What percentage of malted barley must be present in Irish Pot Still Whiskey?

Irish Pot Still Whiskey is defined by its unique production process, which involves using a specific combination of grains. To qualify as Irish Pot Still Whiskey, it must contain a minimum of 30% malted barley, mixed with other grains, typically unmalted barley. This distinctive blend contributes to the characteristic flavor profile of this type of whiskey, differentiating it from other styles produced in different regions, such as Scotland where different regulations apply.

The requirement for at least 30% malted barley is crucial as it represents the foundation of the whiskey's base, influencing both its flavor and mouthfeel. It is this balance between malted and unmalted barley that defines the richness and complexity of Irish Pot Still Whiskey, making it a unique spirit within the category of straight whiskies.
