A Beginner's Guide to Manual Coffee Brewing: Gear, Ratios, and How to Fix the Taste
Want to start brewing coffee at home? Learn the basic gear, a safe starting ratio, and how to adjust when your coffee tastes too sour or too bitter.

The basic gear you actually need
Manual brewing does not require a lot of equipment. To start, these five items are enough, and you can add more once you are comfortable.
- A dripper (for example a cone-shaped V60 style) and its paper filters.
- A small digital scale so coffee and water amounts stay consistent.
- A kettle, ideally with a gooseneck spout for a slow, controlled pour.
- A cup or server to catch the brew.
- Coffee beans, and ideally your own grinder.
Coffee ground just before brewing is usually more aromatic than pre-ground coffee that has been stored for a long time. If you have no grinder yet, ask the shop to grind for your brewing method.

An easy starting ratio
Start with roughly 1 part coffee to 15 to 17 parts water by weight. For example, 15 grams of coffee with about 250 grams of water. Then adjust to your taste rather than to the numbers.
Weighing is more accurate than using a spoon, because a spoonful of coffee can weigh different amounts depending on the bean and grind.

A simple V60 method
Water temperature commonly ranges from 90 to 96 degrees Celsius. Darker roasts often taste good with slightly cooler water.
- Rinse the paper filter with hot water, then discard the water to reduce any paper taste.
- Add the ground coffee, level the surface, and tare the scale.
- Pour a little water (about twice the weight of the coffee) to wet all the grounds, then wait 30 to 45 seconds. This step is called the bloom.
- Pour the remaining water slowly in a circular motion until you reach the planned total.
- Wait for the water to finish draining. Total brew time is usually around 2.5 to 3.5 minutes.

Grind size shapes the flavor
For a cone dripper, a medium to slightly fine grind usually works, roughly like table salt. A finer grind slows the flow and extracts more flavor; a coarser grind speeds up the flow and gives a lighter result.

Not quite right? Change one thing
If the coffee tastes too sour or thin, it is a common sign of under-extraction. Try grinding a little finer, using slightly hotter water, or extending the brew time.
If it tastes too bitter or dry, it may be over-extracted. Try grinding a little coarser, lowering the water temperature, or shortening the brew time.
Change only one variable at a time and write down the result. This helps you find the settings that suit your beans and equipment faster.
Checklist before buying gear
Start with simple equipment and upgrade gradually. You do not need expensive gear to make a good cup at home.
- Match the dripper size to filters that are easy to buy.
- Choose a scale with a tare function and, if possible, 0.1 gram precision.
- Make sure the kettle is comfortable to hold and the pour is controllable.
- For a manual grinder, check that the grind is adjustable and easy to clean.
- Read reviews from buyers who brew in a similar way to you.
Frequently asked questions
Do I have to use my own grinder?
No. A grinder helps preserve aroma, but you can ask the shop to grind to match your brewer while you start.
How long should coffee brew?
For a V60, usually around 2.5 to 3.5 minutes. Treat it as a starting point; taste and the type of coffee can shift it.
Why does my coffee taste sour?
Often it is under-extracted. Try a finer grind, slightly hotter water, or a slightly longer brew time.
