Frequently Asked Questions
What ratio should I use?
Around 1:15 to 1:17 is common for pour-over and drip, which is the "water per coffee gram" field. 1:16 is a good starting point; lower numbers brew stronger.
How does the servings multiplier work?
It scales both coffee and water. 30 g of coffee at 1:16 with a multiplier of 2 gives 60 g of coffee and 960 g of water.
Is 960 g of water the same as 960 ml?
Very nearly, since 1 g of water is about 1 ml. Some water stays in the grounds, so your cup will be a little under the brew water weight.
