Back to the basics
I have tried a very large range of methods, machines and madness for my favorite drink.. I even managed to give up smoking but never quit the coffee....
In any event and probably because of optimizing my time, I stick to good ol instant coffee......
I have become almost alergic to Nespresso, more than 2 of them a day gives me "major dogs breath", my little Cafitiere Italien, handed down by Italien Mother-In-Law, has never seen daylight for years, the French coffee machine also hides in a cupboard , , unless some particular visitors arrive, but you can be sure that the instant coffee tin is always replenished with always a packet to spare.
As I write this I have some fresh French bread,"une flute tradition qui sort de la four", butter and jam and a large cup of instant in from of me.
If I was to vote for the best coffee ever though, it would probably be made with a a Robusto, Arabica mixture made in an Italian Cafitiere that is used daily..
Alternatively it would be a Turkish made coffee when it has been made with a little bit Cardammon. ( Never sure how to spell that spice)
PS Starbucks don't do coffee so I never bother with them either. Strangely enough though I don't care for most of the coffee served in the French or Swiss cafes/restaurantes either.
