Off the back of yours and the child comments, I tried a swiss water decaf for the first time (beans) and it tastes amazing - I wouldn’t know it’s not regular coffee.

For reference for anyone interested, I used a Mochamaster filter brewer with these beans (which I freshly grind - which probably helps the taste too):

Lavazza Decaffeinated, 100% Arabica Medium Roast

This is exciting to me as I can finally wean myself off caffeine while keeping my {difficult to kick} coffee habit!
