  • Flat Burr Grinder Recommendations

hthec I think people have been struggling with cast burrs, so would be surprised if this does well with them. The gorilla gear are quite a traditional geometry aren’t they? I’m sure they’ll be fine if so.

I’m actually not so keen on the aesthetics. I’m sure it’s probably the best performing grinder in a wind tunnel but I’d prefer to see it more angular, similar to the Weber Key. If they could work on the proportions a bit, even better. It’s interesting, that layout seems more prevalent with conical burrs, whereas vertically mounted flat burrs are becoming more common. I do like the look of the P64 but thinks it’s proportions are also off a bit, quite tall and slender. I’d just love a grinder that’s designed with out of the box alignment for that £500 mark. The kopi has at least produced a very good thing for a good price and proves it’s possible.

      🤣🤣 took me a while to get it but that’s brilliant! I agree with you on the aesthetics of the Weber Key and the P64. WW leaves a bad taste in my mouth though, and if you happen to have an issue with your product it seems you’re s*** out of luck.

      I was under the impression the Kopi Deva would have good out of the box alignment. Seeing some people struggle with their DF64’s, it’s become a major factor for me

        Great minds think alike. I’ve got an Argos on order as well as a Kopi Deva, both in steel with walnut accents. Got some SSP Red HU burrs just to get all fancy with it too. Looking forward to dialing both in once they arrive.

              ez4prez did you order on kickstarter or indiegogo? Seems they’ve been quiet on the updates. I opted to wait for retail for the Kopi Deva… now p64 is having supply issues too and I’m out of luck for grinders

                  hthec Argos I ordered direct through their website months ago. Kopi I ordered through Indiegogo, but am checking Kickstarter for updates. On Kickstarter they last updated in late June to say that a large portion of the team got Covid and were taking time to recover. Hopefully they’ll be back in the saddle shortly and have another update for us.

                    Hope so too, they seem really nice and passionate. Just to be clear i ordered the Argos but held off on the Kopi Deva because of the stated “non-compatibility” with SSP MP burrs. I was thinking to wait to decide between the Kopi Deva, the p64 and the new Acaia Orbit…

                      I did check the Kopi Deva, but can’t find anywhere to buy. Does anyone know how much it would cost for one to be bought/shipped to the UK?

                        MediumRoastSteam They closed the indiegogo campaign in May and have been working on fulfilling orders since. They hit 48% fulfilment at the last update on June 24 (not sure if this refers to Kickstarter only or total Kickstarter+Indiegogo). They plan to go into production after the early backer units have been fulfilled but no details yet. The team assemble and ship from their workshop in London so I assume the shipping shouldn’t be very much if in the UK…

                          Ernie1 Darn it, that looks very very good mate….may be poaching that idea, your dosing cup rest is so tidy

                            hthec why do you like SSP MP over other SSPs? Is it that you want one burr set to go between filter and espresso without having it change it out or have two separate grinders?

                                ez4prez just want to try it as a contrast to my current grinder which is a Eureka mignon. If I end up not liking it I figure I’ll just get a different burrset. Plenty of choices at 64mm

                                    hthec

                                    For burr choices, The 64mm is godly.

                                    64mm Mazzers for typical Espressos shots. Good in both espresso and milk based drinks. Decent for filter but not ground breaking.

                                    64mm SSP HU for those nice espresso shots with very good clarity with a decent punch in the body section. Might be good for drink based drinks but it is dependent on the coffee used. Not all coffees will have enough body to pierce milk based drinks. It is better than the mazzers even for filter.

                                    64mm SSP MP for those full fledged clarity espressos (The SSP 98mm HU is the same profile even though they say it is HU). 1:3 ratio shot and you got a tea like espresso drink that screams clarity. Forgot about milk based drinks with it.. no body what so ever. Was the go to for filter for awhile.

                                    64mm SSP Lab Sweet, The god of filter grinders. I kid you not… gives better filter shots than the P100 with 98mm SSP HU. In addition, In filter you can basically use it at maximum grind speed. Less fines at max speed. BUT… at max speed it is extremely bad for espresso. Too strong of a body. Lower the RPM to 400-500rpm and it becomes an excellent choice for milk based drinks. Forgot espresso on it at any speed. Too much body. I am talking body that will make a conical blush.

                                    I am currently running the following:

                                    Lagom P100 with 98mm SSP HU for Espressos.

                                    Niche for Flat Whites and Milky Drinks.

                                    Deva with SSP Lab Sweet for Filters and the lighter body coffees if I want to dabble in them for milky drinks.

                                    This combo is glorious and I don’t think I will upgrade anything soon.

                                        Otaibimn Very intressting comparison. If using the SSP HU for espressos do you notice any bigger difference if having low rpm vs high rpm?

                                            Tjyven There is. Going slower as a general rule with all flat burrs (Except for the lab sweet and conicals) reduces the number of fines thus leading to a different taste (Not much but noticeable and generally better clarity and lesser body) but leads to faster shots in espresso.

                                            So you need to balance how slow you go VS how fine you grind

                                            64mm SSP HU are generally good best at fast RPMs. Didn’t like the shots are lower RPMs since they tend to go turbo shot galore.

                                                Does going slower reduce the proportion of fines, compared to the rest of the distribution? Or does it make the whole grind coarser?

                                                    That is a very good question, as below a certain speed, the optimum burr packing speed, I believe the grind just gets coarse (from my experiments)

                                                        Otaibimn You get a lot of coffee, pull lots of shots vary the speed until the burrs stop packing correctly and the grinds become very coarse…plus the taste/texture changes.. You also need to monitor the load on the burrs for a speed that gives the most consistent load over time, plateau with steep sides rather than peaks with slow rises/falls

                                                        You then repeat the tests, for a wide variety of coffees…and select the optimum speed for that particular burrset.
