How To Make Coffee Infused Oil + 6 Satisfying Ways To Use It
Coffee has one of the most recognizable aromas in the world – warm, roasted, deeply comforting. Coffee-infused oil captures that scent in a form you can use as a base ingredient across a whole range of DIY bath and body projects, from bath salts and sugar scrubs to whipped body butter and melt-and-pour soap.
The process of making coffee-infused oil is unhurried and immensely satisfying. You steep ground coffee in a carrier oil, let time and warmth do the work, then strain it into a clean bottle.
What you end up with is a richly scented oil that carries that familiar coffee aroma into anything you blend it into without the grounds, the mess, and the need for any specialist equipment.
There are two methods you can use to make coffee oil. One is a slow, cold infusion that develops over a couple of weeks. The second is faster hot infusion using a double boiler.
Both produce a beautiful, rich, aromatic coffee-infused oil. The difference is mainly one of patience.

Choosing Your Ingredients to Make Coffee Oil
The Carrier Oil
The carrier oil is the base the coffee aroma infuses into, so it’s worth taking the time to choose one that meets your needs.
You also want to make sure to use a mild-scented carrier oil that won’t compete with the scent you’re after.
Neutral oils such as grapeseed, sweet almond, and fractionated coconut oil have mild natural aromas that let the coffee scent come through cleanly. These are the most versatile choice if you plan to use the finished oil across multiple recipes.
Jojoba oil, which is technically a liquid wax rather than an oil, has a particularly long shelf life, which makes it a good choice if you’re planning to make a larger batch or want the finished oil to keep well.
Avocado oil has a richer, slightly heavier character and a longer shelf life than many other oils. The natural aroma is mild enough not to overpower the coffee.
Olive oil, specifically extra virgin, has its own pronounced flavor and scent that can compete with the coffee infusion. If you want to use olive oil, choose a lighter grade so the aromas don’t compete.
The Coffee
Freshly ground beans deliver a noticeably stronger, richer result than pre-ground beans. If you have a grinder, it’s worth grinding the coffee beans just before using.
- Grind: A medium grind is the sweet spot. Straining can become challenging when you use fine grounds as the grounds find their way through the mesh, resulting in a gritty infusion. Too coarse and less surface area means less aroma transferred.
- Roast: Lighter roasts bring brighter, slightly floral notes. Darker roasts give a bolder, more intensely roasted character. Both work equally well. It comes down to what scent profile appeals to you and what you’ll be using the oil for.
- Organic: Worth considering, particularly if the finished oil is going into leave-on products like body butter. Organic beans and organic carrier oil keep the ingredient list as clean as possible.
How To Make Coffee-Infused Oil: Cold & Hot Infusion Methods
Two methods, the same result. Choose based on how much time you have.
Cold Infusion – The Slow Method

The cold infusion is the more hands-off of the two methods.
- Add the ground coffee to a clean glass jar.
- Pour the carrier oil over the grounds slowly. It will take a few minutes to work its way down.
- Add the oil till the grounds are fully submerged. Grounds exposed to air above the oil line can go moldy.
- Seal the jar tightly, label it with the date and contents, and store it in a cool, dark place.
- Leave to steep for at least two weeks. Shake or stir gently every few days to encourage extraction.
- Check the scent after two weeks. If you’d like a stronger aroma, leave for another week or two.
When you’re satisfied with the strength of the aroma, strain the infused oil through a fine-mesh strainer lined with cheesecloth. Pour the infusion into your storage bottle.
Many people find cold-infused oils have a richer, more complex scent than hot-infused ones, simply because of the longer extraction time. The aroma has more time to develop slowly and deeply.
Tip: Squeeze the cheesecloth gently at the end to extract every last drop of oil from the grounds. It makes a noticeable difference to the final yield.
Hot Infusion – The Faster Method
The double-boiler method uses gentle heat to speed up the infusion process from weeks to hours. The key word is gentle when using this method. You want a low, steady warmth, not anything approaching a simmer in the jar itself.
- Add the ground coffee and carrier oil to a heat-resistant glass jar.
- Set up a double boiler: fill a saucepan with a few inches of water and place the jar inside, making sure it doesn’t touch the bottom of the pan.
- Heat the water on medium-low until it reaches a gentle simmer, then reduce to low. The oil in the jar should feel warm but never hot enough to bubble or smoke.
- Infuse for 4 to 7 hours, stirring occasionally. Check the scent at the 4-hour mark — if it’s already where you want it, you can stop there.
- Remove from heat and allow the oil to cool completely before straining.
- Strain through cheesecloth into a clean bowl, then pour into your storage bottle.
Tip: Keep the heat low throughout. If the oil begins to smoke at any point, remove the jar immediately. Overheating damages the carrier oil and dulls the coffee scent rather than intensifying it.
Should You Use the Hold or Cold Infusion Method?
The cold infusion is the better choice if you have two weeks to spare and want the deepest possible coffee aroma. It’s also easier as it’s completely hands-off after the first few minutes.
If you need the oil sooner, or want to make a batch in an afternoon, the hot infusion delivers a very good result in a fraction of the time. Keep an eye on the heat, and it’s a reliable method.
Tips for Straining the Coffee Infusion
Cheesecloth is the most effective straining material. It lets the oil pass through cleanly while capturing even fine grounds, and it’s easy to squeeze for maximum yield. Line a fine-mesh sieve with several layers for the best result.
A coffee filter works in a pinch, but has two drawbacks: it allows finer particles through, which can leave the oil slightly cloudy, and it absorbs more oil than cheesecloth, so you lose a little of your finished product in the process.
Once strained, pour into a clean, dry dark glass bottle or jar and seal immediately.
How to Store Homemade Coffee-Infused Oil
Store in a cool, dark place away from direct sunlight and heat – a cupboard shelf rather than a windowsill. The dark glass helps protect the oil from light degradation.
When stored properly, coffee-infused oil keeps for up to three months, though this varies depending on the carrier oil you used. Jojoba lasts longest; olive oil is the most prone to turning rancid.
A rancid or off smell, cloudiness that wasn’t there before, or any visible colour change are all signs that the coffee oil has gone bad. When in doubt, throw the oil out and make a fresh batch. Do not use it. The ingredients are inexpensive, and the process is quick enough to repeat.
Tip: Label the bottle with the date made and the carrier oil used. It takes a minute to do this and saves you guessing later.
Coffee Infused Oil Is Not Coffee Essential Oil
A quick distinction worth making, because the two are often confused.
Essential oils are highly concentrated aromatic compounds extracted from plant material through steam distillation or cold pressing. Coffee beans don’t contain sufficient volatile compounds for this process, which is why there’s no such thing as a true coffee essential oil.
Coffee-infused oil is something quite different. This is basically a carrier oil that has absorbed the aroma and soluble compounds from steeped coffee grounds. It’s a gentler, slower process, and the result is an oil that smells richly of coffee rather than a concentrated aromatic extract.
The two are not interchangeable in recipes.
Ways To Use Coffee-Infused Oil in DIY Recipes
Once you have a bottle of coffee-infused oil, it works as a direct carrier oil substitute in almost any bath and body recipe, bringing the coffee scent along with it. Here are six ways to put it to use.
Coffee Bath Salts
Coffee-infused oil works as the carrier in this layered coffee bath salts recipe, distributing evenly through the salts and carrying the roasted aroma into every layer.
Combined with ground coffee and goat’s milk powder in alternating layers, the finished jar looks as good on a shelf as it does dissolved in a warm bath.
Coffee Sugar Scrub
Swap the carrier oil in any sugar scrub recipe for coffee-infused oil, and the warm, roasted scent carries through the whole batch.
Brown sugar pairs particularly well. The tones complement each other visually, and the scent combination is naturally cosy. A lip scrub version using fine white sugar is a nice variation for a smaller gift jar.

