Can You Reuse Cold Brew Grounds? 5 Surprising Ways to Get the Most Out of Your Coffee Beans


When it comes to coffee, getting the most out of your beans is essential for every coffee lover. One question that often arises is whether or not you can reuse cold brew grounds. In this blog post, we will explore the surprising ways in which you can reuse your cold brew grounds and get the most flavor and enjoyment from your coffee beans.

What are Cold Brew Grounds?

Before we dive into reusing cold brew grounds, let’s understand what they actually are. Cold brew grounds are coarsely ground coffee beans that have been steeped in room temperature or cold water for an extended period of time, usually 12-24 hours. This slow extraction method results in a smoother and less acidic coffee concentrate compared to traditional hot brewed coffee.

Can You Reuse Cold Brew Grounds?

The answer is yes, you can absolutely reuse cold brew grounds! Some people choose to do so for various reasons. Firstly, reusing them helps reduce waste and make the most out of their investment in quality beans. Secondly, while the initial extraction may have occurred during the brewing process, there is still some flavor left in the used grounds that can be extracted again through different methods.

However, it’s important to note that reusing cold brew grounds may not produce the same intensity of flavor as a fresh batch would. The second extraction will result in a milder taste profile but can still be enjoyable if used creatively.

Surprising Way #1: Cold Brew Ice Cubes

One surprising way to reuse cold brew grounds is by making cold brew ice cubes. After preparing your deliciously smooth batch of cold brew concentrate, save some leftover grounds and freeze them into ice cubes. These frozen cubes can then be added to various beverages such as iced coffees or even cocktails without diluting their flavor.

Not only do these cold brew ice cubes add a subtle coffee flavor, but they also prevent your drink from becoming watered down as regular ice would. It’s a great way to enhance the taste of your favorite beverages while also getting the most out of your coffee grounds.

Surprising Way #2: Body Scrub

Coffee has long been known for its exfoliating properties, making it an excellent ingredient for homemade body scrubs. To create a simple yet effective body scrub, mix reused cold brew grounds with coconut oil or any other carrier oil of your choice. Gently massage this mixture onto damp skin to remove dead skin cells and leave your skin feeling soft and rejuvenated.

The caffeine present in coffee also has potential benefits for the skin. It can help tighten blood vessels, reduce inflammation, and even temporarily reduce the appearance of cellulite. So not only are you reusing your coffee grounds effectively, but you’re also giving yourself a spa-like experience at home.

Surprising Way #3: Composting

Composting is another fantastic way to reuse cold brew grounds while benefiting the environment. Coffee grounds are rich in nitrogen and other essential nutrients that can enhance compost quality and provide nourishment to plants.

To incorporate coffee grounds into your compost pile or bin effectively, make sure to mix them with carbon-rich materials like dried leaves or shredded paper to balance the nitrogen content. This will help speed up decomposition and create nutrient-rich soil for gardening purposes. Remember that moderation is key; adding too many coffee grounds can alter the pH balance of your compost.

Surprising Way #4: Odor Neutralizer

If you’re struggling with unpleasant odors in certain areas of your home, reusing cold brew grounds can come to the rescue as a natural odor neutralizer. Simply place used cold brew grounds in small bowls or open containers and position them near areas with strong smells such as refrigerators, garbage cans, or even shoe racks.

The coffee grounds will help absorb and neutralize odors, keeping your home smelling fresh and clean. This is a simple yet effective way to repurpose your grounds while maintaining a pleasant living environment.

Surprising Way #5: Cooking/Baking Ingredient

Last but not least, let’s explore how reused cold brew grounds can be used as an ingredient in cooking and baking. The mild coffee flavor present in the used grounds can add depth and richness to various dishes, particularly those with chocolate undertones.

Experiment with adding reused cold brew grounds to chocolate-infused recipes like brownies, cakes, or even savory dishes like chili or barbecue sauce. The possibilities are endless, so don’t be afraid to get creative in the kitchen!


In conclusion, reusing cold brew grounds can be a fun and creative way to get the most out of your coffee beans. From making cold brew ice cubes to creating body scrubs or using them as an odor neutralizer, there are numerous surprising ways to repurpose your grounds instead of simply discarding them.

So the next time you enjoy a refreshing glass of cold brew coffee, think twice before throwing away those leftover grounds. Give one of these surprising methods a try and experience the versatility and enjoyment that comes from reusing your coffee beans creatively.
