The term “Imperial” in the context of beer refers to a style that is bigger, bolder, and stronger than the base style it is derived from. In the case of an Imperial IPA, it is a more intense and robust version of a traditional IPA (India Pale Ale).
The origin of the term “Imperial” in beer styles can be traced back to the British Empire and its history of exporting strong, hoppy ales to its colonies. These beers were brewed with higher alcohol content and extra hops to help preserve them during long journeys at sea. The term “Imperial” was used to denote these stronger versions of the original styles.
In the case of an Imperial IPA, the base style is the IPA, which is already known for its hop-forward flavor profile and higher alcohol content compared to other beer styles. An IPA typically showcases the hop bitterness, aroma, and flavor, with a balance of malt sweetness. However, an Imperial IPA takes these characteristics to the next level.
An Imperial IPA is characterized by a more pronounced hop bitterness, often with higher levels of hop aroma and flavor. The malt backbone is usually richer and more robust, providing a balance to the intense hop character. The alcohol content is also higher, often ranging from 7% to 10% or even higher, adding to the beer's overall strength and complexity.
The use of the term “Imperial” also implies a sense of grandeur and superiority. It suggests that the beer is a showcase of the brewer's skill and craftsmanship, pushing the boundaries of what is considered a standard IPA. It signifies a beer that is meant to be savored and enjoyed in smaller quantities, due to its higher alcohol content and more intense flavors.
Personally, I have had the pleasure of experiencing several Imperial IPAs throughout my career as a sommelier and brewer. One particular memory that stands out is trying a locally brewed Imperial IPA during a visit to a craft brewery. The beer had a striking golden color with a hazy appearance, indicating the generous amounts of hops used in the brewing process. The aroma was a burst of citrus, pine, and floral notes, showcasing the hops' aromatic qualities. Upon taking a sip, I was greeted with a powerful hop bitterness that lingered on the palate, balanced by a rich malt sweetness. The beer had a full-bodied mouthfeel and a warming sensation from the higher alcohol content. It was a truly memorable experience, highlighting the unique characteristics of an Imperial IPA.
To summarize, the term “Imperial” in an Imperial IPA signifies a beer that is a bigger, stronger, and more intense version of a traditional IPA. It is a style that pushes the boundaries of what is considered a standard IPA, with higher hop bitterness, more pronounced hop aroma and flavor, a richer malt backbone, and higher alcohol content. The term “Imperial” adds a sense of grandeur and superiority to the beer, reflecting the brewer's skill and craftsmanship in creating a beer that is meant to be enjoyed in smaller quantities due to its intensity.
