I love a bit of candle making, and I really think I’m starting to become quite a dab hand at it! While I’ve dabbled with embedding things in candle wax in the past, I wanted to give it another go and so came up with this DIY coffee bean candle, with real coffee beans embedded in the base.
I love how this turned out, and although I think it would be cool to have the beans running through the whole candle, I feel this is a good compromise between aesthetics and practicality. Sometimes embedding objects can reduce the stability of your candle, but popping a couple of handfuls of beans in the base is just enough to make it look good without it falling apart.
But you don’t have to stop there, you could totally customize it to fit your own personal tastes. Flower petals, beautiful organic herbs, fruit peels, and whole spices are all excellent for embedding within a candle. I love my DIY coffee candle as it is, but you should totally use your own creativity and ingenuity to create stunning diy candles to gift, sell or just enjoy in your own home.
Supplies For Your Coffee Bean Candle DIY
- Pillar suitable wax
- Coffee fragrance oil
- Candle sealant
- Pencil, bamboo stick or a wick holder
- Pillar candle mold
- A couple of handfuls of whole coffee beans
Notes on supplies
You’ll notice that I haven’t given actual measurements of the ingredients for this coffee candle DIY. This is because the amounts you’ll need are entirely dependant on the size of your candle mold, and all molds are different. I discuss in the method how to find these measurements, and it’s relatively easy so don’t worry about it too much.
You’ll need a wax that is suitable for a free stand pillar candle for this craft. This is usually a paraffin wax, however, you can find soy blends that will support a free standing candle. If you’re unsure, contact your supplier to see whether or not the wax you intend to buy can be used in a mold as opposed to a container.
Although you can totally get away with just using a coffee fragrance for this mold, I’ve used a blend of fragrance oil for this. I find coffee fragrance oil can be quite strong, so I prefer to use vanilla as the bulk of the fragrance.
But I also added a dash of chocolate fragrance oil as well for this candle, just to give it a mocha inspired aroma. I absolutely love this combination of coffee, vanilla and chocolate fragrance oils, and I definitely recommend it. Nevertheless, you should experiment and find what works for you!
How To Make This Coffee Bean Candle
If anything seems a bit vague here, I have a much more in-depth guide to making a pillar candle which should prove helpful. While this is a little different considering the addition of the coffee beans, the principles of wicking, using a candle mold and working with wax are all the same.
Step 1: To get this DIY coffee bean candle started, it’s a good idea to first find out how much wax we’ll need for your mold. After all, all molds are different.
To do this, fill your mold with water, leaving roughly 3 inches from the top. Then, using a set of digital scales, weigh the water. I like to use grams, as it’s more accurate than your standard ounces.
While water and wax do have different densities, and so do not weigh the same, it should give us a rough idea of how much we’ll need.
Be sure to dry your candle mold thoroughly before continuing.
Step 2: Weigh out the amount of wax that we have determined necessary in step 1, and pop it in a heatproof jug. I’m using metal for mine as I find it’s easier to clean, but you can use Pyrex glass as well.
Now, fill a saucepan with a few inches of boiling water and let our jug of wax sit in it. The wax will melt slowly and evenly, preventing any burning. This is the safest, most efficient way of melting wax.
Step 3: Your wax will take a little time to melt, roughly 20 minutes. So, it’s time to wick the mold. For a detailed guide on how to choose the right size wick, see my in-depth guide to Candle Wicks and Wicking.
Using your wicking needle, thread your wick through the hole in your mold. You can then hold the wick in place by using a bit of candle sealant. This should not only keep the wick in place but also stop any wax from seeping out.
Now, turn your mold right way up and use a pencil or stick of bamboo to hold your wick steady and prevent any slack. You can buy specialist wick holders, but I find they’re a bit of a waste of money.
Step 4: By now, your wax should have completely melted. Remove from the water bath and place on a heatproof mat.
