In a global warming scenario, it arouses as a technological solution since it prevents berry overheating and sunburn. Canopy management practices manipulate leaf\u2010to\u2010fruit ratios, affecting berry and wine composition. We aimed to evaluate the phenolic and sensory profiles of Malbec wines from single high\u2010wire trellised vineyards in a hot region in Mendoza (Argentina) and to assess the effect of varying leaf\u2010to\u2010fruit ratios on these attributes. We manipulated leaf\u2010to\u2010fruit ratios by varying shoot trimming (experiment 1: 0.45\u2009m, 0.80\u2009m, and untrimmed) and winter pruning severity (experiment 2: 16, 24, 32, and &gt;32 countable buds per meter). We characterized wine attributes by a descriptive analysis, color by the CIELAB space, and global phenolics compounds and anthocyanins by high\u2010performance liquid chromatography with diode array detection.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>We found that wines where shoots were trimmed to 0.80\u2009m or left untrimmed had similar and greater intensity of color, violet hue, astringency, and alcohol and a richer aroma profile than wines where shoots were trimmed to 0.45\u2009m. Meanwhile, wines from 16 and &gt;32 buds\/m treatments (the latter simulating a box pruning) were similar to each other and had higher color intensity, violet hue, acidity, alcohol, and astringency and a more complex aroma profile than the other pruning treatments.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSIONS<\/jats:title><jats:p>The best quality wines were achieved by leaving 16 or &gt;32 buds\/m and by trimming shoots to 0.80\u2009m or leaving them untrimmed. The modulation of cultural practices in sprawling canopies offers the potential to produce wines with different styles in hot regions. \u00a9 2020 Society of Chemical Industry<\/jats:p><\/jats:sec>","DOI":"10.1002\/jsfa.10760","type":"journal-article","created":{"date-parts":[[2020,8,24]],"date-time":"2020-08-24T23:56:44Z","timestamp":1598313404000},"page":"1467-1478","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Effect of <scp>leaf\u2010to\u2010fruit<\/scp> ratios on phenolic and sensory profiles of Malbec wines from single <scp>high\u2010wire\u2010trellised<\/scp> vineyards"],"prefix":"10.1002","volume":"101","author":[{"given":"Gast\u00f3n E","family":"Ahumada","sequence":"first","affiliation":[{"name":"Trapiche Winery  Maip\u00fa Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anibal","family":"Catania","sequence":"additional","affiliation":[{"name":"Estaci\u00f3n Experimental Agropecuaria Mendoza Instituto Nacional de Tecnolog\u00eda Agropecuaria  Luj\u00e1n de Cuyo Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin L","family":"Fanzone","sequence":"additional","affiliation":[{"name":"Estaci\u00f3n Experimental Agropecuaria Mendoza Instituto Nacional de Tecnolog\u00eda Agropecuaria  Luj\u00e1n de Cuyo Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcelo J","family":"Belmonte","sequence":"additional","affiliation":[{"name":"Trapiche Winery  Maip\u00fa Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carla V","family":"Giordano","sequence":"additional","affiliation":[{"name":"Instituto Argentino de Investigaciones en Zonas \u00c1ridas, CONICET\u2013UNCuyo\u2013Gobierno de Mendoza  Mendoza Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3014-7129","authenticated-orcid":false,"given":"Carina V","family":"Gonz\u00e1lez","sequence":"additional","affiliation":[{"name":"Instituto de Biolog\u00eda Agr\u00edcola de Mendoza, FCA UNCuyo\u2013CONICET  Luj\u00e1n de Cuyo Mendoza Argentina"},{"name":"Facultad de Ciencias Exactas y Naturales Universidad Nacional de Cuyo  Mendoza Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,9,16]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"crossref","first-page":"339","DOI":"10.5344\/ajev.2009.60.3.339","article-title":"Long\u2010term performance of Barbera grown under different training systems and within\u2010row vine spacings","volume":"60","author":"Bernizzoni F","year":"2009","journal-title":"Am J Enol Vitic"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.5344\/ajev.2014.14037"},{"key":"e_1_2_7_4_1","doi-asserted-by":"crossref","first-page":"116","DOI":"10.5344\/ajev.1995.46.1.116","article-title":"Integrated evolution of trellis training systems and machines to improve grape quality and vintage quality of mechanized Italian vineyards","volume":"46","author":"Intrieri C","year":"1995","journal-title":"Am J Enol Vitic"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1755-0238.2003.tb00257.x"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.5344\/ajev.2005.56.2.170"},{"key":"e_1_2_7_7_1","first-page":"509","volume-title":"The Science of Grapevines: Anatomy and Physiology","author":"Keller Markus","year":"2015"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.5344\/ajev.2009.60.3.251"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.5344\/ajev.1985.36.3.230"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.3390\/agronomy9090514"},{"key":"e_1_2_7_11_1","unstructured":"OIV.
