Buying coffee without making a mistake: how to choose beans, capsules or instant coffee

Buying coffee online seems straightforward, but the range can vary considerably in flavour, format, brewing method and compatibility. Attractive packaging or a familiar brand name doesn’t always tell you everything you need to know. If you focus only on discounts or an intensity rating, you could end up with coffee that doesn’t fit your machine, goes stale too quickly or doesn’t suit your taste.

Use this practical guide to check the details that really matter before you order.

Common pitfalls when buying coffee

1. Misinterpreting an intensity rating

A score of, say, 6 or 7 usually indicates how strong the coffee tastes, but it isn’t a universal unit of measurement. Brands use different scales, so an intensity rating of 7 from one brand may not taste the same as a 7 from another.

So, also look at:

• the roast: light, medium or dark;
• the blend: Arabica coffee, Robusta coffee or a blend;
• the recommended brewing method: espresso, lungo or filter;
• flavour descriptions such as fruity, chocolatey, spicy or mild.

2. Ordering the wrong capsules for your coffee machine

Not every capsule fits every machine. Nespresso capsules and Dolce Gusto capsules use different systems. Capsules for L'OR Barista aren’t necessarily suitable for every machine either.

Before buying, check:

• the exact capsule system used by your machine;
• whether the product is suitable for Nespresso Original, L'OR Barista or NESCAFÉ Dolce Gusto;
• the recommended amount of water;
• whether you’re buying black coffee or a milk-based variety.

A product page may list compatible machines, but always check your own machine’s manual too.

3. Looking only at the price per pack

A 500-gram pack of coffee beans may seem more expensive than twenty capsules, but the cost per cup could work out differently. So, calculate the price per serving. For capsules and coffee pods, check the number of cups per pack and the recommended serving size too.

Storage time and how quickly you use the coffee also matter when buying beans. A large pack is practical for a household or office, but less suitable if you only drink coffee now and then.

Important specifications to check

Coffee format and brewing method

First, choose the format that suits your daily routine:

• Coffee beans: suitable for a bean-to-cup machine, espresso machine or coffee grinder. You can adjust the grind for espresso, moka or filter coffee.
• Ground coffee: suitable for a filter coffee machine, cafetière or certain espresso machines, depending on the grind.
• Coffee capsules: quick and mess-free, but only suitable for a compatible system.
• Coffee pods: designed for machines such as Senseo. Check that the pack specifically says they’re suitable for your machine.
• Instant coffee: handy at the office, when travelling or whenever speed matters more than an elaborate brewing process.

Arabica, Robusta or a blend

Arabica coffee is often described as smoother and more aromatic, while Robusta can give coffee more body and a stronger character. These are general flavour profiles, not a guarantee of a particular experience. The roast, origin and ratio of beans also make a difference.

A blend of Arabica and Robusta can work well in espressos with plenty of body and crema. If you prefer a milder, more aromatic cup, look for products made with 100% Arabica.

Packaging, quantity and best-before date

Check:

• the weight in grams or the number of capsules;
• that the packaging is intact;
• the best-before information on the pack;
• storage advice after opening.

Store coffee in a cool, dry place, away from direct sunlight, heat and moisture. Seal opened packs tightly. For coffee beans and ground coffee, an airtight seal helps preserve the aroma for longer.

Frequently asked questions about buying coffee

Which coffee is suitable for a Nespresso machine?

Choose capsules that clearly state they’re suitable for Nespresso Original or for your specific machine. For example, Douwe Egberts and Starbucks offer capsules listed as suitable for Nespresso systems in their product information. Always check the compatibility details before ordering.

Which is better value: coffee beans or capsules?

It depends on how much coffee you drink, the purchase price and the amount used per cup. Coffee beans are often a good choice for households and offices that make several cups a day. Capsules are quick and convenient, but compare the number of capsules and the quantity per pack with the number of servings you need.

How should I store coffee after opening?

Keep coffee in a tightly sealed pack in a cool, dry place, away from direct sunlight, heat and moisture. Follow the instructions on the label. Also check the packaging and best-before information whenever you order, before using the product.
