I don't have any flat burrs sets to compare this against except the ones in the timemore 78s. That being said, I definitely prefer these and find my first few bags I've tried on it to live up to the hype surround these pro burrs. Make sure you oil up the lid Gasket though, otherwise it's a pain to remove as many have reported before

Is this grinder perfect ? Nop, you've probably read or heard that the grinder is not quite stable when grinding, the seasoning takes a good 2kg of coffee to peak. Add to that the pre-breaker blocks you during grinding.

What do you get?

A superb grinder. It's quite the Alpha Romeo. You love it with all the flaws. The clarity and separation of flavour is unmatched in my view.

I have and use ZP6S and it is above that. I use the Lagom P64 High uniformity and it beats that too for filter.

I do trendy turbo shots with Ultra Light roast and love it all that much.

I definitly would recommend to anyone looking to explore the possibilities of new and upcoming coffee.

All along my espresso journey, I’ve used conical grinders. A few years into the hobby, I wanted to try a flat burr grinder, but I didn’t want to spend thousands on a well-designed, high quality flat burr grinder just to satisfy my curiosity! The Pietro manual flat burr came onto the scene a couple of years ago & provided the less costly option, but even at that, it was a considerable outlay, so I continued to resist. I almost gave in last year when they offered a great deal that included both burr sets, but talked myself out of it, for the umpteenth time! However, when I saw the sale price this month, I thought ”Right-o, enough with this waffling back & forth, bite the bullet, take the plunge.”
The Pietro arrived today. And, wow! I cannot believe what a delight it is to hold & admire, and the cup result really does deliver. I should not have waited so long to buy it!

First shot from the grinder:
Using Dak’s “Cinnamon Roll”, set the Pietro at “2” for a 15 gram dose of espresso, pulled on the Flair (previously dialing-in on the Niche at #10). The manual grinding process is what you’d expect… not super quick & easy, but definitely not as hard as so many have stated. I am a senior with arthritic hands, and I didn’t force the grinder one bit, just let it grind at a calm pace, backing off on the handle if a bean snagged in the burrs, then resuming forward again. No real effort involved as long as you aren’t trying to force the process. Slow & easy wins the race. My hands aren’t huge, so clearing the counter with my fingers is not the problem others have described. Still, I suspect I’ll go with a sitting-down mode, grinder on my lap/fishing reel style, more often than not (with lighter roasts, anyway). And, yes, the hopper lid is vacuum-tight, but easily lifted using a thin-ish wooden popsicle/ice cream stick (Haagen Daz😉): give it a twist when slid into the provided side gaps & the lid pops right off the hopper. (The wooden pry tool won’t scratch the surface. You wouldn’t want to use metal!)

The grinds are BEAUTIFUL coming out of this thing, so even, fluffy & perfect. There was fair bit of static initially (no, I didn’t RDT) & I think I lost a bit of my dose as a result, either that or more likely due to some grinds retained in the burrs… but this was my first go using the Pietro, so I will become more familiar with what to expect in due course. (I may end up dosing a bit higher to compensate, need be.)

I poured grinds direct from Pietro grinds cup into a Weber Blind Shaker, easy-peasy, as there’s lots of room with the blind shaker to accommodate the grinder cup’s odd shape. I can see it might be awkward if dosing directly into a smaller diameter portafilter, and more so because the interior of the grinder cup is black & hard to see if all the grinds are out of there. (The Pietro cup has a convenient “thumb hole” to aid when tipping out the grinds.)

The AROMA was incredible! Dak beans have beguiling aromas, but they literally sing out of the Pietro, & that aroma spills over to the brewing process, too! Big plus there.

The flavour: Right off the bat, I notice the SMOOTHNESS & the ROUNDEDNESS of the shot. I regularly grind with a Niche Zero, and while the Niche does yield a very nice shot, it can tend to give slightly sharper notes at the end, whereas Pietro had none. The complexity may be more blended with these multi-purpose burrs, not sure yet, & I’ll have to try the Pro brew burrs at some point, to compare. But, again, it’s early days & this was my first shot. The flavours were all there, even & rich, without dryness or sharpness. Lovely.

I am DELIGHTED with this grinder. It’s massive, quite heavy, and not what everyone would want because of that. I really don’t find the weight or effort involved off-putting. And there’s a delight in something so solidly built & appealing in design. The taste in the cup is everything, and this delivers. Very, very happy with this purchase & my coffee indulgence.

I bought the MultiPurpose version as well as the ProBrew burr set. So far I've only tried the ProBrew for the pour over. I chose the forest green color, which looks much better in real life than on the pictures. As expected, the first uses are muddy bed, but still pleasant cup. These burr sets are known to require a few kilos of coffee before reaching their full potential. Ergonomics are not optimal, but all in all it's a pleasant experience and easy to use. The build quality is sturdy and excellent. The adjustement settings have a nice click feedback. I like the design, a lot of ingenuity. Quick to open for cleaning. I'm not giving 5 stars because the ergonomics aren't optimal and it's annoying that the burrs need a lot of seasoning to reach their full potential, but overall I'm satisfied with my purchase.

Even before seasoning the burrs, the pro brew burrs has given me some of the cleaning balanced cups for filter. Super worth it
