From plant fertiliser to hair conditioner: 10 ways to use leftover coffee06/05/2020
Are you holding a cup of coffee in your hand?
Before you drink it, we’d like to give you some alternative ways to use this caffeinated beverage – as it turns out, coffee has many more uses beyond keeping us alert in the office.
We asked experts at Coffee Direct to share their tips and tricks with us.
From pouring leftovers in your hair to getting rid of bad breath and decorating your home, here are 10 ways to use the nation’s favourite brown liquid.
Fancy giving your wooden furniture a quick makeover?
Coffee Direct said: ‘As well as being a natural, non-flammable alternative to store-bought wood stains, staining with coffee will give the wood a beautiful, caramel tone.
‘Coffee reacts with the tannins in wood to help reduce blotchiness and give the wood a uniform colour.
‘Simply wait for your brewed coffee to cool, sand down your surface and use a rag to evenly coat the wood. The darker you want the stain, the more coffee you use!’
Are your plant babies looking a bit dull? Give them a hit of caffeine.
Coffee Direct said: ‘Diluted coffee can be extremely beneficial to plant health.
‘As brewed, black coffee contains potassium and magnesium, it acts as a nutrient to plants allowing for stronger stems and a vibrant, green growth.
‘To use this as fertiliser, dilute your brewed black coffee so that it is a 1: 4 ratio (coffee: water) and feed your plants once a week with this solution.
‘Make sure there is no sweetener that could attract pests, and that your coffee is not too strong when “watering” your plants, as it could be too acidic for the soil.’
Prepare to have your mind blown – you can use your old coffee to make your new coffee even tastier.
Coffee Direct said: ‘Why not use your leftover coffee to upgrade your next coffee? Use coffee syrup to drizzle over your next coffee frappé!
‘Simply boil brewed, black coffee with an equal amount of sugar until it becomes reduced and thick in texture.
‘This syrup can last in the fridge for two weeks, so you can also use this to upgrade desserts such as ice-cream and pancakes too.’
Has your hair lost its shine? Forget expensive beauty products, and invest in great coffee.
Just make sure the coffee is cold before you pour it over your head.
Coffee Direct said: ‘Caffeine in coffee is great for hair. Not only does it encourage the hair roots to grow, but it stimulates the roots and improves scalp health too.
‘After shampooing your hair, simply pour cold coffee over your head and scalp.
‘So that the coffee doesn’t stain your bathtub, make sure you do this over a bucket. Put your hair in a shower cap and leave the coffee in for half an hour before rinsing off with warm water.
‘Do this once a week, and you will notice an improvement in the thickness and texture of your hair.’
For this one you need beans, not brewed coffee.
Coffee Direct said: ‘Old or leftover coffee beans make rustic and beautiful vase fillers for the home.
‘Gather light and dark variations of coffee beans in clear glass vases, checking if they have a nice scent when combined.
‘Arrange your flowers in the vases, and you will find that the coffee beans hold the stem upright. If you do not have enough coffee beans to fill the vase, you could try layering them with other small stones, dried petals or glass beads for visual interest.’
Coffee isn’t just for drinking, you can use it in your cooking, too.
Coffee Direct said: ‘Few people know that with the right spices, brewed coffee can provide a pleasant and delicate taste to steak, pork or fish.
‘Sauté one medium onion and four minced garlic gloves and add it to a bowl.
‘To this, add 240ml strong coffee, 60ml balsamic vinegar, 55g of brown sugar, 60ml Dijon mustard, three tbsp olive oil, pepper and salt to taste.
‘Cover your fish or meat in the marinade and leave it in the fridge for at least an hour before cooking.’
Natural pest repellent
Have an infestation problem? OK, you’re probably best off calling the professionals, but while you wait for them to arrive, you could try this trick for yourself.
Coffee Direct said: ‘The smell of coffee is great for repelling common household pests such as mosquitos, ants, slugs, cockroaches and more.
‘All you have to do is set bowls of coffee grounds out, and this should keep the pests away. We recommend freshly ground coffee for this, as the aromas will linger longer.
‘You can also put some of these coffee grounds in your pet shampoo to help naturally prevent fleas.’
DIY air freshener
If you don’t like the smell of coffee, this isn’t one for you.
Coffee Direct said: ‘Coffee is fantastic for neutralising other odours, which is why it makes a great DIY air freshener.
‘Simply place some coffee beans in a mesh bag and stash it away under the passenger seat.
‘The coffee’s natural scent will be released slowly, and the beans will absorb any unpleasant, overpowering odours.’
Tired of watered-down ice coffees? This is the hack we all need ahead of the summer heatwave.
Coffee Direct said; ‘If you don’t want to water down your iced coffee, pour your leftover brew into an ice cube tray.
‘Freeze the cubes, and then pop them out whenever you need to make your iced drink extra cold and flavourful.
‘Depending on your coffee flavour, you can also add or adjust the ingredients in your ice cubes to upgrade your drink.
‘For example, you can whisk together sweetened condensed milk and leftover coffee for a Vietnamese coffee variation, or add some caramel to your leftover coffee before freezing for a Macchiato variation.’
Eliminate bad breath
We were surprised at this suggestion, since coffee can actually give people bad breath – but there’s a nifty explanation for this.
Coffee Direct said: ‘While those old coffee beans may not be good enough to make coffee with, they may still be edible.
‘Some may attribute their bad breath to drinking coffee, but it is actually the caffeine to blame – not the bean.
‘Believe it or not, sucking on a coffee bean can help eliminate bad breath.
‘As well as being much cheaper than a breath mint, it also tastes great and neutralises even the strongest scents such as garlic.’
