The acıkara grape variety, a nearly forgotten native black variety in Anatolia/Turkey, has recently gained interest in its potential for producing high-quality wine from producers and consumers. The potential of producing high-quality red wine from the Acıkara grape variety (vitis vinifera), which is cultivated on the elmalı/antalya in the highland (1100 m altitude) of western mediterranean region, was investigated, and the suitability of the wine’s characteristics associated with high-quality red wine was determined.

Une approche très simple de la lecture des paysages est proposée sur la base de l’expérience acquise par l’observation de divers terroirs du monde.

Le système des appellations d’origine aux Etats-Unis était adopté en 1978 et est entré en vigueur en 1983. Jusqu’à présent, 146 aires viticoles avaient été établies dans 26 états.

Enzymatic browning (BE) of must is caused by polyphenol oxidases (PPOs), tyrosinase and laccase. Both PPOs can oxidize diphenols such as hydroxycinnamic acids (HA) to quinones, which can later polymerize to form melanins [1], which are responsible of BE in white wines and of oxidasic haze in red wines. SO₂ is the main tool used to protect must from BE thanks to its capacity to inhibit PPOs [2]. However, the current trend in winemaking is to reduce and even eliminate this unfriendly additive. Among the different possible alternatives for protecting must against BE, the inoculation with a selected Metschnikowia pulcherrima MP1 is without any doubt one of the most promising ones.

Aromas are one of the key points in food analysis since they are related to character, quality and consequently consumer acceptance. It is not different in the winery industry, where the aromatic profile is a combination of viticultural and oenological practices. Based on the development of more aromatic clones and on the potential to produce sparkling wines at Caldas, in the southern region of Minas Gerais (Brazil) (21°55´S and 46°23´W, altitude 1,100m), the aim of this work was the determination of volatile compounds in six different clones of Chardonnay grape berries to better understand which compounds add bouquet to the wine, and additionally comprehend the impacts of the edaphoclimatic and annual conditions on the improvement of grape-growing and winemaking practices.
