Buying coffee online: how to choose instant coffee, iced coffee or Americano without making the wrong choice

If you want to buy coffee online, you’ll soon come across dozens of varieties: instant coffee, soluble coffee, coffee sticks, ready-to-drink iced coffee and flavoured Americano. The packaging can make a product look simple and light, while its ingredients, serving size or storage requirements may not suit the way you plan to use it.

Use these checks to compare coffee based on practical, objective information rather than just the brand name or eye-catching claims.

Common pitfalls when buying coffee online

1. “Less sugar” doesn’t mean sugar-free

A product with less sugar may still contain sugar. The ingredients list and nutrition table give you a clearer picture than the front of the pack. For example, according to the product information, UCC Blend Coffee Less Sugar contains coffee, sugar, milk powder and sweetener. It contains 2.4 grams of carbohydrates per stated serving.

If you’re specifically looking for sugar-free coffee, check that the “sugars” entry in the nutrition table is zero. This can vary between instant coffee and ready-to-drink coffee containing milk, syrup or flavourings.

2. A larger pack doesn’t automatically mean a lower cost per cup

Always compare:

  • the total weight or volume;
  • the number of servings;
  • the recommended amount of water or milk;
  • the price per serving;
  • how long it keeps after opening.

A jar or bottle may look like better value, but coffee sticks can be more practical if you want to avoid waste. A box of 30 servings is best suited to daily coffee drinkers. If you only drink it occasionally, a smaller pack may make more sense.

3. “Americano” can mean different things

Americano coffee isn’t always the same product. It may be soluble coffee powder, concentrated coffee syrup or a ready-to-drink beverage in a pouch or can. So check whether you’re buying just coffee powder or a drink containing water, sugar, milk ingredients and flavourings.

For ready-to-drink iced coffee, it’s also important to refrigerate it after opening. Follow the storage instructions on the packaging.

The key details to compare

Ingredients and allergens

Start by checking the ingredients. 100% coffee powder indicates a simple blend, while café au lait, vanilla and caramel varieties often contain milk powder, sugar, flavourings or stabilisers.

If you have an allergy or intolerance, pay particular attention to milk and soya. For example, AGF Cafe Au Lait Unsweetened Coffee lists milk and soya as allergens. Always check the latest packaging, especially for imported products. Product information on a website may change, and the packaging has the most up-to-date instructions.

Preparation and serving size

Instant coffee is convenient because you don’t need a coffee machine. The SLAB TOWN sticks contain 2.8 grams of coffee powder per serving, with around 200 ml of hot or cold water or milk. According to the product information, each Luckin Genki Ball sachet contains 2 grams and is made with around 150 ml of water.

The amount of water affects the strength. If you use more than recommended, the flavour will be milder. Individually wrapped coffee sticks are easy to store and measure out, making them handy for the office, travel or your cupboard at home.

Sugar, energy and flavour

Compare the nutritional information per 100 ml or per serving, and check what it refers to. For concentrates, the values may apply to the prepared drink. For example, Nescafé Espresso Concentrate Caramel and Vanilla list 57 kcal and 7.4 grams of sugar per 100 ml of prepared product.

So vanilla-flavoured coffee or caramel-flavoured coffee may contain more sugar than black instant coffee. For flavoured drinks, it’s worth checking the ingredients and serving size as well as the flavour.

Frequently asked questions about buying coffee online

Which coffee is handy for the office?

Instant coffee sticks are practical when several people drink coffee and you don’t want to use a coffee machine. The servings are easy to share out, and all you need is water or milk. Check how many sticks are in the pack and how much water is recommended per serving.

How long does coffee bought online keep?

The best-before date is printed on the packaging. Store dry instant coffee in a cool, dry, dark place, following the instructions. Once opened, ready-to-drink coffee should be kept in the fridge and used within the stated period, as directed on the label.

Is sugar-free coffee always low in calories?

Not necessarily. Black instant coffee usually contains few ingredients, but a café au lait variety may contain milk powder or lactose. So check the nutritional information per serving. Products flavoured with vanilla, caramel or hazelnut may also contain added sugar and flavourings.
