Myth Dark Sour takes the brand's Dark Spiced cane spirit and builds a rum sour around it, adding apple and orange juice from concentrate alongside citric and malic acids to create the characteristic sweet-sour contrast. The result pours deep amber-orange with a light fizz. Burnt sugar and dark cane warmth come through on the nose alongside apple juice and a faint treacle note. On the palate the sour template plays out clearly: the sweet molasses base is immediately cut by bright apple and orange, then the citric acidity sharpens the finish into something properly tangy. The balance leans tart rather than sweet, which keeps it interesting over a full can. No preparation needed: serve over ice or drink straight from the can. It does what a good rum sour should without you needing to make one.
