You can make lavender extract without alcohol using three common solvents: vegetable glycerin, a carrier oil, or vinegar. Each produces a different type of extract suited to different uses. Glycerin extracts (glycerites) are the closest substitute for alcohol-based tinctures and work well for culinary, skincare, and aromatherapy purposes. Oil infusions are ideal for topical use, and vinegar extracts fit into cooking and hair care. Here’s how to make each one.
Why Alcohol-Free Methods Extract Differently
Alcohol is such a popular extraction solvent because it dissolves a wide range of plant compounds, both water-soluble and oil-soluble. Lavender’s signature aromatic compounds are oil-soluble, and one of the key ones (linalyl acetate) is actually insoluble in glycerin. This means alcohol-free extracts will pull fewer total compounds from lavender. A study published in the journal Antioxidants compared lavender extracts made with different solvents and found that alcohol-based tinctures contained roughly double the total phenolic content of vinegar-based extracts. The antioxidant activity followed the same pattern.
That doesn’t make alcohol-free methods useless. It just means you should pick the right solvent for your purpose and set realistic expectations. Glycerin still captures enough aromatic and water-soluble compounds to produce a noticeably fragrant, flavorful extract. Oil pulls the fat-soluble aromatics effectively. And vinegar, while weaker in overall extraction power, creates a useful product with its own culinary advantages.
Glycerin Extract (Glycerite): The Best All-Purpose Option
A lavender glycerite is the most versatile alcohol-free extract. Vegetable glycerin is naturally sweet, shelf-stable, and safe to consume or apply to skin. When buying glycerin, look for one labeled USP grade and food grade. USP means it meets pharmaceutical quality standards, which ensures purity and safety whether you plan to eat it or use it topically.
What You Need
- Dried lavender buds: enough to fill a glass jar halfway when ground to a coarse powder
- Vegetable glycerin (USP, food grade): 3 parts
- Distilled water: 1 part
- A clean glass jar with a tight lid
- Cheesecloth or fine mesh strainer
Step-by-Step Method
Grind dried lavender buds into a coarse powder using a mortar and pestle, spice grinder, or even a ziplock bag and rolling pin. You don’t need a fine dust, just broken-up buds with more surface area exposed. Fill your jar about halfway with the ground lavender.
In a separate container, mix 3 parts vegetable glycerin to 1 part distilled water. For example, 1 cup glycerin to ⅓ cup water. The water is important: it thins the glycerin enough to penetrate the plant material and helps extract water-soluble compounds that glycerin alone would miss. Pour this mixture over the lavender until the herbs are fully submerged with 1 to 2 inches of liquid above them.
Seal the jar and store it in a cool, dark place. Shake it gently every day or two to keep the plant material coated and encourage extraction. Sources vary on timing: some recommend 1 to 2 weeks, others suggest 4 to 6 weeks for maximum potency. For lavender, 3 to 4 weeks is a reasonable middle ground that produces a well-scented, flavorful extract without the risk of off-flavors from over-steeping.
When it’s ready, strain through cheesecloth layered inside a fine mesh strainer. Squeeze the cheesecloth firmly to press out as much liquid as possible. If you want a clearer final product, strain a second time through a coffee filter, though this takes patience since glycerin moves slowly. Pour the finished glycerite into dark glass bottles (amber or cobalt) and store in a cool, dark place. It will keep for 1 to 2 years, compared to 4 to 6 years for alcohol-based tinctures.
Dried vs. Fresh Lavender
Dried lavender is the better choice for glycerites. Fresh lavender contains moisture that dilutes the glycerin and raises the risk of spoilage. Research comparing fresh and dried lavender extracts found that the drying method affects which beneficial compounds survive, with gentler drying methods preserving more antioxidant activity. If you’re drying your own lavender, hang bundles upside down in a warm, well-ventilated spot out of direct sunlight for 1 to 2 weeks rather than using high oven heat.
Oil Infusion: Best for Skin and Body Products
An oil-based lavender extract is ideal for lotions, massage oils, salves, and bath products. Since lavender’s aromatic compounds are oil-soluble, a carrier oil actually captures the scent quite well.
Choose a neutral, shelf-stable carrier oil. Olive oil, sweet almond oil, and jojoba oil are all common choices. Jojoba has the longest shelf life since it’s technically a wax ester. Fill a clean glass jar about one-third full with dried lavender buds (no need to grind them for oil infusions), then cover completely with oil, leaving about an inch of headspace.
Cold Method (Recommended)
Seal the jar and place it in a sunny windowsill or warm spot for 2 to 4 weeks. Shake it every few days. The cold method takes longer but preserves the oil’s quality and produces a cleaner lavender scent without the risk of cooked or bitter notes. Strain through cheesecloth when the oil smells strongly of lavender.
Warm Method (Faster)
If you need results sooner, place the sealed jar in a pot of water on the stove over the lowest possible heat for 2 to 4 hours. The water should be warm, not simmering. Overheating will cook both the oil and the lavender, creating off-flavors and degrading beneficial compounds. You can also use a slow cooker on its lowest setting with the jar sitting in a few inches of water.
Store finished lavender oil in dark glass containers in a cool place. Shelf life depends on your carrier oil but generally ranges from 6 months to a year. If it starts to smell rancid rather than floral, discard it.
Vinegar Extract: A Lighter Alternative
Vinegar extracts are the simplest to make and work well as culinary ingredients, hair rinses, and household cleaning additions. Apple cider vinegar and white wine vinegar are the most popular bases. The acetic acid acts as the solvent, pulling out water-soluble compounds and some aromatics.
The tradeoff is potency. Research comparing lavender extracts found that vinegar-based versions had very low antioxidant activity compared to alcohol tinctures or even water decoctions. You’ll get a pleasantly scented, mildly flavored product, but it won’t be as concentrated as a glycerite or oil infusion.
To make one, fill a jar one-third full with dried lavender buds and cover with vinegar. Seal with a plastic lid or place parchment paper under a metal lid, since vinegar corrodes metal. Let it steep for 2 to 4 weeks in a cool, dark place, shaking occasionally. Strain and store in a glass bottle. Vinegar extracts keep for about a year in a cool, dark cupboard.
Choosing the Right Method for Your Purpose
- Cooking and baking: Glycerite. The natural sweetness of glycerin complements lavender’s floral flavor in desserts, drinks, and syrups.
- Skincare and massage: Oil infusion. It absorbs into skin easily and can be used directly or mixed into homemade creams and balms.
- Salad dressings and marinades: Vinegar extract. It adds subtle lavender flavor to savory dishes.
- Hair rinse: Vinegar extract. The acidity helps smooth hair cuticles while leaving a light scent.
- Bath and aromatherapy: Any method works, though oil infusions and glycerites deliver the strongest fragrance.
No alcohol-free method will perfectly replicate the potency of a traditional tincture. But for home use, where you’re after lavender’s scent, flavor, and gentle soothing properties, these methods produce extracts that are practical, safe, and satisfying to make.
