Overall conceptual characterization of aged dry white wines using a mental descriptive questionnaire

Abstract

The purpose of the present study was to understand the overall concept of an aged dry white wine using a descriptive mental questionnaire. A total of 680 worldwide participants, grouped according to their involvement in the wine business, replied to an online questionnaire to characterize the sensory analytical and synthetic descriptors of an aged dry white wine. The descriptors were selected using a Check-All-That-Apply (CATA) approach concerning wine colour, aroma, taste, mouthfeel, and global appreciation.

 

The responses checked by at least 20% of the participants included the following number of descriptors: (a) 5, for the colour; (b) 7, for the aromas; (c) 6, for the taste and the mouthfeel; and (d) 10, for the global appreciation. The involvement level did not influence the diversity of the sensory descriptors. However, highly involved subjects used more frequently terms such as beeswax, kerosene, length and saltiness. Overall, the conceptual space of aged white wines may be characterized by deep yellow to deep gold colour and aromas of dried fruit, honey, caramel, oak and beeswax. The taste and mouthfeel were dominated by acidity, body, length, viscosity, smoothness and dryness. The global appreciation included terms such as complex, persistent, rich, concentrated and developed. A consensual tasting script could have the following text: “Deep gold to amber colour, mature and developed aroma, with notes of dried fruit, honey and caramel. Taste dominated by acidity, encompassing a mouthfeel sensation marked by body, dryness, smoothness and after-mouth persistence.” This overall sensory space is consistent with the metaphorical concept of “mellowed by age” wines, thus avoiding the conceivable negative connotation of “old wine”.

Response of red grape varieties irrigated during the summer to water availability at the end of winter in four Spanish wine-growing regions: berry phenolic composition

Water availability is the most limiting factor for vineyard productivity under Mediterranean conditions. Due to the effects caused by the current climate change, wine-growing regions may face serious soil moisture conservation problems, due to the lower water retention capacity of the soil and higher soil irradiation. The aim of this work was to evaluate the effects of soil recharge irrigation in pre-sprouting and summer irrigation every week (30 % ETo) from the pea size state until the end of ripening (RP) compared to exclusively summer irrigation every week (R) in the same way that RP, on berry phenolic composition at harvest.

Toasting and grain effect on Tempranillo red wine aged in Quercus petraea barrels

The barrel-making process is widely recognized as a crucial practice that affects the composition of barrel-aged wine. After the drying process, the staves are considered ready for barrel assembly, which includes the processes of bending and toasting the barrel structure. Toasting is considered one of the most critical stages in determining the physical and chemical composition of the staves, which can influence the chemical and sensory composition of the wine aged in barrels made from them [1].

The weak role of organic mulches in shaping bacterial communities in grapevine

The interest in sustainable and ecologic agricultural practices in grapevine has grown significantly in recent years in the context of ecological transition. Organic mulches are treatments that support the circular economy and positively affect the soil and the plant. They are an alternative to herbicides and other conventional practices since they may influence soil moisture, erosion, structure and weed control. However, their effects on the soil and must microbiota remain unknown.

Green pruning of shoots to force new sprouting of buds, in fruit set and in pea size: vegetative, productive and maturation effects, in cv. Verdejo

The context of climate crisis leads to the acceleration of technological ripening of grapes, with unsuitable loss of acidity, so various vineyard management alternatives are being considered to delay the grape ripening. The delay of the vegetative cycle towards a period of milder temperatures affects ripening, but vine behavior can vary according to the area, conduction, watering, variety, etc. A work is proposed to know the response to the green pruning of shoots, executed in fruit set and in pea size, in cv. Verdejo.

A phylogenomic study reveals the major dissemination routes of ‘Tempranillo Tinto’ in the Iberian Peninsula

‘Tempranillo Tinto’ is a black-berried Iberian cultivar that originated from a hybridization between cvs. ‘Benedicto’ and ‘Albillo Mayor’ [1]. Today, it is the third most widely grown wine grape cultivar worldwide with more than 200,000 hectares of vineyards mostly distributed along the Iberian Peninsula, where it is also known as ‘Cencibel’, ‘Tinta de Toro’, ‘Tinta Roriz’, and ‘Aragonez’, among other synonyms. Here, we quantified the intra-varietal genomic diversity in this cultivar through the study of 35 clones or ancient vines from seven different Iberian wine-making regions. A comparative analysis after Illumina whole-genome sequencing revealed the presence of 1,120 clonal single nucleotide variants (SNVs).
