No, I admit I didn't have Ortolanus on my radar. My first thought was Rupescissa.

Abstract:
The quintessence was a key element in late medieval alchemy. I will discuss the origin of the concept from its vague beginnings in the 13th Century, well summarized by Restoro d’Arezzo (ca.1282), to the critical meeting in the early 14th century. I will focus my research on a treatise entitled Liber super textum hermetis (pre.1325) signed by an alchemist called Hortulanus (Jakob Ortlein of Nördlinger, probably a dominican monk). The full version consists of two sections. The first is a less-known guide to elaborate a pure quintessence or “Stone of Life”, which seems to be an alcoholic compound obtained by distillation and rectification of wine. Hortulanus thought of alcohol as the quintessence almost a quarter of century before John of Rupescissa’s book De quinta essentia. The second section of the Liber super textum hermetis is a popular commentary on the Emerald Tablet that usually circulated as an independent work.
