Cold brew is an easy coffee habit to build, and a fridge-friendly pitcher makes it easier. You add coarse grounds and water, keep the container in the refrigerator, and come back to smooth, low-acid coffee. The catch is that shelf space is limited, so size and shape matter as much as the brewing method. Below are four cold brew makers, from a slim one-liter glass pitcher to a giant five-gallon batch brewer. Each is covered by what it does best, where it falls short and who should buy it. For food safety, keep your cold brew refrigerated, plan to drink it within about a week, and wash every part thoroughly between batches.

Our Picks: Best cold brew coffee makers for refrigerator reviews
Original Grind Co. 1 Gallon: A Big Glass Pitcher With a Spigot
This is the pick for volume. A full gallon makes up to 16 cups in one go, which is far more than the Hario or the compact OXO and saves you from brewing every few days. If you live with other coffee drinkers, or you bring cold brew to a family gathering or office, that capacity matters more than any single feature.
The glass pitcher has an adjustable stainless steel spigot, so you can pour a glass without lifting a heavy container. The ultra-fine mesh filter is meant to keep grit out of the cup. The listing says the air-tight lid keeps coffee fresh in the refrigerator for up to 2 weeks, but a safer habit is to finish a batch within about a week. The infuser setup also works for iced tea, fruit water and herbal blends, which gives it a use beyond coffee. The trade-off is size: a full gallon pitcher takes real shelf space, so measure your fridge first and keep it refrigerated.
Pros:
- Largest home-size pitcher here, up to 16 cups
- Adjustable spigot makes pouring easy
- Air-tight lid for fridge storage
- Infuser also works for tea and fruit water
Cons:
- Takes a lot of refrigerator space when full
Verdict: Choose this gallon pitcher if you brew for several people and want a spigot for easy pouring.
Hario Mizudashi: The Simple Glass Pitcher That Brews in the Fridge
The Hario is the easiest design in this group to understand. You put ground coffee in the fine mesh basket, add water and leave it in the refrigerator. There is no switch, no valve and no concentrate math. Brew and serve from the same heatproof glass server, then lift out the removable filter and rinse it.
It gives you room to adjust the flavor. A coarse grind gives a lighter, more delicate cup, while a finer grind brings more body and strength. The slender spout pours slowly and steadily. Capacity is 1000 mL, about five cups, so it fits a one or two person household better than a crowd. The glass is made in Japan, and the body is slim at 138 by 94 by 294 mm, which gives it a narrow footprint for a refrigerator shelf. Pick it if you want the simplest setup and a pitcher you can serve from.
Pros:
- Very simple: add grounds and water, then refrigerate
- Removable filter is easy to rinse and reuse
- Slim body and slender spout for steady pouring
- Grind size lets you adjust strength
Cons:
- Smaller capacity of about five cups
Verdict: Choose the Hario if you want the simplest setup and a pitcher you can brew and serve from.
Cold Brew Cube: A 5-Gallon Batch Brewer Shaped for Fridge Shelves
This one is built for people who go through a lot of coffee. It brews up to about 14 qt per batch, depending on your coffee-to-water ratio, which is much more than any other pick here. The square 11.8 by 11.8 by 16 inch shape is meant to use refrigerator shelf space better than a round container would.
Dual filtration is the other standout. Two stages capture grounds and reduce fine sediment, so you should see less grit in the glass. The offset spigot drains more of the brewed coffee and leaves less liquid behind at the bottom. The listing says it works for ready-to-drink cold brew or concentrate. This is a big vessel, so it makes sense only if you have the fridge space and drink enough coffee to finish a batch. For a single person, the smaller OXO or Hario models are more practical.
Pros:
- Huge batch size of up to about 14 qt
- Dual filtration helps reduce sediment
- Offset spigot drains more of the batch
- Square shape uses shelf space well
Cons:
- Too large for most households and needs plenty of shelf space
Verdict: Choose the Cold Brew Cube only if you drink a lot of coffee and have the fridge space for a giant batch.
OXO Brew Compact 24 oz: A Concentrate Maker for Crowded Fridges
This OXO is made for tight spaces. The 24 oz container makes concentrate for up to seven drinks, and it is compact enough to brew on a countertop or in the refrigerator, so it can steep right on a fridge shelf.
The workflow is easy. Draining starts automatically when you place the brewer on the carafe, so there is no switch to manage. The Rainmaker still spreads water evenly over the grounds, and a lid protects the brew while it steeps. A stopper with a silicone seal keeps the concentrate fresh in the borosilicate glass carafe, and the brewer and carafe nest for storage. You can use the concentrate for hot or iced coffee. The trade-off is that it brews less per batch than the gallon pitchers, and you need to dilute the concentrate.
