What should I look for when tasting wine?

Take a mouthful of wine (not too much) and swirl it around your mouth (so every taste bud gets a chance to taste it). Professional tasters draw in air at the same time to increase the contact with air and give the wine a chance to evolve in the mouth.

1. Spit it out (optional, unless you've got 20 wines to taste!).Can you taste the sweetness? Sweetness is tasted at the tip of the tongue. It tastes sugary. It comes from the sugar in ripe grapes that is left after fermentation has finished. Is the wine dry, medium or sweet?
2. Can you taste the acidity? Acidity is tasted on the sides of the tongue and tastes like lemons. It occurs naturally in grapes and is important to balance sweetness. White wines have more acidity than red wines. Does the wine have low, medium or high levels of acidity?
3. Can you taste the tannin? Tannin is tasted at the back of the tongue and tastes bitter like a strong cup of tea that makes your mouth fur up. It also has the sensation of an under ripe or green banana. Tannin comes from the skins of the grapes and from oak ageing. It is mainly found in red wines.
4. What flavours can you taste? Fruity, Savoury, Dairy, Nutty, Spicy, Mineral, Sugary, Woody, Floral, Herbal
5. Are the flavours weak or pronounced?
6. Can you feel the alcohol? Alcohol is sensed at the back of the throat and gives a warming sensation. The higher the level of sugar in the grapes before fermentation, the higher potential alcohol the wine will have, i.e. hotter countries tend to produce wines higher in alcohol.
7. Are there low, medium or high levels of alcohol? You can also see this from the 'legs' left on the sides of the glass. This is also an indication of sweetness.
8. How 'long' is the wine? This is a term that describes the length of time you can taste the wine once you have swallowed (or spat it out!). Is the length, short, medium or long? It gives an indication of quality. The longer the length, the higher the quality.

What can the taste tell you?

Quality: A good sign of quality is balance. A wine is balanced when all of the wine's components (e.g. sweetness, acidity, tannins) blend together. The balance or potential to be balanced after ageing is a sign of quality.

Maturity: Older red wines tend to taste more savoury and spicy. Older white wines tend to taste more honeyed and yeasty. Younger wines tend to taste more of fruit.

Origin: Hotter countries mean riper grapes and more overtly fruity wines (and a higher degree of alcohol).

Grape Variety: Certain grape varieties taste of certain flavours, e.g. Sauvignon Blanc typically tastes and smells of gooseberries, Cabernet Sauvignon of blackcurrants.
