Let’s Make a Coffee Bar!

If you’re like about 50% of the HSCG Staff, you need at least one cup of coffee per day to function!  Did you know that not only can you get a little energy boost from this miraculous bean water, but you can also use it in your soapmaking endeavors? It’s true! Let’s talk about taking you and your customer’s love for coffee to the next level with a coffee bar.

Coffee in the Shower 

There are a few ways you can go about using coffee in your soap; your vision for your final product will be the deciding factor that determines how you’ll use it.

Coffee Grounds 

Who doesn’t love a good exfoliant? Sugar is great, salt is well…salty, but coffee grounds are an unexpected winner too! Coffee grounds are larger than their sugary or salty comrades and provide a more aggressive exfoliant. This kind of exfoliant is great for people with rough heels or those who need a step above your typical exfoliant.

The most frequent question we receive about using coffee is, do I just use raw coffee?  The answer is both yes and no-again, it depends on your final product. If you decide to use raw grounds, beware that there is a moderate to high chance that the color of the grounds will bleed, and this will affect your final color. If you use used grounds instead, you will not have as noticeable of a bleeding color issue. Just be sure to dry the grounds before putting them in your soap to avoid clumping.

If you decide to use coffee grounds in your soap, when to add the exfoliant will depend on your process. If you are making cold or hot process soap, you can add the grounds at about .5-1.5 tsp per pound at trace-adjust this rate according to how exfoliating you’d like your finished product to be.

If you are making melt and pour soap, you’ll want to add the grounds while your soap is melted and at about 130 degrees. Make sure to stir well so that the grounds are suspended properly in the soap.

Liquid Coffee 

Many soapers don’t realize that you can actually substitute up to 100% of the water in your recipe with coffee! Using coffee for your lye water instead of water will lend a subtle scent and naturally brown coloring. It will also raise quite a stench in your workplace when mixed with your lye, so make sure you are in a well ventilated area that can be easily aired out. You’ll want to take the time to chill your coffee to at least room temperature; if you have the time, put it in the fridge overnight instead for the best results.

Although it might smell really badly when mixed, it is likely not because it is scorching-if you are using regular, unflavored coffee you will not need to worry about sugars being scorched by the lye. Keep in mind that if you do use a flavored coffee, it may contain sugars and you will need to account for this when it is time to mix your lye and coffee together.

A Few Notes About Brewing Your Soap 

As we mentioned, brewed coffee will discolor your soap – the color depends on how strong the coffee is. A weaker coffee will produce a less vibrant brown, while a stronger coffee will produce a much deeper color. If you want to lessen the impact of the color, you can choose to add titanium dioxide to your formulation, or forgo colorants altogether; the color of the coffee is desirable on it’s own.

When brewing your coffee, you may also want to brew using distilled water. Tap water can contain minerals and metals that are not favorable for soapmaking; using distilled water will help you to avoid that unpleasantness.
