The ranking of burrs for brewing for 98mm are :

cast mahlkonig pre 2015> SSP 98mm Low unifomity> ssp pre 2015 clone> mahlkong post 2015 burr> ssp 98mm high uniformity.

Your friend must be excited for the new grinder, but if he will compare the burrs he will find the 98mm hu behind versus others.

Also if you have a max with suriken, why are you looking for a new grinder then? lab sweet (I consider it a weak grinder) and eg1?

I want another grinder for brewing only (Max isn't for brewing 🙅🏻‍♂️). I like the lab sweet looks even though I haven't tried it yet but I've seen a lot using it like the April Roasters' Barista Champion (forgot his name). Should I get the Ultra grinder instead? It's cheaper with multiple choices. My brother is chiming in with the brewing grinder😂 he likes pour overs a lot.

It's hard for me to believe that is espresso grind size, not that I dont trust you...

No trust required - the grind was set for my former machine, a La Spaz with a dying pump. I do expect to go much finer when the Evo arrives.

Not only will the grind size, weight, temperature and pressure have to be determined per roast but also which basket tastes best to us - stock ACS, IMS or VST. The right tamper to fit the chosen basket will lead to another important test not often mentioned: tamp weight and consistency.

Only with the correct tamper diameter can the correct tamp weight / depth be determined. Below are a couple of photos of the setup that helps me find the correct weight / pressure. The reading is in compressed puck depth in thousandth's of an inch.

Unfortunately, this device is banned by the wife for daily use or even be left visible on the counter so a custom Espro or some other calibrated tamper will likely have to be ordered.

The Ultra excels at espresso I agree. With pour over you get great clarity but at the expense of a more balanced cup. Can see why this wouldn't be to everyone's taste but some love this. I found that seasoning made a big difference with regards pourover. I've now put well over 20kg through and at pour over it has definately improved. How it compares to other 98mm burrs sets I've no idea as the only other set I have, which I've yet to try in the Ultra, is the pre 2015 EK Turkish

I can see why it was banned by the wife - it's not a thing of beauty! I don't want to know how slow your prep will be with that either

My friends id on HB is Codes123. He's the one sharing videos on the Lagom P100 thread. He seasoned it with over 65+ kgs. I think those big SSP burrs need 100kg to be fully broken in. Enjoy

 

[Stevebee]

65kg! I know Eric from LeverCraft did some particle analysis at various stages of the seasoning process. Big change 0 - 3kg, much less between 3kg and 5kg in comparison, but a significant change again from 5kg to 10kg. Didn't mention past that. This change in performance was most significant with regards pour over apparently. Actually I must have put nearer 50kg through when I add it up.

Does make for easy consistency. Just pull until the desired number is reached and presto. What - you don't like its looks? Hard to believe.

 

[SL01]

...over 65+ kgs....

That's something. I should start adding to my pile.

There are clear basket comparison on diaspora showing the E&B have a massive drop in EY (2-3%).

I have found the same with my combination of a 2014 L1 and a Monolith Flat with Shuriken burrs. The taste is correspondingly pallid. But others report great results. I wonder what they are doing differently.

There are people who want a simple way of doing espresso and I can respect and understand that.

This is why you see baskets like E&B superfine or HQ14. These baskets have a much narrow total holed area at the bottom, making you grind much coarser and adding a much higher resistance to the puck.

If the most open baskets are VST/Pullman followed by IMS and the further away from them are pressurized baskets that you dont need a grinder with the HQ14 and E&B superfine are baskets are in between and they let you grind coarser and at the same time user smaller doses (some people are afraid to use higher doses cause coffee is expensive or they can't drink many shots per day).

It's just a different view on what you know espresso should taste like and what you like. The same thing goes with Reneka microsieve that I had, same black ring with under extraction at the edge.

VST baskets are good, but need really good puck prep, prepared with a lot of attention to everything, the grinder has to be dialed in spot in meaning you dump 2-3 shots to get there. Some people dont want this and they drink almost all shots (99% of them). This is why grinders that are easy to dial in are successful and this is why you see baskets like the ones above being favored by many. Nothing against them, just a different approach to making espresso.

As for tamping, I find the bravo to be really consistent in tamping pressure, I tamp with 12-14kgf on top of the bplus.

And on-topic, I can't wait to get the machine and play with it. I am preparing some coffee meetings as soon as it lands, there will be many many grinders and a lot of good beans.

I feel this is the calm before the storm, right?

That or holidays starting in Italy/ACS in which case maybe the Calm before the calm 😉

 

[Denis S]

Then the mail from Paolo asking if we are at home in August makes no sence, or? 😆

Let me hope.

 

[Stevebee]

It's not a lot of time to get them made, balance paid, and shipped but like everyone else I live in hope

The calm before the Vesuvius (Evo Leva) eruption... 😂

Every time I receive an email...

 

[MediumRoastSteam]

Well... Let's hope ACS doesn't call a future machine Pompeii or Herculean.... 💥

Izzo has beaten him to one of those …😁

All Black hopefully 🤲🏻

I have finished making the 10 seal tools. AIl have been tested for fit on the piston from my machine. I haven't had the opportunity to test one on a really stuck piston yet, I'd love to hear from anyone in future that has.

I'll contact those on this list shortly to make arrangements if still interested.

I now have material to make more and will post an ad in the classifieds when I have finished another batch. Price will be £35 plus £4.30 for Hermes delivery in the UK and delivery at whatever it costs to everywhere else.

I have part finished some dosing rings, I could not make them with a lip that fits over the outside of the basket as the outside diameter is too small, I have tested them for fit with the standard double basket. I can offer them to anyone on this list for an extra £25 with a seal tool which takes into account the savings in postage. There may be a slight delay for me to finish them. Here is a picture of one I made earlier. The stuff that I make will never look like CNC machined goods, I prefer to think of it as hand made, artisinal 😄.

Great stuff Les - Evo owners are in your debt.