Now it’s time to add our fragrance oils! If you’re using a mix of oils, like I am, weigh them all in the same glass beaker. This will make it easier to pour into your wax. I’m using a mix of coffee, vanilla, and chocolate fragrance oils. This gives it a sweet, mocha inspired coffee aroma that I just LOVE!
When you’re happy with measurements, pour the fragrance oil into your wax. You’ll want your scent throw (the amount of fragrance oil in a candle) to be roughly 10% of the weight of your total wax, although a range of between 7-12% is fine too.
Step 5: Making sure your mold is level and sitting happily on a flat surface, pour roughly 3 quarters of your wax. Leave to harden.
Step 6: You’ll notice once your wax has hardened you’ll get what is known as a ‘sinkhole’. This is because of the wax contracts as it begins to cool, forming holes within our candle. For more information on sinkholes, see my complete guide to candle making which I wrote a little while back.
It’s important for us to fix this problem, as when we come to burn our lovely DIY coffee bean candle, a sink hole can cause it to burn poorly. We want a nice, even burn without any nasty cavities in the wax.
Simply use a stick of bamboo to push holes through the wax at a vertical angle. You’ll want roughly 4 or 5 of these around your wick. However, be careful not to disturb the wick at all. You’ll also want to avoid the sides and the bottom of the candle for a smooth finish.
Step 7: Now that we’ve made our holes, it’s time to add the coffee beans and the last of the wax. So go ahead and pop your jug of hardened wax back into the water-bath to melt once more.
While we wait for the wax to melt, take a few handfuls of the coffee and pop them into the mold. They should sit happily there while the wax continues to melt.
Once the wax has melted, pour the wax over the coffee beans. Some of the wax will sink into the holes we made earlier, and fill in any gaps in the center of our candle. But don’t pour all of the wax, leave a very small amount so we can level out the candle later.
Step 8: Let the candle harden once more. You’ll notice that the coffee beans like to float in the wax as it hardens, so we’ll need that last bit of wax we held back to get a nice, smooth surface for the candle to sit on. So go ahead and melt the last bit of wax, and add it to the candle.
Leave to harden fully overnight.
Step 9: Now we’ve left the candle overnight, we can remove it from the mold. This can be a little tricky, and you may need to gently tug on the excess wick to get it out. Be sure to remove any and all candle sealant before you attempt to remove your candle from its mold.
Step 10: You’ll notice that the coffee pokes through the wax a little. This is fine. While it doesn’t look great now, once we’ve given it a bit of a polish, the beans will look much more defined.
To polish, grab a pair of pantyhose or thin nylon tights and give it a good rub all over. Give the wax surrounding the coffee beans special attention. You’ll find any cracks and uneven wax should buff out and make the coffee beans look much more like… well, coffee beans! After all, for a coffee bean candle, you’ve kinda gotta be able to see the beans!
Step 11: Now the candle is polished, it’s time to trim the wick on both ends. Cut the wick on the base of the candle right against the surface so that your candle can sit evenly. On top, you’ll want to leave an inch or two so that you can light it easily.
So there we have it! A gorgeous DIY coffee bean candle, scented with coffee fragrance oil and a handful (or two) of coffee beans embedded in the base!
I love how my DIY coffee bean candle turned out, and I couldn’t be happier.
- While, as I said, I would love for the beans to be running through the whole candle, It wouldn’t necessarily be very practical. I think if I were to do this again, I would probably play around with the idea of making layers. So, coffee in the base, then a layer of pure candle wax, then another layer of coffee and so on. I think this could create quite an interesting look. While I know pouring and then remelting your wax over and over may become tedious, a little bit of patience can produce fantastic results!
- I also just love how this smells. I’m a real coffee lover, and can’t resist the aromas of the coffee houses in my local area. Smell is one of the strongest triggers for memory, and when I burn this candle it takes me back to the cute little cafes I would frequent during my summer vacation in Paris. I quite like playing around with fragrance blends; it sounds silly but it makes me feel like some kind of aroma scientist!
