A cold brew infuser is a tool for making cold brew coffee. It typically consists of a container, often made of glass or plastic, with a fine mesh filter or infuser basket inside. However, some infusers come with just the mesh basket. Coffee grounds are steeped in water between 8 and 24 hours to create cold brew concentrate. You can dilute this concentrate by adding more water or milk. 

Our team compiled a list of the best cold brew infusers, evaluating them based on volume, size, maintenance level, and durability. The County Line Kitchen Cold Brew Infuser takes our top spot because of its large size, container/jar versatility, and high-quality BPA-free materials.

The Best Cold Brew Infuser Buying Guide

Iced coffee and cold brew, both chilled and satisfying, have earned a top spot in many people's morning routines. While ice coffee can be delicious, cold brew has reigned supreme in recent years due to the depth of flavor the brewing draws out. Instead of brewing coffee and throwing ice cubes in it (that will inevitably water down the richness), cold brew steeps the coffee in cold water for 12-24 hours, enhancing the flavor, reducing acidity, and providing a richer taste. To maximize the flavor of a cold brew, you'll need a cold brew infuser. With a booming market flooded with all sorts of coffee products, finding the right one can be challenging. Our guide lists the key features to consider when selecting an infuser that'll transform your morning brew. Let's dive in!

Material Quality

Pay close attention to the quality of the material used in the construction of the cold brew infuser. Superior materials not only ensure durability but also influence the taste of your brew. Stainless steel and glass infusers are particularly popular for their non-reactive properties, leaving your brew free from any metallic or plastic taste. A good infuser should withstand repeated use and maintain its integrity over time.

Size and Capacity

Consider the size and capacity of the cold brew infuser. For individual use, a smaller infuser might suffice. However, if you're avid about your cold brew and often serve it to friends and family, a larger capacity model would be a better fit. The size should also be convenient for storage in your refrigerator or kitchen cabinet.

Ease of Use

The best cold brew infuser should simplify your brewing process, not complicate it. Look for designs that are easy to assemble, fill, and clean. The infuser should offer a clear way to control the brewing process, such as adjustable settings for brewing time or coffee concentration. A well-designed handle that facilitates pouring is also a significant consideration.

Filter Quality

The magic of cold brew coffee lies in the slow extraction process. A good filter plays a crucial role in this, permitting water flow while restraining the coffee grounds. Look for an infuser with a high-quality filter that guarantees a grit-free brew. A reusable filter is also preferable for its eco-friendliness and cost-effectiveness.

Budget

While you might be tempted to go for the cheapest cold brew infuser available, remember that quality often comes at a cost. Balance your budget with the features you desire in an infuser. Investing in a higher-priced model with excellent material quality, ease of use, and a good filter could save you money in the long run by avoiding frequent replacements.

Brand Reputation

Finally, consider the reputation of the brand before purchasing a cold brew infuser. A well-established brand often means reliable customer service and a trustworthy warranty. Read reviews and seek recommendations. Brands that consistently deliver high-quality products will have a loyal customer base and positive feedback.

FAQs

How do I use a cold brew infuser?
To use a cold brew infuser, you need to add your coffee grounds or tea leaves into the infuser basket, then fill the carafe with cold water. Secure the lid and let the mixture steep in the refrigerator for about 12 to 24 hours. After this, remove the infuser basket and the cold brew is ready to be served.
How do I clean a cold brew infuser?
Cold brew infusers should be cleaned after each use. Remove the infuser basket and dispose the used coffee grounds or tea leaves. Wash all parts with warm soapy water and rinse thoroughly. Some models are dishwasher safe, but you should check the product instructions to confirm.
What kind of coffee should I use for the infuser?
You can use any type of coffee you like for your cold brew infuser. However, medium to coarsely ground coffee is usually recommended for optimal flavor extraction.
Why does the coffee from my cold brew infuser taste weak?
If the coffee from your cold brew infuser tastes weak, it could be due to several factors. These include not using enough coffee grounds, using coffee that is ground too finely, or steeping the coffee for a shorter time than recommended. Adjusting these variables should improve the taste.
Can I use a cold brew infuser to make hot coffee?
Yes, you can use your cold brew concentrate to make hot coffee. Simply heat up the diluted concentrate on the stove or in a microwave. Be careful not to let it boil, as this can result in a bitter taste.
Why is my cold brew infuser leaking?
If your cold brew infuser is leaking, it may be because the lid or seal is not secure. Check to make sure all parts are correctly assembled and the lid is screwed or snapped in place firmly. If the problem persists, the seal may be damaged and need replacement.
