Either is correct. It’s possible the word is derived from the Arabic al-anbīq – a combination of the Arabic article al with the Greek word ambikos, meaning bowl. The term was later adapted to Latin as alembicum, to be slightly changed in the 14th Century to middle French as alambic. Whether you use Alembic or Alambic, what we know from experience is that its the best pot still for distilling flavorful spirits.
