I'm a newbie in coffee extraction. Purchased the Breville DB 920 with Smart Grinder (Dynamic Duo model) about 7-8 months back. I usually have 1 cup/ day.
Last 2-3 months I am noticing drastic deterioration of my coffee extraction. I am getting lots of sediments / scum on my coffee that really tastes & looks
horrible.
Seeking advise from the experts on what I could be doing wrong..

I cant understand why I am having so much sediments / scum.
1) I clean my machine quite frequently using the cleaning tablets
2) I clean my portafilter and basket after use as I thought sediments trapped in baskets may be the cause of it.
3) I wipe the shower screen after every use.
4) The coffee that I use is medium roast, on subscription and is fresh.
5) I dose 20 gms on a VST 20gms basket and extract 20 gms in 25s approximately. The coffee as such tastes OK but initial sips are bitter because of the sediments. I have the same issue with Breville basket. Preinfusion 7s, Brew temp 92 degrees and Pressure 70%
6) My Smart Grinder setting is between 18-20. If I go lower then flow reduces.
7) Dose is controlled using Breville razor tool
8) Froth my milk using thermometer to 55 degrees. Milk is A2 full cream.
I still cant understand where is the sediments / scum coming from.
Any advise will be appreciated.
Thanks in advance

Sidd
