Buying coffee online: how to choose instant coffee and ready-to-drink varieties

Buying coffee online is convenient when you want to quickly replenish your supplies for home, the office or on the go. You’ll find instant coffee, coffee sticks, 3-in-1 coffee, iced coffee and international varieties such as Vietnamese coffee. At the same time, the choice can feel overwhelming. Attractive packaging tells you little about sugar content, serving size or caffeine.

This practical guide helps you compare products using verifiable information. That way, you can choose a coffee variety that suits your taste, when you plan to drink it and your dietary preferences.

Three common pitfalls when buying coffee

1. “Creamy” coffee with lots of sugar

Coffee with milk, creamer or a caramel flavour can taste smooth and approachable, but it may also contain a relatively high amount of sugar. With 3-in-1 coffee, the sugar and creamer have already been added, so you cannot adjust the proportions yourself.

So don’t just look at the name. Also check:

  • sugars per serving or per 100 ml;
  • where sugar appears in the ingredients list;
  • the difference between a powdered drink and black instant coffee;
  • whether sweeteners are used alongside sugar.

A product described as “smooth”, “rich” or “caramel” mainly refers to the flavour experience. It is not an objective measure of coffee strength or nutritional value.

2. Comparing caffeine on different bases

The amount of caffeine is not always clearly displayed on the front. For ready-to-drink coffee, it is usually stated per 100 ml, while the packaging may contain 190, 230 or 300 ml, for example. So calculate the amount for the full pack.

A product with 42 mg of caffeine per 100 ml contains approximately 101 mg of caffeine per pack at 240 ml. At 52 mg per 100 ml, 240 ml amounts to approximately 125 mg. The exact amount may vary by product and pack size. Always check the label.

This is especially important for coffee on the go. Also look out for warnings for children, pregnant women, breastfeeding women and people who are sensitive to caffeine, where these appear on the packaging.

3. Underestimating shelf life and storage

Instant coffee is generally easy to store at room temperature, provided the packaging remains dry, cool and tightly sealed. Ready-to-drink coffee requires more attention:

  • check that a can, bottle or carton is undamaged;
  • follow the storage instructions on the packaging;
  • keep opened milk- or coffee-based drinks chilled;
  • check the stated best-before or use-by date;
  • drink an opened product within the period stated on the label.

With a multipack, it is also sensible to try one pack first. A large box is only good value if you genuinely enjoy the flavour and use the products within their shelf life.

What should you look for when buying coffee online?

Start by considering when you’ll drink it

For a quick cup at home or in the office, instant coffee, soluble coffee and coffee sticks are practical choices. You only need hot water. A jar such as Douwe Egberts Aroma Rood Instant Coffee gives you more freedom to adjust the strength and, according to the product information, is made from a blend of Arabica and Robusta beans.

For drinking on the go, individual sachets or ready-to-drink coffee are more convenient. Consider NESCAFÉ 3-in-1, Trung Nguyen G7 or a can of UCC. You won’t need to take a coffee machine, spoon or extra ingredients with you.

Compare the ingredients

Black coffee without sugar generally has a different composition from coffee with milk or a 3-in-1 mix. For example, Luckin Genki Ball lists freeze-dried Arabica coffee powder and 0 grams of sugar and fat, according to the product information. You can mix the sticks with hot or cold water and add milk or plant-based milk yourself.

With 3-in-1 coffee, the coffee, creamer and sugar are combined in advance. According to the product description, NESCAFÉ 3-in-1 contains 53% sugar and 7.6% instant coffee. Trung Nguyen G7 combines coffee, creamer and sugar in 16-gram sachets. These varieties are primarily designed for convenience and a smooth, sweet flavour.

Check allergens and nutritional information

Milk, soya, gluten and fish may be present in coffee products or their ingredients. Always check the current ingredients list on the packaging, even if an earlier product description gave different information. For example, Slinmy Instant Coffee Mix with Collagen states that the product contains milk and fish.

A brand claim about a product feature is not a general guarantee. According to the brand’s own information, a product may contain Arabica coffee, a particular amount of caffeine or require a specific preparation method, for example. Before buying, always use the official product information and the label as your main reference.

Frequently asked questions about buying coffee online

Which coffee is convenient for drinking on the go?

Coffee sticks and ready-to-drink coffee are practical choices for drinking on the go. Sachets such as NESCAFÉ 3-in-1 or Trung Nguyen G7 take up little space and only require hot water. You can drink iced coffee from a can or bottle straight away. For chilled varieties, check the storage instructions and choose a pack you can finish in one go.

Is instant coffee cheaper than ready-to-drink coffee?

That depends on the price per serving. Compare the total contents, the number of servings and any extras you need, such as milk or sugar. A jar of instant coffee can be good value when you measure it out yourself. A multipack of iced coffee may cost more per drinking occasion, but it does offer convenience and fixed serving sizes.

How should I store instant coffee and iced coffee?

Store instant coffee sealed in a cool, dry place away from direct sunlight and moisture. According to the product label, unopened ready-to-drink coffee can often be stored at room temperature. Once opened, a product containing milk or coffee extract will usually need to be refrigerated. Always follow the latest instructions on the packaging.
