Manual Pre-infusion?

[nunu]

Ive been doing something lately, at home and at work that I feel has been giving me slightly better results; manual pre-infusion.

After locking the PF in place, I hit the brew switch for about a second or so, then wait a second, and then pull the shot.

Is there any merit to this technique? Or am I just fooling myself into thinking its doing something beneficial?

Re: Manual Pre-infusion?

Some machines preinfuse by doing just that. If you think that its giving you better results, go for it. Although your palate should always be the guide, using a naked pf to double-check might give you some insight as to whats happening.
