La Marzocco GS3 AV - Coffee Pressure Question

Hi folks, I have a GS3 AV. I haven't paid attention to it for a long time, but I just noticed that the pressure continues to rise above 9 bar (about 12 bar to be exact) during extraction (with coffee). When empty, however, at free flow the pressure remains at 9 bar. If I adjust the

New Eureka Mignon Single Dose Grinder

Thanks. Yes that is a different grid design. My XL looks like Specialita. That SD one should have less resistance. But why do people get clogging if the ACE gives less resistance compared to XL? I never have had this with my XL (and former Specialita)... Agree that the Eureka bellows only works with quick agressive pumps

Transfer Function for Cold Drip Coffee

So, today I found this paper: {link} Here's an Hoffman video about the paper (this is how I found it): {video} I'm still absorbing it bit by bit, in-between meetings, it's definitely fueled my interest in this subject though.

Awesome! Here's a recipe I ginned up to spoof a drum roaster, with a linearly declining RoR over a 9-minute roast that should land in the City/City+ range: {link} If at some point you can post curves from your Bullet, I can try cloning it onto the Ikawa, so the biggest difference between the machines would

Extremely Abused Pre-Mil 2 switch Pavoni.

This whole pavoni was abused horribly. Amazingly, the electrics are flawless. Anyone ever encounter this issue with a pavoni group? The siphon screws in and functions fine, but the screw which is part of the whole casting it seems has split along the thread on the very edge. There's no signs of deformation on the siphon so maybe rot plus

New Eureka Mignon Single Dose Grinder

The metal ACE thing works fine with bellows in my experience with the Specialita. But Eureka still shortened it for the Oro SD specifically to reduce resistance there. Photos comparing mine (7 weeks since the last cleaning, 4 shots per day) on the Specialita vs the Oro's (image from Rowsell's video, possibly bent after his "fix"). My Specialita: {image}

So frustrating to pick a grinder!

How about his and her grinders? Happy wife, happy life. A more practical solution would be be for you to pre weigh all the doses that the two of you will need each week into bean tubes. That way all she has to do is grab a tube, empty it into your new SD grinder and
