Tinctures & Liquid Extracts: Intermediate Formulation
Move from "fill a jar, top with vodka" to pharmacopoeial-grade liquid extracts
Twelve lessons that take the folk-method tincture maker into precise liquid-extract territory. You will learn the chemistry behind menstruum choice, the math of weight-to-volume preparation, the difference between maceration and percolation, the special cases of glycerites, oxymels, and double extracts, and how to label and store a finished apothecary so the work you do today still serves you in five years.
Taught by Deidre Starner, Master Herbalist
What you'll learn
- Choose an appropriate menstruum (solvent system) for any plant by matching its dominant constituent chemistry
- Calculate a weight-to-volume tincture from scratch, including final alcohol percentage after accounting for plant moisture and marc absorption
- Run a percolation cone end-to-end and judge completion by sensory and volumetric quality markers
- Produce double extracts for mushrooms and resinous plants, and lower-alcohol glycerites and oxymels for clients who cannot tolerate alcohol
- Label, store, and assess shelf life of a finished apothecary to a standard that would not embarrass you in front of a clinical reviewer
