Craft beer represents a dynamic and creative segment within the food and beverage industry, emphasizing quality, aroma, health, sustainability, locality, and tailored brewing techniques. This paper explores the multifaceted roles of craft beer’s production and consumption growth dynamics. Both a bibliometric analysis and a systematic literature review were conducted on a sample of 239 scientific papers to provide an in-depth evaluation of the main characteristics and influences that craft beer has in the field of food science. Based on the identified roles of craft beer/breweries in the selected sample of literature, a conceptual framework was constructed to serve as a guideline for policymakers and different stakeholders. In this way, our findings enrich the existing literature and contribute to a better understanding of craft beer production and surroundings, which can be beneficial for promoting sustainable policies and innovative strategies for the growth of small/micro-producers and entrepreneurs in this niche market. Furthermore, this evidence can stimulate clear and ethical information to enhance consumers’ knowledge and agendas to strengthen the identity of local communities.

The hop variety Saaz is well known over the world and is usually used for brewing of lager beers. Recently, the new related varieties Saaz Late, Brilliant, Comfort, and Shine were registered. Information about these varieties is splintered and often available only in the Czech language in regional journals. This review (i) summarizes previously published data (breeding history, genetic data, basic parameters such as yield, sensory profile, concentrations of key technologically important hop compounds), (ii) presents long-term data (2004–2021), and (iii) shows similarities/differences among these varieties. All Saaz varieties are typically fine aroma hops with a relatively low content of alpha bitter acids ranging from 5 to 7 wt%, cohumulone amounts lower than 30% rel., and hop oil content of about 1.0 wt%. Even though the new varieties have no identical chemical parameters to the original Saaz, they can substitute this established standard as well. Furthermore, the varieties Saaz Comfort and Saaz Shine show high resistance to Pseudoperonospora humuli as well as very good tolerance to drought.

The effect of oak chips on the phenolic composition, color characteristics, and antioxidant capacity of Bobal red wines caused by contact with oak chips at different stages of the winemaking process has been studied. Performance liquid chromatography–diode array detection (HPLC-DAD) was used to determine the detailed phenolic composition of wines and antioxidant activity, and chromatic characteristics were determined by spectrophotometric methods. Standard red winemaking process was applied to make the Bobal control wine. The rest of the wines were elaborated with oak chip contact at two dose levels (3 and 6 g/L) in different phases of the winemaking process: during alcoholic fermentation (AF), during malolactic fermentation (MLF), and in young wines. The phenolic composition, antioxidant activity, and chromatic characteristics of Bobal control wines were slightly but significantly modified by contact with the oak chips. Wines in contact with oak chips during malolactic fermentation showed a decrease in the concentration of resveratrol-monomer stilbenes, monomeric anthocyanins, and pyranoanthocyanins. In general, the concentration of total resveratrol is influenced by the dose level used, resulting in a 10% decrease when the dose level is 6 g/L compared to the 3 g/L dose.

In the last decade, the application of non-Saccharomyces yeasts in oenology as a natural tool to obtain wine diversification and higher quality has aroused great interest. In this work, three Metschnikowia pulcherrima strains, isolated from a vineyard, were characterised through the evaluation of their main oenological properties, antimicrobial activity, and specific enzymatic activities (β-glucosidase, β-lyase, polygalacturonase, and protease). The M. pulcherrima strains did not produce any inhibition against Saccharomyces cerevisiae, while they were able to exert an antimicrobial action against some unwanted bacteria and yeasts frequently present in grape must and potentially causing the alteration of wines. After this preliminary screening, M. pulcherrima AS3C1 has been selected to be used in the winemaking of red grape Vitis vinifera cv. Aglianico on a pilot scale. The effect of the sequential inoculation of M. pulcherrima AS3C1 with a commercial strain of S. cerevisiae was verified using for comparison a single inoculum with S. cerevisiae and a spontaneous fermentation. Our results showed a higher concentration of anthocyanins and catechins in wines obtained by the sequential inoculation of M. pulcherrima AS3C1 and S. cerevisiae. On the basis of the data obtained, M. pulcherrima AS3C1 possesses an enzymatic profile and some oenological properties that could contribute positively to the definition of the chemical composition of wines, suggesting its possible use for red winemaking processes.

