It is known that in temperate climates cluster thinning improves the quality of the wine. However, there are few studies available about this subject for the tropical vineyards in high altitude with double pruning technique.

Leaf and grape removal are antiques cultural practices used in Montsant region to improve wine color and structure of Grenache (Vitis vinifera L.).

Sparkling wine production in cool climates has particular focus on the composition of the phenolics present in the finished wine, however little is to be found in the literature as to how fruit can be manipulated to produce the desired result.

The main objective of our study was to improve Tannat grapes and wine composition, by achieving appropriate vine balance. Three factors were evaluated in a split-split-split plot design with four replicates.

The effects that irrigation may have on the enological response of Galician traditional red grapevine cultivars are not well known.

In Douro Region (Northeast Portugal) grapevines are often exposed to severe water stress in the summer. During 11 years (2002 – 2012) a study was conducted in a commercial vineyard with cv. Touriga Nacional x 196-17 growing under three water regimes, non-irrigated (NI) and two irrigation strategies (WR1-30% ETc and WR2-60% ETc).

An experiment was conducted in the Barossa Valley, South Australia to examine the effects of rootstock on reproductive performance of Shiraz (Vitis vinifera L.) in the absence of irrigation.

Vitis vinifera L. cv. Garnacha Blanca (White Grenache) is the prior grape variety in the D.O. Terra Alta (Tarragona, Spain), where it has been recently irrigated; however, there are no studies about the most suitable irrigation scheduling and the consequences of irrigation on plant physiology and grape and wine aromatic profile.

Vineyards are usually managed using tillage to eliminate competition from other plants. However, this practice presents several drawbacks including degradation of soil structure, loss of organic matter and it may lead to considerable soil loss if the vineyard is on a slope.

The ancient practices for cultivating vines often associated vines with trees. Traditionally, the trees provided a physical support for the vines to climb on.

Excerpt

Rotundone is a very potent aromatic compound, identified for the first time in 2008, in Shiraz wines by an Australian research team. There are still few very studies on this impact molecule, responsible for heavy peppery notes in wines.

The research studies offer a great contribution to the reduction of production costs in the following ways: 1- total reduction in vineyard operations, even down to a tenth,

This study will present results of research conducted on new production models that allow the elimination of all vineyard practices and therefore all production costs apart from planting and harvesting.

The vineyards in the D.O.C. area Friuli Colli Orientali are planted mainly in hills with different expositions and high soil composition and texture variability.

The principle terroir of studies consists of mapping environmental factors and characterizing the viticultural potential.

Nitrogen management and water status of grapevines are determining factors in wine quality.

Carignan occupies over than 30 % of the total surface planted in Montsant region. Absorption capability of macro and microelements by the grapevine is in a part responsible of the total concentration and variability of compounds participant on grain quality.
