Course Welcome — What You'll Build

Welcome to the intermediate tincture course. By the end of the twelfth lesson you will have three finished liquid extracts on your shelf — a 1:5 dry-plant weight-to-volume tincture, a percolated extract, and a double extract — each made with the chemistry-first reasoning that separates a craft herbalist from someone who follows recipes.

What "intermediate" means here Beginner work is correct. You filled a jar with chopped plant, topped it with vodka, shook it for four weeks, strained it, and it worked. That is not nothing — folk-method tinctures have kept families well for centuries and they will keep you well for the rest of your life. What changes at the intermediate tier is replicability. When you make a chamomile tincture today and it nervinely settles a child, and you make it again next year with a different harvest and it does nothing, you will want to know why. Intermediate practice is the difference between "I think this works" and "I know this works because I made it the same way." It is also the foundation for ever sharing your work — gifting, trading, or eventually selling — in a way that does not put anyone at risk.

Materials you will need across the course Plan to acquire, if you do not already have them: a kitchen scale that reads to 1 gram (0.1 gram is better), a 100-milliliter graduated cylinder, several 500-milliliter wide-mouth glass jars with tight-fitting lids, a few amber 1-liter jars for finished extracts, cheesecloth and unbleached muslin, a French press or potato ricer (poor man's tincture press), a coffee filter or two, a glass funnel, a Pyrex measuring jug, and labels you can write on with permanent marker. You will also need 95% grain alcohol (Everclear 190 proof) — if you live in a state that restricts it, 151 proof will work for most lessons; we will address the math when it matters. For lesson eight, you will build a simple percolation cone from a 1-liter glass jar — instructions are inside that lesson.

The lab notebook habit The single most useful change you can make at this level is to write everything down. Date, plant, source, part used, dry or fresh, weight to the gram, menstruum used, alcohol percentage, ratio, jar size, expected yield, date pressed, date settled, date bottled, final volume, organoleptic notes (color, clarity, smell, taste). Six months from now you will be glad. Two years from now your notebook will be the most valuable thing on your shelf. Set up the first page now as a master index, and number each batch sequentially.

Plants we'll work with The course uses three plants as case studies because each one teaches a different lesson. Ashwagandha root (Withania somnifera) — an alkaloid- and glycoside-bearing root that wants a moderate-alcohol menstruum, behaves predictably, and forgives small math errors. Hawthorn flower-and-leaf or berry (Crataegus monogyna / oxyacantha) — gentle, water-soluble flavonoid chemistry that teaches you when high alcohol is wrong. Reishi mushroom (Ganoderma lucidum) — the classic case for a double extract, where alcohol and water each pull half the medicine. You can substitute regional alternatives — astragalus for ashwagandha if it suits your practice, motherwort for hawthorn, turkey tail for reishi — but the three I have named will move you through every lesson smoothly.

What you carry forward Every choice you make from here forward should be defensible. If a colleague asked you "why 60% alcohol and not 70?" or "why did you macerate for three weeks rather than six?" you should have an answer that begins "because the chemistry of this plant…" rather than "because the recipe said so." That is the bar. Let's get to it.
