I like a small french press that makes one cup worth at a time. I occasionally splurge and get some Vietnamese robusta coffee and that’s really special. My everyday coffee preference is cuban style Cafe Bustelo.
Water quality makes a big difference in coffee flavor to me. The tap water here has a ton of mineral content. So, I have a softener and reverse osmosis water purification system.
Hotels are hard places to get a good cup of coffee. So I travel with an AeroPress french press.
