How to Taste Wine Like a Sommelier: Master Professional Evaluation Techniques
CrushBrew Editorial · Wine Knowledge · 7 min read
Professional sommeliers evaluate wine using a systematic five-step approach called the 5 S’s — See, Swirl, Smell, Sip, Savor — combined with specific structural criteria to identify grape variety, region, and vintage with remarkable precision. The Court of Master Sommeliers certification requires blind identification using exactly these techniques. Learning this method transforms casual wine drinking into sophisticated evaluation and helps you develop your palate like the professionals.

What Are the 5 S’s of Wine Tasting?
The 5 S’s — See, Swirl, Smell, Sip, and Savor — are a systematic framework used by professional sommeliers worldwide to evaluate wine. Each step reveals specific information about the wine’s quality, origin, and characteristics that casual drinkers routinely miss. This method is standardized across major certification programs including the Court of Master Sommeliers and the Wine & Spirit Education Trust (WSET).
The 5 S’s: What Each Step Reveals
| Step | What It Does | Key Information Revealed |
|---|---|---|
| See | Visual inspection | Grape variety, age, alcohol, quality issues |
| Swirl | Release aromatics | Viscosity, alcohol level, aromatic intensity |
| Smell | Aromatic analysis | Origin, winemaking technique, aging |
| Sip | Structural evaluation | Acidity, tannin, alcohol, body |
| Savor | Finish assessment | Balance, complexity, length of finish |
This systematic progression ensures no critical evaluation element is overlooked — exactly as professional sommeliers are trained to approach every wine, from a house pour to a blind tasting flight.
The 5 S’s Framework
A standardized five-step wine evaluation method — See, Swirl, Smell, Sip, Savor — adopted by the Court of Master Sommeliers and the Wine & Spirit Education Trust. The framework ensures systematic analysis of every dimension of a wine before forming a quality or identification conclusion, and is used in both professional service and competitive blind tasting.
How Do Sommeliers Examine Wine Visually?
Sommeliers examine wine visually by assessing color intensity, clarity, rim variation, and viscosity — holding the glass at a 45-degree angle against a white background to evaluate specific markers that indicate grape variety, age, and potential quality issues before a single sniff or sip.
Color intensity indicates grape variety concentration: deep, opaque reds suggest powerful varieties like Cabernet Sauvignon, while lighter, translucent reds point to Pinot Noir. Rim variation tells the aging story — brick red edges indicate a mature wine, while purple-black rims signal youth. Clarity indicates wine health: any haziness may point to filtration issues or potential faults.
Rim Variation
The color gradient between the center of a wine and its outer edge when viewed at a 45-degree angle. In red wines, a purple-black rim indicates youth while a brick or tawny rim signals age and oxidative development. Rim variation is one of the most reliable visual indicators a sommelier uses to estimate a wine’s approximate age before tasting.
What Do Professional Wine Tasters Smell for in Wine?
Sommeliers identify three distinct layers of aromas — primary, secondary, and tertiary — to determine wine origin and quality through systematic olfactory analysis. Professional tasters spend 30–45 seconds on aromatic evaluation alone, identifying 8–12 distinct descriptors that guide their identification process.
Primary aromas come directly from the grape: blackcurrant in Cabernet Sauvignon, peach in Viognier, cherry in Sangiovese. Secondary aromas develop during fermentation — bread, yeast, butter, or cream notes that indicate specific winemaking choices like malolactic fermentation or lees stirring. Tertiary aromas emerge from aging: oak contributes vanilla, spice, and toast; bottle aging develops leather, tobacco, earth, and dried fruit.
Primary, Secondary, and Tertiary Aromas
The three aroma layers in wine. Primary aromas derive from the grape variety itself and reflect terroir and fruit character. Secondary aromas develop during fermentation through yeast activity and winemaking decisions. Tertiary aromas — also called the bouquet — develop during aging in barrel or bottle and add complexity, earthiness, and oxidative notes. Identifying all three layers is central to professional wine evaluation and blind tasting.
How Do Sommeliers Actually Taste and Evaluate Wine?
Professional tasters assess structure — acidity, tannin, alcohol, body — along with balance, flavor evolution, and finish length using the Court of Master Sommeliers deductive tasting grid. Each structural component is evaluated individually on a basic-medium-pronounced scale before an overall quality conclusion is formed.
Sommeliers take a medium-sized sip and allow the wine to coat the entire palate before assessing components in sequence. Acidity creates a mouth-watering, salivating sensation. Tannins provide grip and astringency in reds. Alcohol contributes warmth and body weight. Balance evaluates how all elements work together harmoniously — no single component dominating.
Finish length is the most reliable single indicator of quality. Exceptional wines hold their flavor intensity for 45 or more seconds after swallowing. Top-quality wines also reveal flavor evolution — initial flavors shift and develop as the wine sits in the mouth, with multiple layers emerging over time. Simple wines show little of either.
Deductive Tasting Grid
The structured evaluation template used by the Court of Master Sommeliers for blind tasting assessment. It requires systematic scoring of appearance, nose, and palate components — including sweetness, acidity, tannin, alcohol, body, and finish — using standardized descriptors. The grid leads the taster from observation to a reasoned conclusion about the wine’s grape variety, country of origin, region, and vintage, all without seeing the label.
What Mistakes Should Beginners Avoid When Tasting Wine?
The most common beginner errors are rushing the process, tasting at the wrong temperature, using inadequate glassware, and attempting complex descriptor identification before mastering basic structural evaluation. Professional sommeliers consistently recommend building the foundation first.

Every evaluation component, what it reveals, and the professional scale used to score it
| Component | What It Reveals | Professional Scale | Notes |
|---|---|---|---|
| Color intensity | Grape variety, concentration | Pale / medium / deep | Assess at 45° against white background |
| Rim variation | Age, oxidative development | Purple / ruby / garnet / tawny / brick | Brick edges = maturity in reds |
| Aromatic intensity | Wine expressiveness | Closed / moderate / pronounced | Spend 30–45 seconds minimum |
| Acidity | Freshness, structure, aging potential | Low / medium / high | Salivation rate is the best indicator |
| Tannin | Grip, aging potential (reds) | Low / medium / high; soft / grippy / harsh | Assess texture on gums, not just tongue |
