Dear Colleagues,

Alcoholic beverages, obtained by fermentation or by distillation of a fermented product of agricultural origin, are composed of hundreds of volatile compounds. These compounds have been extensively studied due to their impact on the aroma of beverages, knowing that there are odorant compounds and odourless compounds. Given that the aroma of beverages is a determining factor of their quality and acceptability for consumers, volatile compounds with an impact on the aroma of alcoholic beverages deserve particular attention from researchers. On the other hand, some of these compounds have been studied due to their importance in food safety, such as methanol or ethyl carbamate, among others. In addition, the occurrence/absence or the amount of some compounds could be used as markers of the used technology or the signal of a product fault.

Volatile compounds, belonging to many chemical families, are present in alcoholic beverages in very different amounts, arising either from raw material (e.g., grapes, barley, hops), secondary metabolites of fermentation (yeast/bacteria) or from aging when applied (e.g., in oak wood).

In recent years, the search for diversification of products and processes, such as the use of different raw materials and fermentation with different yeasts or aging with different woods, poses new challenges to the study of volatile compounds in alcoholic beverages.

In this context, this Special Issue aims to focus on new approaches to volatile compound methods, as well as new approaches in their sensory evaluation for the study of alcoholic beverages (fermented beverages from different raw materails such as cider, wine, beer, or other and distillates such as spirits). Possible subjects comprise but are not limited to the following:

• New analytical approach for volatile quantification;
• Olfactometric studies;
• New sensory approaches;
• Different technologies and their influence on volatile composition and/or sensory composition;
• New raw material and its influence on volatile composition and/or sensory composition.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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. Applied Sciences is an international peer-reviewed open access semimonthly 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 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
