How to Make Instant Coffee
Simple Black Instant Coffee
Recipe
Black Instant Coffee
- Makes:
- 1 serving
- Time:
- 3 minutes; water ready
Ingredients
- 2 g plain instant coffee
- 200 ml (6.8 US fl oz) hot water, divided into 30 ml (1 US fl oz) and 170 ml (5.7 US fl oz)
Equipment
- Kettle
- Scale
- Liquid measure
- Spoon
- Heatproof mug, at least 250 ml (8.5 US fl oz)
Method
- Put 2 g plain instant coffee in a heatproof mug of at least 250 ml (8.5 US fl oz) capacity.
- Add 30 ml (1 US fl oz) hot water and stir until the coffee dissolves.
- Add the remaining 170 ml (5.7 US fl oz) hot water. Stir and let it cool to a comfortable sipping temperature.
Estimated nutrition: 7 kcal · 0 g total sugar. Per black coffee, with no milk or sugar.
Follow the product's water-temperature advice when available. The coffee has already been extracted during manufacture; there is no need to steep it like fresh grounds. Stirring is for dissolving the solids.
What Does Instant Coffee Taste Like?
A darker blend can lean toward toast, cocoa and a dry, roasty finish; a lighter specialty instant may have more fruit or floral character. Use the roast and tasting description to choose the style you enjoy.
Plain soluble coffee gives a cup without loose grounds. Milk softens the bitter edge and adds body, while a concentrated instant base keeps more coffee flavor in an iced milk drink.
I buy a small jar when trying a new instant coffee, because a low price per cup is little comfort if I do not enjoy finishing it.
Instant Coffee Ratio and Taste Adjustments
How Much Instant Coffee Per Cup?
Keep the water at 200 ml (6.8 US fl oz) while you adjust the powder. Use the table to adjust flavor, keeping your product’s directions in mind.

| Plain instant coffee | Water | Useful next step |
|---|---|---|
| 1.5 g | 200 ml (6.8 US fl oz) | Try this if the 2 g cup tastes too heavy |
| 2 g | 200 ml (6.8 US fl oz) | Starting recipe on this page |
| 2.5 g | 200 ml (6.8 US fl oz) | Try this if the 2 g cup tastes too weak |
A darker or more concentrated cup can taste stronger without telling you its caffeine content. Roast, blend and formulation also affect the flavor. If a coffee tastes unpleasant at several sensible doses, changing the product may help more than adding another spoonful.
Start with one teaspoon if you have no scale. NESCAFÉ's serving guide gives 1.8 g per teaspoon with 200 ml (6.8 US fl oz) water, a useful starting point for our 2 g serving. Keep the same spoon and mug as you adjust the strength.
Instant Coffee vs. Ground Coffee
Plain instant dissolves; ordinary grounds need brewing. Grinding beans more finely does not turn them into soluble coffee. A coffee mix can look like powder while containing much more than coffee.

| Product | What to check | How to use it |
|---|---|---|
| Plain instant coffee | Coffee-only ingredient list | Dissolve the measured dose in water |
| Instant espresso powder | Beverage or baking directions | Use the stated dose; a concentrated instant drink is not machine-extracted espresso |
| Ground coffee | Grind size and brewing method | Brew with suitable equipment; it will not dissolve like instant |
| Three-in-one sachet | Sugar, creamer, milk allergens and serving size | Use the packet directions; weigh the whole mix if calculating nutrition |
| Soluble and microground blend | Presence of actual ground coffee | Follow its directions; some fine sediment may remain |
Ready-to-drink coffee is already liquid. Instant is a dry ingredient you reconstitute, which makes the water, milk and sweetness easy to control separately.
Café Bustelo Espresso Instant Coffee is a dark-roast soluble product that dissolves in hot or cold water or milk. The US jar directs you to stir one heaping teaspoon into 177 ml (6 US fl oz) hot or cold water or milk for one cup. Here, espresso-style describes the coffee’s flavor rather than a freshly pressure-brewed shot.
Ginseng coffee, or caffè al ginseng, is another product-label question: a soluble mix can combine coffee with ginseng extract, sugar and creamer. Check its own dose and ingredients before applying the plain-instant figures here.
Iced Instant Coffee
For a quick black iced version, dissolve 2 g instant coffee in 30 ml (1 US fl oz) hot water, add 150 ml (5.1 US fl oz) cold water, then pour over 80 g (2.8 oz) ice in a 350 ml (11.8 US fl oz) glass. Stir and serve promptly. The glass needs room for ice: 180 ml (6.1 US fl oz) liquid water goes in before the ice melts.
