Which of the following beers is known for its high IBU of 60-120?

Pliny the Elder, a double IPA from Russian River Brewing Company, is renowned for its high IBU (International Bitterness Units) level, typically falling within the range of 60-120. This characteristic is key to its identity as a strong, hop-forward beer, emphasizing both bitterness and the aromatic qualities of the hops used in brewing.

The bitterness in Pliny the Elder stems from a significant addition of hops both during the boil and in the dry-hopping process, showcasing a variety of hop profiles that contribute to its complex flavor and aroma. This aligns with the typical attributes of double IPAs, which are known for heightened bitterness as well as a robust hop presence.

The other options do not fit into the same IBU range as clearly. Chiltern White IPA, while possibly bitter, does not reach those levels commonly associated with double IPAs. Boulevard Harvest Dance is a seasonal beer that may exhibit balance but does not focus on the extreme bitterness. Rodenbach Grand Cru, a Flanders red ale, is known for its sour and tart characteristics rather than bitterness, making it significantly lower in IBU.
