“…The highest pH values were found in the 'Felicia', the average of the three evaluated vintages was 3.61 to 840 m and 3.52 to 1250 m. 'Calardis Blanc' showed intermediate pH values, on average 3.48 at 840 m and 3.36 at 1250 m. And 'Helios' had the lowest pH values in 2020 and 2021 vintages, on average the values obtained in this experiment were 3.37 at 840 m and 3.33 at 1250 m. In general, regardless of the variety, the grapes produced in the lower altitude vineyard had higher pH values (Table 4). The pH values obtained in this experiment were also higher than those obtained in Sauvignon Blanc grapes by Marcon et al (2020) and in Chardonnay by Panceri et al (2018) in high altitude regions. The ideal pH for producing quality wines is between 3.10 and 3.50 and values outside this range can affect the wine final quality (JACKSON, 2010).…”

Downy mildew (Plamopora viticola) is one of the major problems to produce wine grapes in Brazil, a main cause of yield losses in the Southern region of the country. An alternative to the use of pesticides is the use of resistant varieties (PIWI): wine grapes combining high oenological potential and resistance to diseases. The goal of this work was to assess the vegetative and productive performance and maturation of three PIWI varieties (‘Felicia’, ‘Calardis Blanc’ and ‘Helios’) produced at altitudes of 840m and 1250m in the 2020, 2021 and 2022 vintages. The study is focused on four phenological stages: budbreak (BBCH 7), full bloom (BBCH 65), veraison (BBCH 81) and maturity/harvest (BBCH 89). The criteria for measuring the productive performance were, the number of clusters, average cluster weight, production per plant, yield and Ravaz index. As parameters for technological and phenolic maturation, pH, soluble solids, total acidity and total polyphenols were evaluated. The budbreak occurred at the end of August until the second fortnight of September, the flowering occurred in the second week of October, the veraison occurred during the month of December, and the maturity/harvest occurred from the second fortnight of January until the beginning of February. The earliest budbreak occurred with ‘Felicia’ in the vineyard at 1250m and the latest occurred with ‘Calardis Blanc’. Regardless of the vineyard altitude, there was practically no difference in the flowering date between varieties and the vineyards altitude, the veraison and the maturity/harvest occurred earlier in the vineyard at 840m. The varieties produced at 840 m had a shorter cycle and proved to be more productive when compared to those produced at 1250 m. The studied varieties showed good phenological adaptation, high yield and maturation indices suitable for the production of quality still and sparkling white wines at both altitudes. From the results obtained, ‘Felicia’ and ‘Calardis Blanc’ seem to be the most promising varieties for cultivation in both altitude ranges.

“…There are several systems used to support the vine, and the choice must be based on the edaphoclimatic conditions, the topography of the area, economic aspect and profitability, rootstock/scion ratio, and production objective. Rustic or fine grapes grown in systems such as trellis and Y usually have higher fruit yield per vine and yield due to the greater vegetative canopy (Marcon et al 2020). Although these systems enhance the vigor of the canopy, they can reduce the quality of the berries (Leão and Chaves 2021).…”

Training systems improved agronomic characteristics and quality of ‘Niagara Rosada’ table grapes

et al. 2023

Vines are highly responsive to agricultural management techniques, such as training systems. Three training systems, i.e., conventional, high, and double training, for the 'Niagara Rosada' vine were studied considering aspects related to the yield, physicochemical, and antioxidant characteristics of the grapes. The experiment was carried out during two seasons (2017 and 2018), and the vines grafted on IAC 572 Jales. The training systems did not influence the fruit production per vine and yield of the 'Niagara Rosada' table grape, but some improvements were observed, such as a greater number of berries per bunch in vines managed in the conventional training systems and a higher fresh mass of berries when cultivated in the high and double training systems. Grapes from the double training system had higher soluble solids contents, an important sensorial characteristic in table grapes. The high training system, in turn, provided 'Niagara Rosada' table grapes with a greater content of bioactive compounds (e.g., phenolic compounds, flavonoids, and anthocyanins) and antioxidant activity.

Research insights arising from the sciences of Viticulture, Enology and Vitivinicultural Economy are crucial for responding to an everincreasing set of challenges - such as climate change, environmental issues and a global and more competitive market - faced by the players in the vitivinicultural sector. In this context, the scientific journals play a key role in spreading the knowledge acquired worldwide and contributing to the generation of new ideas and new research lines. The Ciência e Técnica Vitivinícola is one of the oldest and few scientific journals specifically devoted to these three branches of science. In 2020, twelve articles from several international research teams were published, covering a wide range of current topics, including: sustainability of viticulture and winemaking; modelling of climate impact on wine production; control of pests and diseases; management and adaptability of grapevine varieties; quality and differentiation of wine based on minority grapevine varieties, native yeasts from grapevine and winemaking technologies; wine authenticity and traceability; botrytized wines; human resource management in small wine companies.
