My process is that I fill the filter halfway with coffee, fill the jar with cold water, wait 24-48 hours, then refrigerate. That's it.
The entire process is super simple. I don't need to worry about presses, disposable filters, machines, etc. I just need to rinse the filter and clean the jars occasionally.
It's super easy to clean, makes a week's worth (at least for me), lets you serve directly from it, and I think it looks really good.
Whatever you do, make sure you use coarse-ground beans. They extract so much more flavor than medium or fine, in my experience.
