résidu de distillation


Les spent lees désignent le résidu de distillation qui subsiste au fond de l’alambic de deuxième distillation (spirit still). Titrant moins de 1% vol., les spent lees sont généralement traitées avant rejet.

La distillation produit deux types différents de déchets, techniquement désignés sous le terme de coproduits : le pot ale, littéralement bière d’alambic, résulte de la première distillation, les spent lees, c’est-à-dire lies épuisées ou vinasses, issus de la seconde distillation.

Meanwhile, pot ale and spent lees, both by-products of distillation, are treated to remove any toxic levels of copper and other substances, then re-released into a body of water big enough, and sufficiently fast-flowing, to receive them without suffering any damage.
