We’ve developed a simple 5-step tool that helps you calculate the right coffee-to-water ratio for 8 popular brewing methods.
Step 1: Start by selecting your brewing method (such as pour-over, AeroPress, etc.) and your preferred drink size. For this, begin by selecting the size in “cups,” then note the equivalent measurements in ounces, grams, or milliliters of water.
Step 2: Pick your desired coffee strength, ranging from mild to robust. The mild brew options for auto drip, pour-over, Chemex, and AeroPress are based on the SCA Golden Cup Standard For other brewing methods, our recommendations are based on experience and can serve as a helpful starting point.
Note:*All brewing ratios use grams, so 1 gram of coffee corresponds to "x" grams of water.
Step 3: Identify the grind size appropriate for your brew method. These suggestions are a general guide for your grinder settings, but your total brew time may affect your final choice.
Step 4: Choose the ideal brew length, with shorter times producing a milder cup, while longer brew times lead to a stronger, bolder flavor. Factors such as grind size, coffee type, and brewing method can significantly affect the brewing duration. You may need to experiment to find the ideal time, as different coffees can respond differently.
Step 5: Capture your recipe and give it a try! And Enjoy.
I've been experimenting with different coffee brewing methods at home, and I've found some great coffee-to-water ratios that work perfectly depending on the strength of coffee you're after. Let me walk you through the methods and coffee to water ratios I recommend for various brewing techniques. Plus, I've added a couple more options for you to try out!
For pour-over, the coffee-to-water ratios can be adjusted based on how strong or mild you want your coffee:
These coffee-to-water ratios are perfect for achieving the ideal cup depending on your preference.
With a French Press, you have a bit more control over the brew's flavor. Here’s what I recommend:
Using these coffee-to-water ratios ensures you get the right balance of strength and flavor from your French Press.
The Chemex is another popular brewing method that delivers a smooth cup of coffee. Here are the ideal coffee-to-water ratios:

Now it’s your turn to test these at home and find what works for you. Enjoy your coffee brewing adventures!
I've gathered some of the most important basics when it comes to coffee brewing. Whether you're a beginner or someone looking to refine your process, these tips and insights will help you brew the perfect cup.
Coffee brewing ratios refer to the proportion of coffee grounds to water used in any brewing method. This ratio can make or break your cup of coffee. The Specialty Coffee Association recommends a standard coffee-to-water ratio of 1:18 for most brewing methods, including pour-over, French Press, Chemex, and autodrip. This means 1 gram of coffee per 18 grams of water. Experimenting with this ratio can give you different strengths depending on your taste preferences.
The optimal temperature for brewing coffee typically falls between 197 – 205 degrees Fahrenheit, depending on the method and roast of the coffee. For best results, let boiling water sit for about 30 seconds to 1 minute before brewing to reach this ideal temperature. Too hot, and the coffee may taste burnt and bitter; too cold, and it will come out flat and under-extracted. Temperature is a key factor in coffee brewing to get the right flavor profile.
Light roasts benefit from a higher brewing temperature, ranging from 203 – 212 degrees Fahrenheit. These higher temperatures prevent sourness and bring out the delicate acidity of lightly roasted beans, giving you a bright, balanced cup of coffee.
For medium roasts, aim for a brewing temperature of 194 – 203 degrees Fahrenheit. Let boiling water sit for about 30 seconds before brewing. This temperature ensures a well-balanced cup, enhancing the roast's natural sweetness while avoiding over-extraction.
Dark roasts benefit from a slightly cooler brewing temperature, around 185 – 195 degrees Fahrenheit. Letting the water cool for about a minute before brewing will help reduce bitterness and highlight the natural sweetness in darker beans.
To brew the perfect cup, focus on three key factors: time, temperature, and brew ratio:
By controlling these variables, you can consistently make a delicious cup of coffee. Keep testing, note the results, and tweak one factor at a time to perfect your brewing process.
If your coffee is bitter, here’s how to fix it:
Here are tips for brewing strong coffee without bitterness:
Follow these 6 tips to improve your coffee brewing:
Coffee tastes best between 7-30 days after roasting. Always grind your beans fresh for each brew.
A quality burr grinder can make all the difference in coffee brewing, as it ensures consistent grind size, which is crucial for extraction.
Timing is critical for consistency. Use a timer to ensure your coffee doesn't under or over-extract.
Always use a scale to measure your coffee and water, as volume measurements like scoops can lead to inconsistent brews.
Water makes up 99% of your coffee, so ensure it's good quality. Filtered water will help bring out the best flavors from your beans.
Coffee oils build up over time and can make your brew taste stale or bitter. Regularly clean your grinder, brewer, and any other coffee-making tools to ensure a fresh taste.
These tips will help you get the most out of your coffee brewing experience, whether you're using a pour-over, French Press, or another method.
