Cold Brew Coffee Maker 64 oz Mason Jar Review: Skip the $6 Coffees

You are spending $6 per cold brew at coffee shops when you could make 8 servings at home for the same price. The math is brutal: if you buy cold brew twice a week, you are burning through $624 per year on something you can make in your kitchen for pennies per cup.

This 64 oz mason jar cold brew system with a stainless steel filter costs $16.99 and has earned 4,391 reviews averaging 4.5 stars on Amazon. We scored it 93 out of 100 in our discovery process because it solves the cold brew problem without the $40-60 price tag that most dedicated brewers demand.

What it is

This is a 64 ounce glass mason jar with a removable stainless steel mesh filter, a pour spout lid, and a handle. The filter sits inside the jar and holds your coffee grounds while the jar fills with cold water. After 12-24 hours in your refrigerator, you pull the filter out and you have cold brew concentrate ready to pour.

The jar is made from heavy duty glass that can handle temperature changes. The filter is 304 stainless steel mesh, fine enough to keep grounds out of your finished brew. The lid has a built-in pour spout and seals with a silicone gasket to prevent leaks. The handle is molded into the glass, not glued on.

Capacity is 64 ounces, which translates to 8 cups of finished cold brew concentrate or 16 cups of diluted ready-to-drink cold brew. The filter holds approximately 3/4 cup of coarse ground coffee.

Who it's for

This cold brew maker is for people who drink cold brew regularly and want to stop paying coffee shop prices. If you buy cold brew more than once per week, this pays for itself in three weeks.

It works for households that drink multiple cups per day because the 64 ounce capacity gives you enough concentrate for a full week. The mason jar design fits standard refrigerator doors and takes up less space than most dedicated cold brew systems.

You should skip this if you only drink hot coffee, if you do not have refrigerator space for a 64 ounce jar, or if you need single-serve portions. This is a batch brewer. You make a large amount at once and store it.

Skip it if you want a system that brews in under 12 hours. Cold brew requires time. If you need coffee immediately, this is not your solution.

How we scored it

We gave this cold brew maker a discovery score of 93 out of 100. That score comes from our algorithm that weighs price against review volume, rating stability, and category competition.

The 4,391 reviews at 4.5 stars tell us this product has been tested by thousands of real users and the rating has held steady over time. Products with high review counts and ratings above 4.4 pass our quality threshold.

The $16.99 price point is 60% lower than comparable cold brew systems from OXO and Takeya that sell for $40-50. We flag products that deliver similar functionality at a fraction of the cost because that is the core of the dont-overpay pillar.

The mason jar design is a bonus. Glass does not absorb flavors or odors the way plastic can, and the wide mouth makes cleaning easier than narrow-neck brewers.

The pros

• 64 ounce capacity makes enough cold brew concentrate for 8-10 servings, which lasts most households 5-7 days
• Stainless steel filter is fine enough to eliminate grounds without requiring paper filters, saving ongoing costs
• Glass construction does not absorb coffee oils or flavors, so your brew tastes clean every time
• Pour spout lid with handle makes serving easy without removing the entire lid or lifting a heavy jar awkwardly
• Wide mouth opening allows you to reach inside for thorough cleaning, unlike narrow-neck brewers that trap residue
• Airtight silicone seal prevents leaks when the jar is tipped or stored on its side in a crowded refrigerator
• Mason jar design fits standard refrigerator door shelves, taking up less space than most dedicated cold brew towers

The cons

• Filter requires manual removal after brewing, and wet coffee grounds are messy to dispose of without dripping
• Glass is heavy when full, and the 64 ounce capacity makes the jar weigh over 4 pounds, which can be awkward for people with grip strength issues
• No measurement markings on the jar, so you have to estimate water levels or use a separate measuring cup

The verdict

This cold brew maker does exactly what it claims to do at a price that makes sense. You add coarse ground coffee to the filter, fill the jar with cold water, wait 12-24 hours, and you have cold brew concentrate. The process is simple and the results are consistent.

The $16.99 price is the key advantage. Dedicated cold brew systems from established brands cost $40-60 and do not produce noticeably better coffee. The mason jar approach gives you the same end product without the premium price.

If you drink cold brew regularly, this pays for itself in three weeks compared to buying from coffee shops. If you are currently using a cheaper method like a French press or a DIY jar with cheesecloth, this upgrade gives you a cleaner brew with less mess.

We recommend this for anyone who wants to make cold brew at home without overpaying for a dedicated system. The 4,391 reviews at 4.5 stars back up the quality, and the price makes it a low-risk purchase.

FAQ

How long does cold brew last in this jar? Cold brew concentrate stays fresh for 10-14 days when stored in a sealed jar in the refrigerator. The airtight lid on this system helps maintain freshness.

Can you use this jar for hot coffee? The glass can handle hot liquids, but the cold brew process requires cold water and time. If you want to brew hot coffee, use a different method and store the finished coffee in this jar.

What grind size works best? Coarse ground coffee works best for cold brew. Fine grinds pass through the mesh filter and make your brew muddy. Buy coarse ground coffee or grind your own beans on the coarsest setting.

How much coffee do you need per batch? Use 3/4 cup of coarse ground coffee for a full 64 ounce batch. This produces concentrate that you dilute 1:1 with water or milk. Adjust the ratio if you want stronger or weaker brew.

Is the filter dishwasher safe? Yes, the stainless steel filter and glass jar are both dishwasher safe. The silicone gasket in the lid should be hand washed to extend its life.
