Single Vineyard refers to a specific category in wine terminology where the grapes used to produce the wine are sourced exclusively from one particular vineyard. This is significant because it suggests that the wine expresses the unique characteristics or "terroir" of that specific location. Terroir is a French term that encompasses the various environmental factors such as soil type, climate, and topography, which can impart distinct qualities to the grapes and therefore influence the flavor and character of the wine.

Wines made from single vineyards are often labeled as such and can be sought after for their specificity and representation of a particular place. They are distinct from blends, where grapes from different vineyards are combined, which can also create excellent wines but do not offer the same level of traceability or specific regional character.
