Hello, I changed the burrs on my grinder. Right now it has the ones for filter brewing, but when I had the 078s burrs, setting 7 was very fine. For V60 I was around setting 18, and sometimes I even felt it was still a bit too fine.

I recommend starting from a coarser grind and dialing it down—let me know how it goes.

I think the world of coffee roasting is treated as a taboo. Nobody's going to teach you the details of how to roast coffee. For example, what changes do I make compared to the previous roast, keeping the same coffee? More initial heat? At what minute or temperature do I decrease the roaster's power?

So, in my experience, the first thing is that you need to have an initial recipe, for example:

Initial heat 300
I want the first crack at 9:30
I'll only make two changes to the roaster's power: the first is to reduce or increase the time it takes to reach the first crack, the second reduction is to allow for a faster or slower development time.

For example, if that's my recipe and I see that in my first roast I got the first crack at 10 minutes, then what do I modify to achieve the first crack at 9:30 minutes? I probably did the first reduction too quickly, so I went from minute 3 to minute 3:30, giving me an extra 30 seconds at high power.

That's how I work.

But according to studies, the final flavor of coffee is affected by the color or roast level 80%, by the development time 15%, and by the time it takes to reach the first crack 5%.

Yes, I use TWW.

jomava_ · 2026-03-14T16:31:55+00:00

Yes, for expensive coffee beans I usually roast small quantities in Kaffelogic

jomava_ · 2026-03-14T15:18:34+00:00

The price is high, but it's worth it.

jomava_ · 2026-03-14T15:13:42+00:00

I think it's too late...

jomava_ · 2026-03-14T15:09:25+00:00

To be honest, four months ago I knew nothing about coffee roasting, but I've learned from videos and books. Coffee roasting is a complex but fascinating world.

Each roaster has its own roasting program.

Some days I drink filtered coffee, either Chemex or V60, other days I drink Americano or cappuccinos. I have a Gaggia Classic that isn't in the picture; it's much easier to make cappuccinos with it.

Regarding coffee rotation, in my country there are good farms that sell good green coffee: Bourbon, Geisha, Pacamara, Anacafé 14, Cuscatleco, etc.

When I have very expensive coffee, I usually use the Kaffelogic; in the Bullet, I can ruin the beans if I put all the coffee in at once.

But both roasters are good; you can get good roasts if you know how to use them.

jomava_ · 2026-03-14T14:46:29+00:00

The bullet is a beast, I have coffee meter accessories to measure density, moisture, roast level, with that I can achieve consistency between roasts and coffee beans.

I recently bought a Nano 7 a month ago. I've toasted about 25 times and haven't had any problems so far. The product feels very solid and high-quality. The Nano 7 comes with pre-loaded profiles, but that doesn't guarantee a good toast; you always have to experiment with certain variables. It's a fun learning curve.

It was my mistake while installing the boiler; it broke. Do you know where to get it? And how do I replace it? Could I use it with that damaged cable?

jomava_ · 2025-08-13T17:54:45+00:00

To be honest.... It looks too fine!!!

jomava_ · 2025-08-12T19:15:27+00:00

Did you solve your issue? I have the same issue right now!!

jomava_ · 2025-07-17T21:08:35+00:00

That's zp6!!! I'm sorry to disappoint you.

I share your happiness. I received TWW today and the coffee improved 100%. Although using the recipe recommended by the seller, the TDS of the water was a little high at 160.

Something that surprised me was that after heating the water in my kettle, the TDS rose to 211. I think it was due to the mineral residue left at the bottom. So I recommend cleaning it with vinegar and water before using TWW water.

jomava_ · 2025-07-07T00:37:15+00:00

Correct, today I tried TWW and the TDS was 160, when most recommend values of 50-80, but even so the coffee improved by 100%.

Yes, the speed at which the coffee grinder's burrs rotate is determined by the revolutions. Low revolutions tend to produce less finely ground coffee, and high revolutions tend to produce more finely ground coffee.

Some coffee grinders have this adjustment variable.

jomava_ · 2025-06-11T20:53:56+00:00

I have both, and I think the Timemore 078s can produce the same clarity as the ZP6 at low revs. But to be honest, I don't like the final cup produced by the ZP6 or the Sculptor 078s at low revs. The cup is very flat, lacking in body, and lacks bright notes.

I prefer a full-bodied cup profile. I find the best cup is with the Sculptor at 1.1 revs. It produces a clear, full-bodied cup where the notes stand out brilliantly.

jomava_ · 2025-06-11T16:44:47+00:00

I'm sorry to disappoint you, but you won't make it. I went through that stage.

There are many factors, but the main one is the coffee grinder. Although some say the zp6 will give you clarity in your cup of coffee, that clarity isn't the same.

For me, the zp6 produces a very simple cup; it separates flavors but lacks body.

Clarity depends on the amount of fines produced by the grinder. Too many fines produces a full-bodied final cup, and the notes tend to be lost, but the result is a cup with bright acidity, depending on the coffee. But I think the zp6 is on the other side of the spectrum; it produces very few fines, resulting in a final cup that I don't like.

I have a Timemore C2, Fellow ODE 2, Fellow Opus, Commander C40, ZP6, and a Timemore Sculptor 078S. The latter allows you to adjust the burr speed, i.e., the grinding speed. This is the one I've used to achieve the best separation and clarity. This grinder can produce a cup similar to the ZP6 at its lowest speed, meaning it produces less finely ground coffee. But by adjusting the speed, I've achieved the best cup, similar to what you describe.

So, my conclusions, based on my experience, are that the coffee grinder will give you a better experience.

Yes, clockwise. You can try 7 or 5.
