I'm staying at a friends house this week and trying out their Breville Express. By chance I tried out a Blue Bottle expresso roast and it was a consciousness altering experience! I've tried many home expresso machines over the past few decades and this is by far the most awesome machine I have used. I'm working my way through a bag of Philz medium roast right now. Quite good but not as mind boggling as the Blue Bottle.
