Baratza Sette 270Wi


The brand new 270Wi learns from the 270W and goes further to make your coffee grinding even more accurate.

Using scale manufacturer Acaia technology that process is a lot quicker than previous.

The key features of the Acai driven 270Wi are:

1. The Wi processor contains a smoothing algorithm that helps the grinder focus on the important information: ground coffee falling into your portafilter. This smoothing algorithm allows the grinder to better ignore irrelevant spikes in load cell information. For example, bumping into the countertop can create a vibration which the Wi ignores.

2. The Wi is intelligent. If, for example, the grinder’s target weight is 20g but only 19.6g are produced, the Wi will self-adjust. On the next grind, it will stop the motor just a little later. This might result in a slight overdose, but not to worry; the Wi keeps learning and within a few grinds will self-adjust so that it repeatedly doses within a few tenths of a gram!

This means awesome accuracy.

3. Improved user interface

  1. Burst Mode: A common frustrating experience on the 270W is under-dosing. If a 270W stops short of its target dose, the user is unable to “top off” the grind without zeroing out weight readings. If the Wi stops early, but within 5g of the target, it will enter Burst Mode. When in this mode, each press of the START button runs the motor for 0.1 seconds. This function can be used indefinitely until the portafilter is removed or the STOP button is pressed. Burst Mode allows the home barista to grind more coffee incrementally, ‘topping off’ from 16-19.8g up to 20g.
  2. Under-dosing: If the Wi stops early and is more than 5g from the target, it will switch to Pause Mode. From here, simply pressing START again will continue grinding towards the target weight.

Fantastic Grinder

I've been using this Grinder for espresso and pour over and I couldn't be happier with the grind consistency and dosing. It also looks fantastic on the counter.

Update after a few weeks

We have now got to appreciate the difference in taste from the Baratza grind! Forgot to mention how little static is created - the coffee ends up in the basket, not the bench. Still totally impressed with the consistency of the grind and dosing.

Flawed but essentially excellent

It's early days but the 270wi has a lot in its favour. The vertical path is a huge improvement on my elderly Rancillio Rocky, the accuracy of the dosing is phenomenal and it grinds 18g in almost no time. The machine is also very neat and compact but remarkably light - so much so that an over-enthusiastic push of the 'on button' can send it scuttling! The quality of the grind seems faultless, so far, and eliminates 'fines' as far as I can tell. The result is a very clean brew (espresso) with a fabulous lasting crema and very attractive mouth-feel. Unfortunately it is showing up things in our long-time favourite bean blend that we don't much like, so we will need to experiment again with other beans!

On the negative side I am concerned that such a light motor and mechanism will stand moderate domestic use for many years. Time will tell. Annoyingly, the portafilter hook is pretty useless with the Expobar Leva 4 portafilter and VST basket- its backstop is in the wrong place and the arms of the 'hook' tend not to hold the thing in place - result is some of the grind falling down the back of the portafilter and sometimes the pf dropping off mid-grind. I use two pfs - the standard 2-cup one with an 18g VST basket and a naked one with a 15g VST basket but these are different depths, necessitating twisting of the rubber cushions on the arms supporting the pf - I wonder how long before these start turning of their own volition!

In conclusion, the grind quality and weighing functions are superb - so far, but some of the practicalities are a pain. There are far more expensive 'domestic' grinders out there but this is still quite a bit to pay.

Fantastic grinder

Whilst the 270W had some issues this grinder is amazing. Just plug in your dose needed and grind away. Much more accurate. I typically get to within in 0.1-0.3g og required dose. Theres an app to connect to Acaia scales and brew bar app. But I just love the ease and repeatability of this grinder.
Its been worth the wait!!
