You’re going to want to use either filtered or bottled water. That’s not such a concern here in the Middle East where pretty much all water is bottled, but do not use distilled water. Distilled water doesn’t have any of the additional minerals which help with extraction.
There are a few different types of filters that are used in most coffee makers so you’ll need to prepare your filter as advised by your manufacturer. If your coffee maker uses a cone-shaped filter, fold the crimped edges in opposite directions and place it into your filter basket. If you’re using a wavy, flat-bottomed filter, you can drop it in as is. If your filter has stainless steel, reusable filters then no need to prepare anything – you’re good to go!
Add your coffee grounds to the filter and place the basket back inside the machine. Turn on the machine on default settings and wait for the brew cycle to complete. Brewing time is roughly 3 to 5 minutes on most machines.
