We here at Roaster Central love a good coffee, but repeating that coffee, and trying different brew methods, has always been a challenge. We found that if you standardize your manual brewing recipe, the results are more consistent, and it's so much easier to taste the difference in brew methods when using the same formula.
The other slightly different aspect is how we typically define our recipe. Instead of doing the math to find a ratio, we find it's much easier to divide based on the number of cups! Without further ado, here it is!
This recipe will make 4 x 250ml cups of brewed coffee. In imperial, that's 4 8.5 fluid ounce (oz.) cups. or about 50 teaspoons, or about 0.000327 cubic yards. You get the idea.
Only want a single cup? No problem: All the brew guides are based on making a single cup. As such, the recipe is divided by 4. 15g coffee to 250ml of water.
Still looking for a brew ratio? We get it; it's approximately 1:16.7
All of that said, coffee is a personal endeavor, so we recommend adjusting the recipe if it's not to your taste!
