difficult to say, you assume that the blind filter is set at static pressure , but WHY is the OPV discharging all the water in circle (that's the actual pump flow rate at the set pressure): it could not be more dynamic than that..... Pietro

I still do not understand if you agree with me, since I am saying exactly the same when I say that blind filter setting sets MAXIMUM pressure in brewing circle before OPV spring collapses and discharges excessive pressure: in a dripping tap the main pressure is the maximum OPV pressure, main pressur...

I am not trying or pretending to be the clever one : with a blind filter you know exactly the pressure that you have in the brewing circle, and you have the pressure meter fit at the end of blind filter, of course when you actually check the brewing pressure you have to place the meter somewhere alo...

When I am wrong I do apologize, still Mr. Warren CANNOT state stupid things; being technical director brings also the responsibility to put out correct information. I see from your posts that you are a kind of authority in the sense that you back your posts with personal experience, so you SHOULD NO...

with all due respect to your expertise in espresso please do not try and change physics : 9 bar is 9 bar, in the sense that at such pressure the OPV spring will open and release excessive pressure (keeping pressure in the brew circuit at set pressure, 9 in this case), you would ONLY run at 7 bar if ...

We'll probably see that at HOST 2009 in Milano late October, and then the entire industry (and not just a few of us) shall know who the westerns are a shame that this first product does not show any of the fresh ideas, if a good day you see from the morning this product is not any better than say

a grinder is designed to grind, a doser is used to consistently deliver precise volumetric portions in a commercial environment, still ground coffee goes stale very quickly and therefore the need for doserless. Forgetting the argument of purists who insist on need for degassing ground coffee ( no fu...

There you are: if Dan, who is clearly a veteran, finds it unacceptable (a blade grinder) it must be non suitable, much better a hand grinder (they seam to be all conical burrs, that were invented long before flat burrs) I agree that a good grinder is vital, but there seems to be a very large selecti...

I just forgot to mention the Pasquini LUX grinder that comes with Livietta, stepless continuos adjustement and conical burrs, promises to be a very good purchase, and necessary complement for great espresso.... but then do not forget the BEANS

You could go for a Pasquini LIVIETTA T2, it seems the perfect size, double thermoblock for coffee and independent (thus unlimited) steam supply. And it does not look bad at all : do a little Google research and find available vendor nearest you: hope you will be satisfied
