I've just started playing with a VST basket, wow, huge difference. Much finer grind required for a 2:1 brew ratio at around 27sec. Do you guys include or exclude pre-infusion time from your pull time? I'm finding the shot a little bitter when excluding it, but in reality that equates to a 33sec ish shot time, which feels bit slow.

I start timing from when I lift the lever and stop when I drop it (pump on to pump off - I don't 'delay' full actuation of the lever). Unless you're plumbed in (with line pressure) preinfusion isn't really a thing on these machines, though the design of the group does give the puck a little splash as the lever goes past the mid point.

 

The time is just a vague reference point really, just for interest and for the sake of describing shots. Better just to weigh your grinds in, and weigh the final shot, to find the brew ratio. If it tastes good all's well, the time bit really only comes into it if you think there's a problem. If it's faster than say 25" or slower than say 45" you might want to adjust the grinder.

I would include it if you must pre-infuse. After lots of experimentation when I had that machine and same with the R58, personally I don't bother with pre-infusion as the E61 gives an element of that any how with a full throw of the lever. I personally think it just adds an unnecessary variable and found the best and most consistent results this way and just playing with grind or dose until i got a taste I liked. BTW, Do you have your machine plumbed in? If not, I am not convinced the pre-infusion works particularly well anyhow.

Hot Metal summed it up better than me.

Yep thats the one 1:2. My machines plumbed in, but I'll try without pre-infusion, should make the timing more sensible I think :)

Really time isn't as important as you think it is . Just time the same each way . Don't stop pre infuse as it makes timing " easier " just note time don't adjust or measure by it
