Which type of Irish whiskey is made from multiple grains and can include caramel color?

The correct choice is Irish Single Grain Whiskey. This type of Irish whiskey is produced using a grain mix that can include ingredients beyond just malted barley, such as corn or other grains. A distinctive feature of Irish Single Grain Whiskey is the possibility of the inclusion of caramel coloring, typically used to enhance its appearance and give it a consistent color profile.

Irish Single Grain Whiskey is generally lighter and smoother than other types of whiskey, partly because of the continuous column distillation process often used in its production, which can refine the spirit and contribute to its approachable flavor.

In comparison, Irish Single Malt Whiskey is exclusively made from malted barley and distilled in pot stills, while Irish Pot Still Whiskey must contain a mix of malted and unmalted barley, creating different flavor profiles that do not include the broader grain options found in single grain. Blended Irish Whiskey combines both single malt and single grain whiskeys, which can include caramel coloring, but it is not specifically categorized under one grain type. Thus, each type of whiskey has distinct qualifications that make Irish Single Grain Whiskey the best answer to the question.
