The art of wine-tasting

Wine-tasting is an art which requires practice, concentration and … a great deal of modesty. Anyone can become a good wine-taster! Wine-tasting is the art of appreciating a wine with three of our five senses: sight, smell and taste.

Eyes (Colour):

The different aspects we perceive are:

  • Colour - highlights - brilliance
  • Clarity
  • Arches
  • Effervescence.

The colour gives information on the origin of the wine and its age.

Examples:

  • From a pale-straw or yellow for young white wines to amber-yellow and brown for older vintages.
  • From purple-red for young red wines to brick red for older vintages.

The clarity is indicative of a stable and healthy wine.

Arches: Sometimes when swirling a glass of wine, one can see the wine form into lines that stream down the glass. These are also referred to as “legs” or “tears”. They form when alcohol evaporates from the film of wine, coating the inner surfaces of the glass. Because ethanol volatilizes more rapidly than water, the surface tension of the film increases. This induces water molecules in the film to pull together more tightly, resulting in droplet formation. Finally the drops slide down, forming the tears.

Effervescence (or perlage) is due to the presence of carbon dioxide that, freed when the wine is poured, results in foam and bubbles. It is vital for sparkling wines: bubbles must be numerous, small in diameter and persistent. In wines, however, the effervescence is a failure and is indicative of the phenomena re-fermentation alcoholic or malolactic fermentation occurred in the bottle.

Nose (Aroma or bouquet):

The nose represents 80% of wine tasting.

Primary aromas (varietal aromas)
Each grape variety has specific aromas.
Examples:
  • Merlot: Redcurrant
  • Cabernet Sauvignon: Blackcurrant, black pepper
  • Chardonnay: Golden Delicious apple, acacia flower, rose
  • Sauvignon Blanc: Grapefruit, citrus
  • Syrah: Black cherry, violet, peppery notes
Secondary aromas (fermentation aromas)
These aromas are fleeting and disappear after a few months.
Examples: yeast, ferment, banana...
 
Tertiary aromas
These are aromas released during barrel and bottle ageing.
Examples: coffee, tobacco, toasted bread, vanilla...
 
Vocabulary
Big: Describes a wine with above-average flavour intensity.
Earthy: A flavour or aroma that suggests the soil or fresh earth.
Rich, Complex: Richly aromatic nose that can be fruity, floral, spicy...
Finesse, Elegance: Denotes high quality and a sense of style.

Mouth (Taste):

The 4 basic flavours

The different stages:

  • The attack: The first impression, when we usually feel the sweetness of the wine.
  • The evolution: The way the wine develops on the middle palate so that we can feel the acidity and the astringency.
  • The aftertaste: Last perceived aromas, e.g. we can find that a wine is sweet.
  • The length: Aromatic persistency, e.g. a wine can have a short, medium or long finish.
  • The balance or harmony: A good wine always has a good balance. A red wine needs to have a good balance between sweetness, acidity and tannins. A white wine needs to have a good balance between sweetness and acidity.

Vocabulary:

  • Astringent: Showing a little bitterness, indicating the presence of tannins.
  • Soft: Very round, supple, low in acidity.
  • Fleshy: A round, richly-flavoured taste.
  • Flat: Exhibiting a lack of freshness, character or acidity.
  • Firm: A wine that has a well-defined tannin or acid structure.
  • Light: Lacking in body but not unpleasant.
Shortcomings:
Smells, often due to contamination and rarely pleasant.
Examples: acetic, sour, vinegar, petrol, cabbage...
