Les délimitations AOC dans la partie méridionale de la région des Graves « Graves » désigne une nature de terrain très répandue sur la rive gauche de l’axe Garonne- Gironde. Ce terme est utilisé le plus souvent pour désigner la région comprise entre Langon et Bordeaux. Avec Graves (mais aussi Cernès), une certaine unité de dénomination caractérise l’ensemble pédologique « graves » au 18ième. Aujourd’hui cet espace assez homogène est scindé en plusieurs entités distinctes, dont bien sûr le Sauternais. Notre propos est ici de rechercher pourquoi au cours du 19ième siècle puis dans la première moitié du 20ème siècle une appellation régionale n’a pas pu émerger sur toute la partie méridionale largement consacrée aux « grands vins blancs » ? Pourquoi l’ancienne Prévoté royale de Barsac n’a pas été convoquée comme territoire viticole, comme ce fut le cas pour la Juridiction de Saint-Emilion ? Il ne s’agit pas de refaire par le menu l’itinéraire de l’appellation Sauternes mais de comprendre comment au sein de ce vaste ensemble régional, cinq communes ont pu ainsi s’isoler des autres. -

Two territories of similar extension and with historical coincidences in their development have been selected: the Okanagan Valley, Canada, and the region of Somontano, Spain. Methodologically, an analysis of the content on Twitter has been performed, collecting 1377 tweets. The conclusion is that wineries create sentimental and experiential links with the users, avoiding commercial communications. Specifically, Okanagan wineries establish a relevant conversation network on Twitter based on the high percentage of responses, which is 31.3%, but this is not so in the case of Somontano, which is 12.8%. The tourist attractions most used to create a bond are the wine landscape and the gastronomy in the case of both territories. The tourism sustainability variable remains a minor matter in the emission of messages on Twitter.

Estevinho Mountain Research Centre (CIMO), ESA - Polytechnic Institute of Bragança, Campus de Stª Apolónia, Apartado 1172, 5301–855 Bragança, Bragança, Portugal Key words: mead, sweetness, ethanol content, fermentations, sensory analysis Mead is a traditional alcoholic beverage obtained by fermenting mead wort; however, its production still remains frequently an empirical exercise. Different meads can be produced, depending on fermentation conditions. Nevertheless, to date few studies have been developed on factors that may infl uence mead quality. The main objective of this work was to study the infl uence of sweetness and ethanol content on mead acceptability. Different meads were produced with two sweetness levels (sweet and dry meads) and three ethanol contents (18, 20, 22% (v/v)), adjusted by brandy addition. Afterwards, meads acceptability was evaluated by sensory analysis through a consumers’ panel (n=108) along with chemical analysis by HPLC-RID of glucose, fructose, ethanol, glycerol and acetic acid. The sweet (75 gglucose+fructose/L) and dry (23 gglucose+fructose/L) meads presented glycerol contents equal to 5.10±0.54 and 5.96±0.95 g/L, respectively, that were desirable since glycerol improves mead quality. Low concentrations of acetic acid were determined (0.46±0.08 and 0.57±0.09 g/L), avoiding the vinegar off-character. -

Tutored Wine Tasting
Tutored Wine Tasting PORT Speaker: Eric LAGRE Sommelier Port is the classic fortified wine from the Douro, the name of which derives from Oporto (Porto), the second largest city in Portugal, whence the wine has been shipped for over 300 years. Remains of stone troughs for the fermentation of foot-trodden grapes dating back to at least the 3 rd and 4 th centuries can be found throughout the Douro Valley, upstream from Oporto. But the denomination “Porto/Port”, however, only appeared during the second half of the 17 th century, coinciding with a boom in viticulture and wine export initiated by English merchants. Port has actually often been described as the archetypal wine of the British, and the reason for that is not difficult to discover: Port was created by the British for the British market. HISTORY The 1386 Treaty of Windsor was the first of a series of treaties to build strong and active links between Portuguese coastal cities and London. By the time of the reign of Henry VII, the English had established businesses and trade associations benefiting from certain diplomatic privileges in the ports of Lisbon, Oporto, and most importantly, as far as the wine trade was concerned, Viana do Castelo, in the Minho, right to the north of the county. Portuguese wines were often traded for woollen goods from England or dried, salted cod from Newfoundland, bacalhau thus becoming a staple of Portuguese cuisine. Since the thin and astringent Vinho Verde of the Minho was not a wine to the liking of the English consumer, English merchants would rely on Portugal only when needed, mostly because it was the easiest option in terms of shipment. -
Port Wine: Production and Ageing Juliana Milheiro, Fernanda Cosme, Luís Filipe-Ribeiro and Fernando M
Chapter Port Wine: Production and Ageing Juliana Milheiro, Fernanda Cosme, Luís Filipe-Ribeiro and Fernando M. Nunes Abstract Port wine is a traditional and worldwide renowned fortified wine produced in the Douro Demarcated Region (DDR) Northeast of Portugal by specific and tradi- tional winemaking practices. The final quality and uniqueness of the different Port wine styles are highly dependent on the ageing process, namely time, temperature and oxygen levels that will ultimately dictate the type and extension of the chemical changes that occur during this process. These chemical changes occurring during the Port wine ageing process results in significant changes in colour and aroma according to the different ageing conditions employed for the different Port wine styles. This chapter intends to give a broad and generic overview of the known and potential chemical changes occurring during ageing of Port wine that are respon- sible for the changes in the sensory profile observed during the ageing process. Also, the known chromatic and aromatic characteristics of the different Port wine styles and the specific ageing processes, reductive or oxidative, are reviewed. Keywords: Port wine, Douro Demarcated Region, ageing process, colour, aroma 1. Introduction Port wine is a traditional fortified wine produced in the Douro Demarcated Region (Northeast of Portugal in the Douro Valley, Figure 1) under very specific conditions. There are several Port wine styles being related to the winemaking and ageing process and also to the ageing time, which enhances uniqueness to the wines and recognition throughout the world. The Douro Demarcated Region is located within the Douro River basin, surrounded by mountains, having a total area of approximately 250,000 hectares. -

Making Port Wine
Making Port Wine Authentic red port may be made from many grapes, mainly Tinta Barroca, Tina Cao, Bastardo, Tempranillo and others. In California Zinfandel or even Syrah make fine ports. The technique below is universal, and may produce a Ruby port (aged in steel, glass or oak for two to 4 years), or a Tawny port (aged in oak, without topping for several years). Tawny port will lose color and may be blended with other ports to suit the winemaker. Technique: 1. Harvest late at an elevated brix (26 to 30 will do). This is to augment the short primary fermentation time and to maximize the fruit’s natural alcohol production. Fruit should be overripe, but no raisins. 2. Aerate the must well prior to and during inoculation. Choose the yeast carefully; select a yeast that is easy to kill with alcohol. Consider reducing yeast nutrients. Sulfite as normal. But bear in mind that the late harvest fruit is probably at a high pH which can will greatly reduce the effectiveness of sulfites. Color extraction can be a problem, so consider cold soaking (after sulfiting) and/or supplementing the must with OptiRED or pectic enzyme. 3. At 10 to 12 brix, juice should be at 9.5 to 10.5% abv (Alcohol by Volume). Once the juice reaches the target brix; say 11°, fortify the must or juice per formula below. Final alcohol content fo the finished port should be 18.5 to 20% abv. 4. Fortify with grape neutral spirits (GNS) at 190-proof (95% abv), or use aged or unaged brandy at 140-proof (70% abv) or above. -
