Which of the following is NOT a Saazer type hop?

Centennial is not a Saazer type hop, making it the correct answer to this question. Saazer types are traditionally associated with the Saaz hop, which originates from the Czech Republic and is characterized by its mild, earthy, and herbal aroma profile.

Spalt, Saaz, and Tettnang all belong to the same group of noble hops known for their lower bitterness and aromatic qualities. These hops are commonly used in German and Czech lagers, contributing to the delicate flavor and aromatic profiles that define these styles.

Centennial, on the other hand, is classified as an American hop variety. It is primarily used in American pale ales and IPAs and is known for its higher alpha acid content, offering a more pronounced citrus and floral aroma, which diverges from the characteristics of Saazer type hops. Therefore, recognizing the distinctive profiles associated with hop varieties helps differentiate Centennial from the noble hops like Saaz, Spalt, and Tettnang.
