By Ann Hills / 5 years ago

Are you a coffee lover? Have you ever felt that it is such a shame to throw away the coffee grounds after using them once because they still have a strong odor?

Have you ever wondered what will happen if you reuse coffee grounds for your next pot of coffee? A lot of people have these type of questions.

Can you reuse coffee grounds? The answer is yes, you can reuse coffee grounds to make more coffee.

The second time can still be drinkable. However, it will have a reduced amount of caffeine and other flavor compounds which can influence the taste of the coffee. That is why it is recommended to use the coffee grounds once.

If there’s only one fact about brewing coffee, it’s this: you will always end up with used coffee grounds. A regular coffee habit can produce a lot of coffee waste by the end of the week.

Well, you might as well do something about them. You know, aside from a carafe’s worth of coffee.

Effects of Reusing Coffee Grounds

Coffee has the right amount of extraction which is essential for a delicious cup. That is why if you reuse coffee grounds, it will dilute the coffee which leads to the coffee being bitter or bland. Brewing an ideal cup of coffee is a work of art.

Coffee to water ratio, water temperature, steeping time and brewing methods are all necessary. If you determined to drink better coffee, never reuse the coffee grounds. Do not feel it is a waste to use the coffee grounds once.

First brew: sweet, ripe, transparent, complex and acidity

Second brew: Bitter, lacks sweetness, salty and bland

The second brew coffee will give you such an awful drinking experience, then why don’t you let it go?

Here are some tips for using coffee grounds:

If you wish to save some coffee grounds, then try to brew a bigger batch of coffee all in one go. I realized that I use fewer coffee grounds for an 8-cup thermal carafe than for eight different cups.

Do not throw away the used coffee grounds. It has a lot of the various applications. It can suck up bad smells, fertilize your garden, grow mushrooms and so many more uses.

A new study by the ACS’ Journal of Agricultural and Food Chemistry which shows that used coffee grounds are an excellent source of healthy antioxidant substances.

To plant food, insect repellant and other uses for spent coffee grounds, Maria-Paz de Pena, and other researchers are adding an application that could make the used coffee grounds an excellent resource for producing food supplements.

They explain that individuals around the globe drink millions of cups of coffee daily, producing about 20 million tons of used coffee grounds every year. Even though some used coffee grounds are used as fertilizer, most end up in rubbish landfills.

The coffee itself is a good source of healthy antioxidants. De Peña's group wondered about a number of antioxidants that remained in spent coffee grounds from various coffee-making methods.

They discovered that filter, plunger and espresso-type coffeemakers have more antioxidants in coffee grounds, while mocha coffeemakers have the least.

Because filter and espresso coffeemakers are more popular in homes and commercial kitchens, the researchers claim that most grounds are likely to be good sources of antioxidants and other useful substances. They also state that after these compounds are extracted, the coffee grounds can still be used for fertilizer.

Genius Ways to Reuse Coffee Grounds

After doing some research on reusing coffee grounds, I have found some genius ways on how to reuse coffee grounds around the house:

01. Compost

The good thing about paper filters and coffee grounds are that both are compostable. Used coffee grounds are abundant in nitrogen, which makes them ideal for composting. (Worms love coffee almost as much as you do!)

In a compost pile, the target for a ratio of one part leaves to one part fresh grass clippings to one part coffee grounds.

Don’t forget that freshly brewed coffee grounds won't have the same effect on your garden; you should make sure that they have broken down and composted before you toss them on your plants.

02. Clean plates

Since coffee grounds have a coarse texture of coffee grounds, they are effective as an abrasive, which means you can utilize them to clean hard-to-wash plates.

Just put some coffee grounds into a cleaning rag and twist the ends with a rubber band to secure them in place. Then you have a perfect DIY coffee sponge to wash.

03. Exfoliate

Just like coffee grounds are an excellent abrasive for washing your plates and kitchenware, they can also be a good exfoliant for your skin.

Combine with equal parts olive oil and rub into your skin. The coffee grounds exfoliate, while the olive oil acts as a moisturizer.


04. Fix furniture scratches

Do you have a dining table that requires some fixing? Combine a pot's worth of used coffee grounds with 1/4 cup warm water and 1/4 cup vinegar, shake and set aside for about one hour.

Next, use a rag to rub the mixture into scratches to make your furniture looking brand new.

Same as baking soda, coffee grounds can help remove bad odors. Put a bowl of grounds in your fridge to absorb all the foul odors.
