What characteristic distinguishes a Brown Ale from an IPA?

The characteristic that distinguishes a Brown Ale from an IPA is malty sweetness. Brown Ales are typically brewed with darker malts, which impart a rich, sweet, and nutty flavor profile. This sweetness is a defining trait of Brown Ales, balancing any bitterness from the hops and resulting in a smoother, fuller mouthfeel.

In contrast, India Pale Ales (IPAs) are known for their prominent hop flavors, which often translate into higher bitterness levels, making them distinct from Brown Ales. While IPAs can also have strong flavors and fruity notes due to the hops used, these characteristics are not what sets Brown Ales apart. Thus, the emphasis on malty sweetness in Brown Ales is a key distinguishing factor in the comparison between these two beer styles.
