What makes one wine more expensive than another?
How the wine is produced (hand-picking, use of oak etc. adds to the cost)
The origin of the wine(some vineyards are very small and unique - this can push up the price because of supply and demand)
Demand for specific grape varieties (Syrah is twice the cost of Chardonnay as less of it is available but demand is high)
The most crucial factor in a wine's pricing is the level of demand - if a producer can sell his wine 10 times over (like many top Burgundy and California producers) then he is in a position to command a premium price for his product.

What is the proper order for serving wines?

Why are many wines aged in oak barrels?
Firstly, wood, unlike concrete or stainless steel, is porous and consequently allows the wine to be subjected to controlled oxidation. This leads to the tannins softening over time and the wine becoming more fully integrated. Secondly, it is used to impart a flavour and taste to a wine when used judiciously.

How should I order wine in a restaurant?
Make use of the advice of the wine waiter, if there is one.
First choose your food and then decide on your wines.

1. When the bottle arrives, check the following; vintage (often changed without warning), name of the wine, producer.
2. Check that the temperature is satisfactory. It is better for both reds and whites to be too cold than too warm. Don't be embarrassed to ask for an ice bucket to chill both whites and reds.
3. Make sure that each bottle is opened in front of you and that red wines are decanted at the table.
4. When invited to taste the wine, do so. Don't be rushed, do the following: look at it (it should be clear and bright), smell it (it should smell clean and fresh), taste it (it should have no off-flavours).
5. If there is anything wrong, don't hesitate in saying so immediately.

How should I cellar my wine?
The best conditions for wine storage are a stable temperature with a stable level of humidity and no direct light.

Does the food I serve with a specific wine influence the wine?
Yes it does. For example if the food is very spicy, the wine will not taste as strong as it would with no food.
If the food is sweet, the acidity of the wine will show more, if the food is acidic the sweetness of the wine will show more.

What is the Bordeaux classification?
It is an official ranking of some Châteaux from Bordeaux established in 1855 by the local wine trade.
