I am huge coffee fan and developed a taste for coffee when I was 5 years old. I grew up in a south-indian family where morning coffee was a ritual. When I used to live in US and Germany, my single-origin staples were Ethiopian Yiragacheffe (Dark roast, medium acidity, nutty flavor), Nicaraguan ( Dark, intense chocolate), Hawaiian Kona (Medium roast, floral and rich). I tried roasting beans but getting it right was tricky. So just stuck to grinding and brewing. My favorite method is the Moka pot to extract the maximum flavors while avoiding the bitterness/metallic aftertaste. I don't like instant coffee or chicory anymore though I used to have it all the time when I was younger.
After I moved back to Bangalore, I tried the various coffee brands that have mushroomed here - Blue Tokai, TGL, Rage, Slay, Third Wave, Korebi, Corridor 7, Dope etc. For those of you who use Cred app, check out the coffee store that curates and sells these brands. With the exception of Third Wave, and Blue Tokai to some extent, most of these brands are inconsistent and I don't think are even single-origin.
I have zeroed in on coffee from a small organic farm near Salem in Tamilnadu called Dragonfly Farms, run by an Austrian restauranteur in Bangalore, who really knows his coffee. After having tried over 30+ varieties from all over South India, I believe this is one of the best. It is available for delivery only in Bangalore as of now. They have only one varietal - 100% Arabica USDA organic certified, small-batch dark roasted on the day of the order. Pure Bliss in a cup! Try it.
