The oldest distillation apparatus anyone has excavated was not built to make anyone drunk. Terracotta vessels from Tepe Gawra in Mesopotamia, dated to the Middle Chalcolithic, roughly 4200 BCE, show a simple perforated chamber resting above a boiling vessel, a design meant to capture volatile aromatic compounds, perfumes and essential oils drawn out of plant material by heat, not spirits meant for drinking. That apparatus evolved on the same site into a more refined channeled-rim design, vessels of that later kind spanning down to about 3500 BCE, for the same purpose. Separately, and on the far side of Eurasia, a different distillation method entirely was already in use by the first century BCE in China, Mongolia, India and South America. Put those threads together and a genuine gap opens up: distillation apparatus is very old, its use for perfume and medicine is well attested very early, and yet the specific moment someone first pointed a still at wine or beer with the deliberate goal of making a stronger drink, rather than a scent or a remedy, is not pinned down by any of this evidence. It is a real open question in the field, not a gap in this atlas's research, and it is the kind of question a single well-dated residue, chemical traces of ethanol rather than aromatic oils in an early enough vessel, could genuinely settle.
