I have tried many brands. We have 2 automatic coffee makes and a Nespresso machine. Both automatics are made by Capresso, I believe a Swiss brand. One is for regular coffee the other for espresso. For regular coffee we buy decaf whole bean Cubano roast from Costco.
For espresso we get espresso roast from Wegmans.
Both machines store and grind the right amount of brand for selected amount of coffee.
My wife only drinks decaf, because of a cardiac problem, I love my espresso. In the morning i drink a cup of decaf with a double espresso mixed in.
