What is whiskey?

Whiskey, which comes from the Scottish Gaelic, uisge-beatha and the Irish uisce beata, fuisce or güisqui, which at the end means "water of life" from the Latin aqua vitae, aquavit. But in Spanish they are only whiskey or whiskey.
It is the result of the distillation of the fermented must of cereals such as corn, milkshake, rye, barley or wheat, and its subsequent aging, in white oak barrels.
The sale is when it has an alcoholic content of 40% or 62% of the volume.
Its origin is uncertain. In Ireland the oldest information is from 1405 and in Scotland there are data on its handling since 1496, but it is believed that it had been invented for a few centuries.
Malt whiskey:
It is made of malted barley and distilled in an alembic created for this type of whiskey called "pot srill" and which is shaped like a beet or onion. It is left to age between 8 and 12 years and then bottled, leaving a strong whiskey with a very strong flavor.
Grain whiskey:
This is made from malted or unmalted barley, corn and other types of cereals. This is distilled in “Coffey stills” a continuous distillation alembic.

There are many ways to combine malt and grain whiskeys:
"Blended Malt". It is the way in which the malt mixtures are currently called, or (Vatted Malt). They are mixtures from different distilleries, and are known as “pure malt”. If a whiskey is called “pure malt”, it is labeled as blended malt whiskey, with those made with grain being out of denomination.
It is common for a whiskey to come from a single distillery and that is why it is marked as (Single malt) even if it has a mixture of several barrels, and if it is from only one it will be marked as “single cask”. The name of the whiskey is usually marked with that of the distillery, and the years of aging. It is also marked if the whiskey was aged in a port sherry or bourbon barrel.
Whiskeys do not mature in the bottle, so age is measured by the time between distillation and the barrel. The oldest whiskeys being more valued.
