Many reasons
- Availability
- Relatively easy to bend and shape
- Provides the best balance of being tight yet porous (good for aging)
- The flavors added to wine from oak complement its flavor
Approximately 2 quarts of wine evaporates from an oak wine barrel in a month. This allows the wine to become more concentrated in flavor and aroma.
Oak wood is used to build wine barrels. The type of oak affects the wine's colour, flavour, texture and tannin profile. In America, white oak is generally used for wine barrels.
Barrel fermentation in wine adds unique characteristics and flavors such as oak, vanilla, spice, and creaminess. The process can also enhance the wine's complexity and texture, creating a richer and more rounded taste profile.
Generally, white oak is used.
There is no oak in wine. Wine is aged in oak barrels to give it a certain flavor.
Quite simply, unwooded Chard or "unoaked" is wine that has never seen the inside of an oak barrel. Typically it will be wine that is fermented in a stainless tank, as opposed to a wooden (oak) cask/barrel. The oak typically helps to balance the tannins, among other things, and gives wine that "full mouth" feel with lots of mid-palate tastes. Unoaked wines are great for people who claim to have an "allergy" to wine. It is the tannins that people typically react to, and those come from both the skins and stems of the grapes, but also from the oak barrels. If you don't "oak" a wine, the you have a lower tannin level which should make the wine bearable to drink for the aforementioned crowd.
The curved wood on a barrel is called staves. Staves are the individual wooden pieces that are joined together to form the barrel's cylindrical shape. They are typically made from oak and are held together by metal hoops. The design allows for the storage and aging of liquids, such as wine or whiskey.
Aging wine in oak tends to improve the flavor.
A new 59 gallon oak barrel weighs about 120 lbs when empty. 600 lbs when full of wine. Used barrels weigh more due to the wine/spirit that has soaked into the grain. The weight can vary due to shape, construction and forest source. Barrels should always be filled on specially made racks. Don't attempt to lift a full barrel(s) without a forklift, a loaded 2-barrel rack can weigh 1250 lbs.
Wine corks are typically made from the bark of cork oak trees. They contribute to the preservation of wine by creating a tight seal in the bottle, preventing oxygen from entering and spoiling the wine. This helps maintain the wine's flavor and quality over time.
When whiskey is bottled a number of oak barrels are dumped and blended together and bottled. Single Barrel Whiskey is bottled from one single oak barrel. Double barrel whiskey is aged in oak barrels then they are dumped and sometimes the proof is lowered and then put into a second new oak barrel to be aged again.