Pros:
- Small footprint for counters and fridges
- Draining starts automatically when placed on the carafe
- Stopper with silicone seal keeps concentrate fresh
- Brewer and carafe nest for storage
Cons:
- Makes only enough for up to seven drinks per batch
Verdict: Choose the compact OXO if you like the Rainmaker system but need something small.
How to Choose the Right Cold Brew Maker for Your Refrigerator
Start With Fridge Space
Before you look at features, measure the shelf or door where the brewer will sit. The Hario is slim at 138 by 94 by 294 mm, which suits a tight shelf. The Cold Brew Cube is 11.8 by 11.8 by 16 inches, so it needs a real shelf with room to spare. A pitcher that does not fit will end up on the counter, and then the refrigerator advantage is gone.
Match Capacity to How Much You Drink
A one-person household can finish a 1000 mL pitcher or a concentrate batch from the compact OXO in a few days. A family that drinks coffee every morning will do better with the gallon pitcher. The five-gallon cube only makes sense for heavy daily use or for sharing with a lot of people. Bigger is not better if you cannot finish a batch while it still tastes fresh.
Concentrate or Ready-to-Drink
The compact OXO makes concentrate that you dilute with water or milk. That stretches each batch further and takes less fridge space per serving. Pitcher-style brewers like the Hario and the gallon pitcher are more of a brew and pour setup. Think about how you drink your coffee, since concentrate gives you a stronger base and more control over each glass.
Filters and Thorough Cleaning
All four of these brewers use a reusable filter, so there is no paper to buy. That makes cleaning more important, because coffee oils and fine grounds build up in any filter. Take every part apart after each batch and wash it well, including the filter, lid, spigot and stopper. Let everything dry fully before the next brew.
Spigot, Spout and Pouring
A spigot lets you fill a glass without lifting a heavy pitcher. It matters most on the gallon pitcher and the five-gallon cube. For smaller glass pitchers, a slender spout gives you slow, steady pouring. An offset spigot, as on the Cube, can help drain more of the brew.
Materials and Safe Storage
Glass is easy to see through and easy to wash, which makes it a good fit for the refrigerator. A tight lid or stopper helps keep the coffee fresh. Even so, cold brew is a perishable drink. Keep it refrigerated at all times, label the date you brewed it, and plan to drink it within about a week. If it smells or tastes off, throw it out.
Frequently Asked Questions
How long should I steep cold brew?
Steeping time depends on the brewer and your taste. A common range is 12 to 24 hours. Start in the middle and adjust: a shorter steep is lighter, and a longer one is stronger. Keep the brewer in the refrigerator while it steeps.
What grind size should I use?
Use a coarse grind for most cold brew makers. The Hario maker notes that a coarse grind gives a lighter, more delicate coffee, while a finer grind makes a cup with more body and strength.
Can I brew cold brew in the refrigerator?
Yes. The Hario is made for exactly that: add grounds and water, then leave it in the refrigerator. The compact OXO is meant for brewing on a countertop or in a refrigerator, and the Cube is sized to use fridge shelf space well.
How long does cold brew stay fresh in the fridge?
Plan to drink it within about a week, and keep it sealed and refrigerated the whole time. The Original Grind Co. listing mentions up to 2 weeks with its air-tight lid, but a shorter window is the safer choice at home.
How should I clean a cold brew maker?
Disassemble it after every batch and wash the filter, lid, spigot and container thoroughly, then let the parts dry. Removable filters, like the one on the Hario, are quick to rinse. Do not top up an old batch with new coffee.
What is the difference between concentrate and ready-to-drink cold brew?
Concentrate is a stronger brew that you dilute with water or milk, so one batch makes more drinks. Ready-to-drink cold brew is brewed at a strength you can pour straight into a glass. The compact OXO makes concentrate, and the Cube can make either one.
Can I make iced tea or fruit water in a cold brew maker?
Some can. The Original Grind Co. pitcher has an infuser system for iced tea, fruit-infused water and herbal infusions. Wash it well between coffee and other drinks.
Final Recommendation
For most small households, the OXO Brew Compact is a smart fit for crowded fridges, and the Hario Mizudashi is the simplest option for one or two drinkers. If you brew for a crowd, the Original Grind Co. gallon pitcher gives you the most capacity in a home-friendly size. Choose the Cold Brew Cube only if you drink a lot of coffee and have the fridge space to match. Whichever you pick, keep it refrigerated, drink it within about a week and clean it thoroughly each time.
