Which style typically has an IBU of 40-70?

In the context of Indian Pale Ales, an International Bitterness Unit (IBU) range of 40-70 is characteristic of the hoppy and bitter profiles that define these styles. The American IPA is known for its pronounced hop character, and the IBU levels typically fall within the higher end of the scale, often reaching or falling within this range due to aggressive hop additions during the brewing process.

Rye IPAs, while they include rye malt that adds a distinctive spiciness, also embrace the same hop-forward characteristics, therefore sharing similar IBU levels with American IPAs. Brown IPAs represent an intersection between traditional IPA and brown ales, maintaining some hop bitterness while integrating malt complexity, which can still lead them to achieve a comparable IBU range.

As such, the answer encompasses all these styles, affirming that they can all typically exhibit an IBU level within the range of 40-70, showcasing the versatility and hop-centric nature of IPAs and their variations.
