Guide to Tasting Wine

Wine tasting (often, in wine circles, simply tasting) is the sensory examination and evaluation of wine. While the practice of wine tasting is as ancient as its production, a more formalized methodology has slowly become established from the 14th century onwards. Modern, professional wine tasters (such as sommeliers or buyers for retailers) use a constantly-evolving formal terminology which is used to describe the range of perceived flavors, aromas and general characteristics of a wine. More informal, recreational tasting may use similar terminology, usually involving a much less analytical process for a more general, personal appreciation. The results of the four recognized stages to wine tasting.

 

• appearance
• "in glass" fragrance
• "in mouth" sensations
• "finish" (aftertaste)

All of these things are combined in order to establish the following properties of a wine: complexity and character, potential (suitability for aging or drinking) and possible faults A wine's overall quality assessment, based on this examination, follows further careful description and comparison with recognized standards, both with respect to other wines in its price range and according to known factors pertaining to the region or vintage; if it is typical of the region or diverges in style; if it uses certain wine-making techniques, such as barrel fermentation or malolactic fermentation, or any other remarkable or unusual characteristics.

Whereas wines are regularly tasted in isolation, a wine's quality assessment is more objective when performed alongside several other wines, in what are known as tasting flights. Wines may be deliberately selected for their vintage - horizontal tasting or proceed from a single winery - vertical tasting, to better compare vineyard and vintages, respectively. Alternatively, in order to promote an unbiased analysis, bottles and even glasses may be disguised in a blind tasting, to rule out any prejudicial awareness of either vintage or winery.

Blind Tasting

To ensure impartial judgment of a wine, it should be served blind — that is, without the taster(s) having seen the label or bottle shape. Blind tasting may also involve serving the wine from a black wine glass to mask the color of the wine. A taster's judgment can be prejudiced by knowing details of a wine, such as geographic origin, price, reputation, color, or other considerations.

Scientific research has long demonstrated the power of suggestion in perception as well as the strong effects of expectancies. For example, people expect more expensive wine to have more desirable characteristics than less expensive wine. When given wine that they are falsely told is expensive they virtually always report it as tasting better than the very same wine when they are told that it is inexpensive. French researcher Frédéric Brochet "submitted a mid-range Bordeaux in two different bottles, one labeled as a cheap table wine, the other bearing a grand cru etiquette" and obtained predictable results. Tasters described the supposed grand cru as "woody, complex, and round" and the supposed cheap wine as "short, light, and faulty." Blind tastings have repeatedly demonstrated that price is not highly correlated with the evaluations made by most people who taste wine. On the other hand, some extremely expensive wines of great fame, such as Chateau Petrus and Domaine de la Romanée-Conti, consistently receive the highest ratings in blind tastings of professional reviewers such as Robert Parker.

Vertical and horizontal tasting

Vertical and horizontal wine tastings are wine tasting events that are arranged to highlight differences between similar wines.

• In a vertical tasting, different vintages of the same wine type from the same winery are tasted. This emphasizes differences between various vintages.
• In a horizontal tasting, the wines are all from the same vintage but are from different wineries. Keeping wine variety or type and wine region the same helps emphasize differences in winery styles.

Tasting flights

Tasting flight is a term used by wine tasters to describe a selection of wines, usually between three and eight glasses, but sometimes as many as fifty, presented for the purpose of sampling and comparison.

Glasses used in tasting flights are usually smaller than normal wine glasses, and they are often presented on top of a sheet of paper which identifies each wine and gives some information about each grape or vineyard. This format allows tasters to compare and contrast different wines.

An extended tasting will typically consist of several flights, each with a theme. For example, several wines from the same region and vintage would comprise a flight, or several wines from the same variety but different regions. It is typically the responsibility of the tasting organizer to select flights that offer maximum illumination of similarities and differences, while at the same time making sure the progression of flights is appropriate.

Order of tasting

Tasting order is very important, as heavy or sweet wines can dominate lighter wines and skew the taster's assessment of those wines. As such, wines should be tasted in the following order: sparkling wines; light whites, then heavy whites; roses; light reds; heavy reds; sweet wines.

Without having tasted the wines, however, one does not know if, for example, a white is heavy or light. Before tasting, try to determine the order the wines should be assessed in, by appearance and nose alone. Remember that heavy wines will be deeper in color and generally more intense on the nose. Sweeter wines, being denser, will leave thick, viscous streaks (called legs) down the inside of the glass, when swirled.

The wine tasting process

There are five basic steps in tasting wine: color, swirl, smell, taste, and savour. This is also known as the five Ss: See, Swirl, Sniff, Sip, Savor. During this process, a taster must look for clarity, varietal character, integration, expressiveness, complexity, and connectedness. A wine's color is better judged by putting it against a white background. The wine glass is put at an angle in order to see the colors. Colors can give the taster clues to the grape variety, and whether the wine was aged in wood.

Characteristics assessed during tasting

Varietal character describes how much a wine presents its inherent grape aromas. A wine taster also looks for integration, which is a state in which none of the components of the wine (acid, tannin, alcohol, etc) is out of balance with the other components. When a wine is well balanced, the wine is said to have achieved a harmonious fusion.

Another important quality of the wine to look for is its expressiveness. Expressiveness is the quality the "wine possesses when its aromas and flavors are well-defined and clearly projected. The complexity of the wine is affected by many factors, one of which may be the multiplicity of its flavors. The connectedness of the wine, a rather abstract and difficult to ascertain quality, is how connected is the bond between the wine and the land where it comes from.
