How to Brew Coffee Beans at Home (No Fancy Gear Needed)
A simple guide to brewing roasted coffee beans at home: the golden ratio, grind sizes, water temperature and four easy methods — French press, pour-over, moka pot and South Indian filter.
You don't need a café counter to make great coffee from whole beans. You need four things: the right ratio, the right grind, hot (not boiling) water, and a few minutes.
The golden ratio
Start with 15 g of coffee for 250 ml of water — roughly 1:16. Too strong? Add water or use less coffee next time. Too weak? Do the opposite. There's no wrong answer; think beyond the rules and find yours.
Water temperature
Aim for 92–96 °C. Easiest way: boil the kettle, then let it sit for 30–60 seconds.
Grind size cheat sheet
| Method | Grind | Brew time |
|---|---|---|
| French press | Coarse (like sea salt) | 4 minutes |
| Pour-over | Medium (like sand) | 2.5–3.5 minutes |
| Moka pot | Fine-medium | Until it gurgles |
| South Indian filter | Fine | 10–15 minutes to drip |
Grind just before brewing — ground coffee loses aroma fast.
Method 1: French press
- Add 15 g coarse coffee per 250 ml water.
- Pour hot water, stir gently.
- Lid on, wait 4 minutes.
- Press slowly and pour immediately.
Best with: RAWNG Monsoon or RAWNG Dark for a heavy, rich cup.
Method 2: Pour-over
- Rinse the paper filter with hot water.
- Add medium-ground coffee and pour just enough water to wet it. Wait 30 seconds.
- Pour the rest slowly in circles over 2–3 minutes.
Best with: RAWNG Peaberry to taste its sweetness and brightness.
Method 3: Moka pot
- Fill the base with hot water up to the valve.
- Fill the basket with fine-medium coffee — level it, don't press.
- Heat on medium-low and take it off as soon as it starts to gurgle.
Best with: RAWNG Punch — strong and bold, great with or without milk.
Method 4: South Indian filter
- Add 2–3 tablespoons of fine coffee to the top chamber and press lightly with the plunger.
- Pour hot water to the top, close and let it drip (10–15 minutes).
- Mix the decoction with hot frothy milk and sugar to taste.
Best with: RAWNG Classic — Robusta-led body that stands up to milk.
Storing your beans

Frequently asked questions
How much coffee should I use per cup?
A reliable starting point is 15 g of coffee (about 2 heaped tablespoons of whole beans) for 250 ml of water. Use more for a stronger cup, less for a lighter one.
Can I brew coffee beans without a grinder?
You'll need to grind the beans before brewing. A simple manual burr grinder is affordable and gives an even grind; blade grinders work in a pinch if you pulse in short bursts.
What water temperature is best for coffee?
Around 92–96 °C — boil the kettle and let it rest for 30–60 seconds. Boiling water can make coffee taste harsh.
How should I store coffee beans?
In an airtight container or the resealed pouch, in a cool, dark, dry place. Avoid the fridge, where moisture and odours can affect flavour.
