I recently roasted a blend of Columbian Bauche, Kuda Mas and MM. My wife is ecstatic about this in milk and I've had a glowing compliment from a friend whom I supply with beans. She particularly loves the crema (that'll be the MM). I'm not as fussed as espresso. It's fine, but lacks the body/flavour I'm after, but I suspect I could get better out of it by dropping the temp on the Bezzera's PID.
