The short answer
Buy the Toddy if you drink cold brew regularly - concentrate keeps about two weeks and one batch goes a long way. Buy the OXO if you want to pour straight over ice with no dilution. Buy the Hario Mizudashi if you are trying cold brew for the first time.
Concentrate or ready-to-drink
This is the only decision that really matters, and most buying advice skips past it. The two approaches use different amounts of coffee, keep for different lengths of time, and suit different habits.

1. Top pick
Toddy Cold Brew System
Mid tier · A concentrate brewer: a high coffee-to-water ratio steeped long, then diluted to taste.
Concentrate that keeps about two weeks, so one brewing session covers a fortnight.
The Toddy brews at a heavy coffee-to-water ratio for 18 to 24 hours, producing a concentrate you dilute per glass rather than a finished drink.
That is the feature, and it is a bigger one than it sounds. Concentrate keeps in the fridge for roughly two weeks, and one batch dilutes into dozens of servings. If you drink cold brew daily, you brew twice a month instead of every other day.
Diluting per glass also means you set the strength each time. Strong over ice in the morning, longer with milk in the afternoon, and the same batch handles both - which no ready-to-drink brewer can do.
It filters through a felt pad, which produces a very smooth, very low-acid result that is noticeably rounder than mesh-filtered cold brew.
Specification
- Type
- Concentrate system
- Steep time
- 18-24 hours for full extraction
- Fridge life
- Concentrate keeps about two weeks
- Yield
- One batch dilutes into dozens of servings
What it does well
- Concentrate keeps for around two weeks, so one brew covers a fortnight
- You dilute to taste per glass rather than being stuck with one strength
- The felt filter produces a very low-acid, very smooth result
Where it gives ground
- Uses a lot of coffee per batch, because concentrate needs a heavy ratio
- The reusable felt filter has to be stored wet and replaced periodically
- 18-24 hours means planning a day ahead
Skip it if
Skip it if you drink cold brew occasionally. Concentrate needs a heavy dose of coffee per batch, and brewing a big one for two glasses is wasteful.
2. Best ready-to-drink
OXO Good Grips Cold Brew Coffee Maker
Mid tier · A ready-to-drink cold brewer with a rainmaker lid and a controlled drain.
Brews at normal strength and drains cleanly, so it pours straight over ice.
The OXO brews at a normal ratio over 12 to 18 hours in 32 oz batches, so what comes out is finished coffee rather than concentrate. There is no arithmetic at the point of pouring.
Its rainmaker lid is a genuine design improvement rather than a marketing one. Cold water poured into a bed of grounds tends to punch through in one spot and leave dry pockets; a distributing lid wets the bed evenly, which is most of what separates good cold brew from flat cold brew.
The controlled drain matters too. Straining cold brew through a cloth is messy and squeezes fines through; a switch that opens a filtered valve is cleaner in both senses.
The trade-offs are volume and shelf life. Finished cold brew keeps days rather than the fortnight concentrate manages, and 32 oz per batch means brewing more often.
Specification
- Type
- Ready to drink
- Batch size
- 32 oz
- Steep time
- 12-18 hours
What it does well
- Brews at a normal ratio, so it pours straight over ice with no dilution step
- The rain-style lid wets the bed evenly rather than dumping water in one spot
- Controlled drain means you are not straining through a cloth
Where it gives ground
- Ready-to-drink keeps a shorter time than concentrate - days rather than weeks
- 32 oz per batch means brewing more often than a concentrate system
- More parts to wash than a single-vessel brewer
Skip it if
Skip it if you want one brew to last a fortnight. Ready-to-drink does not keep the way concentrate does.
3. Best value
Hario Mizudashi Cold Brew Pot
Budget tier · A one-piece fridge jug with a mesh basket - the simplest cold brewer that works.
A fridge jug with a mesh basket, and honestly most of what the expensive ones do.
The Mizudashi is three parts: a 1,000 ml glass jug, a lid, and a tall mesh filter basket. You put up to 80 g of coarsely ground coffee in the basket, fill with water, and leave it 8 to 12 hours.
It is by a wide margin the cheapest good cold brewer, and the gap in the cup between this and the expensive systems is much smaller than the gap in price. Cold brew is a forgiving method: long steeping at low temperature does most of the work.
It brews and pours from the same vessel, and it fits in a fridge door, which is a bigger practical advantage than it sounds when the alternative is a bucket occupying a shelf.
The mesh is fine but it is mesh, so a grinder producing lots of dust will put that dust in your cup. And 1 L is a day or two of iced coffee, not a week.
Specification
- Capacity
- 1,000 ml
- Dose
- Up to 80 g of coarsely ground coffee
- Steep time
- 8-12 hours
- Type
- Ready to drink
What it does well
- Cheapest genuinely good cold brewer, by a wide margin
- Fits in a fridge door and pours from the same vessel it brews in
- Three parts total - jug, lid, filter basket
Where it gives ground
- Fine mesh only, so a grinder producing lots of fines will show in the cup
- 1 L is one or two days of iced coffee, not a week
- Glass, in a fridge, among other things
Skip it if
Skip it if you drink a lot of cold brew. Refilling a 1 L jug every other day gets tedious, and a concentrate system solves exactly that.
