“…This prestigious recognition catapulted Georgia into the spotlight of the global wine market, particularly for its distinctive amber wines. These wines, made from white grapes fermented together with their skins and sometimes stems in the traditional qvevri, became a hallmark of Georgia's winemaking identity, representing the country's unique contribution to the world of wine [38,39].…”

Over the past few decades, there has been a notable paradigm shift worldwide, affecting people’s preferences and decisions regarding both food and beverage options. These factors have sparked a newfound fascination among winemakers, wine enthusiasts, and consumers alike, as they explore the notion of reconnecting with a bygone era and embracing a lifestyle reminiscent of the past. “Orange” wine, a product derived from white grapes, encapsulates the intriguing allure of ancient winemaking methods that trace their roots back to Georgia. The method enables an elevated presence of phenolic compounds, which can have a favorable influence on the sensory characteristics of the wines or their behavior during oxidative processes. Given the scarcity of widespread knowledge, this overview aims to provide a comprehensive understanding of the historical evolution of winemaking and its various transformations over the years. It delves into the intricacies of winemaking technology, particularly focusing on the unique utilization of qvevri vessels. In addition to traditional sources, this review examines the influence of winemaking technology and the utilization of special vessels on the characteristics of “orange” wines. It explores the unique traits that develop in these wines as a result of prolonged maceration. By considering the impact of these factors, the review offers insights into the distinct qualities and attributes that emerge in “orange” wines during the winemaking process.

“…The antiradical activity was evaluated by using the stable radical DPPH (1,1-diphenyl-2-picrylhydrazyl) test, as described in Ieri et al [39]. In detail, millet phenolic extracts were added in a 1:1 amount to an ethanolic solution of DPPH (0.04 mg/mL).…”

Proso millet has been proposed as an effective anti-diabetic food thanks to the combined action of polyphenols and starch. This study aimed to characterize the chemical composition of twenty-five accessions, in order to enhance this cereal as an alternative to available starch for food applications or to propose new food ingredients with health benefits. Proso millet contained a high percentage of starch, reaching values of 58.51%. The amylose content showed high variability, with values ranging from 1.36 to 42.70%, and significantly higher values were recorded for the white accessions than for the colored ones. High-resistant starch content (13.41–26.07%) was also found. The HPLC-MS analysis showed the same phenolic pattern in all the samples. Cinnamic acids are the most abundant compounds and significant differences in their total content were found (0.69 to 1.35 mg/g DW), while flavonoids were only detected in trace amounts. Statistical results showed significantly higher antiradical activity in the colored accessions than in the white ones.

“…Thus, it can be assumed that the territory of Georgia could easily be a home for ancient tribes involved in cattle domestication. Nevertheless, while this country's agriculture illuminates ancient traditions of winemaking(Ieri et al 2021), honey production(Kvavadze et al 2007), and wheat cultivation(Gogniashvili et al 2021), there is no clear scienti c information on ancient animal husbandry traditions, which, as we assume, should have existed even from ancient times in Georgia. However, a broad distribution of GMB individuals across T, Q, and I (particularly in light of the age estimates of these haplogroups), and a fairly large number of its SNGTs present, with some falling even outside the known haplogroup-speci c evolutionary lineages of B. taurus, raise collectively many important questions about the origin and evolution of this local breed.…”

An in-depth understanding of the biodiversity of Bos taurus is highly important to tackling global food security challenges partially via deciphering and preserving local breeds that demonstrate their potential to adapt to the growing global warming worldwide. In this study, we elucidate the population structures and mechanisms of evolutionary divergence of the Georgian Mountain Breed (GMB) of cow and its genetically most closely related conspecifics worldwide. We performed the sequencing and evolutionary analyses of the specific mitochondrial DNA (mtDNA) region involving cytb, two tRNAs-encoding genetic loci, and the D-loop of the GMB populations from the Khevsureti and Adjara regions of Georgia. A large panel of different evolutionary algorithms, implemented in the MEGA11 and DnaSP software packages, were applied in these analyses. A total of 25 haplotypes were determined among 82 individuals of GMB, belonging predominantly to the haplogroups T (T3, T1, T2, T4) or Q (Q1). 10 hitherto unique haplotypes, exhibited by singletons (SNGTs), could be also determined in the GMB populations from the above regions. In the maximum likelihood evolutionary analysis, a specific SNGT appeared to be most closely related to the Bos indicus sub-haplogroup I1a. The haplotype diversity (0.997), nucleotide diversity (0.00636), and the overall mean distance within their populations (0.01) were higher for GMB as compared to these estimates (0.930, 0.00482, and 0.00) calculated for its genetically most closely related conspecifics respectively. It is suggested that the evolution of the GMB populations has been driven via introgression, as well as by parallel and/or possible convergent evolution.
