Obtaining new varieties derived from Monastrell for the preparation of low alcoholic wines

Abstract

The main challenge faced by viticulture is to improve the quality of the wines, adapting them to the new consumer demands that demand wines with lower alcohol content and greater freshness. In the last 30 years, a clear modification has been observed in the composition of the grape due to climate change, showing a higher sugar content due to an excess of maturity, giving rise to wines with a higher alcohol content, less organic acids, a higher pH high, and a lower anthocyanin content and, therefore, lower color (van Leeuwen and Destrac-Irvine, 2017).

There are different strategies to achieve wines with a lower alcohol content, one of them would be to obtain new varieties that can adapt to harsher growing conditions than the current ones and that are capable of producing quality grapes and wines. In 1997, a program of crossings directed from the Monastrell variety began at IMIDA. At present, a new line is being started in which the selection of hybrids that accumulate few sugars in the pulp and therefore suitable for the production of wines with a low alcohol content has been carried out.

In 2017, 6 red hybrids of “low alcohol content” were selected from crosses between Monastrell, Syrah and Cabernet Sauvignon, of which 20 strains of each were planted. This year for the first time they have entered production and have been able to be elaborated. The grapes were harvested on August 25 with a ºBrix between 21 and 23, and the CI of the wines obtained at the end of alcoholic fermentation is between 40 and 62 color points. The results, although still preliminary, may be very promising for the future of viticulture.

A look back at 20 years of exploring the future of the vines and wines sector

What if, in 25 years, most wines were dealcoholized and flavored ? What if vines were only cultivated to combat erosion, store carbon, and provide anthocyanins…? What if climate change completely changed the list of vine varieties cultivable for wine production in France? What if food stores had completely disappeared in favor of virtual platforms? And if… because the long-term future is not predetermined and therefore not knowable, because the future is open to several possibilities, because the future does not emerge from nothing but from the present which conceals heavy trends and weak signals, prospective approaches make it possible to consider the room for maneuver that actors have to promote the advent of a future, which we can hope to be chosen, at least in part.

Using open source software in viticultural research

Many high quality Open Source scientific applications have been available for a long time. Some of them have proved to be particularly useful for carrying out the usual activities involved in viticultural research projects, such as statistical analyses (including spatial analyses), GIS work, database management (possibly integrated with statistical and spatial analysis) and even “low-level” often highly time-consuming activities (e.g. repetitive task on text files).

Climate change, regional adaptation necessities and impact on grape and wine composition – an integrated view on a moving target

Grapevines are cultivated on 6 out of 7 continents, roughly between latitudes 4° and 56° in the Northern Hemisphere and between 6° and 42° in the Southern Hemisphere across a large diversity of climates (oceanic, warm oceanic, transition temperate, continental, cold continental, Mediterranean, subtropical, attenuated tropical, and arid climates).

The concept of « terroir »: what does that mean ? What is it useful for ? French young adults perception

Far from complicated discussions on the relevant way to define « terroir », this article deals with the social perception that French young adults (aged from 18 to 30) have of this concept and the way it can help them to become wine consumers.
