Baratza Sette 270Wi notes

minimum dose size?

I use the Hario switch to brew my coffee and am trying to reduce my caffeine consumption. Hence I would like to brew smaller cups of coffee. I am currently using 10g of coffee with 160g of water. (1:16 Ratio) I am wondering if there is a minimum amount of coffee...

Baratza Sette 270Wi notes

We just retired our 12-year-old Rancilio Rocky grinder, upgraded to the Sette 270i for finer control of grind and for the Wi weight-dispensing feature. The Sette has a load cell that weighs the portafilter, and then operates the grinder to dispense a preset weight in grams. It's awesome. There is very little coffee left in the machine, because the coffee flow is pretty straight through. I think it is going to be superior to the Rocky, which collected a fair amount coffee debris and needed a labor-intensive cleaning every two to three months to keep running.

The Sette self trains to decide when to cut the drive motor off. That's required because the motor costs and coffee keeps dropping for a short time after the motor is switched off. It takes a couple cycles to hit the preset weight accurately, and on the training cycles it may stop a couple of times and need to be restarted to get to the desired output. Suddenly our grinder seemed to be in continuous self-train mode, though. Would never get to the desired weight. I'm shaking my head, and even read through the manual. Could not figure out what was going on.

After a while I noticed that my wife put a nice plastic tray underneath the grinder to collect debris. Hmmm. I removed the plastic tray and set the grinder on the solid countertop. Then it worked flawlessly. Seems that if the grinder is vibrating because it is on a soft base, that interferes with the weight measurement. I suspect that this will apply to any weight-based espresso grinder. They probably all need solid foundations.