If it becomes too weak as the ice melts, first try less cold water while keeping the coffee dose fixed. Increasing the coffee instead also increases the caffeine contribution of that product. Some products are designed to dissolve in cold water; use their directions and allow enough stirring time.
Cold instant coffee is not cold brew. The coffee was extracted before drying; cold water now dissolves it. Cold brew steeps ground coffee in cool water.
For a milky version, dissolve the coffee first, then replace some of the cold water with cold milk. Count the milk from its own label. For a whipped sweet topping rather than a stirred drink, follow Dalgona coffee. For a hot beaten coffee paste mixed into milk, see Indian beaten coffee.
For a hot coffee-and-milk drink, see café con leche or Cuban café con leche. Prepare the plain instant separately, then measure the finished coffee for that drink rather than treating a spoonful of dry powder as a coffee serving.
Instant Coffee Caffeine, Calories and Sugar
How Much Caffeine Is in Instant Coffee?
NESCAFÉ UK lists 50–90 mg caffeine per 2 g serving of Original or Gold. Other products, including decaf, need their own information. Adding water dilutes the same dose without removing its caffeine.
Café Bustelo gives approximately 70 mg caffeine for one cup of its US Espresso Instant Coffee, prepared with one heaping teaspoon and 177 ml (6 US fl oz) water or milk.
Choose decaf instant for a soluble coffee with less caffeine. Decaf still contains some caffeine, so use that product’s information rather than the regular Original/Gold range.
Regular instant can keep you awake: its caffeine can disrupt sleep. Sensitivity varies, and a coffee’s bitter taste does not measure its caffeine.
Why Do Calorie Figures Differ?
This plain 2 g recipe has an estimated 7 kcal with 0 g sugar, using a generic instant-coffee reference. Your jar's nutrition label may differ; milk and sweetener are extra.
Why the generic estimate and a product label can differ
The recipe's 7 kcal and 0 g total sugar estimates use USDA's generic regular instant-coffee powder record, USDA SR28 NDB 14214: 353 kcal and 0 g sugar per 100 g. For 2 g, the energy calculation is 353 × 2 ÷ 100 = 7.06 kcal. Water contributes no calories, and the plain recipe has 0 g added sugar.
NESCAFÉ UK describes its own black Original cup, prepared as directed, as around 1–2 kcal and gives an approximately 1.8 g usual dose. A generic database entry and a particular manufacturer's product are different references; use the actual label for your jar rather than averaging them. The caffeine and energy references on this page are deliberately identified separately.
The caffeine range comes from the named products’ manufacturer information.
What Changes in a 3-in-1 Sachet?
NESCAFÉ UK 3in1 lists 65 kcal and 8.4 g total sugar for one 16 g (0.56 oz) sachet prepared with 200 ml (6.8 US fl oz) water. The sachet combines coffee, sugar and creamer, so use the whole mix when calculating nutrition. Its label does not separate added sugar from total sugar. Check milk ingredients if avoiding dairy.
How Instant Coffee Is Made
Freeze-Dried vs. Spray-Dried Instant Coffee
Both methods begin with extracted coffee. Spray-drying removes water from droplets in hot air. Freeze-drying freezes the extract and removes its ice as vapor under reduced pressure. Both leave soluble coffee solids; neither means simply grinding roasted beans into a finer powder.
Compare freeze-dried and spray-dried products at the same weighed dose and water amount; blend and roast still matter.
Instant Coffee Troubleshooting
| Problem | Try this first |
|---|---|
| Bitter or heavy | Reduce the powder slightly, keeping the water fixed |
| Too weak | Confirm the dose and mug size before increasing the powder |
| Granules remain | Stir in a small hot-water portion first; check whether the product includes microground coffee |
| Gritty cup | Check that you used soluble coffee rather than ordinary grounds |
| Clumps in the jar | Use a clean, dry spoon and close the lid; keep it away from kettle steam |
| Stale flavor | Check the package date and storage directions; buy a size you can use reasonably quickly |
Nestlé Professional recommends a dry, airtight container in a cool, dark place for its instant coffee. Follow the package's storage instructions; adding milk creates a perishable prepared drink with different storage needs.
How Instant Coffee Became an Everyday Drink
Instant coffee has several early pioneers. In Invercargill, New Zealand, coffee merchant David Strang patented a soluble dry coffee powder in 1890. Heritage New Zealand describes it as possibly the first commercially available instant coffee: a practical way to turn boiling water into coffee without a brewer.
Nestlé’s 2013 account traces NESCAFÉ’s later breakthrough to a different problem: unsold coffee in Brazilian warehouses after the 1929 crash. Nestlé developed a soluble product and launched it in Switzerland on 1 April 1938. During the Second World War, much of its production supplied US troops. Portability helped give the jar a life far beyond the home kitchen.
