There are many different geographical influences affecting the wines’ outcome. This article will discuss the most important five aspects here.
Seasonal Growing Temperature
After the fruit blossoms appear, up to when the harvest occurs, the grapes are in a process of ripening. Average temperatures that the grapes experience will play a big role in the course of their ripening, and will even play on a role on whether they will ripen or not.
Because grapes ripen at different speeds, depending on what the average temperatures are, their speed of ripening determines where the varietals should be planted.
As a general rule, warmer climates allow grapes to ripen to their full potential.
Climate is about weather patterns and atmospheric conditions. These are also a powerful influence on grapes. The climate can either help or destroy them. Wind, rainfall, humidity, hail, frost, quality of sunlight all have an impact on the vines. These elements can effect the thickness of the grapes’ skin which in turn has an influence on the tannins – and the final taste.
High altitude is beneficial to certain grape varietals, as they have cooler temperatures at night and longer growing seasons. This combination means that the wine has more ageing potential.
Soil plays a big role in the growth of the grape. Soil includes sand as well as other elements such as rocks, pebbles, and clay. Soil type also determines how much nutrients the grape receives and how much water it keeps. Grapes actually thrive when nutrients are scarce, and in slightly drier conditions.
The laws and conventions of a region where the wine is being grown and produced determine the different techniques that can be used to make it. Geopolitics determine what is grown, what names can be given to wines, and how they can be labelled.
