I’m after some advise on what I should do next. I purchased a Sage Barista express a little over 6 weeks ago and after watching endless YouTube Videos and reading numerous blogs I believe I have got a grasp of the basics. However, I appear to be hitting the same consistent problem, my coffee is extracting in around 13-15seconds, which form what I read is too fast. For clarity, this is 13-15 seconds from the point that I see the first drip of coffee appear from the portafilter, so total time from pressing the double shot button is around 20-23 seconds.
So, here is where I am at so far… I grind exactly 18.5g of coffee on grind size 2 (I’m reluctant to go to grind size 1 as it leave me nowhere else to go from there). I grind on setting 2 as mentioned, which means my pressure gauge sits at the top end of the expresso scale, around o'clock on a clock face. I am tampering using the supplied temper tool and I try by best to evenly spread my grind out first. The 18.5g means that when I use the supplied razor I have zero wastage and nearly all the time it’s at the level where the razor would start to shave off excess. I have programmed the machine to extract 36g of coffee (2:1). My beans are from Pact, so have been freshly roasted within the last 7 days and I have had possession of them for under a week. So with all the above info, can anyone suggest what I need to get my extraction time to the more desirable 20-30seconds? Equally please tell me if I am trying to achieve the impossible and I should just continue as I am!! Thanks in advance.
