Which is the First whiskey of world?

It's impossible to say definitively which whiskey was the "first" in the world. Here's why:

* Distillation's Ancient Origins: Distillation itself has roots dating back thousands of years, likely originating in Mesopotamia and the ancient Egyptians. Early forms of distillation likely resulted in low-quality spirits, not necessarily what we'd recognize as whiskey today.

* Whiskey's Evolving Definition: Whiskey's definition and production methods have changed over time. What was considered "whiskey" centuries ago might not be the same as what we drink today.

* Lack of Definitive Records: Early whiskey production was likely done on a small, local scale, with little documentation.

What We Do Know:

* Ireland & Scotland as Early Centers: Both Ireland and Scotland have strong claims to early whiskey production, likely starting around the 15th century.

* "Aqua Vitae" & "Uisge Beatha": Early references to distilled beverages in these regions used terms like "aqua vitae" (water of life) and "uisge beatha" (water of life) in Gaelic.

* Grains & Mashing: The key ingredient for whiskey was, and still is, grain. Early forms likely used barley, rye, or wheat.

So, while we can't pinpoint the absolute first whiskey, we can say that it likely originated in Ireland or Scotland, and that its history dates back centuries.
