The main difference between whiskey and bourbon is in the taste. Bourbon has a smoother and thicker taste while whiskey has a slightly stronger taste. Indeed, whiskey and bourbon are two liquors that are quite difficult to distinguish for the novice. They are both the result of distilling a mixture of grains, but it is the composition of this "mash bill" that determines whether it is whiskey or bourbon.
What is Whiskey?

Whisky or whiskey is a spirit obtained by distilling a fermented mixture of cereals generally composed of corn, barley (malted or not), rye and wheat. To this is added yeast and water (lots of water).
The exact origin of whiskey is still subject to a controversy between the Scots and the Irish. Later, the latter brought their know-how to the United States, mainly in the state of Kentucky, which has become the leading producer of whiskey and bourbon in the world.
A bottle of whiskey can be blended or single malt. Blended whiskey is a mixture of liquors from several distilleries. Single malt whiskey is the product of a single distillery and is the most sought-after type of whiskey appreciated by connoisseurs.
The Scotch Whiskey Single Malt remains the most famous of all whiskies, it is obtained with malted barley and contains 40 ° of alcohol by volume. It is a whiskey exclusively made in Scotland and must age for at least 3 years in an oak barrel.
What is Bourbon?

Bourbon is a variety of whiskey made exclusively in the United States. It is a softer, thicker whiskey made from a grain blend of at least 51% added corn with wheat, malted barley or rye added. Barley is rarely used to make bourbon. Bourbon must be aged in white oak barrels. It is mostly produced in the state of Kentucky.
There are two versions as to the origin of its name. The first one says that the name bourbon came from Pastor Elijah Craig who named his productions like this. The second one says that it received this name from the county of Bourbon (Kentucky) which is the first world producer of this liquor.
Differences between Whiskey and Bourbon
1. Origin
Whiskey is a European beverage produced all over the world, but mainly in Scotland and Ireland.
Bourbon is a variation of whiskey that is made only in the United States. That's why it is also called "American whiskey".
2. Basic ingredients (mash bill)
The composition of the mash bill and the percentage ratio of ingredients are the main elements that differentiate a whiskey from a bourbon.
Whiskey is made with a mash bill containing corn, rye, wheat, and malted or unmalted barley.
Bourbon is made primarily of corn, with a ratio of at least 51% of the blend. The rest can be wheat, rye, or malted barley. It is important to note that the corn composition for bourbon making can go beyond 51%, this figure is the minimum percentage that must be respected.
3. Distillation
The difference in taste between bourbon and whiskey is also due to the way in which they were each distilled. A whiskey can undergo a change in taste and addition of coloring at the end of its distillation process. Bourbon, on the other hand, should not undergo any additions or changes after distillation.
4. Aging
The aging processes of bourbon and whiskey are also different. Bourbon must age for at least 2 years in an oak barrel, for a better result some distilleries can let it age for about 6 years.
Whiskey needs to be aged at least 3 years. Single malt can even be aged for about 12 years.

Conclusion
Whiskey and bourbon are two liquors resulting from the distillation of a mixture of cereals. The main difference between these two types of alcohol lies in their taste. Bourbon is sweeter and milder than whiskey. Apart from that, there are also differences in the origin, the ingredients used, the production process, and the aging process.
