The “Coffee Golden Ratio” of coffee-to-water in general is, every six-ounce water needs one to two tablespoon of coffee depends on the strength for brewing coffee.
To be exact, it is believed, 1 to 17.42 ratio of coffee to water is the coffee golden ratio. On that basis, one tablespoon of coffee is the best coffee grounds to water ratio for one cup of coffee.
Coffee has different varieties. So, the golden ratio is not actually “perfect” for all types of brewing methods.
Simply, you cannot use the same ratio of coffee grounds to water while making espresso or cold brew. Right?
Also, people have different tastes for themselves based on personal taste, strength, milk and sugar, and others.
So, here we have tried to simplify the best coffee grounds to water ratio for different types of coffee.
Best coffee Grounds to Water Ratio For Different Coffee Types

Then again, for strong taste, the amount of coffee would be 27.27 g.
Best French press coffee makers bring out the best result. Let’s have a look at the gram of coffee to amount of water.

The core ingredient of coffee is the bean (Obviously 😊).
The bean should be great to make a good cup of coffee. You do not need high pricey beans to make good coffee. Despite that, you need to focus on some points of bean –
The first quality you need to ensure is the freshness of the bean. You can always have fresh beans if you do not stock them. Buy in small amounts and regularly. But if you prefer to or need to buy a considerable amount of beans at one time, you should know the best way to preserve coffee beans.
We usually buy roasted coffee beans. Or can home roast them. You need to have an eye on the roast type. Roast types influence flavors.
Variation of coffee needs different types of grind size. For instance, French presses need coarse coffee grounds whereas espresso needs finest grounds.
It is very important to use best possible equipment for everything.
If you prefer buying whole beans and grind them yourself, you should use proper grinder. As I mentioned earlier, different types of coffee required different types of coffee grounds, you need respective grind size.
Some people like manual coffee grinder and some like automated.

Yeah. Water quality matters!!
People usually do not pay attention on water but its high time you changed your view.
If the water you using is not up to the mark, you may not have a good coffee even after doing everything right.
You may use bottled water or filtered water if your tap water has distinctive smell or bitter taste.
For some types of coffee, you need to add hot water manually. For that, should use best water kettle for coffee.
This is an optional equipment. You may use spoon to measure amount of coffee.
But it’s worthy to be perfect. You can buy weight machines to measure your coffee amount.
During the brewing process, you need to be alert on extraction. We have spoken briefly of brewing time but not at the same time though.
Brewing time can be short, like brewing time for espresso is 20-30 seconds. On the other hand, the brewing time of cold brew is a minimum of 12 hours.
But you have to be very very alert on over-extraction and under extraction. Or, it will mess up with your taste.
You need to focus on water temperature while making coffee. Overheat or under heat may ruin your coffee.
For all the coffees served hot, usually, the range of 195°F – 205°F is ideal for them. But you need to be specific sometimes.
Like, 200°F is the best water temperature for French press coffee.
We consume coffee very frequently. Commonly we overlook the small miscalculations we make on making coffee.
But, sometimes, maybe once in a while, we like to taste the ‘Perfect’ coffee. Maybe the weather is too lovely, maybe the mood is too good or may the situation demand.
That time, we need to focus on every detail like grind size, coffee to water ratio, measurement, water temperature, and others.
To conclude, while we try to maintain the best coffee grounds to water ratio hardly, we sometimes forget about other things. You need to remember only the best coffee to water ratio cannot server you the perfect cup of coffee. You have to consider the other factors also.
Enjoy Your Coffee!!
