It's still the good ole Giotto but I have added an external Rotary pump and motor. The pump and motor went into the lower kitchen kabinet and brewing is now niiice and quiet. No more shouting to overcome the vibration pump noise and no more rattling from the cups and glasses on top of the Giotto.
To get more control of my cooling flush and brew temperature I bought an EricS Thermometer Adaptor for E61 brewgroups. How have I ever coped without it??
But thats not the only change...
You can say there has been a "Major" change in the grinding department as my loyal Mazzer Super Jolly has been exchanged with a Mazzer Major. Not as big an upgrade taste/grind-wise as going from the Isomac Granmacinino to the Mazzer SJ, but the Major delivers just a little bit better and fluffier grinds at record super speed. I have my timer set at 3,5 seconds which gives me 17-18gr of espresso grind in the portafilter. I bought the Major second hand but it was in very good condition and after a change of burrs (these guys are intimidating 83mm) and the usual Mazzer mods (see earlier posts) it was good to go.
Have a look at the updated setup on this video
and check out the (whisper) quiet brewing with the Rotary pump action.