The application of continuous fermentation with immobilized cells in brewing is a challenge because of problems with carrier selection and reactor design, which have economic impacts on the beer produced. Moreover, immobilization alters yeast physiology, which significantly affects beer flavor and aroma. Therefore, the aim of this study was to investigate the feasibility of a continuous fermentation system, consisting of a packed bed column bioreactor, containing lager brewing yeast, immobilized in alginate–chitosan microcapsules with a liquid core, in the primary beer fermentation. The results showed that the system entered in a stationary mode on the 3rd day and worked stably in this mode for 6 days. The “green” beer was taken at every 24 h at the output of the reactor and used for secondary fermentation with the yeast cells leaked from the capsules during the primary fermentation. The extract consumption, ethanol production, and pH change during primary and secondary fermentation were investigated. Some of the secondary yeast metabolites such as vicinal diketones, higher alcohols, esters, and aldehydes in “green” and final beers were determined and it was found that the flavor profile of the final beer was comparable to two industrially produced Bulgarian beers.

The production of beer, a beverage of global cultural and industrial importance, has a significant impact on the environment due to the use of natural resources and the emissions generated during the various stages of the production process. Therefore, this article examines the sustainability of beer production through a review of literature articles that have used Life Cycle Assessment (LCA) to assess its environmental impacts. A systematic literature review was conducted by selecting peer-reviewed articles published between 2001 and July 2024 using databases such as Scopus and Google Scholar. The search included studies analyzing different stages of the beer life cycle, from raw material production to packaging and distribution, using specific keywords related to LCA and brewing. The results showed that energy use and packaging are the two critical aspects identified in the review, which represent a significant part of the environmental footprint. However, it is important to note that the available studies on the subject are few and heterogeneous and they use different methodologies, impact categories, and functional units, which complicates the comparison and synthesis of results, limiting the ability to draw definitive conclusions. Recommendations were made to improve sustainability, including the adoption of more efficient technologies, the use of recycled materials for packaging, and the implementation of sustainable agricultural practices. These strategies could aim to significantly reduce the overall environmental impact of beer production.

In 2021, the tax on sweetened beverages was introduced in Poland. It is worth knowing how consumers, especially young people, perceive the tax and whether there are any changes in the consumption of such drinks. This cross-sectional study was conducted in 2022 and analyzed a convenience sample of young people’s attitudes towards the effectiveness of the tax as well as beverage consumption in the second year of the tax’s implementation. This study was conducted using a questionnaire method among 334 young people (167 school students and 167 university students). The vast majority of the study participants (84%) had heard about the introduction of the tax (there was no statistically significant difference between the school students’ and the university students’ knowledge). Of these, 90% knew that beverages with added sugar are taxed, but only 43% were conscious that beverages with sweeteners are also subject to the tax. Forty percent of those surveyed believed that the introduction of the tax could reduce beverage consumption, while 35% denied this possibility. The view that the tax would have a beneficial effect on reducing drink consumption was statistically significantly more frequently expressed by school students compared to university students (55% vs. 25%; p < 0.05). Of those who were aware of the tax, 31% declared they drank fewer beverages following its introduction, while 58% reported that they had not changed the amount they drank. About 33% of the respondents said they drank sweetened beverages several times a week. According to the study, as a result of the tax, almost one-third of surveyed young Poles reported drinking less beverages than before the tax.

The wine market is affected by the origin of wines, but the current wine traceability system has some limitations. The idea of geographical authenticity and quality has increased as one of the most important parameters influencing consumers’ preferences. Chemical parameters such as total polyphenolic content (TPC), alcohol and organic acid content (total acids, malic and tartaric acids), and antioxidant activity were observed in this work at 15 dry white wines of varieties Pinot blanc, Riesling, Sauvignon blanc, and Chardonnay, which originated from three different countries. FTIR and spectrophotometry methods (TPC and DPPH) were used and chemometric approaches such as ANOVA and PCA were selected as the most important for evaluation. In general, high levels of malic acid, TPC, and antioxidant activity were detected in Austrian wines. Pinot blanc, Chardonnay, and Sauvignon from the same producing region in Austria showed higher results. The higher overall acid concentration was a distinguishing feature of the Slovakian Sauvignon and Riesling varieties, particularly in the case of tartaric acid. Austrian samples showed significantly higher antioxidant activity compared to Hungarian Chardonnay (p = 0.002) and Sauvignon (p = 0.007), comparable to TPC. The application of statistical analysis was useful in demonstrating many discrepancies, particularly by application of the PCA method.

