Hookah-Hookah Watermelon tastes like watermelon. This, however, is important—where most brand’s watermelon flavors are a Bubbleyum caricature of the real melon, Hookah-Hookah’s watermelon is actually hyper-realistic. The flavor is sweet, but not candy sweet. The flavor is a mix of the sweet, bright pink parts of a real watermelon, as well as the more bitter, lighter colored parts found closer to the rind.
