Viticulture and Winemaking Under Climate Change
agronomy Editorial Viticulture and Winemaking under Climate Change Helder Fraga Centre for the Research and Technology of Agro-Environmental and Biological Sciences, CITAB, Universidade de Trás-os-Montes e Alto Douro, UTAD, 5000-801 Vila Real, Portugal; [email protected]; Tel.: +351-259-350-000 Received: 12 November 2019; Accepted: 19 November 2019; Published: 21 November 2019 Abstract: The importance of viticulture and the winemaking socio-economic sector is acknowledged worldwide. The most renowned winemaking regions show very specific environmental characteristics, where climate usually plays a central role. Considering the strong influence of weather and climatic factors on grapevine yields and berry quality attributes, climate change may indeed significantly impact this crop. Recent-past trends already point to a pronounced increase in the growing season mean temperatures, as well as changes in the precipitation regimes, which has been influencing wine typicity across some of the most renowned winemaking regions worldwide. Moreover, several climate scenarios give evidence of enhanced stress conditions for grapevine growth until the end of the century. Although grapevines have a high resilience, the clear evidence for significant climate change in the upcoming decades urges adaptation and mitigation measures to be taken by the sector stakeholders. To provide hints on the abovementioned issues, we have edited a special issue entitled: “Viticulture and Winemaking under Climate Change”. Contributions from different fields were considered, including crop and climate modeling, and potential adaptation measures against these threats. The current special issue allows the expansion of the scientific knowledge of these particular fields of research, also providing a path for future research. -

Microbial and Chemical Analysis of Non-Saccharomyces Yeasts from Chambourcin Hybrid Grapes for Potential Use in Winemaking
fermentation Article Microbial and Chemical Analysis of Non-Saccharomyces Yeasts from Chambourcin Hybrid Grapes for Potential Use in Winemaking Chun Tang Feng, Xue Du and Josephine Wee * Department of Food Science, The Pennsylvania State University, Rodney A. Erickson Food Science Building, State College, PA 16803, USA; [email protected] (C.T.F.); [email protected] (X.D.) * Correspondence: [email protected]; Tel.: +1-814-863-2956 Abstract: Native microorganisms present on grapes can influence final wine quality. Chambourcin is the most abundant hybrid grape grown in Pennsylvania and is more resistant to cold temperatures and fungal diseases compared to Vitis vinifera. Here, non-Saccharomyces yeasts were isolated from spontaneously fermenting Chambourcin must from three regional vineyards. Using cultured-based methods and ITS sequencing, Hanseniaspora and Pichia spp. were the most dominant genus out of 29 fungal species identified. Five strains of Hanseniaspora uvarum, H. opuntiae, Pichia kluyveri, P. kudriavzevii, and Aureobasidium pullulans were characterized for the ability to tolerate sulfite and ethanol. Hanseniaspora opuntiae PSWCC64 and P. kudriavzevii PSWCC102 can tolerate 8–10% ethanol and were able to utilize 60–80% sugars during fermentation. Laboratory scale fermentations of candidate strain into sterile Chambourcin juice allowed for analyzing compounds associated with wine flavor. Nine nonvolatile compounds were conserved in inoculated fermentations. In contrast, Hanseniaspora strains PSWCC64 and PSWCC70 were positively correlated with 2-heptanol and ionone associated to fruity and floral odor and P. kudriazevii PSWCC102 was positively correlated with a Citation: Feng, C.T.; Du, X.; Wee, J.

Late Harvest
TASTING NOTES LATE HARVEST DESCRIPTION 2017 The Tokaj legend has grown and grown in its four-hundred years of history; but it was not until 1630, when the greatness of Oremus vineyard was first spoken of. Today, it is the one with greatest universal acclaim. The Tokaj region lies within the range of mountains in Northeast Hungary. Oremus winery is located at the geographical heart of this region. At harvest, bunches are picked several times a day but. Only those containing at least 50% of botrytis grapes, are later pressed, giving the noble rot a leading role. Late Harvest is an interesting coupage of different grape varieties producing an exceptionally well-balanced wine. Fermentation takes place in new Hungarian oak barrels (136- litre “Gönc” and 220-litre “Szerednye”) for 30 days and stops naturally when alcohol level reaches 12 %. Then, the wine ages in Hungarian oak for six months and sits in bottle for a 15-month ageing period. Late Harvest is a harmonious, fresh, silky wine. It is very versatile, providing a new experience in each sip. GENERAL INFORMATION Alcohol by volume - 11 % Sugar - 119 g/l Acidity - 9 g/l Variety - Furmint, Hárslevelü, Zéta and Sárgamuskotály Average age of vineyard - 20 years Vineyard surface area - 91 ha Planting density - 5,660 plants/ha Altitude - 200 m Yield - 1,300 kg/ha Harvest - 100% Hand-picked in 2-3 rounds from late September to early November 2017 VINEYARD CYCLE After the coldest January of the past decade, spring and summer brought average temperatures and precipitation in good dispersion. Mid-September rain allows the development of noble rot to spread in the vineyard, turning 2017 into one of the greatest vintages for sweet wine in the last decade. -
