How to make an oxymel, plus a fire cider recipe

Here for fire cider? Jump to the recipe. If you’ve ever stirred honey into vinegar, you’ve already made a simple oxymel. The name comes from ancient Greek — oxy (vinegar) plus mel (honey) No fancy equipment needed, just pantry staples and a little patience.

An oxymel is an herbal preparation made with vinegar and honey instead of alcohol. The vinegar draws out the plant’s flavor while the honey balances the tang. You get a sweet-tart way to enjoy herbs. Honey isn’t for babies under 1 (see the honey note).

Ingredients

Just three things:

Dried herbs only

Fill the jar about 1/4 full with dried herbs. They’ll expand as they absorb liquid. See our herb drying guide.

Our advice: the oxymel methods here are for dried herbs only. Fresh herbs, citrus peel, garlic, and other fresh produce go in the fire cider method. It heats the vinegar, following University of Minnesota Extension’s steps.

Two ways to make it

Cold method (traditional)

This is the traditional way. It takes longer, and the honey stays raw.

  1. Put your dried herbs in a clean jar, about 1/4 full.
  2. Pour apple cider vinegar over the herbs until it covers them by 1–2 inches.
  3. Add honey to fill the jar, leaving about an inch of headspace at the top. Start with equal parts vinegar and honey.
  4. Stir well with a wooden spoon or chopstick. The honey will be thick at first.
  5. Cover with a plastic lid, or put parchment paper between the jar and a metal lid so the vinegar doesn’t touch the metal.
  6. Label with the date and ingredients. Store in a cool, dark cupboard.
  7. Shake it every few days. Let it sit for 2–4 weeks.
  8. Strain through cheesecloth, pressing the herbs to get all the liquid out.
  9. Taste and adjust (see flavor).
  10. Pour into clean bottles, label, and refrigerate (see storage).

Warm method (when you’re in a hurry)

Gets the job done in a day. Only the vinegar is warmed; the honey goes in after it cools. This is for oxymels. Fire cider uses its own hot-vinegar method, below.

  1. Combine dried herbs and vinegar in your jar.
  2. Set the jar in a pot of warm water (like a double boiler). Our advice: keep it under 110°F for 1–2 hours, and don’t let it boil.
  3. Cool completely, then strain.
  4. Mix in equal parts honey.
  5. Bottle, label, and refrigerate (see storage).

Our advice: for tough roots or seeds, try the warm method. For delicate flowers and leaves, stick with cold.

Getting the flavor right

Our advice: start with equal parts vinegar and honey by volume. That’s your baseline. From there:

  • Too sour? Add more honey, a spoonful at a time
  • Too sweet? Add a splash more vinegar
  • For a sweeter taste, use 2 parts honey to 1 part vinegar
  • Want more herb flavor? Pack more herbs in next time

Stir a spoonful into warm water or tea, or use it in salad dressing.

Storage and shelf life

Our advice: keep oxymels in the fridge, in clean, dry glass jars. Label each one with the ingredients and date, and taste it before you use it. Dark amber glass is nice, but any glass jar works.

Clemson Extension says “properly prepared and bottled” flavored vinegars keep “for up to three months in cool storage,” and that refrigeration “may extend the quality for six to eight months” (Clemson). Those figures are for heated flavored vinegars made without honey, so they don’t cover oxymels.

When to toss a jar: “If a flavored vinegar ever has mold on or in it, or signs of fermentation (bubbling), cloudiness or sliminess, throw it away without tasting or using any of the vinegar for any purpose” (Clemson).

Oxymel safety notes

These notes are about taking oxymels, not growing these plants.

Honey and babies

“Do not feed honey to a child who is younger than 1 year old” (CDC). So no oxymel or honey-sweetened fire cider for babies.

Vinegar, pregnancy, and plant ID

Our advice:

  • Use vinegar labeled 5% acidity.
  • Pregnant or nursing? Check with your healthcare provider about specific herbs.
  • Use only plants you can positively identify as safe and edible.

Troubleshooting

Separation? Normal. Just shake before using.

Too thick? Your honey might have crystallized. Warm the bottle in hot water to thin it out.

Fermentation bubbles? Throw it out (see storage).

Tastes off? When in doubt, throw it out.

Two starter recipes

Thyme oxymel

Fill jar 1/4 with dried thyme. Cover with vinegar plus 1–2 inches, then add equal parts honey. Follow cold method instructions above. Thyme grows well in a 6–8 inch pot: start your first herb garden.

Elderberry oxymel

Always cook elderberries. NCCIH says raw or unripe elderberries contain “poisonous cyanide-producing substances” (NCCIH).

Fill jar 1/4 with dried elderberries. Cover with vinegar plus an inch. For this one, skip the cold method. Our advice: simmer the berries and vinegar gently for 30 minutes (a flavor step, not a safety minimum), then cool, strain, and mix with equal parts honey. Growing your own? See how to grow and harvest elderberry safely.

Fresh lemon peel, garlic, or herbs? See dried herbs only.

Quick reference card

Basic oxymel formula:

  • Herbs (1/4 jar dried)
  • Cover with vinegar + 1–2 inches
  • Add equal parts honey
  • Shake, wait 2–4 weeks, strain
  • Stir a spoonful into tea or dressings

That’s all there is to an oxymel. The vinegar and honey do most of the work — you just have to give them time. Want a spicier jar with fresh produce? Fire cider, next, takes a few more steps.

Fire cider recipe: a spicy honey-vinegar oxymel

“Fire cider is a flavored vinegar made from infusing apple cider vinegar with onions, garlic, ginger and citrus fruit” (University of Minnesota Extension). Sweeten it with honey after straining, and it becomes an oxymel too.

