The process typically includes mashing, fermentation, distillation, and aging in wooden barrels, which contributes to the flavor and character of the final product. Major whiskey-producing countries include Scotland, Ireland, the United States, and Japan. Whiskey is categorized into various types, such as bourbon, scotch, and rye, each with distinct regulations and flavor profiles. The industry has seen significant growth in recent years, driven by increased consumer interest and the rise of craft distilleries. This has led to a diverse range of products and innovations within the market.
