hopIQ found 10 beers with the same hoppy and citrusy character as 2x4. Melvin's legendary flagship and self-proclaimed 'best damn DIPA in the world.' An absurdly hopped imperial IPA layered over a light malt base, with notes of pine, citrus, and tropical fruit. Winner of GABF Gold (2012), back-to-back Alpha King Championships, and World Beer Cup Gold. Ranked by flavour match rather than popularity.
