There is a new grinder about to hit the market from Bella Barista the T64, **not to be confused** with the Profitec T64. It's a 64mm flat burr grinder, produced by a Chinese manufacturer, I had a prototype and already a few enhancements have been recommended by me to BB so they can fine tune their offering. **The grinder in the video doesn't have an extra movable zero collar, the revised grinder does,** and it means the zero point can be adjusted should you ever change/use different burrs. The BB grinders will have this as standard. [upl-image-preview url=https://i.imgur.com/P1d9vPj.png] Secondly, the grinder can be purchased with Italmill, Chinese, or SSP burrs. **Bella Barista have decided to only offer it with SSP burrs at this time.** I truly don't know what burrs mine has, but I suspect it's not SSP burrs, even though it's working great! These videos introduce the T64 grinder, it's a nice variable speed flat burr grinder that produces excellent in cup results. It's is being launched by Bella Barista in the UK. https://bellabarista.co.uk/ The power brick you see is for my cabinet lights, the grinder plugs directly into the mains and is 230/240 volt. The grind cup, extension funnel and forks are all for the standard 58mm porta filter and made of good quality thick aluminium, not plastic The grinder is being returned early next week, so any questions, ask them quickly. https://youtu.be/VZYepwWagvw?si=b5Uk_yfMl28Aan73 https://youtu.be/XQLxMeQupsA?si=6tNlNFMCLu-5bFzs Now if you read this far I don't feel it's appropriate to disclose the planned pricing of this grinder in advance of BB announcement. But they will be doing a forum special at a price that if they step up and do what they say, will be unbelievably good and I don't say that lightly.

Thanks Dave, there is a "BG T64" on YT that may be the same. Looks pretty solid. Pretty sure the burrs are not SSP given the color variation but videos and lighting can be deceptive. https://youtu.be/vX-StUEhe4A?si=c44173JKA3buBr9z One concern in the comments in the YT thread was "it's stepless until it's not" referring to the dial drifting under load to a stepped point. The video was front August 2023 and it's normally an easy fix for the manufacturer so I'm wondering if you noticed any drift in the unit you have?

> @"tompoland"#p63075 The video was front August 2023 and it’s normally an easy fix for the manufacturer so I’m wondering if you noticed any drift in the unit you have? I got my unit from BB in January and it was stepped…I (damaged the stepped pin to jam it in, as you can't pull it out), this made it stepless. I did this after realising going in between steps was imprecise, it would possibly "fall off" the steps and move…plus it wasn't mine and would be going back (It actually is being collected by Bella Barista next week). As stepless, it's never moved or drifted at all and the company have been asked to make the BB grinders stepless. Also to add a re-zero ring as they might be factory zeroed, but if people change burrs then the zero may be lost. Also the factories zero might not always bee 100% correct. There is one big difference you perhaps didn't spot…**it's not variable speed**, mine goes from 800-2000 rpm, which is how I can use it to clear grinds without using the bellows. There are some other differences in the video to the unit I have, some small some larger * **The grinder in the video has a 200W motor, my unit has a 300W motor** * Aluminium lid with wood top cover on mine (looks nice, adds a bit of contrast. * The ring that fits on top of the grinds cup has two grippy o rings machines in to it stays in place nicely * The grinder I have it I believe slightly heavier. But they look like they are from the same company and offer the same 3 burr options…obviously I suggested to BB to only use SSP burrs, because they are a known quantity and the quality of construction merits it. *P.S.The Evo portafilter funnel for LSM size portafilter from Norvin (thanks again Norvin), fits a groove in the grind cup perfectly as you saw on the video, making it super easy to use with my 53.5mm portafilters*

How would you compare it to df64 if you have used both? Also any way for non UK customers to buy it without having to ship from BB?

> @"delta76"#p63111 How would you compare it to df64 if you have used both? Also any way for non UK customers to buy it without having to ship from BB? I actually have a DF64 and it in my option the T64 is a much better grinder. and more accurately made. Oh I forgot to mention once it's finished grinding, after 2 minutes it switches off, so they really have thought about the product and the grind cup etc.. I have no idea about availability and retailers world wide, if you are in Europe BB might well ship it?

@"DavecUK"#p63112 - did you manage to find out more about the phenomenon of no static what so ever? Is there anything special? Given high end grinders come with a spray bottle…. This is an achievement in itself, whatever they did!

@"DavecUK"#p63112 if it comes to that I might have to, but would prefer to buy from a local retailer or at least from within EU to avoid tax complication (and warranty also). Great to hear it is better than df64 in your opinions - i know you pay very close attention to details!

> @"DavecUK"#p63112 actually have a DF64 and it in my option the T64 is a much better grinder. and more accurately made. Interesting thanks Dave. Can you shed some light on "more accurately made" and is there anything else that you prefer over the DF?

> @"giampiero"#p63128 Any stalling issue? As I said in the video and description as well I think, **no problems with stalling**. I run it at it's slowest speed 800 rpm, **I don't hot start** and in the video you can listen to it grinding. I have also tried some of @"LMSC"#16 light beans in it as well.

> @"tompoland"#p63120 Can you shed some light on “more accurately made” and is there anything else that you prefer over the DF? not really, it's just more accurate, no o rings to centralise the core as in the DF64, and accurately made is just that, especially in the burr chamber…all milled aluminium and no wave washer. It's just a nicer grinder to use and especially adjust. The looks of the grinder ittself and accessories like the catch cup etc.. are way better.

T64 Grinder From Bella Barista

DavecUK

steve_07 any thoughts or ideas?

