Amphora Wines: To Pitch Or Not To Pitch

Abstract

Amphora wines are known in Portugal as Vinhos de Talha. In this technology, alcoholic fermentation takes place in clay vessels that traditionally were pitched inside using pine pitch. Vinhos de Talha has a distinctive sensorial profile, due to the ancestral technique of vinification. However nowadays, some clay vessels are impermeabilized with other materials than pitch, such as bee wax and mainly epoxy resins.

The present research is a first study to evaluate if different clay vessels impermeabilization materials impact the volatile profile of wines. Fot that objective, white wines were produced in clay vessels with different coatings: new pitch, old picth, epoxy resin, bee wax and no coating. The volatile composition was analyzed by headspace solid phase microextraction hyphenated with gas chromatography / mass spectrometry (HS-SPME-GC/MS).

A linear discriminant analysis shows that wines can be discriminated according to different clay vessels impermeabilization materials, being the most similar the ones from clay vessels with no coating and the ones from clay vessels with old pitch.

Optimizing the use of bentonite for better control of haze formation In white and rosé wines

In winemaking, the appearance of turbidity in white and wine is a serious visual defect, which lowers significantly its commercial value. A major cause of the formation of turbidity in wine is attributed to the presence of temperature-sensitive proteins.

Phenology, thermal requirements and maturation of the SR 0.501-17 wine grape hybrid cultivated in contrasting climate

The use of hybrids in viticulture is one of the alternatives for sustainable production in hot and rainy regions during grapevine maturation. This sustainable production concerns the reduction of pesticide use, adaptation to climate and control of vine decline. The SR 0.501-17 wine grape hybrid, developed in the grapevine program of the Agronomic Institute of Campinas (IAC), is characterized by producing white grapes with small spherical berries with seeds. The agronomic characterization of this hybrid, especially in different climatic conditions, as well as the evaluation of its performance in winemaking are necessary. The objective of this work was to characterize the duration and thermal requirements of the different phenological stages and the influence of rainfall on the physicochemical characteristics of the must in two contrasting climate regions of the State of São Paulo.

Improvement of sparkling wines production by a zoning approach in Franciacorta (Lombardy, Italy)

Franciacorta is a viticultural area which extends in the hills to the South of Iseo lake in Lombardy. It is particularly famous for the production of sparkling wines obtained mostly from Chardonnay and Pinot blanc and noir grapes. The name of this territory is of medieval origin and appeared for the first time in 1277 as “Franzacurta”, from the Latin “franchae curtes”, i.e. “tax-free” monasteries. It was geographically delimited in 1429, when it was a territory of the Republic of Venezia.
