Armenia: historical origin of domesticated grapevine

Abstract

The Armenian Highlands are located on the northern border of Western Asia and stretch up to the Caucasus from the north. Throughout human history, the country has played an important role in connecting the civilizations of Europe and the Near East. A recent large-scale study about the dual domestication origin and evolution of grapes approved that in the Armenian Highlands human and grapevine stories are interlaced through centuries and roots of grapevine domestication are found deep in the Pleistocene, ending 11.5 thousand years ago. Until recently very little was known about the real magnitude of grape germplasm in Armenia. To address the gap in 2017, a nationwide program was launched to collect, conserve, and thoroughly characterize Armenian grapevine germplasm. Obtained results indicated that high genetic and morphological diversity as a source of novel alleles and genotypes is still safeguard in Armenia. A combination of genomic data, nuclear microsatellite markers and ampelography proved useful to determine the identity of collected samples recovered from old vineyards and home gardens, to analyze genetic relationships among two subspecies of Vitis vinifera, to demonstrated existence of gene flow between the wild and cultivated grapevines through overlaps and presence of admixed ancestry values.

Where the sky is no limit — The transformation of wine marketing through text-to-video generation AI model

The introduction of ai-driven tools in digital content creation represents a significant shift in the landscape of marketing, particularly for industries reliant on rich visual storytelling such as the wine sector. The development of ai models like openai’s sora, runway’s gen-2 or google’s lumiere, which can generate realistic video content from textual descriptions, offers promising new avenues for enhancing brand narrative and consumer engagement. This research explores the potential of text-to-video (t2v) ai models to revolutionize wine marketing by creating dynamic, engaging content that captures the essence of vineyards and their products without the need for traditional video production processes.

Carbon footprint in Austrian viticulture – Evaluation of the main polluters and possible solutions in entire the production chain

The sustainability certification ‘nachhaltig austria’ (www.sustainableaustria.com) has been offered to austrian wineries in an online version for 10 years and over 25% of the austrian wine-growing area is now certified. Since the 2022 harvest, ‘nachhaltig austria’ has automatically calculated the carbon footprint for each winery, per hectare of vineyard, per litre of bulk wine and per 0.75-litre bottle (poelz, w. And rosner, f.g. 2023). In last year’s publications and numerous presentations at national and international level, topics such as refilling glass bottles, lightweight glass bottles, renewable energy, … Etc.
