Sounds like my black IIPA I just brewed again. Basic IIPA grain bill (with 1 lb dehusked carafa 3 in there) with 1 oz each simcoe and citra at 20, 1 oz each amaraillo and cascade at 15, 1 oz simcoe and citra at 10, 1 oz amarillo and cascade at 5, 1 oz of all 4 at flameout, bitter with 1 oz magnum, yields just over 100 IBUs.
