Posted Mon Jun 16, 2014, 4:34pm Subject: espresso noob (sort of) seeking preinfusion help
I've been making espresso faithfully, on a daily basis, with my Gaggia. Same machine for about 3 or 4 years.
Today I went ahead and purchased a Crossland CC-1. The CC-1 has a digitally timed, variable control preinfusion. Up until this time I've had no control over how long my puck gets preinfused. With my new found control, though, I have no idea where to start. What would be a good amount of time to preinfuse the puck? 3 seconds? 5? 12 hours? (I kid)

I have mine at preinfuse for 2 seconds and dwell for 3 or 4 can't remember. I then time from 1st drip not total time shown on the screen. So 1st drips usually start around 8 seconds or so, so I'll stop the shot at 38 for example for "30" second extraction (just an example, I'm usually around 36-39 for double depending on when 1st drips start). Some go by total time, just play with it and see what taste best to you. Think my temp is 202 or 203 on the blend I have right now.
Make sure your giving ample warm up time, I let the machine warm up for about 30 min or so with the PF lightly locked in. Then I pull a blank shot to get water flowing (vibe machines generally have a delay for water on the 1st shot, hence sink shots lol, doing the blank pull helps fix that) and make sure everything is nice and toasty.
