OXO Compact Cold Brew

Concentrate brewer with a rainmaker lid and a one-touch valve into a glass carafe. Paper filter over the mesh, so the cleanest cold brew of the immersion systems.

Roast	Grind	Coffee	Water	Time
light	medium-coarse	20 g	160 ml	900:00
medium	medium-coarse	20 g	160 ml	780:00
dark	medium-coarse	19 g	160 ml	660:00

Per 250 ml cup. Makes 2–6 at a time.

What goes wrong

Skipping the paper filter (silty, loses the system's only real advantage), dumping water in without the rainmaker lid (channels through dry pockets, hollow and weak), coarse Toddy-style grind on a 12-hour steep (under-extracted, thin), forgetting it is concentrate and drinking it neat

Care schedule

1 task for this machine.

Clean the cold-brew filter

Monthly

Cold brew runs for 12 to 20 hours at room temperature with the filter holding wet grounds the whole time. A filter that has been rinsed but never cleaned develops a musty note that carries straight into the concentrate.

What you need

Hot water. Washing-up liquid for mesh filters, water only for felt. A soft brush. A sealed container for the fridge if the filter is felt.

What goes wrong

Soap on a felt filter. Letting a felt filter dry out. Cleaning the vessel and forgetting the spigot. Storing everything damp and sealed, which is how the mustiness starts.

The procedure

Empty the grounds and rinse the filter under hot water straight after decanting, working from the clean side outward.
