Reusing Coffee Grounds: Can You Use Coffee Grounds Twice?
Have you ever wondered if you could save some pennies by not throwing your used coffee grounds away, but by reusing them instead?
The short answer is, you shouldn’t reuse already brewed coffee for making yourself a new cup.
However, there are many other ways you can recycle coffee grounds.
Keep reading for some inspiration!
Recycled Coffee Grounds Will Not Have The Right Flavour
Coffee extraction is a science aimed at getting the maximum flavour from your beans. Your goal is to avoid under-extraction, which will produce a sour flavour, as well as over-extraction, which will result in a bitter cup.
Coffee beans contain over a thousand chemical compounds from which they get their characteristic flavour. Compounds like Furaneol give a caramel taste, while Acetaldehyde is a source of pungent fruitiness.
As coffee brews, these compounds are steeped into the water, turning it into the beverage you know and love. Once you hit that sweet spot of perfect extraction, you’re basically transporting the full flavour profile of the beans into your cup. Logically, this means that a second steep would produce unsatisfactory results.
Therefore, it’s not a good idea to brew coffee grounds twice. If you’re feeling thrifty, there are much better ways to reuse your grounds!
4 Ways To Recycle Coffee Grounds
Before you throw them grounds into the trash, remember that they can still provide you with benefits. Coffee keeps on giving! Try one of the following:
1. Cultivate Your Garden
If you have a garden, there are lots of things you can do with used coffee grounds.
Composting coffee increases the level of nitrogen in the compost, helping to maintain the ideal carbon-nitrogen ratio required.
In one experiment, a successful urban compost was created using nothing but coffee grounds and old newspapers.
Coffee grounds can also be used as fertiliser, because they add organic material to the soil. This attracts earthworms and helps useful micro-organisms thrive.

2. Caffeinated Beauty Boost
You can easily incorporate used coffee grounds into your beauty routine as well.
Coffee grounds can be made into an exfoliating scrub for both your face and body. You can also try making this luxurious coffee and cocoa face mask, or just get creative and try mixing some of your favourite ingredients for a DIY treatment.
You can also treat your hair with coffee. If you’re brunette, add some used coffee grounds to your shampoo before use. This will enhance the color of your hair and make it shinier. For blondes, this isn’t recommended, as it will slightly darken your hair colour.
The caffeine in the grounds can also boost hair growth - a cheaper alternative to biotin supplements.

3. Polish Your Possessions And Banish Fridge Smells
Coffee grounds can also come in handy when you’re scrubbing surfaces and polishing shoes. You can use them to treat unsightly scratches on your furniture.
Simply apply some used coffee with a cotton Q-tip to cover the blemishes and let it sit for 10 minutes before removing.
You can also use coffee grounds to stain wood naturally. Mix used coffee grounds with boiling water, strain and pour into a container - you don’t want to drink this! Then simply use a brush to paint the desired surface with the coffee staining mixture. Repeat until you get the colour you want.
Coffee has natural deodorising properties, so you can also use it to get rid of food smells in your fridge. Just leave some used grounds in an open-top container at the back of your fridge for a week or two. They will absorb food smells like magic.
#4 Make Coffee Candles And Soaps
For an impressive DIY gift option, or just to treat yourself, you can use coffee grounds to make candles.
Just add used coffee grounds to the soap mixture, melt everything over heat and ladle into muffin tins.
Let it sit and cool for a few hours, and voilà, you’ve got the perfect gift option for a coffee lover (or yourself).