Beer, with its low pH, presence of hop acids, alcohol content, and limited nutrient availability, presents a hostile environment for most bacteria. However, Levilactobacillus brevis remains a significant spoilage organism in the brewing industry. This study examines the impact of high hydrostatic pressure (HHP) on the inactivation and sublethal injury of Lb. brevis KKP 3574 in beer and wort. The results indicate that applying HHP at 400 MPa for 5 min effectively inactivates Lb. brevis, achieving up to a 7 log CFU/mL reduction in bacterial counts in beer, with no detectable sublethal injuries in beer samples. In contrast, in 10% wort, a sublethal injury level of 1.1 log CFU/mL was observed following the same HHP treatment. Furthermore, this study reveals a differential response of Lb. brevis cells depending on their growth phase; cells in the logarithmic growth phase are more susceptible to HHP, showing greater reduction in viability compared to those in the stationary phase. The survival dynamics of sublethally injured cells during refrigerated storage are also explored, with no regeneration observed in beer samples treated at pressures of 400 MPa or higher. These findings underscore the potential of HHP as a robust method for enhancing the microbiological safety and stability of beer while minimizing the risk of spoilage due to sublethally injured bacterial cells. This study provides crucial insights into optimizing HHP parameters to ensure product quality in the brewing industry.

High-altitude and cold climate regions such as São Joaquim, in Santa Catarina, Brazil, a recent wine-growing region, are characterized by wines with pronounced acidity, ideal for sparkling wine production. The cultivars with potential for producing sparkling wines in this region were unknown. This research evaluates quality sparkling wines from Ribolla Gialla, Riesling Renano, Solaris, Sangiovese, Canaiolo Nero, Chardonnay, and Pinot Noir. The study considered the phenological, productive, and qualitative performance of these varieties in the 2017/2018 and 2018/2019 seasons. Ribolla Gialla, Riesling Renano, and Sangiovese, with later bud break and better productive aspects, are the best viticultural adaptations for the region. Riesling Renano maintains higher acidity. Sparkling wines from Solaris, Chardonnay, and Ribolla Gialla showed the most balanced chemical parameters. Sangiovese produced sparkling wine with the highest aroma intensity and toasted notes. Considering phenological, productive, and qualitative parameters, Riesling Renano, Ribolla Gialla, and Sangiovese are the most promising varieties for sparkling wine production in São Joaquim. Quality sparkling wines can be produced in this region using varieties different from those traditionally used in Brazil, enhancing the diversity of Brazilian viticulture.

To remove oxidizable polyphenolic compounds from wines, fining treatments with products of various origins are applied before or after fermentation. Seeking alternatives to the treatments with animal proteins or synthetic materials such as polyvinylpolypyrrolidone (PVPP), vegetal and mineral products are tested. One of these alternative agents is pea protein (P), which can be combined with chitosan (K), yeast cell walls (Y), active carbon (C), and/or Ca-bentonite (B). Aside from the proven polyphenol removal effect, these products can also have an impact on aroma. This research evaluates the effect of P and ternary combinations with P on the volatile compounds of aromatic wines from the Tămâioasă românească variety. Several variants of treatments with P and with ternary mixtures involving P were prepared in triplicate with a total dose of 20 g/hL of fining agent applied during the pre-fermentative phase. Volatile profiles were determined using a flash gas chromatograph with two short columns of different polarities. The chromatographic peak areas for the identified ethylic esters, acetates and terpenes were used to compare the fining treatment effects. To test the significant differences between experimental variants, the Analysis of Similarity (ANOSIM) was used. The influences of P used alone and PVPP used alone were both significantly different compared to control (untreated), but based on the dissimilarity index R, PVPP affected the volatile profile about twice as much as P, showing that pea protein is a good alternative for PVPP. The ethyl esters were especially reduced by PVPP, while P especially reduced the terpenes. From all the tested pea protein ternary agents, those containing bentonite (PCB and PYB) showed a significant reducing effect on all classes of compounds and therefore are not recommended. The combinations containing yeast cell walls, PCY and PKY, are the most interesting alternatives to both PVPP and P used independently, PCY being the least aggressive of all treatments on overall aroma, preserving well the aroma compounds of all determined classes, including terpenes.

