Why drinking coffee in Iran has become so complicated (adelbordbari.github.io)
It all started with a sarcastic jab in a chat: “You shouldn’t be more Catholic than the Pope. You go to order a coffee, and the guy’s like, ‘From Kenyan farms or Brazil?’ It’s like going to Italy for ghormeh sabzi, and they ask if you want the herbs from Bostanabad or Tuyserkan. Come on—just give us an espresso so we can move on with our lives :))”

Fridge or Freezer: Where Should You Store Your Coffee? (wordpress.com)
The debate on coffee storage resurfaces from time to time, although, much like Galileo’s discovery, few skeptics remain. Yes, the Earth orbits the Sun, and coffee is best stored in the freezer, in whole beans and vacuum-sealed. If you have a freezer at -70°C, you could even enjoy it a century from now.

Coffee Plants of the World (sca.coffee)
Coffea arabica, which is indigenous to Ethiopia and some neighboring lands, first was transported out of its homeland into neighboring Yemen. From Yemen, coffee was transported around the world. The coffees that we call typicas today originated from plants that left Yemen and were taken to Java and outlying Islands, possibly by the Dutch, possibly with some transport by the mythical monk Baba Budan. The coffees we call Bourbon today stem from plants transported to Ile Bourbon with the French.

You are how you resist (medium.com)
If you live in Amsterdam, you’ve probably seen a coffee chain called Cafecito. Decent coffee, minimalist typographic logo, snowy-white walls, clean geometry of interior objects, perfectly lined up branded merchandise on wooden shelves. I hate it. It is less authentic than Starbucks on a train station. Cafecito is so outstandingly unremarkable that its facelessness feels to me like a personal insult.
