I love my Libra. I upgraded to an atom 75 and eventually sold it and bought another Libra because I missed it
r/espresso • Weight-dosing grinders [$1000] ->Have owned all the grinders on your list, at one point or another. Agree that Duo might be your best bet. Ability to play with other 83mm burrs is a good hedge against future curiosity. Recommend getting second (filter) burr option, because having the extra carrier for fast(ish) swaps is nice. Cannot recommend the Eurekas. Good build, very pretty, but burrs are proprietary and the grind chamber/chute design is antediluvian. Fine for hopper base on-demand grinding, but crap for single dosing. Even with the mods (tilted base, bellows), retention is terrible. Eureka’s attempts at single-dosing focused grinders are not honest efforts. Just a new model name and superficial accessories. And their new dial is just…stupid. Still not enough ratio to overcome the thread lash in their adjustment screw. The rev counter is nice enough, but a big dial like [this](https://www.amazon.com/ARO-EspressoTM-Eureka-Mignon-Adjustments/dp/B0CLCB8VQ6/ref=asc_df_B0CLCB8VQ6) is much more effective (and not stupid looking, imho) Libra portafilter contact sensor was unreliable. I heard they fixed it, but I had given up already and moved on. When it worked, it was…ok. Weight accuracy wasn’t bad, but irrelevant because it was a hot mess of sprayed grounds. RDT absolutely necessary in my environment (20-50%RH over the year), but the extra moisture caused caking/clogging in the chute. From a taste perspective…it’s ok. Blendy, decent body, not a lot of clarity. Little unkempt and harsh. Good in milk drinks. Niches — good workflow, probably among the best, even compared against titan grinders at 5x the price. Personally, not a fan of Mazzer burrs. Harsh and bitter finish. The Zero doesn’t have any options for their 63mm conical, so you’re kinda stuck. The stock Duo espresso burr was, to me, a cleaner version of Zero profile. Other options: Mazzer Philos. The grinder itself is a bit pricey, and rumor has it that the i200D and 189D burrs are big improvements over Mazzer traditional flavor profile — but it’s a good platform for 64mm burr space, where you are spoilt for choice and the burrs are cheaper than 83mm. Hope that helps

r/espresso • Grinder Upgrade [£500-1000] ->Second a eureka mignon - Italians make good motors
r/BuyItForLife • Coffee Grinder - Simple , set it once and forget it ->My Eureka Mignon Libra is written "Made in Italy" ok it...
r/espresso • Chinese grinder ->I just got my eureka mignon Libra yesterday. It grinds by weight. Very happy with it so far. They run about $800
r/espresso • Weight-dosing grinders [$1000] ->Lots to chose from. Recommend Eureka - especially the grind by weight option - Libra
r/BuyFromEU • Looking for a high quality coffee grinder for espresso machine. Simple build but high quality parts. Any suggestions? ->The Eureka Mignon series will grind to the 190-195 micron range depending on which model.
r/Coffee • Extra fine coffee grinders ->Eureka XL, Eureka Libra, and Weber Key M1 are the 3 grinders on my bar now and it’s what I found on the secondary market for good deals. If you are patient you can find some killer deals. I won’t say how much I spent on each one but I’ll say that I usually don’t buy a grinder unless I can get it for 50~% off. This way if I decide down the line to sell it I can usually easily recoup my money and pass on the deal to someone else. I have had a bunch of other grinders on my bar over the last few years but they come and go depending on what I can find. I’ll likely swap out one of my Eureka grinders in the near future Iv seen a lot of grinder go up for sale in my area and the two Eureka grinders are to similar in taste. For now the XL serves as my daily, the Libra as my decaf, and the Key is mostly used when I try out some new beans. But I also really like to brew my daily beans with it but it requires more time and energy to deal with vs the 6-7 seconds from the XL.
r/espresso • What grinder do you use, why, and how much did it cost? ->Ja mám už roky delonghi dedica s vlastným sitkom a pákou (neviem, ako sa to po slovensky správne volá) a eureka mignon mlynček. Do 500€ by si sa mal vojsť.
r/Slovakia • Kávopiči poraďte kávovar ->Ode2 and Baratza Encores are the buy once for AP/PO. I’ve had my Encore for years pushing AP or doing the occasional PO. I also have a Eureka for espresso and 1z JX Pro, but once you go electric, it’s a luxury. I only take the manual when travelling or at our cottage.