Purple grape juice produces a significant amount of grape pomace (GP) as a by-product, which can be reused as a raw material in producing craft beers with bioactive properties. The objective of this study was to produce craft beers with the addition of GP during the fermentation process to evaluate the incorporation of bioactive compounds, aiming at using a by-product generated in the production of grape juice. Craft beer was produced, incorporating GP at concentrations of 1%, 5%, and 10% (w/w), and the physicochemical, technological, bioactive, and sensory properties were evaluated. The beers with the highest concentrations of GP (10% w/w) exhibited higher bioactive concentrations, including phenolic compounds (308 mg GAE/L), flavonoids (0.05 g of quercetin/L), anthocyanins (754.6 mg cyanidin-3-glucoside/L), and antioxidant capacities, as measured by DPPH (1878.2 µM Trolox/L), ABTS (4294.5 µM Trolox/L), and FRAP (844.7 mg ascorbic acid/L) methods. Adding GP promoted lower brightness (62.2) and intensified the a*, b*, and chroma parameters (18.0, 10.1, and 20.6, respectively), with the pigments of GP contributing to changes in the color parameters. However, increased sedimentation was observed under both conditions analyzed (4 °C and 25 °C), due to the higher presence of particulate matter from GP (3.4% and 3.7%, respectively). In general, for sensory analysis, while the knowledge of beneficial effects did not significantly change emotional responses, there were distinct emotional profiles associated with different beer samples. Utilizing GP for the bioactivation of beer is a positive approach to enhance its overall properties and an effective way to address issues related to the disposal of this by-product.

The objective of this study was to determine the chemical composition of sugarcane spirits and commercial Cachaças, comparing them with the limits established by national legislation and with studies conducted in previous periods. Previous studies have shown that 50% of the samples of this distillate were above the contaminant limits allowed by national legislation, constituting one of the main factors responsible for the low volume of exports. In this research, 531 Cachaça samples were analyzed in order to verify whether they complied with the limits of contaminants and volatile compounds required by Brazilian legislation. The results obtained indicate that Brazilian producers have adapted to the use of good manufacturing practices during the production process, ensuring the standardization of this distilled beverage and consequent compliance with legislation.

The aging ability of dry white wines has been increasingly recognized. The present work aimed to identify which sensory features drive their quality assessment by experienced tasters. Individuals assessed several sensory attributes, using dark tasting glasses. Wines originated from the grape varieties Alvarinho, Arinto, Sauvignon Blanc and Pinot Bianco with a wide range of ages. Basic physical–chemical analysis, browning (Abs 420 nm), elemental composition and a partial volatile fraction were also determined. The overall quality scores were a function of complexity and balance and were negatively influenced by the perception of faultiness. The aging process could be associated with a continuous sensory space characterized by a declining perception of freshness and an intensification in the mellowed flavors. Despite their age, wines were characterized by an austere perception caused by their acidity, saltiness, bitterness, smoothness and dryness. Nevertheless, quality scores were similar from the youngest to the oldest tasted wines (17 years old). The exception was a Sauvignon Blanc wine from a recent vintage that was judged as faulty due to the perception of earthiness. Overall, the tasted wines displayed an unexpected aging ability as demonstrated by the difference between the predicted and real wine ages. To improve the recognition of old wines, the metaphor “mellowed by age” is proposed to describe flavors resulting from beneficial aging instead of “oxidized by age”.

The “aromatic maturity” of winegrapes is not fully understood, particularly during the later stages of ripening. The contribution of grapes to wine aroma has historically been challenging to determine, given most aroma compounds originate from nonvolatile precursors. In this study, an analytical approach previously developed for red winegrapes was adapted to assess the “aroma potential” of Riesling from two vineyards in Essenheim and Durbach, Germany, during the 2022 vintage, by extracting and hydrolyzing aroma precursors in an anoxic model wine matrix. Following sensory and chemical analyses of the hydrolysates using flash profiling and gas chromatography, a multiple factor analysis revealed vineyard- and ripening-dependent changes to aroma, even after total soluble solids had plateaued. As samples matured, green apple and fresh/vegetal aromas were prominent among the Durbach hydrolysates, likely due to persistent concentrations of hexanol. Hydrolysates from both vineyards nonetheless developed more pronounced citrus fruit, tropical fruit, and floral aromas, reflecting increased concentrations of various norisoprenoids and terpenoids. Findings suggest delaying harvest past technological maturity could confer greater aromatic intensity and complexity. The analytical approach used here appears promising for future studies on other grape varieties and other factors that could influence aroma, such as viticultural practices and environmental conditions.

