For Duvel Tripel Hop, the brewers do not simply add a third hop, but they apply the dry-hopping technique. This means that in addition to the standard hops during the brewing process, extra hop cones are added at a later stage of the brewing process (during maturation). This makes the hop aromas more intense and refined in the final beer. For Duvel Tripel Hop, they use aroma hop Citra as the third hop variety. This hop is grown in the Yakima Valley in Washington and enriches the flavor palette of Duvel with fresh notes of grapefruit and tropical fruit.
