Buying coffee: how to choose the right coffee without wasting your money

Do you want to buy coffee online for home, the office, or on the go? You’ll quickly come across terms like Arabica, Robusta, dark roast, intense and premium. These words don’t always tell you what you’ll actually get in your cup. A convenient package or well-known brand name can also hide the fact that the coffee isn’t suited to your brewing method or daily use.

With this practical guide, you focus on verifiable product information: brewing method, ingredients, size, flavour profile and storage instructions. This way, you can compare ground coffee, instant coffee, coffee capsules and ready-to-drink coffee in a way that suits your situation.

Three common pitfalls when buying coffee

1. Confusing “strong” with a dark roast

A dark roast often gives a fuller and more intense flavour profile, but it doesn’t automatically tell you how much caffeine the coffee contains. The ratio of Arabica coffee to Robusta coffee, the dosage and the brewing method also play a role.

So look at the roast, the described flavour segment and the bean type. A product with 100% Arabica may be described as smoother and more aromatic, while a blend with Robusta often has a stronger, spicier character.

2. Choosing a package that doesn’t suit your machine

Ground coffee isn’t universally suitable for every machine. Filter coffee requires a different grind to espresso coffee. Coffee capsules are also often tied to a specific system. So check before you buy whether the capsules are compatible with your machine. For example, the Douwe Egberts Lungo capsules in this selection are suitable for Nespresso machines, while filter coffee is intended for a filter machine, cafetière or similar brewing method.

3. Only looking at the price per package

A 250g bag of coffee might seem like a bargain, but the real cost depends on the dosage. A 500g product can be handy for a household with several coffee drinkers, but it loses its aroma more quickly after opening if the package isn’t sealed properly. For occasional use, sticks, capsules or small jars of instant coffee can be more practical.

So also compare:

  • the number of cups you get from a package;
  • the amount needed per cup;
  • the shelf life and storage method;
  • the amount of waste from capsules and individual packaging.

Important specifications to check

Brewing form and grind

First, choose the form that fits your routine:

  • Ground coffee: suitable for filter coffee, cafetière or certain espresso machines, depending on the grind.
  • Instant coffee: quick to make with hot water and handy at the office or on the go.
  • Coffee capsules: simple and portion-controlled, but check compatibility with your machine.
  • Ready-to-drink coffee: ready to drink, without a coffee machine. Watch out for milk, sugar and the need for refrigeration after opening.
  • Coffee concentrate: to be mixed with water or milk for, for example, an Americano, latte or iced coffee.

The description “espresso” doesn’t always mean the product is only suitable for an espresso machine. Check the specific brewing instructions on the product page and packaging.

Bean type and flavour

Arabica coffee is often associated with a milder, aromatic taste. Robusta coffee generally has a stronger, spicier character. A blend can combine both qualities. According to the product description, Lavazza Qualità Rossa consists of Arabica and Robusta beans and is described as full and velvety, with notes of chocolate and dried fruit.

For Vietnamese coffee, Robusta is often a recognisable component. According to the product description, Trung Nguyen Creative 1 uses Culi-Robusta and is described as dark and strong, suitable for hot coffee and Vietnamese iced coffee. If you want to make Turkish coffee, you need very finely ground coffee. According to the description, Kurukahveci Turk Kahvesi is made from 100% Arabica and is intended for a traditional preparation where the coffee grounds remain in the cup.

Ingredients, allergens and nutritional information

Black coffee without sugar doesn’t automatically mean it contains no other additives. Read the ingredients list. According to the label, UCC MAJOR Black Coffee 185 ml contains water and 8% coffee and states 0 grams of sugar per 100 ml. Starbucks Tripleshot Espresso Iced Coffee, on the other hand, contains milk and sugar; according to the product information, it has 8.5 grams of sugar per 100 ml and 47 mg of caffeine per 100 ml.

Also look out for allergens. Milk can be present in iced coffee or coffee drinks with milk. With capsules and ground coffee, only coffee is often listed as an ingredient, but always check the current packaging. If you’re unsure about allergens, the product labelling is definitive.

Storing coffee and ordering online

Store ground coffee, instant coffee and capsules in a cool, dry place, away from direct sunlight and out of the way of heat and moisture. Seal the packaging well after use. According to the label, a ready-to-drink product must be kept refrigerated after opening and used within the stated period.

Before you order coffee online, check:

  1. whether the size suits your consumption;
  2. whether the brewing method matches your machine;
  3. whether milk, sugar or other ingredients are desired;
  4. whether the packaging is undamaged;
  5. whether the shelf-life information on the packaging matches your plans.

For a household that drinks filter coffee daily, Douwe Egberts Mocca 250 grams, Lavazza Qualità Rossa 250 grams or a 500g pack could be practical. If you want to try different flavours, it’s better to start with a smaller pack, instant coffee or a box of capsules.

Frequently asked questions about buying coffee

What’s a convenient coffee for the office?

Instant coffee, coffee capsules and ready-to-drink coffee require little preparation. Only choose capsules if the machine is compatible. For a shared filter machine, ground coffee is often more convenient, because several people can use the same pot.

How long does coffee stay good after opening?

This varies per product and packaging. Stick to the stated best-before date and seal the packaging well. With ground coffee and instant coffee, the aroma and flavour are generally better preserved when air, moisture, light and heat are limited. The instructions on the label are definitive.

Is coffee without sugar always low in calories?

According to many product labels, black coffee without sugar contains little energy, but always check the nutritional value of the specific product. Iced coffee and coffee drinks with milk can contain sugar and fat. For example, Starbucks Tripleshot Espresso Iced Coffee lists milk and sugar as ingredients.
