Plant Codex
One page per plant: binomial, part used, yield range, run time, harvest window, and the mistake most people make with it.

Why it exists
These are the questions new owners email us most. Each one has a place in the Archive.
The Run Calculator gives the charge weight and water fill for your still size, plant and mode.
The Codex chapter on reading the run, plus head temperatures in the Temperature Reference.
Every Plant Codex datasheet carries a sourced yield range, not a single hopeful number.
First Five Runs walks you from the citric wash to your first oil, and the video tutorial shows the first run on screen.
The US Legal Primer has a page for every state, cited to the statute, with a second volume for other countries.
The Cooling Water guide shows the pump and iced-water setup, with a hose diagram and what to buy.
A real example
Tell the Run Calculator you have 2 kg of fresh lavender and it returns the plan for the whole session.
Yields are ranges from published literature, and real runs often land in the lower half. Nine modes, 42 plants, three still sizes, or enter a custom size.
Look inside
One page per plant: binomial, part used, yield range, run time, harvest window, and the mistake most people make with it.
Thirty-six cards with exact charges, ratios and temperatures, from lavender hydrosol to a gin bill builder. Print one and keep it at the workbench.
Federal law and all fifty states, each cited to the statute, so you know what you may distil before you start.
Sourced, not guessed. CRC Handbook 102e · NIST WebBook · Lawrence · Tisserand & Young · Guenther · ISO standards
The full contents
The reference library for anyone who owns a copper alembic, or is about to.
The Distiller's Archive is the library we wished existed when we sold our first still: what to do on the first evening, how to keep the condenser cold, how much plant goes in the pot, what the dial should read, what yield to expect, and what the law says where you live. Twelve parts, one payment, and it opens in your CopperHolic account the moment you order.
Every boiling point from the CRC Handbook 102e and NIST WebBook. Every yield range from peer-reviewed literature (Lawrence, Tisserand & Young, Guenther, ISO standards). Every legal citation to the statute itself. Ranges where ranges are honest, because single numbers lie.
Scaled tables and calculator presets for the CopperHolic 5 L, 5-gallon and 10-gallon alembics. Own a different pot still or alembic? The manual, plant data, recipes and legal primers apply to any of them, and the calculator takes a custom size.
