Both! It really depends on how into brewing the perfect cup of jow you are; our ground coffee is perfect (we think so at least), on its own, and its flavor profile and strength are apparent through any extraction technique. However, if you’re a coffee nerd (like everyone at Killa Caffeine is), then you may want to purchase our high caffeine coffee beans to grind them to whatever extraction method, flavor profile, etc. that you like the best.
