Best ground coffee from the supermarket revealed

Looking for a better morning brew? We asked four independent coffee experts to blind-taste supermarket and big-brand ground coffees to uncover the best – and the ones you might want to leave on the shelf. 

Our test included ground coffee from well-known brands such as Cafédirect and Illy, as well as supermarkets, including M&S, Lidl, Sainsbury's and Tesco.

We found that when you spend a bit extra, you can get a deliciously smooth morning brew with our top-scorer from Cafédirect, which was a Best Buy.

Read on to find out how all the coffees compare, and what the experts thought of your nearest supermarket's offering.

Coffee strength and roast levels

All the coffee in our test had a strength rating of three on the packet. This broadly reflects roast intensity and flavour profile, rather than caffeine content. 

Unfortunately, there isn't a consistent scale for coffee strength, so one brand's 'three' won't necessarily be the same strength as another brand's three. For example, one brand may have a one-to-six scale, while another has a 10-point system.

Use the descriptions on the pack to guide you. Medium-roast coffees are lighter and smoother than continental or Italian-style coffees, which tend to be darker roasts.

Not sure what type of roast you like? Think about beer (stay with us): if you enjoy a golden lager, you’ll probably enjoy a lighter roast. Or perhaps you enjoy a deep, rich stout; if so, opt for a dark roast.

It’s also a common misconception that a darker roast has higher caffeine levels. Bean type is actually the main factor for caffeine content. For example, robusta beans have more caffeine than arabica beans. So if you're looking for coffee that packs a punch, opt for robusta-heavy blends.

How sustainable is coffee?

The coffee sector doesn’t have a great reputation when it comes to sustainability. It has been associated with deforestation, biodiversity loss and detrimental effects on indigenous communities. 

When selecting ground coffee, look for Fairtrade and organic certifications, which are independently audited to ensure quality and aim to support more sustainable farming practices. Also, check for detailed sourcing information, indicating that the beans are sourced more ethically and that growers are paid fairly.

All the coffees in our test display either the Fairtrade International logo or provide farm and sourcing information.

How healthy is coffee?

Meet our nutrition expert

Shefalee Loth, Which? principal researcher and nutritionist

Shefalee is a public health nutritionist with 20 years' experience, who has worked for the NHS, The London School of Hygiene & Tropical Medicine and World Cancer Research Fund.

'In the past few years, there have been several large-scale studies linking regular consumption of coffee (around three to five cups a day for healthy adults) to numerous health benefits.

'This is linked to a reduced risk of some conditions, including: a reduced risk of some cancers, stroke, heart failure, coronary heart disease, dementia and Alzheimer's disease, Parkinson's disease, respiratory illness and type 2 diabetes. 

'Coffee has also been associated with greater longevity, reduced inflammation and improved liver health. These benefits are largely attributed to polyphenols, which are naturally found in coffee (and other foods) and act as antioxidants. These polyphenols are thought to help regulate blood sugar by reducing blood glucose spikes after meals and improving the body’s glucose handling. Plus, they may help to ‘mop up’ free radicals, which damage DNA and are linked to cancer and cognitive decline, and promote the growth of good bacteria in your gut. 

'The good news is that the health benefits of coffee are seen in both regular and decaf varieties.

'Caffeine is also why you might need to stop drinking coffee early in the afternoon as you risk disturbed sleep. New research suggests leaving around seven hours between your last coffee and bedtime may help you fall asleep more easily.

'You don’t have to drink your coffee black to benefit. Adding milk or fortified plant-based milk can add calcium and other nutrients. The research also shows that instant coffee offers similar benefits to freshly ground, so you don’t need to spend lots.'

How we tested ground coffee 

During our testing, we made more than 50 cups of coffee, each brewed with the exact same volume of water and at the perfect temperature of 95°C (so we didn't burn the brew).

Our experts sipped the coffees both with and without milk, to assess how the flavours held up to a dash of dairy. Then each coffee brand was assessed for flavour, aroma, body, and aftertaste. The experts also told us what they liked and disliked about each one and described those delicious tasting notes you get with a good cup of coffee.

The taste test was blind, so the experts didn’t know which brand they were trying. The order in which they tasted the coffee was fully randomised to avoid bias, and the results were analysed by our in-house stats team.

The overall score was based on:

• 40% flavour
• 25% body
• 20% aftertaste 
• 15% aroma

These weightings are based on how our experts rank the importance of different attributes of coffee.