4. Best if you also want hot coffee
Breville Precision Brewer
Upper-mid tier · A programmable drip brewer that exposes bloom time, temperature and flow rate.
A full drip machine with a genuine cold brew mode, so one appliance covers both.
Most cold brew makers do one thing. The Precision Brewer is a 60 oz drip machine with a dedicated Cold Brew mode alongside Gold, Fast, Strong, Over Ice and a fully custom My Brew setting.
Its My Brew control is the reason it is here rather than a novelty inclusion: you set bloom time, brew temperature and flow rate independently, which is more control than any other automatic machine offers.
For a kitchen where the real constraint is counter space and outlets, replacing a drip machine and a cold brew jug with one device is a genuine argument, and it makes very good hot coffee.
It is far more expensive than any dedicated cold brewer, and its cold brew is good rather than exceptional. Judged only on cold brew this is not the right purchase.
Specification
- Capacity
- 60 oz
- Certification
- Gold Cup setting meets SCA home-brewer requirements
- Custom control
- My Brew: bloom time, brew temperature, flow rate
- Modes
- Gold, Fast, Strong, Over Ice, Cold Brew, My Brew
- Pour-over
- Optional adapter for a V60 or Kalita Wave
- Size
- 9 in D x 14 in W x 16 in H, 10.63 lb
What it does well
- The only common drip machine that hands you the brew variables directly
- The pour-over adapter turns it into an automated dripper stand
- Cold-brew mode is genuinely useful rather than a marketing mode
Where it gives ground
- The flexibility is wasted if you only ever press Gold
- Large and heavy
- The adapter kit is a separate purchase on most listings
Skip it if
Skip it if you only want cold brew. You are paying for a full drip machine you did not ask for - see drip coffee makers.
5. Skip this
Bodum Chambord French Press
Budget tier · The classic 34 oz French press: borosilicate carafe in a chrome-plated steel frame.
It works, and it ties up your French press for eighteen hours.
A French press does make cold brew. Coarse grounds, cold water, twelve hours in the fridge, then plunge. As a way of finding out whether you like the drink at all, it is free if you already own one.
The problems are practical rather than fundamental. The press is occupied for the whole steep, so you cannot make hot coffee in it. If it is your only brewer, that is half a day without coffee.
Its screen is coarse and there is no lip seal, so fines get into the cup and continue extracting in the fridge. Cold brew's appeal is smoothness, and this works against exactly that.
Volume is the last issue. A press makes one batch of finished cold brew - not concentrate - so you are back at it constantly.
Specification
- Capacity
- 34 oz, 3-4 cups
- Carafe
- Borosilicate glass
- Filter
- Stainless steel mesh plunger
- Frame
- Chrome-plated steel, made in Portugal
What it does well
- No paper, no capsules, no consumables at all
- Full-bodied cup that no paper filter can produce
- Every part is replaceable and cheap
Where it gives ground
- Metal mesh lets fines and oils through - that is the trade, not a defect
- Punishes an inconsistent grinder harder than any other brewer
- Glass carafe in a household with a tile floor
Skip it if
Skip the workaround if you have decided you like cold brew. A dedicated brewer frees your press and filters better.
Why cold brew tastes different
Cold water extracts differently from hot water, not just more slowly. Many of the compounds responsible for perceived acidity and bitterness are considerably less soluble at low temperature, so they largely stay in the grounds.
That is why cold brew tastes smooth, round and low in acidity regardless of the beans, and also why it tastes flatter - the bright, distinct notes that make a good pour-over interesting are among the things left behind. Cold brew is a forgiving method that narrows the range of what you can taste.
Grind coarse, and mean it
Every brewer here separates coffee from water with a mesh or a cloth after a long steep. Fine particles pass through both, and once they are in the jug they keep extracting for as long as the coffee sits in the fridge.
That is why cold brew made with a blade grinder turns harsh after a couple of days while the same beans from a burr grinder stay smooth. Grind coarse, and grind evenly - the second matters more.
Step 1
Grind coarse
Coarser than French press. You are extracting for twelve hours, not four minutes.
Step 2
Wet the whole bed
Add water gradually rather than in one pour. Dry pockets stay dry for the entire steep.
Step 3
Steep in the fridge
Room temperature works and extracts faster, but the fridge is more predictable and safer over a long steep.
Step 4
Separate completely
Get the grounds out at the end. Coffee left on the bed keeps extracting and turns bitter over the following days.
Step 5
Store sealed
Cold brew picks up fridge smells readily. A sealed container matters more than it does for hot coffee.
How long it keeps
Concentrate keeps roughly two weeks because its high dissolved solids content is a hostile environment for spoilage and because you are diluting fresh each time. Ready-to-drink is finished coffee and behaves like it - good for a few days, tired after that.
If you find yourself throwing cold brew away, you bought the wrong type rather than the wrong brewer.
