16-parts water to 1-part coffee
Always start with good fresh-roasted coffee and filtered water; successful pour-over coffee brewing comes down to ratios. For pour-over coffee brewing, the water to coffee ratio of 16 parts (grams) water to 1 part (grams) coffee is a good place to start.
Note: To measure and brew pour-over coffee properly, you need a good scale. While most digital kitchen scales will do the trick, a dedicated pour-over coffee brewing digital scale with a built-in timer is worth the investment. More information and purchasing choices on digital scales can be found in this article.
Experiment on the ratios to adjust for your taste; try 15:1 or 17:1 to find the ratio the best suits your taste. Enjoy!
