I can’t live without my morning coffee fix. It’s an essential that gives me a boost and signals the start of my day. I’m not alone in how I enjoy this daily ritual, and I, like many others, would feel lost without it.

However, you may notice that your coffee has been tasting a bit “off” lately, even after trying new beans and adjusting the grind. But before you splurge on a fancy new coffee machine, try these expert cleaning tips. They might just fix your coffee’s flavor.

Upgrade the taste of your coffee

Improving the taste of your coffee doesn’t always require new equipment; it can simply come down to maintenance habits, according to Sarah Dewison, cleaning expert at North West Commercial Cleans Ltd, who’s partnered with Redrow.

Give it a daily clean
“To maintain optimal performance, your coffee machine should be cleaned at the end of each day,” says Dewison.

Before you start cleaning your machine, she says switch it off and allow it to cool. Then she says, “Remove and rinse all detachable components such as the portafilter, drip tray, and water reservoir using dish soap and warm water.”

The next step is to clean the exterior. “Wipe down external surfaces with a clean, damp cloth with washing up liquid and warm water to remove coffee residue and spills. This prevents build-up and keeps the machine looking professional.”

Don’t neglect the grinder and filter

There are other parts of your coffee machine that shouldn't be ignored. “For machines with built-in grinders or filters, empty and clean these components regularly. Coffee grounds left in the system can become stale and impact flavor,” says Dewison.

She also suggests using a soft brush, such as a clean makeup brush or a paintbrush, to remove residue, while also being careful to avoid water contact with electrical components.

Apart from giving your coffee machine a daily clean and checking the grinder and filter, there are a few other areas that could be impacting the taste of your brew.

Don’t skip descaling

Limescale and coffee oils can build up inside the machine, affecting both taste and performance. Use a manufacturer-approved solution or a natural mix of water, white vinegar and lemon, followed by a thorough rinse to remove any remaining residue.

However, before you clean your coffee maker with vinegar, always check the manual for your machine, as different manufacturers have different guidelines for cleaning their products.

How often should you descale your coffee maker? It can be quite hard to tell, but Tom's Guide’s Coffee Lab host, Erin Bashford, judges when her kettle needs descaling, and she cleans her coffee machine at the same time.

Check the milk

To avoid bacterial growth, keep the milk system clean. Purge and wipe the milk frother after each use and soak any removable parts daily. You really don’t need to be spending out on coffee shop lattes to get a premium coffee taste. By making a few tweaks to your coffee machine cleaning routine, you can savor the taste of flavorsome at-home brew.

Better tasting coffee without buying new

Cleaning your coffee machine is one way to ensure your coffee tastes its best. But you can also make a few other tweaks to improve its flavor.

1. Keep your beans and grinds fresh. Store your coffee in an opaque, airtight container at room temperature; a dark pantry is ideal. Beans stay fresher for longer than grinds, so grind just what you need. If you buy ground coffee, keep it well sealed and use the date on the pack.

2. Use a coffee scale to measure your beans accurately; it will eliminate the guesswork and help you achieve consistency across your brew, including the flavor.

3. Grind your coffee correctly to achieve the perfect grind for your choice of brew. The grind size should depend on your brewing method. Espresso requires a fine grind to cause resistance against the machine's high pressure, while French press needs coarser grinds for a slow brew.