The production of high-quality aged marc spirits includes a minimum period of six months of ageing in oak barrels. Lastly, producers are interested in alternative botanical origin wood. The present study is aimed at investigating the influence of Greek oak (Quercus trojana) and Greek chestnut (Castanea sativa) compared with French (Quercus petraia) and American oak (Quercus alba) on the chemical composition and sensorial characteristics of aged tsipouro, produced from marc from the Black Muscat variety. Gas chromatography–olfactometry–mass spectrometry (GC–O–MS) was used to identify volatile compounds of the aged tsipouro. Also, colour and polyphenol measurements were made, and an organoleptic evaluation was performed by 16 trained tasters. The findings revealed rather similar results between the tsipouro made from different wood species, especially between Greek and French oaks, and relative differentiation for that of chestnut. All the aged distillates exhibited a pleasant and rich aromatic potential, dominated by floral and fruity terpene varietal aromas as well as wood-related volatiles. Chestnut, with a high phenolic potential, gives pleasant organoleptic effects over time and can be an alternative wood for ageing spirits. This research highlights the importance of wood selection in the tsipouro ageing process and enables the use of Greek wood species in the ageing of spirits.

White willow (Salix alba) is a medicinal plant traditionally used to treat pain and inflammation. The aims of this study were to produce polyphenol-rich herbal beverages from willow bark with different ethanol content, temperatures, and solvent pH and to explore neuroprotective potentials of willow polyphenols. The phenolic compounds quantified in the willow infusions were salicin, chlorogenic acid, epicatechin, p-salicylic acid, and p-coumaric acid; the former three compounds exhibited promising inhibitory potentials against acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) in molecular docking studies. Total phenol content and antioxidant activity were maximum when prepared with 50% ethanol-in-water at room temperature. Although aqueous infusions contained fewer total phenols than those extracted with 50% hydroalcoholic solutions, they enhanced the extraction of chlorogenic acid and salicin content, which may possess promising neuroprotective potentials. The addition of citric acids in hot water infusions led to a higher proportion of non-tannins and had a lighter appearance, which may result in less astringent mouthfeel and better consumer acceptance. Overall, the obtained results indicate that willow bark prepared with hot water and/or with addition of citric acids is rich in bioactive compounds with high antioxidant activity and possible neuroprotective activities in silico, which could serve as valuable ingredients for inclusion in functional beverages.

This study aimed to evaluate consumer perception and acceptance of non-alcoholic cocktails compared to their traditional alcoholic counterparts in a restaurant setting. Three popular cocktails—gintonic, mojito, and mule—and their non-alcoholic versions (NoLo) were assessed following a three × two experimental design. A total of 600 participants (approximately 100 per cocktail) participated at the Basque Culinary Center’s restaurant. Participants rated their liking of the cocktails using a nine-point hedonic scale and provided open-ended responses about the sensory characteristics and the consumption contexts or emotions evoked by the different cocktails. The results showed differences in the acceptance of the six cocktails, but no significant differences between the alcoholic and non-alcoholic versions, suggesting that NoLo alternatives were similarly well-received. Open-ended responses were analyzed using latent dirichlet allocation (LDA) to uncover latent topics, and Fisher’s exact test and correspondence analysis were used to identify differences in the mentioned topics per cocktail. Specific sensory attributes, emotions, and contexts were associated with each type of cocktail, but no differences were found between the alcoholic and non-alcoholic versions. These findings demonstrate the viability of non-alcoholic cocktails in real consumption settings, eliciting similar liking scores, sensory attributes, contexts, and emotions in consumers. This study also highlighted the potential of natural language processing techniques for analyzing open-ended questions.

Our investigation delves into the previously uncharted territory of cider composition from Norway. This study aimed to obtain an overview of the qualitative and quantitative compositions of general chemical parameters, polyphenols (individual and total expressed as gallic acids equivalents), selected esters, and selected C6-alcohols in ciders with the PDO label Cider from Hardanger. In total, 45 juice and cider samples from the fermentation process were collected from 10 cider producers in Hardanger in 2019, 2020, and 2021. Individual sugars, acids, ethanol, and 13 individual phenols were quantified using HPLC-UV/RI. Seven ethyl esters of fatty acids, four ethyl esters of branched fatty acids, ten acetate esters, two ethyl esters of hydroxycinnamic acids, and four C6-alcohols were quantified using HS-SPME-GC-MS. For samples of single cultivars (‘Aroma’, ‘Discovery’, ‘Gravenstein’, and ‘Summerred’), the sum of the measured individual polyphenols in the samples ranges, on average, from 79 to 289 mg L−1 (the lowest for ‘Summerred’ and highest for ‘Discovery’ and ‘Gravenstein’). Chlorogenic acid was the most abundant polyphenol in all samples. Ethyl butyrate, ethyl hexanoate, ethyl octanoate, ethyl decanoate, ethyl isobutyrate, ethyl 2-methylbutyrate, isoamyl acetate, and hexanol were present at concentrations above the odour threshold and contributed to the fruity flavour of the Cider from Hardanger.
