OXO Brew Cold Brew Coffee Maker

A cold brew coffee maker is built to take the bitterness and high acidity out of your morning iced coffee by swapping rapid heat extraction for unhurried, room-temperature steeping. The OXO Brew tackles this process with an overnight steep-and-release system that transforms coarse coffee grounds into rich, low-acid concentrate capable of yielding up to 14 individual drinks. By blending your finished batch with water or milk, you get immediate access to chilled coffee throughout the week without having to brew from scratch each morning.

Even water distribution is essential for consistent flavor, and the unit achieves this through its specialized Rainmaker lid. Sitting directly above the brewing chamber, this perforated top disperses poured water evenly across coarse grounds rather than letting it channel through a single point. This design maintains balanced saturation while the mixture steeps for its recommended 12 to 24 hours, ensuring that flavor extraction remains uniform throughout the entire coffee bed.

Filtration management is equally well considered thanks to an intuitive brew-release switch. When the steeping window is complete, engaging the switch directs the liquid through an ultra-fine stainless steel mesh filter that catches fine sediment without requiring disposable paper replacements. The system also features a smart mechanical safeguard: if you pull the carafe away from the base while draining, filtration stops automatically, protecting countertops from stray drips and preventing over-extraction in the chamber.

The finished concentrate drains directly into a 32 oz borosilicate glass carafe that includes clear measurement markings along the side. The carafe is shaped to slide conveniently onto refrigerator shelves, keeping your supply cold and ready to pour. Maintenance requires some attention to care guidelines, as only the glass carafe and stainless steel filter are dishwasher safe; the remaining body pieces require hand washing. Additionally, the unit does take up counter space while steeping, though it conveniently nests together when packed away.

Verdict: For households that want smooth, low-acid iced coffee on tap, this cold brew coffee maker provides reliable extraction, clean pouring, and a durable glass storage carafe. It is an excellent choice for batch brewers who can plan their coffee 12 to 24 hours in advance, while those looking for instant single-cup preparation will want to look elsewhere.

• Carafe Capacity: 32 oz of coffee concentrate (up to 14 drinks)
• Carafe Material: Borosilicate glass with measurement markings
• Filter Type: Reusable ultra-fine stainless steel mesh
• Steeping Duration: 12 to 24 hours

A great fit if you:

• Drink iced coffee frequently and prefer keeping up to 32 oz of concentrate chilled and ready to mix with milk or water.
• Want to eliminate recurring purchases of paper coffee filters by relying on a reusable stainless steel mesh filter.
• Value tidy kitchen organization and want a brewing system that nests into a compact footprint when stored away.
• Appreciate mess-free draining controls that automatically stop the flow of coffee if the carafe is removed.

Consider something else if you:

• Need a cup of coffee immediately in the morning rather than waiting through a 12 to 24 hour steeping period.
• Prefer appliances where every single component can be safely placed into a household dishwasher.

Confirm on the listing:

• Check whether the package includes an airtight carafe lid or stopper for extended refrigerator storage.
• Measure your kitchen countertops and cabinet clearance to verify that the brewing unit fits comfortably during active use.
• Verify refrigerator shelf heights to ensure the 32 oz borosilicate glass carafe fits upright in your fridge door or shelves.
• Review the product listing to confirm that the stainless steel mesh filter and filter cap are supplied in the box.

How to compare your options: Focus on carafe construction, filtration style, and draining mechanisms when evaluating cold brewers. This model features durable borosilicate glass, an ultra-fine metal mesh that eliminates ongoing paper filter costs, and an automatic shutoff drain valve that prevents spills during decanting.

Start by grinding your coffee to a coarse consistency before adding it to the brewing chamber, as coarse grounds promote optimal saturation beneath the Rainmaker lid.

Pour your brewing water directly through the Rainmaker top to allow the perforated pattern to saturate the grounds evenly, and let the mixture steep undisturbed for 12 to 24 hours.

When steeping finishes, set the borosilicate carafe underneath the spout and activate the brew-release switch to filter the concentrate smoothly into the glass vessel.

Wash the glass carafe and stainless steel mesh filter in the dishwasher, but hand wash all other parts to keep the components in prime condition. Once dry, unscrew the filter cap and nest the pieces together to save shelf space.

How many servings does one batch make?
