Which beer has an IBU range of 20-30?

Belgian Pale Ale is characterized by its moderate bitterness, which typically falls within the IBU range of 20-30. This range allows the beer to exhibit a pleasant balance between the sweetness of the malt and some hop character, making it suitable for the style. The hop profile in a Belgian Pale Ale can contribute to floral and fruity aromas, which complement the yeast character commonly found in Belgian beers.

In contrast, the other styles listed, such as Belgian Tripel and Belgian Dubbel, generally have higher sweetness and often range above 30 IBUs due to their stronger malt backbone and complex flavor profiles. The Belgian Blonde Ale, while lighter, also tends to have a similar IBU range to the Pale Ale but can sometimes edge higher. Therefore, Belgian Pale Ale is the most fitting answer when considering its specific bitterness range.
