Geographical origin, use of traditional varieties and ancestral viticulture/oenology practices characterize wines classified as Historical Wines of Portugal (HWP). This post reports a study that identifies the authenticity attributes consumers associate with this classification and assesses the relative strength of associations. Compared to Aspirational Explorers, wine connoisseurs emerged as Heritage Gatekeepers, associating origin, cultural heritage, quality, production and at-home consumption more strongly with HWP, and tradition, wine age and out-of-home consumption less strongly. Market recognition of HWP as a novel and distinctive table wine classification, with well-defined and unique attributes, is thus likely to depend on consumers’ general wine knowledge. Related promotional activities targeting wine novices should first focus on educating them on HWP classification, whereas those directed at savvier consumers should emphasize wine authenticity cues instead.
Understanding ‘Malbec’ clonal diversity through genomics and history
Malbec is a cultivar that is well-appreciated for the elaboration of red wine. It originated in Southwestern France and was introduced in Argentina during the 1850s. In order to study the clonal genetic diversity of Malbec grapevines, the authors of this post generated whole-genome resequencing data for four accessions with different clonal propagation records. The results show the usefulness of this approach for the study of the scarce intra-cultivar genetic diversity in grapevines. We also provide evidence on how human actions might have driven the accumulation of different somatic mutations, ultimately shaping the Malbec genetic diversity pattern.
Domestication of wild grapevines is still active
Global viticulture has evolved following market trends, causing loss of cultivar diversity and traditional practices. In Montenegro, modern viticulture co-exists with a traditional viticulture that still maintains ancient practices and exploits local cultivars. As a result, this region provides a unique opportunity to explore processes increasing genetic diversity. This post reports the results of a study carried out to evaluate the diversity of Montenegrin grapevines and the processes involved in their diversification. Analyses of genetic structure unveiled several putative proto-varieties, likely representing the first steps involved in the generation of new cultivars or even secondary domestication events.
Assessment of Digital Surface Models using Backpack-Mounted Systems and Drone Techniques to Characterize Ancient Underground Cellars in the Duero Basin
The use of new technologies of capture like MMS or UAV reduce the cost and time of registration and allow the improvement of knowledge of the status of this kind of high value heritage areas.
2019 In Review
This is the last post of 2019. The second year of Science & Wine existence, time for a brief reflection. This was a great year!
Post Nº 100
This is the post number 100. One hundred of weekends that I spend writing, reading, illustrating, editing and publishing the posts. The time that I spent do it is just part of the time I stole to the family, special to my youngest daughter, so today I decided to involve her in this project. The illustration is her authorship.
Monthly Assignment Challenge – May
Yes, Paula Silva, I would be honoured to continue your post on ‘The science behind the wine label’. However, I have to admit that your solemn title left me a bit nervous. After all, I am not a scientist, and even as a researcher, I consider myself a novice in academic writing.
Professional highlights in wine area
Today ended the “Mostra da Universidade do Porto” that is an annual exhibition where the University of Porto schools promote their educational offer. The most repeated question made by high school students was “What can I do with that degree?”. I always answer, “All that you want”. I really believe it! Someone with cognitive and hard work capacities, can do anything with the tools acquire during the course. Joining creativity and courage, then are congregated the conditions to a brilliant career. Of course, that a personal career also depends in the networks that each one can establish.
The terroir of Port wine: Two hundred and sixty years of history
I am very proud to be the responsible for the first review paper (The terroir of Port wine: Two hundred and sixty years of history) that provides an extensive insight regarding different aspects that influence the quality and uniqueness of Port wine.
