I got myself a La Marzocco GS/3 Auto espresso machine an a Ceado E37S grinder for Christmas, and I it is way more of a machine than I thought it was and need help dialing in everything to pull consistent shots. I will take in any and all advice from people.
I picked up a BrewGlobal Brewista Smart Scale to help weigh everything, and have a bottomless portafilter with a double and triple basket. I am currently using Water Avenue Coffee - Brazil COCARIVE Natural Reserve, and have a bag of Stumptown - Hair Bender that was roasted a couple days ago as well.
So, what I do so far is that I am trying to get the somewhat default 18g dry / 30g liquid / 25 sec ratio that I keep seeing here. Now I am having hard time figuring how to nail that in :/ I don't understand why machine turns off at different times. I would have same grind and try to do same tamp, and with get different times from machine, once would be like 14 seconds and next would be like 38 sec.
I set my brewhead temp at 200.1 degrees right now, and played by lowering and raising temp by couple degrees also and quality did change by a lot just there alone. But going into settings I see prebrew options by the second, and not sure what best default to have it on right now.
Any advice is appreciated. I am located around PDX OR, so if anyone wants coffee, come by and help me tune this beast in
otherwise I will take any tips people throw at me. Bear in mind, I only had the machine for 6 days so far, so learning new things everyday!
