Under 5%

Low-alpha hops (typically under about 5%) deliver gentle bitterness and shine for late additions, whirlpool, and dry hop where aroma matters more than IBU load. This range is classic for noble and traditional aroma varieties.

Expect soft, refined character from hops like Czech Saaz, Hallertau, Hersbrucker, German Tettnang, UK Fuggle, UK Kent Goldings, Willamette, Mt. Hood, Styrian Celeia, Crystal, and Cascade when you want subtle bitterness without overwhelming the malt.
