What country has the most spiciest chili pepper in world?

There isn't a single country that can claim the title of "most spiciest chili pepper in the world." The spiciest chili pepper varies by year, as new varieties are continually being cultivated and discovered.

However, here are some countries known for producing extremely hot peppers:

* Bolivia: Home to the Carolina Reaper, which held the Guinness World Record for spiciest pepper for a while.

* India: Produces the Bhut Jolokia (also known as Ghost Pepper), which was once the hottest pepper.

* Thailand: Known for the prik kee noo, which holds the title of spiciest pepper in the world for some.

* Mexico: Produces a wide variety of hot peppers, including the habanero and jalapeño.

* China: Produces sichuan peppers known for their unique numbing heat.

Ultimately, it's more about individual pepper varieties than specific countries when it comes to the "spiciest" title.
