Chemical characteristics of grapes cv. Syrah (Vitis vinifera L.) grown in the tropical semiarid region of Brazil (Pernambuco state): influence of rootstock and harvest season. Repositório Alice
OLIVEIRA, J. B. de; EGIPTO, R.; LAUREANO, O.; DE CASTRO, R.; PEREIRA, G. E.; RICARDO-DA-SILVA, J. M..
BACKGROUND: Obtaining two or more successive annual vintages from the same vineyard is characteristic of regions with a tropical climate, such as the Submédio of the São Francisco Valley, Brazil. The present study aimed to characterize the chemical composition of grapes in four production cycles (i.e. two calendar years) when considering the interaction between cv. Syrah and two rootstocks. For a broad characterization, two methodologies for the extraction of phenolic compounds were used, as well as different methods of analysis. RESULTS: The results obtained showed that there was an influence of rootstock and harvest season. Grapes from vines grafted onto IAC 313 contained higher concentrations of total condensed tannins (skins) and flavanols than grapes...

Chemical composition and sensory profile of Syrah wines from semiaridtropical Brazil?Rootstock and harvest season effects. Repositório Alice
OLIVEIRA, J. B. de; EGIPTO, R.; LAUREANO, O.; DE CASTRO, R.; PEREIRA, G. E.; RICARDO-DA-SILVA, J. M..
This study aims to characterise the chemical compositions and sensorial profiles of wines made with Syrahgrapes over two harvest seasons (first and second semester), over in different calendar years, from vines on twodifferent rootstocks (1103P and IAC 313). Wine chemical composition and sensory profile were influenced byboth rootstock and harvest season. Syrah wines on IAC 313 were favoured with higher concentrations of, pet-unidin 3-O-acetylglucoside (3.7 mg/L), malvidin 3-O-acetylglucoside (17.8 mg/L), malvidin 3-O-coumar-ylglucoside (4.4 mg/L), petunidin 3-O-coumarylglucoside (2.0 mg/L), peonidin 3-O-coumarylglucoside (1.4 mg/L), monomericflavanols (23.6 mg/L), oligomeric tannins (183.0 mg/L), total condensed tannins (1037.7 mg/L),dimer B1 (9.8 mg/L),...

Aim: This study is part of a CYTED (Ibero-American Program for Science, Technology and Development) project on vitivinicultural zoning. The objective was to characterize the effect of viticultural climate on red and white wine typicity in the macro Ibero-American viticultural region. Methods and results: The climate of 46 grape-growing regions in 6 Ibero-American countries (Argentina, Bolivia, Brazil, Chile, Spain and Portugal) was characterized using the three viticultural climate index of the Geoviticulture MCC System: the Heliothermal index HI, the Cool Night index CI and the Dryness index DI. The main sensory characteristics frequently observed in representative red and white wines of each of these regions were described by enology experts in the...
