The Australian cold brew market has grown up fast. Five years ago, ordering cold brew at a Sydney café got you a raised eyebrow; today it's on the menu next to the long black. That shift has been matched by a parallel rise in home cold brew gear — and two pieces in particular have become the default benchmarks: the OXO Brew Compact Cold Brew Coffee Maker and the OXO Brew Rapid Cold Brewer.
Both are made by the same company. Both produce excellent cold brew. They're not, however, the same product — and choosing the wrong one for your kitchen or your travel routine will leave you disappointed. Here's the straight comparison.
In this guide
What is cold brew (vs iced coffee)?
Cold brew and iced coffee aren't the same drink, even though they end up in the same glass with the same ice. Iced coffee is brewed hot — espresso or filter — and then cooled. Cold brew is brewed with cold water from the start, steeped for 12-24 hours, and never heated. That changes the chemistry.
The chemistry change matters because the compounds that produce bitterness, harshness and acidity in coffee are mostly heat-extracted. Brew with cold water and you extract sweetness, body and chocolatey notes without the sharpness. The result is a smoother, lower-acid drink that holds beautifully in the fridge for up to two weeks as concentrate.
Key takeaway: Cold brew is naturally sweeter, smoother and lower in acidity than iced coffee — and once you have the gear, it costs a fraction of café prices to make at home.
Why OXO?
OXO has spent 30+ years building kitchen gear around one principle — "universal design" — which translates as: every product should work for anyone, regardless of hand strength, dexterity or experience. That philosophy is unusually well-suited to coffee gear, because the failure mode of a bad brewer is always the same: fiddly. OXO doesn't do fiddly.
Both cold brew makers in the OXO range use heavy borosilicate glass carafes, fine stainless-steel mesh filters with paper filter compatibility, and what OXO calls a "Rainmaker" perforated lid that distributes water evenly over the grounds for consistent extraction. It's an unglamorous detail that makes a measurable difference.
Rapid Cold Brewer vs Compact Cold Brew Maker
Here's the comparison most Australian buyers care about.
OXO Brew Rapid Cold Brewer — $89.95 (RRP $119)
The Rapid is OXO's faster system. It uses a pressure-driven N2 chamber (no electricity, no batteries) to compress the brew time from 12-24 hours down to about 10 minutes for a single cup of cold brew concentrate, or roughly 20 minutes for a litre. It's the best option if you make cold brew on demand rather than batching.
The trade-off: it's a single-serve focus, and the brewing chamber is smaller. If you drink one cold brew a day and don't want to plan ahead, this is the one.
OXO Brew Compact Cold Brew Coffee Maker — $79.95 (RRP $110)
The Compact is the traditional steep-and-store cold brewer, reimagined for small Australian kitchens. It brews ~700ml of concentrate (enough for around 5-6 cold brews) in 12-24 hours, then the brewing container nests inside the glass carafe for storage — the whole assembled unit fits on a single fridge shelf.
This is the right buy if you batch your week's cold brew on a Sunday and drink from the fridge through the week. The concentrate keeps for up to two weeks; the compact storage means it doesn't dominate a shelf.
"Rapid is for the impatient single-cup drinker. Compact is for the planner who wants a week of cold brew waiting in the fridge. Same brand, same quality, completely different use case."
How to make great cold brew at home
The recipe is forgiving but a few details matter. Start here:
- Beans: Use a medium-to-dark roast. Chocolatey, nutty, low-acid origins (Brazil, Sumatra, Honduras) work beautifully. Light roasts can taste under-extracted in cold brew.
- Grind: Coarse — coarser than French press. If your grind is too fine, the result is muddy and over-extracted.
- Ratio: Start at 1:8 coffee to water by weight for concentrate. So 100g coffee to 800g water.
- Time: 12-18 hours at room temperature, or 18-24 hours in the fridge. Longer steeps trend sweeter and stronger.
- Serve: Dilute the concentrate 1:1 with water, milk or sparkling water over ice.
💡 Tip: Cold brew concentrate makes a brilliant base for espresso martinis. One shot concentrate, one shot vodka, half shot coffee liqueur, shake hard, no need to pull espresso.
Cold brew for travel & small spaces
The Compact Cold Brew Maker is genuinely apartment-and-Airbnb friendly. The assembled unit stores in under 20cm of fridge height, weighs roughly 1.2kg empty, and the borosilicate carafe doubles as a serving jug. We've packed it into a road-trip kit more than once — pre-loaded with grounds and water in the morning, ready to pour by the time you've reached the next stop.
The Rapid is even more portable in form factor — it's the size of a tall coffee plunger — but it does need a single N2 capsule per brew, which is a consumable to keep stocked. If you mostly drink cold brew at home in measured volumes, the Compact wins on running cost.
Our recommendation
For most Australian households, the OXO Brew Compact Cold Brew Coffee Maker ($79.95) is the smarter buy. It costs less, has no consumables beyond paper filters (which are optional), produces a week's worth of concentrate per batch, and stores beautifully in a small kitchen. Brew on Sunday, drink Monday to Friday.
Choose the Rapid Cold Brewer ($89.95) instead if you're a single-cup drinker, you don't plan ahead, or you want cold brew the day you decide you want it. Both are excellent — they just answer different questions.

Is cold brew stronger than regular coffee?
As a concentrate, yes — it's typically 2-3 times stronger than drip coffee. Once diluted 1:1 for serving, the caffeine content is comparable to a standard long black. Concentrate undiluted is roughly equivalent to a double espresso in caffeine.
How long does cold brew last in the fridge?
Cold brew concentrate keeps for up to two weeks in a sealed glass container in the fridge. Once diluted with water or milk, drink within 2-3 days for best flavour.
Can I use the OXO cold brew makers with paper filters?
Yes. Both the Rapid and Compact accept compatible paper filters that drop into the stainless-steel mesh. Paper filters produce a cleaner, brighter cup; the mesh alone gives a fuller-bodied, slightly heavier brew. Try both.
What grind size for OXO cold brew?
Coarse — slightly coarser than French press. Pre-ground "cold brew" labelled coffee from most Australian roasters is calibrated for this. If you grind at home, aim for the size of breadcrumbs rather than sand.
Is the Rapid Cold Brewer worth the extra cost over the Compact?
Only if speed matters more than batch size. The Rapid produces cold brew in ~10 minutes per cup using N2 pressure; the Compact takes 12-24 hours but brews a week's supply at once. Most cold brew drinkers are happier with the Compact's batch approach.
Can I make hot coffee with the OXO cold brew makers?
The cold brew concentrate can be diluted with hot water for a smooth, low-acid "hot brew" cup — sometimes called a Japanese-style flash brew. The brewers themselves aren't designed for hot brewing in the traditional sense.
