How wines are scored and what are the influencing factors

There are many factors that can affect the character and quality of a wine, but the most important are none other than three factors: the grapes, the vineyard and the winemaking technique.

There is no correlation between the vintage of a wine and the quality of the wine, and it cannot be said that the older the vintage, the better the quality of the wine.

Because the quality of wine grapes is an important factor in determining the quality of wine, if the temperature, precipitation and other conditions of a certain year are more suitable for grape growth, the quality of the grapes of this year is good, and the quality of the wine made from the grapes picked in this year will naturally be good.

Only the juice extracted from the grapes of the current year can be used to produce a wine that bears the vintage of the current year. Moreover, the quality of the wines varies greatly from vintage to vintage, as is often the case with the perception that the longer the vintage is marked, the better the quality.

The age of the wine can only indicate the year of the grapes from which they are made, and can neither be used as an absolute criterion for judging the quality of the wine, nor can it be used as a basis for the price of the wine.

Wine is the product of the relationship between man and nature, and is the result of people using corresponding cultivation techniques, planting certain grape varieties, harvesting their fruits, and making wine through corresponding processes under certain climate, soil and other ecological conditions. Therefore, the ecological conditions of the place of origin, the grape varieties and the varieties used to cultivate the grapes, harvesting and winemaking methods determine the quality and style of the wine.

Wine quality is affected by several factors:1Depending on the variety, the quality of the wine will be correspondingly different2

The yield and quality of the grapes are related to the quality of the wine3Natural factors such as the environment of origin and climate determine the quality of grape varieties, and then affect the quality of wine.

There are now grape varieties in the world.

Seven or eight thousand, but there are only more than 30 varieties of wine grapes cultivated over a large area. According to the practical experience of wine making at home and abroad, the varieties suitable for making high-grade red wine are Cabernet Sauvignon, Cabernet Franc, Saphia Sauvignon, Plum Luxu, etc., these varieties have a grassy aroma, and the wine produced has an elegant and rich wild fruit aroma. The varieties suitable for making white wines are Chardonnay, Riesling, Guirenxiang, Semillon, and Chenin Blanc.

The white wines produced by these varieties are fruity and elegant. In addition, good wine grape varieties must be planted in the right soil and climatic conditions in order to show excellent characteristics and make high-end wines. Secondly, climatic conditions.

Including moisture, humidity, wind speed, etc., the climatic conditions vary from year to year, so the quality of the wine produced varies from year to year. Grapes have the highest water requirement at the beginning of growth and decrease during flowering, while the water requirement increases during the growing season and the lowest moisture requirement during the ripening period. The fruit is rainy during the ripening period, resulting in low sugar content, high acid content, and easy to cause diseases.

Drought and flood were not conducive to the growth and development of grapes and the ripening of berries. A light breeze is good for the grapes, and a strong wind is not good for the grapes. Grapes cultivated in dry places are of good quality and have fewer pests and diseases, and grapes produced in famous wines from all over the world are cultivated on hills or slopes, with good ventilation and light transmission on the slopes, good fruit coloring, high sugar content, and strong fragrance.

In the northern foothills of the Tianshan Mountains in Xinjiang, China, the natural ecological environment can grow high-quality Cabernet Sauvignon, Chardonnay and other grape varieties, which effectively guarantees the quality of the grapes for winemaking.
