Hi,
New user of a Breville BES920 machine here.
Amateur home coffee maker.
I think we are getting what you'd call under extracted shots. Shots are somewhat sour to taste and we are getting well under 30ml volume for a single shot.
Image shows rubber band around glass where 30ml is.

Here's a video showing the extraction. This is pretty typical. There's only ever a stream of coffee at the end of the pre-infusion stage (pre-infusion settings are default. Pressure is good so I think my grind size is right. We have the matching grinder and its repeatedly putting out 16gm of coffee for single basket. We are using the single wall basket supplied with the machine. Everything else is stock.

Thanks in advance,
