Found on the periphery of evening gatherings, in hospital waiting rooms, and in the hands of the man who says he sleeps better these days. The cup of decaf presents itself with total confidence, same roast, same steam, same faint bitterness at the rim, and yet it withholds the one thing anyone actually came for. It has been to the factory and back, stripped of its caffeine by solvent or water or carbon, and returned to us wearing the same coat as before, a kind of witness protection for beans.
Its habitat is the second cup, the one poured after nine p.m., or the first cup for those who have made peace with something. Behavior is notably calm; it does not jitter the hand or quicken the pulse. Distinguishing features are nearly nonexistent, which is itself the distinguishing feature; connoisseurs claim they can taste the void, though blind trials suggest otherwise. Field notes from long observation: the cup of decaf is often ordered apologetically, as though admitting a small defeat to the barista, who nods without judgment, having poured a thousand of these into a thousand quiet resignations. It asks to be enjoyed for its own sake, warmth, aroma, the small ceremony of the mug, and mostly, we let it.
