Complexity
A quality characteristic describing a wine with multiple layers of aromas and flavours that evolve and change over time in the glass — rather than showing a single, simple note.
In depth
A complex wine reveals different aromas and flavours as it opens up in the glass. Primary aromas may be initially dominant, then secondary and tertiary notes emerge as the wine warms and oxidises. On the palate, complexity means the flavour profile shifts from front to mid-palate to the finish — different sensations at different stages.
Complexity is often the result of: superior terroir (a vineyard site that imprints distinct mineral character); careful viticulture (low yields, optimal ripeness); sensitive winemaking (respecting the wine's natural qualities); and ageing (bottle age develops tertiary aromas that add layers).
In wine certification exams, complexity is a quality indicator that must be supported with specific examples. Writing "the wine is complex" without naming what makes it complex scores no marks. Instead: "Complex nose showing primary red cherry and raspberry alongside secondary cream notes, developing tertiary leather and forest floor — suggests considerable complexity."

Frequently asked questions
- What makes a wine complex?
- Complexity comes from multiple, distinct layers of aroma and flavour that evolve over time — rather than a single obvious note. It can come from terroir (specific mineral/soil character), grape variety (naturally aromatic varieties like Riesling or Nebbiolo), winemaking (lees ageing, oak, MLF), and bottle ageing (which develops tertiary notes). A complex wine rewards attention — you find something new each time you return to the glass.
