Thank you, David. I very much enjoyed this, especially as a committed coffee enthusiast. In addition to the varieties, there is the "white wine- red wine" equivalent in coffee, arabica and the much neglected but often superior robusta., introducing another set of important variables.. There are many songs about wine; coffee seems less often to be the subject of the muse.The Prairie Home Companion found a way to recognize coffee with this jingle: https://www.youtube.com/watch?v=agusq6xfefI "Smells so lovely when you pour it You will want to drink a quar’t Of coffee. It’s delicious all alone, it’s Also good with doughnuts. Black coffee Coffee stimulates your urges It is served in Lutheran churches Keeps the Swedes and the Germans Awake through the sermons Have a pot of it today I’m sure you’ll say it’s awfully Good coffee."