Fire cider ingredients

Common picks, each from its own source:

Our advice: choose your own mix, with no set amount for each. Keep the total to the card’s ratio.

Want less heat? Capsaicin, the chemical that makes peppers hot, “is concentrated in the membranes and seeds,” and removing some or all of them adjusts the heat (Penn State Extension).

Handling horseradish and hot peppers safely

Do this before you start slicing.

Hot peppers

From Poison Control:

  • Air: “Open the windows or use fresh air if preparing or cooking hot peppers.”
  • Skin: “During meal preparation, if capsaicin-containing oils get on the skin, it can lead to pain and redness with irritation.”
  • Eyes: “If the eye has been affected, irrigation with copious warm water for 15 minutes is the first step.”
  • Help: call your poison center at 1-800-222-1222 or use webPOISONCONTROL. Call 911 for any trouble breathing or chest discomfort.

Horseradish

  • Fumes: horseradish root “contains oils that can irritate your sinuses and make your eyes water” (Cleveland Clinic).
  • Contact: “Direct application to the skin or eyes may cause irritation and burning” (PeaceHealth).
  • Our advice: grate horseradish near an open window or outdoors, keep your face back from the grater or food processor, and wear gloves.

How to make fire cider, step by step

Steps 1 to 6 follow Minnesota Extension’s guidance. Steps 7 and 8, and anything marked “our advice,” are ours.

  1. Clean and sanitize. Start with a clean kitchen. Sanitize your counters, cutting boards, and utensils.
  2. Wash and slice thin. Wash the produce under clean running water. Slice it thinly into a sanitized jar, using the card’s ratio, and don’t overpack the jar. Our advice: wear gloves for the peppers and grate the horseradish with care, as above.
  3. Heat the vinegar. Bring it to just below boiling (190–195°F), then pour it over the produce.
  4. Check the temperature. The whole mixture, including the center of the solids, has to stay above 165°F for at least 1 minute 12 seconds. Check it with your thermometer. Minnesota Extension notes that thin slices and a loosely packed jar make that temperature easier to reach.
  5. Lid and steep. Put on a clean lid and rest the jar in a cool, dark place for 10 to 30 days. The longer it steeps, the stronger the flavor. Our advice: use a plastic lid, or parchment under a metal one, as in the oxymel method.
  6. Strain. Strain out all the solids. A coffee filter catches small particles.
  7. Sweeten (our step). Stir in honey to taste.
  8. Bottle, label, refrigerate (our advice). Write the ingredients and date on the label, then keep the jar in the fridge.

Minnesota Extension also lists hot water bath, hot-fill hold, and cold-fill hold bottling for fire cider, each tied to a measured pH. We don’t cover canning or pH testing here.

How to use fire cider

Splash it into warm water or apple cider, stir it into a salad dressing, or drizzle it over cooked vegetables or soup. Those serving ideas come from the Omega Institute’s recipe.

Minnesota Extension’s fire cider page gives no serving amount, so we don’t give one either. Our advice: it’s sharp and spicy, so start with a small splash in food or a drink.

How long fire cider lasts (and whether to refrigerate it)

Keep it in the fridge (step 8) and taste it before each use.

“After bottling, fire cider should be stored in a cool and dark location. Once opened, it must be refrigerated” (Minnesota Extension). Minnesota Extension’s storage advice is for jars bottled with its pH-tested methods, which we don’t cover.

Minnesota Extension gives no shelf life for fire cider. For Clemson’s flavored-vinegar figures and their limits, see storage.

How to tell it’s gone bad: “If mold, bubbling or cloudiness appears, your vinegar has spoiled and should be discarded” (Minnesota Extension).

Fire cider safety notes

These notes are about taking fire cider, not growing these plants.

  • Horseradish: PeaceHealth says: “Horseradish should be avoided by people with hypothyroidism, gastritis, peptic ulcer disease, and kidney disorders.” Citing the German Commission E monographs, it adds: “Horseradish should not be used by women during pregnancy or breast-feeding or by children under four years of age.”
    • Our advice: if you have a thyroid condition, gastritis, a stomach or duodenal ulcer, or a kidney condition, if you’re pregnant or breastfeeding, or if the fire cider is for a child under 4, leave out the horseradish or skip fire cider. Ask your doctor or pharmacist first.
    • Cleveland Clinic dietitian Amanda Igel advises caution with inflammatory digestive conditions such as Crohn’s disease, esophagitis, inflammatory bowel disease, ulcerative colitis, and stomach ulcers. Her rule of thumb: “If you get too much stinging in your mouth, nose, stomach or throat, give it a break” (Cleveland Clinic).
    • We looked for more horseradish safety guidance and found none: NCCIH’s herb index has no horseradish entry, EMA’s herbal medicines list has none, and we found no horseradish page at Memorial Sloan Kettering’s About Herbs.
  • Hot peppers: “too much hot pepper can result in nausea, vomiting, abdominal pain, diarrhea and a burning sensation when ingested” (Poison Control).
  • Garlic: “Taking garlic supplements may increase the risk of bleeding” (NCCIH). That warning is about garlic supplements.
  • Ginger: “Ginger can have side effects such as abdominal discomfort, heartburn, diarrhea, and mouth and throat irritation when taken orally” (NCCIH).
  • Medicines: “If you take any type of medicine, talk with your health care provider before using ginger or any other herbal products; some herbs and medicines interact in harmful ways” (NCCIH).
  • Honey: not for babies under 1 (honey note).