Seriously, don’t worry about it, you won’t ever taste it…. 0.5g variance is nothing.. After all Hoffman won a word barista Championship of grinders with far more retention than that and with scales that were probably not as accurate as they are today.

Adrianmsmith

But, if that retention is consistent then there’s nothing to worry about.

If your losing .5g per shot on the other hand then you reinvented physics 😎

steve_07

Adrianmsmith need to use it more to see if it is. may up the rpm to around 1200 for espresso and I’m sure that will solve most of it.

haha very true. I’m not losing .5g it’s being misplaced 😂

steve_07

So think I have found the retention reason.

I opened up the grinder and the sweepers were backed up with coffee and the exit chute was blocked so cleaned and unblocked it all then first grind I’m a gram or down so open up and again the chute has blocked.

Think I’m the only one struggling here with a blocked exit chute and I’m not sure why. I am using coffee currently which is not the best I have ever drank or purchased but that shouldn’t be an issue.

I haven’t taken the lower burr out to see if there is an issue there. I presume the carrier is fixed.

Picture below to show what it looked like inside.

I’m thinking to remove the fork as that looks like it pulls out from the top to allow less resistance on exit.

Any ideas if I’m at fault or grinder issue?

DavecUK

steve_07 Any ideas if I’m at fault or grinder issue?

Possibly the coffee?

Adrianmsmith

steve_07

Mine is staying clean in those areas .

I’ve been doing a puff of the bellow followed by Dave’s, “turn it up to 11” , one more puff and turn it down again. Usually just in time for the timer to turn it off.

Are you rdt’ing. I see no reason to do so .

DavecUK

Adrianmsmith Are you rdt’ing. I see no reason to do so

Definitely not, I think RDT can cause clogging and I have not found it necessary with this grinder.

steve_07

So 2 18g doses of good coffee this morning from different roasters. Both blocked the forks.

I think I either remove that fork or ask for a replacement at this point.

Edit: pulled the clump crusher out (the forks and shim are one piece) and the top part was clogged completely. No chance of freeing all the grinds without removing it. I’ve cleaned it all up and put it back in. See how I get on later. If it clogs again I’m going to remove it and see how the static etc is.

giampiero

Silly question, maybe are you grinding too fine? I asking just because the “retention” in your previous photo seems very fine.

steve_07

giampiero

Not too fine as the shots from that are pulling normal not choking or anything.

I did remove the declumper and grind which I do not recommend you do, the mess is horrendous 😂

I have however bent the shim slightly just to give a little more clearance between it and the fork. 2 grinds after have been .2/.3g retention after a puff of the blower which is fine. A little static but not terrible (hate fines blowing everywhere!)

Leads me to think not enough room to exit was causing blockage and build up.

If anyone who has one pulls the declumper/shim thing out you will understand what I mean.

Adrianmsmith

steve_07

I don’t get where all these .3 .2g are hiding.

I get 20.8 20.9 21.2 21.0 20.9 21.1 etc etc from my 21g doses obvs averaging at 21g over a period.

Just for you…. My method and build up.

No editing

No cleaning

Just genuinely as found

Here’s a duo shot

And a t64 shot

Just for “fluffy” comparison!!

steve_07

Adrianmsmith take it that’s 800rpm?

no matter what I do the declumper is clogging and in turn that cakes the sweepers up

Just going to ask for a replacement I think.

Cuprajake

What’s the coffee? And have you tried another bean?

steve_07

Cuprajake

Baytown was causing the build up but it just occurred I’m being a bit stupid.

if I remove and clean the declumper after the grind the next grind coffee will build on it again hence a lower output.

So I’ve put some scenery and rave through it and touchwood the sweepers are as clean as they should be. Top of the declumper is covered but when I think about it, that’s going to happen!!

So it looks like it was the coffee after all and me being a bit ocd with how much coffee should be left on the declumper after grinding!!

MediumRoastSteam

So strange. It doesn’t seem to be an oily or very dark roast given the colour. And I take you are not using RDT or grinding from frozen or anything like that?

Are you hot starting? I don’t know why @Adrianmsmith is hot starting his… not sure if it’s required or not.

Adrianmsmith

MediumRoastSteam

For me it’s just “habit”

Obviously I don’t hot start the duo so have no reasonable explanation why I do the T!!

It just seems right 😎🙃

It’s apparent from other threads that what seems right to me doesn’t always sit right with others, even though I’m never wrong. ROFL. 🤔🫣

steve_07

MediumRoastSteam around a medium roast, no RDT and not frozen or anything.

yes hot start but don’t see that making a difference.

It looks like it’s the bean causing it.

DavecUK

steve_07 It looks like it’s the bean causing it.

As I suspected and said many posts up.

Re other comments from others.

you don’t need to hot start (unless you find a bean that stalls it…I haven’t yet)
Don’t RDT

I grind at the lowest speed…

steve_07

DavecUK the sweepers are back up again and that’s a different coffee and retention was .5g and that’s after bellows.

something a miss to me. Will drop Bella Barista an email.

Adrianmsmith

steve_07

When you keep mentioning retention is that for a single shot after a strip and clean, which is to be expected or is it shot to shot for say 5 in a row ….

dfk41

steve_07 Hi, how do you know that your scales are accurate? Personally, o.5 gms would not bother me in the slightest!

steve_07

Adrianmsmith no it’s a few shots.

Not sure if I’m making a mountain out of a mole hill but the sweepers shouldn’t look like that and the declumper shouldn’t look like a wall of grinds with a tiny hole in the bottom where some is forced out.

Just doesn’t sit well with me. Am I wrong?
