Choosing instant coffee: a practical guide to flavour, price and convenience

A cup of coffee without a coffee machine sounds simple enough: open a sachet, add hot water and stir. Yet many shoppers end up buying a product that doesn't suit their taste or daily routine. Some instant coffees are almost entirely coffee, while a 3-in-1 version can be mostly sugar and creamer. Portion sizes and preparation methods also vary considerably.

As Joybuy Product Recommendation Officer, I filter the most important product information so you can compare marketing claims with verifiable facts. That way, you can avoid a bad buy at home, in the office or on the go.

Three common pitfalls with instant coffee

1. Expecting a coffee taste, but mostly tasting sugar

With 3-in-1 coffee, cappuccino instant coffee and latte varieties, the coffee, milk powder or creamer and sugar are often already mixed together. That's convenient, but not every sachet has the same ratio. For example, the product information for NESCAFÉ 3-in-1 Smooth & Rich states 53% sugar and 7.6% instant coffee. Douwe Egberts 3-in-1 states 10% instant coffee and 59 grams of sugar per 100 grams.

If you want to decide for yourself how much milk or sugar to add, choose pure instant coffee. Always check the ingredients list and nutritional information rather than just the name on the front.

2. Confusing "café-style" with coffee from an espresso machine

Terms like "crema layer", "latte" or "cappuccino" often describe the intended drinking style, not a preparation under espresso pressure. A sachet is convenient and can give a frothy layer, but it doesn't replace a coffee machine in terms of preparation method.

With espresso sticks, the recommended amount of water is important. The Nescafé Espressostick, for instance, uses 1.8 grams of coffee with around 60 ml of hot, not boiling, water. If you add much more water, the drink will naturally become milder.

3. Buying a large multipack without checking allergens and portions

A pack with lots of coffee sachets may seem good value, but first look at the number of portions, the weight per sachet and the ingredients. Some varieties contain milk, lactose, soya or ingredients based on palm or coconut oil. If you have an allergy or intolerance, the packaging is your guide; product information can change.

Also pay attention to storage: keep instant coffee cool and dry, away from direct sunlight and moisture. Don't use a sachet if the packaging is damaged.

Important specifications to compare

Pure coffee or a blended mix

Check the first ingredients:

• Instant coffee or freeze-dried coffee: generally suitable if you want to add your own milk and sugar.
• 3-in-1: coffee, creamer and sugar in one portion; quick to make, but often sweeter.
• Cappuccino, mocha or latte macchiato instant coffee: usually a mix with milk powder, creamer, sugar and flavourings.
• Decaf instant coffee: contains caffeine-free instant coffee, but check the exact product description and allergens on the packaging.

A product like SLAB TOWN states 100% coffee powder and portions of 2.8 grams. Luckin Genki Ball states freeze-dried coffee and 0 grams of sugar per 100 grams according to the supplied product information. This makes these products different from a sweet coffee sachet.

Water amount and portion size

The recommended amount of water determines the strength and volume. Examples from the product information:

• Nescafé Espressostick: around 60 ml of water per sachet.
• Nescafé Mocca: around 120 ml of water.
• Many latte, cappuccino and 3-in-1 sachets: around 150 ml of water.
• SLAB TOWN: around 200 ml of water, optionally with milk.

A sachet of 16 to 22 grams contains other components besides coffee, such as sugar and creamer. A stick of 1.8 to 2.8 grams usually consists of a much smaller amount of pure coffee. So don't just compare the number of sachets, but also grams per portion and the total amount of coffee.

Caffeine, milk and nutritional value

Not every product states the caffeine content in milligrams. So don't rely on words like "strong", "rich" or "smooth". According to the product information, Trung Nguyen G7 3-in-1 states that the product contains caffeine. The Nescafé Gold Cappuccino Unsweetened Decaf is described as caffeine-free; always check the current packaging before buying.

If you want to avoid milk, don't just look at "non-dairy creamer". Some varieties contain milk protein, whey or sodium caseinate. The allergen declaration is more important here than the product name.

Storing and preparing instant coffee

Ideally, use hot water that hasn't been boiling for a long time, especially with espresso sticks where the manufacturer may specify a particular temperature or amount. Stir well and drink the prepared coffee straight away. Store an opened multipack in a dry, well-sealed container so that moisture doesn't get into the powder.

Want to make a latte with pure instant coffee? First dissolve the coffee in a small amount of water, then add warm milk or plant-based milk. With a ready-made latte or cappuccino, you only need to add the stated amount of water.

Frequently asked questions about instant coffee

How long does instant coffee keep?

The best-before information is on the packaging. Unopened sticks are generally protected from air and moisture. After opening, moisture is the main concern: store a jar or bag well sealed and don't use a product with damaged packaging.

Is instant coffee cheaper than coffee from a machine?

That depends on the price per portion, the weight and the variety you choose. Pure coffee in a larger pack can be better value per cup than individual latte or cappuccino sachets. Sachets, on the other hand, save time and make a coffee machine, filters and separate milk or sugar unnecessary. Compare the price per portion, not just the price of the pack.

Which instant coffee is suitable for on the go?

Choose instant coffee sticks or coffee sachets with a clearly stated portion and preparation method. For a milky coffee, 3-in-1, cappuccino and latte varieties are practical. For more control over flavour and sugar, espresso sticks or pure instant coffee are more convenient. If you're sensitive to caffeine or have allergies, always check the product packaging.
