What are the key factors that influence the taste of wine?

There are several key factors that influence the taste of wine. Firstly, the grape variety used plays a significant role, determining the basic flavors and characteristics. Secondly, the region or terroir where the grapes are grown affects the taste due to variations in soil composition, climate, and elevation. The winemaking process also influences flavor, including fermentation techniques, the use of oak barrels, and aging methods. The level of sweetness or dryness is determined by residual sugar, while acidity provides freshness and balance. Tannins, found in red wines, contribute to structure and mouthfeel. Lastly, the influence of the winemaker's choices, such as grape harvesting time or blending decisions, can impact the final taste. Overall, the interplay of these factors creates the diverse and unique flavors found within different wines.
