The main thing for me is a french press. I like how it preserves the oils from the coffee beans that would otherwise get removed by a paper-based filter. I try to ensure the coffee grounds are coarse so they will not pass through the metal filter. The coffee I'll have it black if it accompanies a meal, otherwise with some plain cream to serve as a vehicle for a fat-soluble vitamin D3 supplement. The french press is great for making cold-brew coffee too - just leave it overnight and filter in the morning.
