Irish whiskey is a smooth and light spirit made primarily from malted and unmalted barley. It is typically triple-distilled, which contributes to its distinctive smoothness. The aging process occurs in wooden casks for a minimum of three years, allowing the whiskey to develop its unique flavors. There are several types of Irish whiskey, including single malt, single pot still, and blended whiskey. Each type has its own characteristics based on the ingredients and production methods used. Popular brands include Jameson, Bushmills, and Redbreast, each offering a variety of expressions to suit different palates.
