I am new to BH and purchased my Breville Barista Express roughly a month ago. I wanted to reach out to see if I could potentially get some assistance with my extraction. Per discussion with my local roaster, I’m dosing 20g of coffee, with hopes of getting 40g of espresso out of my 54mm portafilter. That being said, I am getting roughly 35g with each shot and I’m not sure what to do. I thought about grinding a little coarser, but feel that my portafilter is already about as full as it can be without causing issues. The BBE is difficult to time, as it has a pre-infusion cycle that can be difficult to gauge; it warms up for ~8 seconds, and then espresso comes out, all in all my infusion time is roughly 35-40 seconds, which I believe is too long. Can anybody please offer some advice on how to get a more accurate extraction? A few notes below:
-I am using freshly roasted beans (roasted 1/30)
-I feel like I’m tamping adequately
-I’m using filtered water.
