I was never a coffee drinker at all until I spent a month in Kenya 6 years ago helping a startup get off the ground (ex CTO/CEO lived in Nairobi at the time). I tried the local coffee as was customary (when in Rome...) and because the Kenyans were SO passionate about their local coffee.
I was floored. I got completely hooked, and to this day have not found quality Kenyan coffee here in the USA. The coffee in Kenya is incredible, puts the crap Americans pay $$$ for at Starbucks to absolute shame.
A high quality roast, a decent grinder and a pour-over will make home brewed coffee that is not even recognizable next to the swill they sell at Starbucks. To be fair though, at Starbucks' scale it neigh impossible to produce consistent flavor with the quality of curated small batch coffee.
