The standard brew time is about 4 minutes. But normally, it’s not enough for most people, especially when you use a coarser grind. The steeping time is closely relevant to the ground coffee size. 6-10 minutes will be just great if you use the medium or medium-coarse. Using the technique mentioned above, it can take 10 minutes or more. When to decant your coffee depends on how much sediment you want in your final cup. The longer you wait before decanting, the less sediment you'll have in your final cup. It's not going to be over-extracted in a few more minutes since when the coffee grounds are at the bottom, the extract rate will slow down a lot. But you don’t want to leave the coffee with the grounds for more than an hour.
