The style may use any variety of hops. Though the hop character is intense it’s balanced with complex alcohol flavors, moderate to high fruity esters and medium to high malt character. While hop character may be very intense, it may not be harsh in quality. Imperial or Double India Pale Ales have medium-high to full body. Diacetyl should not be perceived.
