hi Jacky, i actually don't have your problem, same bag of beans, always consistent if i use same weight and same coarse level. some mistake can easily be spotted. Thinking maybe ask them in person later this week when buying beans. Not sure if they are too busy to watch my videos.

Hi Jacky, I think your outcome should be expected, as i remembered someone in this forum said each kind of beans has its own best settings, including the amount of grounds coffee and the coarse level. I have read some forum saying the best state (temperature, pressure !? maybe) for silvia is to try making the heating light on (by turn on the brew button 1 to 2 secs and turn it off for 1 to 3 times, really depends) and then wait until the light goes off, and wait 60 seconds before perform the actual brewing. Now i think this can be a fixed factor.

1 thing i agreed with you that, for some beans, using 18g is almost too much and i can't even lock the portafilter in the machine.....

Have you notice sometimes water with comes out from the edge of the portafilter when brewing coffee? wonder why is that happening....

I think your explanation make sense, i saw shing marked the machine for the angle of how far the portfilter needs to locked on to.. normally i think if i can lock it perpendicular to the machine base, i should be good enough, but, i have saw videos of silvia brewing , the person lock the portfilter further than perpendicular, which means a little to the right hand side.

thinking if Shing needs to use marker to mark this down, this is for sure a changing factor to the coffee brewed.

Thanks Icarus!

I cannot confirm how fresh the bag of beans is, that's why i am thinking to buy 400g freshly roasted beans from Landy to do test again.

I'll upload videos after that.

THANKS AGAIN!

i have got 2 more bags of the same italian blend and done 8 more tests to confirm if i am consistent on my outcome. As Neo suggested, avoiding dead spot, that is now i am focusing on.

17.5g | coarser | normal tamping | take 60cc
1st trial - not bitter and not sour - 48secs - with dead spot
http://www.youtube.com/watch?v=95QHrdiXCV8
2nd - sour - 40 secs - still with dead spot but better?
http://www.youtube.com/watch?v=1OZIHrEt7Js
3rd - sour - 37 secs - still dead spot on the left
http://www.youtube.com/watch?v=Cx45TqhLTV0
4th - sour - 37 secs - no dead spot!?!
http://www.youtube.com/watch?v=8xCzd_eirQ4

17.5g | normal marked grind | normal tamping | take 60cc
1st - less sour - 40 secs - no dead spot !?!
http://www.youtube.com/watch?v=a42EV_GiXr0
2nd - bitter - 48 secs - maybe due to heavy tamp this time - a little dead spot on the left
http://www.youtube.com/watch?v=1OZIHrEt7Js
3rd - sour - 40 secs - a little dead spot on the left
http://www.youtube.com/watch?v=l5utXjCkZMY
4th - sour - 37 secs - no dead spot !?!
http://www.youtube.com/watch?v=VVRpJrjQd_g

This is the picture of what i meant normal marked grind on the black spot
http://picasaweb.google.com.hk/yumecow/112_PANA#5508231776154171666

if i can avoid dead spot, means sour is suppose to be the taste, so whenever i am getting some other taste, i made some mistake maybe?? but have i successfully avoid dead spot?

also 60cc, including crema or not including crema??

I am using another reply for my tests on fresh beans
