Cicerone Certified Beer Server Practice Exam

Which of the following is a trait of an Imperial Stout?

1. Assertive roast flavor

2. High, effervescent carbonation

3. Low perceived bitterness

4. Moderate buttery flavor

The correct answer is: Assertive roast flavor

An Imperial Stout is characterized by its robust and assertive roast flavor, which stems from the use of a high proportion of roasted malts. This trait contributes to the beer's deep, dark color and complex flavor profile, often featuring notes of chocolate, coffee, and dark fruits. The prominence of these roasted characteristics is what distinguishes Imperial Stouts from lighter styles. The other choices do not align with the typical attributes of an Imperial Stout; for example, while some carbonation is present, it is generally not described as high or effervescent. Additionally, Imperial Stouts typically exhibit a higher perceived bitterness due to the inclusion of more hops and roasted malts, contrasting the low perceived bitterness mentioned. A moderate buttery flavor, often linked to diacetyl, is usually not desirable in Imperial Stouts, which are lauded for their rich and bold flavors rather than any buttery characteristics.
