How to Make a Herbal Tincture: Proof and Ratios

The quick answer

A tincture is plant material steeped in alcohol — technically a maceration. Strength follows the material: roughly 80 proof (40% ABV) for dried leaves and flowers, 120–140 proof (60–70%) for fresh plants that bring their own water, 140 proof and up for roots, bark and seeds, and 180 proof and up for resins. A reliable base ratio is 1 part plant material to 5 parts alcohol by weight. Steeping runs two to four weeks for soft material and four to six for hard, kept dark and cool and shaken once a day. Then strain through cloth, press well, bottle in dark glass and label it. Use drinking alcohol only — never denatured alcohol or rubbing alcohol. This describes a preparation method. It contains no dosage guidance and no health claims.

What a tincture actually is

The process is called maceration: plant material sits in a solvent and gives up its constituents. Water dissolves only part of what is there — sugars, mucilage, some acids. Alcohol dissolves considerably more, particularly essential oils, resins and bitter compounds. That is why alcohol is the solvent of choice when you want the fuller spectrum of a plant in the jar.

The second reason is more mundane and at least as important: alcohol preserves. From roughly 20% in the finished extract, bacteria and mold no longer multiply. A cleanly made maceration, stored dark and cool, keeps for years — which is the real argument for tincturing rather than drying. Dried material fades over months; a tincture holds.

Proof, ABV, and why American labels confuse this

Most herbal instructions are written in percent ABV. American bottles are labeled in proof, which is simply double the ABV. Vodka at 80 proof is 40% alcohol. Grain spirit at 190 proof is 95%. Getting this backwards is the single most common way a batch fails before it starts.

Material	Alcohol	Steeping time
Dried leaves, flowers, herb	about 80 proof (40%)	2–4 weeks
Fresh leaves, flowers, herb	about 120–140 proof (60–70%)	2–4 weeks
Roots, bark, seeds	140 proof and up (70%+)	4–6 weeks
Resins	180 proof and up (90%+)	4–8 weeks
Very soft, aromatic parts	80–120 proof (40–60%)	1–2 weeks

The logic is straightforward. Fresh plants carry their own water and dilute the alcohol, so you start higher. Hard, dry parts release their constituents reluctantly and need a more aggressive solvent.

In practice: plain 80-proof vodka is right for dried material and is the easiest thing to buy. For fresh material and roots you want high-proof grain spirit. Note that its availability is a state-by-state matter in the US — the 190-proof grade is restricted or unavailable in a number of states, where 151 proof is sold instead. If you can only get 151, use it for fresh material and accept a slightly lower final strength; do not try to compensate by adding less plant.

Never use denatured alcohol, methylated spirits, rubbing alcohol or isopropyl. These contain additives specifically intended to make them undrinkable, and some are toxic. There is no "just a little" version of this rule.

The ratio and the process

The working base ratio is 1 part plant material to 5 parts alcohol by weight — so 20 g of dried herb to 100 g of alcohol. With fresh material, which is bulky, most people work by eye instead: fill the jar loosely without packing it, then pour in enough alcohol to cover everything by about an inch.

1. Chop. Small enough that the solvent reaches all of it. Roots and bark want to be genuinely small.
2. Combine. Fill the jar, pour over, keep everything submerged. Anything above the surface will mold and spoil the batch.
3. Steep. Dark, cool, shaken once daily. The daily shake is not superstition — it moves saturated solvent away from the plant surface.
4. Strain. Through cloth, and press the material out properly. A surprising share of the extract is still in the spent material.
5. Bottle and label. Dark glass. Plant, alcohol strength, date, ratio. Every time.

A wide-mouth canning jar is the ideal vessel: cheap, genuinely airtight, easy to fill and to empty. Make sure the lid does not have a bare metal underside in prolonged contact with high-proof alcohol.

The five mistakes that cost you the batch

• Material above the alcohol line. The commonest failure by far. Anything sitting proud of the surface will mold, and the mold will not stay local. Weigh the material down or top up the solvent.
• Alcohol too weak for fresh material. Fresh plants can easily be 70–80% water. Put them in 80-proof vodka and the finished extract may fall below the preservation threshold — which is how a jar ferments instead of macerating.
• Warm and bright storage. A jar on a sunny windowsill is a picture and a loss. Light and heat degrade exactly what you were trying to capture.
• Straining without pressing. Letting it drip through a cloth and discarding the material leaves a substantial fraction behind. Wring it out.
• No label. You will not remember. Six months on, a dark bottle of brown liquid is indistinguishable from any other dark bottle of brown liquid, and unidentifiable tinctures get thrown away.

Storage, shelf life, and knowing when it has gone

Dark glass, cool, closed. Kept that way, a properly strong maceration lasts years — the alcohol is doing the preserving.

Signs that something went wrong: visible mold or a floating film, cloudiness that was not there before, a fermented or vinegary smell, or noticeable pressure when you open it. Any of those means discard it. Do not attempt to strain a moldy batch and save the liquid.

Oil macerations are a different thing

Worth naming because the two get confused. If you steep plant material in oil rather than alcohol you get an infused oil, not a tincture, and the result differs in two ways: oil dissolves a different set of compounds, and oil does not preserve. Infused oils carry a genuine spoilage risk, especially with fresh material, and they keep months rather than years.

If you want a botanical preparation in oil without the maceration and the shelf-life management, a ready-made one is a reasonable shortcut — our Dragon's Blood ritual oil at $10.00 is a resin-based oil of exactly this type, and resin is the material class that is hardest to extract at home, since it needs the highest alcohol strengths in the table above. It is a ritual oil for anointing and dressing, not something to take internally. For making your own, see how to make anointing oils.

What we do not claim

This is a method, not medicine. We are not telling you that a homemade tincture treats, prevents or improves any condition, and there is deliberately no dosage guidance here. What a plant extract does in a body is a separate question that does not belong on this page and should be taken to a qualified practitioner.

Two safety points that do belong here. Only tincture plants you have identified with complete certainty — the identification rule from harvesting and drying herbs applies with more force here, because alcohol extracts efficiently, including from the wrong plant. And a high-proof tincture is a concentrated alcohol preparation: keep it out of reach of children, well away from open flame while you are working, and out of the house entirely if anyone in it is in recovery from alcohol use.

Frequently asked

Can I use rum, whiskey or brandy?

Yes, for dried material — they sit around 80 proof and work. They contribute their own color, sugar and flavor, which some people want and others do not. For anything needing higher strength they cannot reach it, so use neutral grain spirit there.

What if I can only buy 151 proof?

Use it. At 75.5% it comfortably covers fresh material, roots, bark and seeds. Only resins really want more. Do not dilute your plant-to-alcohol ratio to compensate — the strength matters more than the volume.

Does it have to be exactly 1:5?

No. It is a reliable starting point, not a law. Stronger ratios exist and so do weaker ones. What matters far more is that the material stays covered and the alcohol is right for the material. Record what you actually did so you can repeat or adjust it.

Why shake it every day?

Solvent immediately around the plant surface becomes saturated and extraction slows. Shaking redistributes it. Missing a day is not a problem; never shaking at all gives you a weaker extract for the same wait.

Is a glycerite the same thing without the alcohol?

Not the same, no. Vegetable glycerin extracts a narrower range of compounds than alcohol and preserves less reliably, so glycerites are weaker and shorter-lived. They exist for people avoiding alcohol entirely, but they are a compromise rather than a substitute.
