A whisky cask is a medium-sized barrel containing alcohol.Most Scotch whiskey is aged in bourbon barrels also known as "traditional" whiskey casks. They are ideal for aged Scotch whiskeys due to their ready availability and affordable prices.
Depending on the type of keg, it can hold between 170 and 750 bottles of standard whiskey when first filled.In addition to all the flavors the distillery itself provides, there is one factor that greatly influences the taste of a whiskey and that is the cask in which it is aged.You can find the best Whisky cask via www.vintageacquisitions.com/whisky-cask-investment-guide/.
The production process gives the whiskey about 20-30% of its style and taste with the rest coming from oak. Oak is a very durable wood, but it is also slightly porous, which allows the barrel to breathe. In humid conditions like Scotland, this allows a small amount of alcohol to evaporate into the air each year, but it also draws spirits deep into the trees.
As temperatures fluctuate from month to month and year to year, the tree slowly expands and contracts. Spirits are drawn in and out of the oak, softening it and adding flavor and color.
Barrel is responsible for the assembly and maintenance of the main barrel. It takes years to become a master cooper, as hand tools are still required. Thousands of barrels a year need major repairs, and thousands more need to be re-burned.
