Where to Buy Wormwood: A Sourcing Guide for Distillers and Makers
Wormwood is an easy herb to buy badly. It is sold by the pound on marketplace sites and by the ounce in packets that never say what species is in the bag or what year it was cut. For a distiller building an absinthe, a vermouth maker balancing a bitter backbone, or a herbalist making a digestive formula, those two facts decide what ends up in the glass. This guide covers what to look for before you buy, how much you actually need, and how to keep it once it arrives.
We grow both wormwood species on our certified Organic farm in Charlevoix, Québec, and most of what we cut goes directly to distilleries and small manufacturers. What follows is written from the supply side, and is mostly the answers to questions buyers ask us every season. If you would rather grow your own, our guide to growing wormwood for homemade absinthe covers cultivation, harvest timing, and how the herb works in the still.
First, Which Wormwood Do You Need?
Two different plants get sold as wormwood, and buying the wrong one is the most common and most expensive mistake. Artemisia absinthium, called grand or common wormwood, is the bitter, silver-leaved species that goes into the initial maceration and distillation. It is what a recipe means unless it says otherwise. A third plant, Artemisia vulgaris or mugwort, is sometimes shelved alongside them and is a different herb entirely.
Artemisia pontica, Roman wormwood or petite absinthe, is smaller and more delicate, and is used in the post-distillation colouring step rather than the still. It will not give you the bitterness a formula is asking for, so it is a companion to grand wormwood and not a substitute. If you are making a verte absinthe you want both, in quite different quantities, which is why our Roman wormwood is sold separately.
What Good Dried Wormwood Looks Like
You can judge a batch before you use it, mostly with your eyes and nose. Well-dried wormwood is a bright silver-green, closer to the colour of the living plant than to hay. Grey, brown, or dusty material has usually been dried too hot, stored too long, or both. Colour is the most reliable tell, and it is the one thing a photograph on a listing will show you.
Then look at structure and smell. Good material holds recognizable leaf and soft stem rather than collapsing to powder at the bottom of the bag, and it should smell clean and resinous with an obvious bitter edge. Fine dust and a flat, musty smell tell you the same story: the volatile aromatics have gone. Finally, ask two questions a good supplier answers without hesitating. What species is it, and what year was it cut. If you need Organic certification on your own label, confirm it rather than assume it.
How Much Wormwood Do You Actually Need?
This is the question we field most often, and the honest answer is that published recipes vary more than you would expect. For absinthe, traditional maceration rates cluster around twenty to twenty-six grams of grand wormwood per litre of finished spirit, though home-distilling formulas range considerably higher. Vermouth recipes typically call for something between a quarter teaspoon and a teaspoon of dried wormwood per batch, since the herb is there for backbone rather than dominance. Bitters sit in between, with one widely circulated formula using roughly twenty-two grams in just under four litres of whiskey.
What that means in purchasing terms is that wormwood goes further than most herbs. A 50 g bag is enough for a couple of litres of absinthe or a long run of vermouth experiments, and a 1 kg bag is a season's supply for a small distillery. Buying a large quantity of an aromatic herb you will use a spoonful at a time is usually a false economy, because the last of it will have faded before you reach it.
Form and Storage
For maceration and infusion, whole or lightly cut aerial parts are the right choice. They give you the surface area you need, they strain easily, and they hold their aromatics far longer than ground material. Powdered wormwood has a place in capsule and tablet manufacture, but for anything going into alcohol it is harder to filter and it stales quickly. We sell ours as dried aerial parts, leaf and soft top stem, because that is the form our distillers ask for.
Stored well, wormwood keeps its character for about a year, and loses it quickly when it is not. Keep it airtight, in glass or a sealed bag, away from light and heat: a cupboard rather than the shelf above the stove, and not a clear jar on a sunny counter however good it looks there. If you are buying for a season rather than a batch, buy the size you will work through and let the supplier keep the rest in the field until next year.
How We Grow and Dry Ours
We grow both species in Charlevoix, Québec, where the mountain-cool climate and short, intense season seem to suit the plant. We cut just before flowering, when essential-oil concentration peaks, and we cut in the morning once the dew has dried. The material then goes onto screens and dries at 35 to 40°C with plenty of airflow and as little heat as we can get away with. That step is what decides whether you end up with silver-green leaf or grey dust.
It is garbled and packed on the farm and shipped from the current year's harvest. Certified Organic by Ecocert Canada, single species, one farm. Our wormwood goes to distilleries near home in Charlevoix and as far as Virginia and Colorado, along with vermouth and bitters makers and herbal manufacturers.
Sizes and Wholesale
We sell Organic wormwood in sizes from 50 g to 1 kg through our farm shop, and Organic Roman wormwood separately in smaller seasonal batches. Larger orders ship up to 12 kg in a single box. For bulk and wholesale orders, or for 5 kg and up, please contact us and we will confirm pricing and timing.
A Note on Safety
Wormwood essential oil contains thujone, which acts on the nervous system as a GABA-A receptor antagonist and is neurotoxic at concentrated doses. Wormwood essential oil should never be ingested. The dried herb used at traditional rates in spirits and bitters is a different matter, and commercial alcoholic beverages are regulated accordingly: the European Union permits up to 35 mg/kg of thujone in Artemisia-species spirits, and the United States treats "thujone-free" as under 10 ppm.
Wormwood is contraindicated in pregnancy and breastfeeding, for people with seizure disorders, and for young children, and it warrants caution alongside anticonvulsants and other medication acting on the central nervous system. This applies to both species. Roman wormwood is sometimes marketed as thujone-free, but published chemistry shows variable thujone content across batches, so treat them the same way. Speak with a qualified healthcare provider before using wormwood therapeutically.
Frequently Asked Questions
How do I know if dried wormwood is fresh?
Colour first: it should be a bright silver-green rather than grey or brown. Then structure, with recognizable leaf rather than powder. Then smell, which should be clean, resinous, and clearly bitter. A supplier who can tell you the species and the harvest year is generally a supplier worth buying from.
How much wormwood do I need for a batch of absinthe?
Published recipes vary, but traditional maceration rates cluster around twenty to twenty-six grams of grand wormwood per litre of finished spirit, with some home-distilling formulas going higher. A 50 g bag covers a couple of litres comfortably.
How long does dried wormwood keep?
About a year when it has been dried at low temperature and stored airtight, away from light and heat. Buy the quantity you will actually use within that window rather than stocking up.
Do you ship wholesale quantities?
Yes. Orders ship up to 12 kg in a single box, and for bulk, wholesale, or 5 kg-plus orders we set things up directly. Contact us with the species, the quantity, and your timeline.
