Mason Jars for Cold Brew Coffee

Cold brew coffee is the ideal summer beverage. It features less acidity than its traditional counterpart and can easily be made at home.

All you need for this process is a mason jar filled with some ground coffee and some water, then mix the grounds together before leaving it to steep for 12 to 24 hours.

Easy to make

Mason jars provide an easy, cost-effective method of cold brewing coffee, all you need are some common kitchen ingredients and time. Plus they’re recyclable – so your contribution helps the environment!

As with any cold brew process, grinding your coffee coarsely will allow for full flavor extraction without bitterness.

Once ground, fill a Mason jar halfway with water and stir well so the grounds become fully saturated before placing in the fridge and leaving to steep for 12 to 24 hours (the longer this period lasts, the stronger your cold brew will become).

Once the coffee has steeped for several hours in its container, remove it from the fridge and use a mesh filter to filter the coffee into another jar for later consumption.

You can keep your cold brew stored in the fridge for up to two weeks; or enjoy drinking it hot or adding milk and ice as an irresistibly refreshing treat!

Cold brew coffee is so straightforward to create, making it perfect for both you and the environment! Plus, you can customize it according to your personal taste with various flavored syrups or sweeteners for the ideal brew for you.

Great for on-the-go

Making cold brew at home is an economical and eco-friendly way to cut expenses. All it requires are two ingredients that may already be found in your kitchen: mason jar and coffee grounds.

Furthermore, this method is both more affordable and eco-friendly than purchasing packaged cold brew from store shelves.

For cold brew, simply combine 5-6 tablespoons of coarsely ground coffee with water from a filter-equipped tap. Let it steep for 12-18 hours and enjoy!

After steeping, your coffee will become concentrated and can be stored for several days in the fridge before drinking; however, to preserve flavor and texture it should be consumed within one week of being made.

To guarantee freshness of cold brew, transfer it into an airtight bottle such as wine bottles with airtight lids that pump out air.

Concentrates can be consumed directly, though for optimal results it is often recommended to dilute them with equal parts of water or milk to lessen its intensity for certain individuals and save some of it for later consumption.

Saves you money

Mason jars make cold brew easier for anyone who likes experimenting with various coffee beans and roasts without incurring the high cost associated with traditional coffee makers.

Mason jars come in various sizes from pint to quart so you can create cold brew that fits your specific needs.

Cold brew requires coarsely ground coffee and water – either tap or filtered – in the right proportions, depending on the strength you desire for your coffee. Experimentation will likely be required until finding an ideal ratio: typically 1 part coffee:5 parts water.

Once your coffee has steeped, the next step should be straining it using either a fine mesh sieve or cheesecloth.

When doing this, make sure all of the grounds have been removed so your final coffee product can be tailored to meet your desired strength and flavor profile.

Homemade cold brew requires mixing coffee grinds with water in a container before leaving it to steep for several hours, often leading to messy results and lengthy process times. But with County Line Kitchen Mason Jar Cold Brew Coffee Maker it can become much simpler and faster!

Environmentally friendly

Mason jars make ideal containers for cold brew coffee thanks to their capacity and coffee-to-water ratio. You can buy mason jars with either two-part lids or one-piece lids; both provide tight seals against spoilage and air leaks.

However, your selection depends on its intended use; two-part lids tend to work best for canning while one-piece lids may be better suited for non-canning uses like dry storage or refrigeration.

To create cold brew, first grind your coffee coarsely before mixing with water in a jar. Cover and place in the refrigerator to steep for 12-24 hours for optimal flavor extraction; more concentrated flavors will come from longer steeping periods but beware over-steeping, which could result in bitterness.

Once your coffee is complete, strain it to remove any grounds. A fine mesh sieve, cheese cloth or specially designed cold brew filter are all effective ways of doing this; I prefer one with an easy pouring lip/spout for mess-free pouring.

Finally, transfer the concentrate into your glass or mug of choice and enjoy! If the cold brew is too strong for you to drink comfortably then simply dilute with either water or milk at a 1:1 ratio to lessen its potency.


In conclusion, mason jars have proven to be a versatile and practical choice for crafting delicious cold brew coffee. Their simplicity, durability, and airtight seal make them ideal vessels for steeping and storing your cold brew creation.

Whether you’re a coffee enthusiast looking to experiment with different flavors or someone seeking a convenient and cost-effective way to enjoy refreshing cold brew at home, mason jars offer a stylish and functional solution. 

With the convenience of preparing and serving your cold brew directly in the same jar, these timeless containers add a touch of charm to your coffee ritual. So, embrace the trend of using mason jars for cold brew coffee, and elevate your summertime caffeine fix with a smooth and satisfying sip every time.
