1. Use 92 - 96 C Water
Avoid using water right off the boil as it will scald the brew and make it taste bitter. Instead, allow boiled water to cool for a minute or so before using. The best temperature for coffee is between 92 C and 96 C.
2. Get The Ratio Right
The ideal ratio of coffee to water is one heaped teaspoon of instant coffee powder to 150 ml water.
3. Go For Milder Blend
Like your coffee less intense? Buy a mild blend, rather than using less of a dark roasted variety, as that just produces coffee with a thin, watery taste. Using a milder blend means the flavour and aroma is retained, but the taste is lighter and not so heavy.
4. Keep It Sealed
Don’t let an opened jar of instant coffee hang around in the cupboard or on the pantry table for too long. Its taste starts to deteriorate once it’s exposed to air. The flavour loss is minimal over three to four weeks, but any longer and you’ll notice a real difference.
5. Never Reheat Coffee
Don’t be tempted to reheat your coffee. If it goes cold, throw it away. Reheating it in the microwave results in a stale-tasting cup. You will be better off preparing a fresh cup instead.
