Two things.
First in another tip to keep up with machine maintenance. Earlier I stated I did a backflush once a tank. When I did my first clean with cafiza and removing the group head, noted coffee oils built up on the back of it. Since then I have been doing a back flush after each session per breville's recommendation. Went to remove the group head one month later and it was still pretty much clean with just some grounds to clean out. Guess to show the back flush after each session actually matters! I still soaked everything in cafiza to make it extra clean.
Second in another resupply, the roaster sent in a sample of their dark roast blend. Made up of coffees from Mexico, Brazil, Honduras, and Sumatra. Sipping on that right now and it is very good!
