Okay, so Irish whiskey is a kind of drink that people can drink. It's made in Ireland, which is a country across the big ocean from America. Irish whiskey is made from things called barley, water, and yeast. These things are mixed together and left to sit for a while. Then they're heated up until they turn into a kind of liquid called "wash."
The wash is then put into big pots called stills. These stills make the liquid get really hot, and this causes the alcohol to separate from the water. The alcohol is then captured and put into barrels. These barrels are made of wood and they help to give the whiskey a really good taste.
The whiskey is left in the barrels for a while, sometimes for many years! The longer it stays, the better it tastes. After it's been in the barrels long enough, the whiskey is bottled up and sent to stores where people can buy it and drink it.
Irish whiskey is a very special drink because it's been around for a long time (over 1,000 years!) and it has a lot of history and tradition behind it. Some people really like the taste of Irish whiskey, and some people even use it in cooking! But no matter how you drink it, Irish whiskey is always something to be enjoyed and appreciated.
