I know more than 20 different ways of making coffee.
Here is the best coffee brewing method I've come up with.
First, I get some CLEAN water, and I boil it in an unfinished metal or ceramic-finished metal pot. I use a regular pot so that I can see inside. I also like to let a little bit of the water evaporate...
While it's getting ready, I get the best and freshest coffee grounds I can muster, it's better if I can grind them on the spot, but that's not always available.
I put the coffee grounds, as much as I think is necessary, into a glass or ceramic bowl, and pour the boiling water over them. I optionally cover and/or stir and let steep.
After about 5-15 minutes, I pour the coffee into another glass or ceramic bowl, letting the grounds stay at the bottom of the first bowl.
The coffee is now ready for drinking. To keep it warm, I cover it and leave it in the oven for insulation, or use an electric plate. It usually doesn't last long. It's good cold too.
The second best method I know is cold-brewing in a similar fashion, takes a number of hours I haven't tracked yet.
If anyone is interested in learning why this method is better than all the others, please reply with the method you think is better and I will explain why you're wrong. :^)
Edit: The method in the video is quite good, and my only complaint is that it uses disposable filters, which leads to unnecessary materials harvesting, human labor, biome squeeze, diesel use, waste output, and other artifacts of production.
