The ratio for pour-over coffee, which refers to the proportion of coffee grounds to water, affects the coffee's "strength." For example, using 20 grams of coffee grounds and 300 grams of water creates a coffee-to-water ratio of 1:15. Is there a definitive "golden ratio" for a great-tasting brew? Actually, there isn't a set standard because everyone has different preferences when it comes to coffee strength. Your golden ratio is the one that suits your desired strength. That said, many people use a coffee-to-water ratio of 1:15.



Comparing coffee-to-water ratios of 1:12 and 1:15, a 1:12 ratio will yield a stronger brew. For example, using 20g of coffee grounds and 240g of water will result in a stronger cup compared to using 300g of water. As the coffee-to-water ratio increases, the brew becomes milder, allowing you to adjust it according to your taste preference.

Taking the recently favored coffee bean of Justin as an example, the "Ethiopia Geisha Village Shewaguba Red Label Washed" is known for its floral aroma with hints of cherry and passion fruit, a sweet and bright finish with a hint of red tea and citrus notes.

Regarding water measurement, there are two common methods. One calculates based on the "amount of water poured," and the other calculates based on the "amount of coffee liquid that flows into the lower vessel." For example, for a 1:15 ratio, where 300g of water is poured over 20g of coffee grounds, the final coffee liquid amount won't be exactly 300g because some water is absorbed by the coffee grounds. You'd typically obtain around 260g of coffee liquid, so to get 300g of coffee liquid, you'd need to pour approximately 340g of water. Both methods are used, so when discussing ratios, it's a good idea to confirm which version is being referred to.



As an extra note, there's a coffee-to-water ratio of 1:13 that was unintentionally used, somewhere between 1:12 and 1:15. It resulted from Justin mistakenly adding 15g of water when brewing using a 1:12 ratio. This ratio yielded a cup that was somewhere in between, with a full flavor, strong finish, moderate acidity, noticeable sweetness, and good body. It's fascinating how just a 1g adjustment to the ratio can result in a unique flavor.



After trying these various coffee-to-water ratios, it seems that Justin would likely enjoy a 1:12 ratio on his own. What's your preferred coffee-to-water ratio? Find your perfect ratio.
