Single vineyard
Single vineyard, in Danish often called enkeltmarksvin, refers to a wine made exclusively from grapes from one particular, named vineyard. Instead of blending fruit from several plots or a whole village, the producer here wants to capture the expression of just this single piece of land: its altitude, slope, soil and microclimate. The idea is that a small, defined parcel has its own voice, and that a wine from that vineyard alone shows the terroir more clearly than a blend does.
This matters for what you taste and smell. A single vineyard wine is often more focused and shaped by the site's characteristics, for example the mineral freshness from chalky or sandy soil, or the slow ripening you find in high-lying vineyards. The vineyards are typically small and yield few bottles, so the wines are usually made with great care and longer ageing. You recognise them because the label names the vineyard, often in addition to the grape and the region.
A widespread misunderstanding is that single vineyard automatically means higher quality. It is not a guarantee, but an expression of a particular approach in which the site is placed at the centre rather than the average of a larger area. In some regions there are formal designations for the category (in Rioja, for example, Viñedo Singular), while elsewhere it simply appears as the vineyard's name on the bottle.
