-05 as a single starter (Test 1), and those produced through sequential inoculation with Metschnikowia pulcherrima 62 followed by S. cerevisiae US-05 (Test 2). Analyses focused on key chemical parameters and volatile compounds at the end of primary fermentation (F1) and after 20 days of refermentation at 20 °C (F2). After F1, Test 2 samples showed higher concentrations of glycerol and higher alcohols (isoamyl alcohol, benzeneethanol) and lower concentrations of esters (isoamyl acetate, ethyl hexanoate, ethyl octanoate) compared to Test 1. After F2, the differences in higher alcohol content became less significant, whereas ester concentrations, particularly ethyl acetate and ethyl octanoate, were significantly higher in Test 2. Sensory evaluation revealed that beers from Test 2 exhibited more pronounced floral and fruity notes and achieved higher overall scores in the panel assessment. These findings indicate that sequential inoculation with M. pulcherrima 62 followed by S. cerevisiae enhances both the chemical complexity and sensory appeal of APA beers, highlighting the strain’s potential as a valuable tool for developing specialty beers with unique aromatic profiles.
