Late pruning modifies leaf to fruit ratio and shifts maturity period, affecting berry and wine composition in Vitis vinífera L. cv. ‘Malbec’ in Mendoza, Argentina
Bustos Morgani, Marianela; Fanzone, Martín Leandro; Perez Peña, Jorge Esteban; Sari, Santiago Eduardo; Gallo, Agustina Eugenia; Gómez Tournier, Mariana Belén; Prieto, Jorge Alejandro (Elsevier, 2023-04)Higher temperatures in recent years have advanced berry ripening and harvest date, decoupling berry sugar accumulation of anthocyanins final concentration and therefore reducing wine potential color. Late pruning is proposed ... -
Microwave-assisted extraction applied to Merlot grapes with contrasting maturity levels: effects on phenolic chemistry and wine color
Casassa, Luis Federico; Sari, Santiago Eduardo; Bolcato, Esteban Augusto; Fanzone, Martín Leandro (MDPI, 2019-01)Merlot grapes were harvested with three maturity levels (21.1, 23.1, and 25.1 Brix), and processed with or without the application of microwave-assisted extraction (MW). The detailed phenolic composition and color were ... -

(PAGEPress, 2022-11-25)The Bonarda variety has been used as a base for common red wines due to its contribution to color and low level of astringency as a consequence of its relative low tannin concentration. The use of MicrowaveAssisted Extraction ... -
Nucleotide sequence of key genes from the biosynthesis pathway of the major flavonoid in “Malbec” and “Cabernet Sauvignon”
Blanco, Maria Evangelina; Gomez Talquenca, Gonzalo; Casassa, Luis Federico; Sari, Santiago Eduardo; Torres, Maria Del Rocio; Ulanovsky, Silvia Matilde; Fanzone, Martín Leandro (2015)In red wines, important sensory attributes such as color and astringency are the result of the accumulation of anthocyanins, which are located in the berry skin (and in the pulp of teinturier cultivars). Each cultivar has ... -
