How is the old whisky is precious than new?

Answer 1

it's aged longer in wooden kegs . . the longer it's aged the smoother the flavor

Answer 2

When whisky has an age marked on the bottle it means it has been aged in wooden barrels.

Various chemical actions take place over the years. The whisky softens, it gains complex flavors from the barrels, not just wood but - because they are usually secondhand barrels that have been used for wine, sherry, port, bourbon* etc - extra flavors from them. Also some of the whisky evaporates through the pourous wood of the barrel, concentrating what is left.

It costs money to keep whisky maturing 8,10 or more years, plus as some is evaporating all the time, they end up with less than they started (the evaporated spirits are known as 'the angels share')

Once the whisky is bottled, matturation ceases. It doesn't mature in the bottle and is ready to drink.

* some whiskys, such as Glenmorangie, have different bottlings which identify which type of barrel was used. Glenmorangie has Sherry,Port, Madeira, Malaga, Bourbon and Burgundy. Youcan buy a tasting case of small bottles of each to compare the different flavors. see http://www.glenmorangie.com/shop/products.php?cat=1