Whipped Body Butter
A few tablespoons of coffee-infused oil stirred into a whipped body butter recipe adds a warm, rich scent without changing the texture.
It works particularly well in a base that already has a golden or amber tone. Shea butter, mango butter, or cocoa butter all pair naturally with the coffee character. Keep the framing around scent and the sensory experience of the whipped texture.
Melt and Pour Soap
Substitute coffee-infused oil for the carrier oil called for in any melt-and-pour soap base. The scent carries well through the soap-making process, and the finished bars have a warm, inviting aroma.
For a visual touch that matches the scent, press a few whole coffee beans into the surface before the soap sets. They sit beautifully against a cream or honey-coloured base, adding a lovely decorative element.
Bath Bombs
Add a tablespoon of coffee-infused oil to your bath bomb recipe in place of the standard carrier oil. The scent disperses well into the bath water as the bomb fizzes, and the oil leaves a light conditioning film.
The dark, roasted note pairs nicely with warm spice essential oils. Cinnamon bark or cardamom works particularly well if you want to layer the scent further.
See the rose petal bath bomb recipe for the base method — swap in the coffee-infused oil and your chosen scent additions.
Coffee Lip Scrub
A simple two-ingredient project: fine white sugar and coffee-infused oil, combined until you have a loose, scoopable scrub.
The oil provides slip, and the sugar does the exfoliating work. The coffee scent makes the lip scrub feel a bit more considered than a plain sugar scrub.
Use cosmetic-grade fine sugar rather than granulated to keep the texture gentle on the lips. A small cork-lid jar makes it a natural companion gift alongside the coffee bath salts.
Making your own coffee-infused oil is one of the more satisfying carrier oil projects — the ingredients are simple, the process is straightforward, and the result is something you’ll actually reach for.
Whether you use it as the base of a single recipe or work through the whole collection, that warm roasted scent has a way of making any DIY feel like a small occasion.
Frequently Asked Questions
How long does it take to make coffee-infused oil?
The cold infusion method requires a few minutes of active time spent but is ready to use only after two to four weeks, depending on how the desired scent strength. The hot infusion method requires a longer time investment of about four to seven hours using a double boiler on low heat, but is ready to use immediately.
What’s the best carrier oil to infuse coffee?
A neutral oil such as grapeseed, sweet almond, or fractionated coconut lets the coffee scent come through most cleanly. Jojoba is a good choice if shelf life is a priority, as it lasts longer than most true oils.
Can I use pre-ground coffee to make an infusion?
Yes, though freshly ground beans give a noticeably richer result. If using pre-ground, choose a medium grind and check it’s reasonably fresh. An infusion made with pre-ground coffee will have a weaker scent.
How do I know when the infusion is strong enough?
Smell it. Start checking at the two-week mark for cold infusion, or at four hours for the hot method. If the scent isn’t where you want it, give it more time and check again. There’s no correct scent strength. It’s based entirely on your preference.
Can I use the spent grounds after straining?
Yes, and it’s so worth it. Dried spent grounds can go straight into a coffee bath salts recipe or be used as a simple exfoliant in a sugar scrub. Nothing wasted.
Is coffee-infused oil the same as coffee essential oil?
No. There is no such thing as a true coffee essential oil. Coffee beans don’t contain the volatile compounds needed for steam distillation. Coffee-infused oil is a carrier oil that has absorbed the aroma and character of steeped grounds. The two are not interchangeable.
