What is the characteristics of the IBU for an American Amber Ale?

The correct range for the International Bitterness Units (IBU) in an American Amber Ale is 25-40. This style typically showcases a balanced profile where the malt sweetness is prominent, complemented by hop bitterness that does not overshadow the malt character. The IBU range reflects a moderate level of bitterness, allowing the rich caramel and toasty malt flavors to be prominent while providing enough hop presence to create balance.

The other options suggest higher bitterness levels that would be more characteristic of hop-forward beer styles such as IPAs or Imperial IPAs, where stronger hop flavors and aromas are central to the style. The specified range of 25-40 aligns closely with the intended flavor profile of American Amber Ales, reinforcing the importance of balance between malt and hops in this category.
