Im tamping pretty hard. (and I practiced on the bathroom scales to get a feel of it
)grind is a likely cause, though at 11 or 12 on the EM0480 its quite fine, and reportedly thats about where others set it (recommended espresso range is 12-16). Actually, the time for doubles is probably pretty close, and I shouldnt pay too much attention to the singles.
I dont have any high-accuracy scales to check the dose weight. might investigate eventually...
Is stale coffee likely to be a contributing factor?
Sometimes the pucks are nice and dry. its just occasionally they come out soggy.
Have been considering getting the model shop at work to make me up a properly sized tamp, that might help matters... pity the filters are just a beesdick over 2" ID as I have plenty of 316SS 2" bar available. will have to use 304SS to get the right size. (or Al). Will post a pic if I get it done...
eh, I dont get to practice enough... havent had a coffee all week.
