How To Make Old Coffee Taste Good

Vietnam, one of the greatest and most under-rated hip and trendy coffee cultures in the world, has a lovely trick to revitalise old coffee beans.

Simply add a pinch of salt to your cup of coffee to take away that overtly bitter taste. Surprisingly, salt counteracts the bitterness of coffee. The Vietnamese have a special coffee, salt coffee that is rather lovely and great tasting.

The history behind salt and Vietnamese coffee was to prolong the life of the coffee beans. Today, it is used with fresh beans and is a speciality coffee drink.

How To Refresh Old Coffee Beans

Following on from the salt trick, you can refresh old coffee beans by using them to make flavored coffee beans.

Simply use some fresh spices like cinnamon, vanilla, cacao or coconut to freshen up and add flavor to and refresh old coffee beans.

Simply chop them up and add them to your coffee cannister, shake them well, so the spice is mixed well and evenly and let them sit there for 24 hours to 36 hours to absorb the scent and flavor of the spice.

Once your desired level of taste has been achieved, remove the spice to prevent it from overcoming the coffee taste and being too dominant a flavor.

#1 Neutralize Odors. 

Coffee grounds are high in nitrogen which, when combined with carbon, which is also found in coffee grounds, helps to remove bad odors due to its ability to get rid of sulphur gas from the air.

It is absolutely true that coffee grounds absorb and eliminate bad odors. It is this ability of coffee grounds and coffee beans to absorb scents is what makes them able to absorb the scents and flavors from foods and spices that are near them and make flavored beans.

Using a bowl of coffee grounds in your freezer, fridge, pantry or garage will help to neutralise bad smells from anything, including spoilt foods.

I keep a bowl of coffee grounds on my counter top to absorb scents like garlic, onions and other organic materials.

#2 Scrub Pots And Pans. 

Another great use in the kitchen is to make and use the rough and coarse texture of your old coffee beans and grounds to clean caked on and baked in food and grime on your dirty pots and pans.

Simply sprinkle them on and scrub as you normally would and rinse well afterwards.

#4 Exfoliate Skin.  

I touched on and mentioned this earlier, and moving from the kitchen to the bathroom, you can use coarse rough coffee particles that are in coffee grounds and use them as an alternative to expensive skin scrubs to remove dead skin tissue and cells to improve your skin appearance.

Just take some old coffee beans, grind them, and mix your grounds with coconut oil to make a skin scrub. Simply use the scrub as you would any other scrub and apply it to your hands, face and body.

Thanks to the caffeine in coffee grounds, you can enjoy its protective antioxidant properties and improved blood flow.

You can also get arty and use it as coloring for Easter eggs and even to deepen the color of your hair. The best part is it is 100% natural and chemical free and non-toxic.

#6 Reduce Cellulite!

Just as you can make an exfoliant skin scrub, you can improve the appearance of skin imperfections by making an anti-cellulite scrub with your old coffee beans and grounds.

The caffeine content of your old coffee grounds when you apply it to your skin may have the effect of increasing blood flow and help break down the fat deposits underneath your skin.

#7 Clean Your BBQ Or Fireplace.

An easy way of cleaning the ashes from your barbecue or home fireplace is to use your old coffee grounds to weigh them down and reduce the dust formation. They can also serve as a fire safety tool for your outdoor charcoal barbecue and you can use them to safely put out the fire.

#8 Tenderize Meat

This can make a great tasting manly steak grilled on your barbecue. Coffee has natural enzymes that can help to break down proteins and result in a softer texture.

Also,

due to coffee being acidic, you can use your old grounds to enhance the flavor of your meat. Simply add your coffee grounds to your dry rub recipe and apply it to your meat approximately 2 hours before you cook it. Your grounds will get cooked into your meat with the result being a delicious, dark, crust.

You also use your grounds to brew a strong marinade for your meat and marinate for 24 hours before cooking.

#9 Cultivate Mushrooms.

Keeping with the culinary topic. You can use and take advantage of your old coffee beans and grounds and their high levels of nitrogen and use them to make a substrate for mushrooms to grow in.

Despite the difficulty of growing mushrooms, coffee grounds are perfect as a substrate as they contain a number of nutrients that aid in the growing of mushrooms.

Note: It is best you use used coffee grounds as these have been sterilised thanks to the brewing process.

#10 Furniture Repair. 

Scratched wooden furniture can easily be fixed by making a thick paste from old coffee beans and grounds.

Simply make a paste with water and rub and dab it on your scratched wooden furniture. Wait for 6 to 10 minutes and then wipe gently with an old cotton rag. Repeat as necessary.

Keep dabbing and rubbing on the past until your scratched furniture has the damage concealed. Wait a few hours between applications to ensure it has dried, then re-apply as needed.

#11 Flea Removal From Your Pet.

Coffee is a great natural insecticide and those pesky fleas don’t like it! Be very careful, coffee should never be consumed by your pooch as it is toxic for them.

The benefit of using coffee for flea removal is it is a natural and chemical free solution.

Simply rub old coffee grounds in abundance through your dog’s fur after you give him or her a good shampooing. Rinse well and allow your dog to dry naturally.

You are best to clean your dog outside as the fleas will want to go somewhere! That somewhere is best not inside your home!

#12 Use As An Insect Repellant!

This is my number one secret as to why and how I keep my home coffee shop free from insects, mosquitos and all kinds of bugs.

There is no need to go over the top. Just have plenty of plants with coffee grounds abundantly sprinkled on the soil and placed smartly around the room. I have grounds in ashtrays as a fire prevention hazard.

The double bonus is the grounds also absorb bad scents.

Also, coffee has the ability to absorb heavy metals from the soil.

Old Coffee Beans And Cold Brew Coffee

A lot of people tend to use old coffee beans to make cold brew as the extraction time, the brewing time is significantly longer. The belief is the fact the coffee beans are old, the effect and impact on the flavor is reduced.

This is not true at all.

It is most certainly not a way to make one of the best and most refreshing coffee drinks.

I don’t advise at all the use of old coffee beans to make cold brew coffee. If anything, use beans that are as fresh as possible and double brew your cold brew with hot water and then cold water for a focused and great tasting cold brew coffee.

Coffee is love, it's more than love — it's a passion of mine. I've had the luck to have travelled and enjoyed the most exotic of coffee's and unique flavors, brewing methods and techniques of making the perfect coffee from Thai hill tribe coffee to Indonesian volcanic coffee, Malaysian coffee that comes in a tea bag and the array of flavors in Vietnam, from Vanilla to Orange to Coconut to Avocado to even salt coffee and the famous egg coffee. The best part of my coffee adventures is getting to mix with the locals over a nice brew and learning how they make it! I'm cited and referenced on Google Scholar for the topic of coffee.
