Contribution of soil for tipifiyng wines in four geographical indications at Serra Gaúcha, Brazil

Abstract

Brazil has a recent history on geographical indications and product regulation for high quality wines. The first geographic indication implemented was the Vale dos Vinhedos Indication of Procedence (IP), within the wine production zone named Serra Gaúcha, northeast of State Rio Grande do Sul. During the last decade, the Vale dos Vinhedos ascended to the category of Denomination of Origin (DO) and three new IPs were delimited in the same region: Pinto Bandeira, Altos Montes and Monte Belo. It is known that production of high quality wines depends on the interaction of environmental factors and human activities. At local scale, soil plays important role since several factors affecting grape and wine quality are related to soil properties. The objective of this study was to evaluate potential contributions of soil to differentiate between wines produced in each of the four geographic indications at Serra Gaúcha.

Material used included a digitized soil map in scale 1:50.000 of Serra Gaúcha and digital georeferenced boundaries of the geographic indications. Spatial analysis was done on ArcGIS software. A total of 23 soil mapping units were found. Results showed that both the DO Vale dos Vinhedos (15 mapping units) and IP Pinto Bandeira (13 mapping units) have a relative predominance of Inceptisols, with low natural fertility and low organic matter content. The IP Monte Belo (9 mapping units) presents near 50% of Ultisols, with low natural fertility and medium to high levels of organic matter. In the IP Altos Montes (11 mapping units) most soils are Inceptisols with low natural fertility and low organic matter content, as well as Oxisols with low natural fertility and medium level of organic matter. Due to the observed spatial variability, soil information can help to tipify and differentiate wines produced in each of the four geographical indications at Serra Gaúcha.

A NEW SPECIFIC LINEAGE OF OENOCOCCUS OENI IN COGNAC APPELLATION WINES

Oenococcus oeni is the main lactic acid bacteria (LAB) species which conducts the malolactic fermentation (MLF) in wine. During MLF, O. oeni converts malic acid into lactic acid, which modulates wine aroma composition leading to better balanced organoleptic properties. O. oeni is a highly specialized species only detected in environments containing alcohol such as wine, cider or kombucha. Genome analysis of more than 240 strains showed that they form at least 4 main phylogenetic lineages and several sublineages, which are associated with different beverages or types of wines.

Aroma profile of Tempranillo tropical red wines from different seasons in the São Francisco valley, northeast of Brazil

Aromatic characteristics of wines are strongly influenced by agronomical and enological factors, depending of the climate, cultivar and winemaking process. Tropical wines are a new concept of vitiviniculture that is being developped in the Northeast of Brazil since the 80’s, located between 8-9º latitude of the South Hemisphere, where the second most important cultivar used for reds is Tempranillo. In this condition, vines produce grapes and enologists elaborate wines twice a year, because high temperatures, solar radiation and water availability for irrigation.

SENSORY PROPERTIES IMPORTANT TO AUSTRALIAN FINE WINE CONSUMER SEGMENT PERCEPTION OF CHARDONNAY WINE COMPLEXITY AND PREFERENCE

Wine complexity is considered a multidimensional yet equivocal sensory percept. This project uncovered sensory attributes Australian Chardonnay wine consumers associate with Chardonnay wine complexity
and correlations between expert and consumer perceived wine complexity and preference. A
wine consumer test examined 6 Australian Chardonnay wines of three complexity levels designated low (LC1&2), medium (MC1&2), and high (HC1&2) by an expert panel (n = 8) using a benchtop sensory task. Consumers (n = 81) rated their perceived liking using a 9-point hedonic scale; wine complexity with a 5-point scale anchored “low”, “low-medium”, “medium”, “medium-high”, and “high” and lastly, profiled the wines using Rate-All-That-Apply (RATA). Psychographic segmentation with the Fine Wine Instrument
(FWI) generated three segments; Wine Enthusiasts (WE n=29), Aspirants (ASP n=40) and No- Frills (NF n=12).
