Best Cold Brew Coffee Makers

The OXO Good Grips Cold Brew at $50. It is the only one here that addresses the two real failure points: a rainmaker lid distributes water across the whole bed of grounds rather than letting it channel down the middle, and a brew-release switch lets you drain on your schedule. It cuts off automatically when you lift the carafe, so you cannot over-extract by leaving it running. The concentrate lands in a borosilicate glass carafe. The catch, and it is a fair one, is that the brewing chamber itself is plastic.

The Hario Mizudashi at $21 for one or two people, or the County Line Kitchen at $35 for a household. Both steep in glass, which is the part that matters, since the coffee is in contact with the vessel for the better part of a day. Neither is fully plastic-free — lids and filter frames still are — and no cold brew maker we have found is. If the plastic question is what brought you here, our plastic-free guide covers how far you can actually take it across brewing methods.

Twelve to twenty-four hours in the fridge. Twelve gives a lighter, brighter cup; a full day gives more body and more of the chocolatey heaviness people associate with cold brew. Past a day you are mostly extracting bitterness, not strength. The practical answer is to put it on in the evening and strain it when you get up, which lands you in the right window without thinking about it.

It depends on the maker, and it changes how much you get. The OXO brews a concentrate, so what comes out is diluted with water or milk and a full carafe makes considerably more than it looks like. The Hario brews ready-to-drink at ordinary strength, so what you pour is what you get. Neither is better — but concentrate stores in less fridge space and keeps longer, which matters if you brew once a week rather than every other day.

Coarse, and even matters more than coarse. Fines are what turn cold brew silty and harsh, and a long steep gives them all the time in the world to do it — which is why the same beans taste muddy from a blade grinder and clean from a burr. If you are deciding between spending on the maker or the grinder, spend it on the grinder. Every maker here is a jar with a filter; none of them can fix a bad grind.

Brewed cold brew is good for about a week refrigerated, and concentrate a little longer. What kills it is air rather than time, which is the argument for the Takeya at $35: its lid genuinely seals, so it can lie on its side in a packed fridge and the coffee does not go flat and cardboardy by day three. An open jar covered with a plate will be noticeably worse by then.

Yes, and it works fine — coarse grounds, cold water, steep in the fridge, press and pour. Two caveats. A press screen lets more fines through than a dedicated cold brew filter, so the result is siltier, and you lose the press for anything else while it steeps. If you already own a press, try it before buying anything. If you like cold brew enough to make it weekly, a dedicated maker with a sealing lid is a real improvement.
