Howdy all! I have had my breville for about 6 months and have made some great coffees! I cleaned the machine tonight and now I can't get a good cup of coffee. I left my grind size the same, packed the same, HORRIBLE. Change grind size smaller, packed same, lighter, and harder, HORRIBLE! I went to a grind size 8 (usually a 6 is where its at) and nothing seems to work!
What else should I try?! I can't figure this out! My wife is asking why I have run the machine 10 times.

Sour coffee is usually a result of underextraction. This can be caused by a few things.
The extraction may also be happening too fast. Try for a finer grind and/or a heavier dosage. (ie. More coffee)
Of course, I do realize that you have a pressurized portafilter machine... so making the grind finer will only take you so far....
Another quick question.. how fresh is the coffee you are grinding? The beans shouldn't be any older than 15 days from the roast date. If you are using supermarket coffee with a "Best Before" date, all bets are off. The bag must have a "Roast Date" on it.
Coffee which is stale will extract too quickly. There's nothing you can do except throw the beans out and buy fresh at that point in time.
Garbage In, Garbage Out, for every step of the process. From Beans to grinder, grounds to machine, coffee to cup.
