How do you clean a cold brew coffee maker?

Clean it after every batch. Coffee oils and fine grounds go rancid, and leftovers change the taste of the next brew. Always follow your maker’s manual, because materials differ between glass, plastic and stainless models.

Every-batch cleaning

1. Throw away the grounds. Tap the filter or bag upside down over the bin or compost to loosen them.
2. Rinse the filter under water, outside first and then inside.
3. Wash the jar, lid and other parts by hand in warm soapy water.
4. If there is a tap or hose, run warm water through it until it runs clear.
5. Rinse until no soap remains. Leftover soap affects taste.
6. Dry with a soft towel or air dry completely before storing.

How do you clean a cold brew filter?

The right method depends on the filter. Mesh and stainless filters can be rinsed and brushed gently. Felt filters should be rinsed with cold water right after use and dried completely before the next batch, because felt holds moisture. Paper filters are single use.

Deeper cleaning

Do this every so often, or whenever the flow slows down. A KitchenAid cold brew maker, for example, comes apart so you can release the bottom door, remove the hose and tap, and wash each part. Make sure seals are back in place when you reassemble.

What should you avoid?

• The dishwasher, unless your manual allows it. KitchenAid says to hand wash its cold brew maker.
• Abrasive scrubbers that scratch plastic or glass.
• Strong-smelling soap, which can leave a scent.
• Putting it away damp, which leads to mold or musty smells.

Quick troubleshooting

• Slow dripping: filter clogged. Rinse it or replace it.
• Sour or stale taste: old oils. Do a deeper wash.
• Musty smell: not fully dry. Air dry with parts apart.
