Hello to everyone,today im turely happy after a long battle with my Expobar and allot of reading around the forums i came up with this i would like to know if i am wrong in any way
i adjusted my pump pressure to 9bar i did that with a gauge attachment to my Portafilter my steam pressure is around 1.1 ,I am using 14.2 grams of coffee i am getting around a shot and a half in 30 sec i do home roast i used new classic espresso from sweet maria to a full city roast and i was shocked with the results my espresso this morning was just fantastic i use to use 1 teaspoon of sugar but today there was no need the flavors where amazing and i did not think i would get so excited abut this,i do start the timer as soon as i hit the brew button but not sure if i should start the timer with the first drop of espresso just because the office control takes about 10 sec for the first drop,Before my pump pressure was at 10bar and my espresso was bitter,Just want to know if i made the right changes here if i go by taste i say i did but i want to ask the experts. thank you joe...
PS i belly tamp now where be4 i would apply the 35 - 40 pounds of pressure, i grind at number 4 i use to use grind at 5 and a harder tamp

I start "the clock" at the start of the cycle, but I don't think it matters much, just be consistent and adjust for taste. Tamping is not a huge thing, the goal is to compress the grounds to present an even restance to water flow so you don't get channeling. After that has been done, there is no more value in tamping harder.
