Posted Mon May 21, 2007, 10:34am Subject: Bad portafilter?
I just got my first espresso machine, Rancilio Silvia. I've done some practising and had troubles with uneven shots. I've done double shots to 2 cups (one for measuring the amount, other to drink). First I thought the uneven shots were because of bad tamping, but now I noticed that the filter holes in portafilter are not symmetrically stationed.
Have a look at this picture to see what I mean (sorry, I'm not familiar with the exact terms).
Now, as this is brand new machine, should I ask for replacement filter? Is it normal that the holes are not even?

Here is an example of shots I've pulled. Even though I tried to set the holes symmetrically regarding the left and right cup, it's difficult to get even distribution (could be tamping too). Right cup has less crema and coffee. What do you think about the crema in the left cup though? (Picture taken couple of minutes after the creating the espresso)

Even if you were using a naked portafilter, or a portafilter with a single spout (ie - not splitting the shot between two glasses), I'll bet this basket will overextract on the side with too many holes and underextract on the other. I would try to get it replaced.
