Hi All,
Question :
Does a bigger burr size compared to smaller one with the same geometry improve the quality in cup? Considering maybe both are the same type of grinder, very similar burr geometry and both aligned properly (ie. Eureka 55mm specialita - 65mm XL/Zenith - 75mm...

I just purchased a LM GS3 MP direct from La Marzocco. Ordered in January and it arrived last week. The Shock Watch that they put on the palletized box was red meaning that the machine had been dropped and/or impacted. LM is trying to convince me to open the box, set it up and...

I was just doing some work on a new-to-me machine and was reminded how much soft jaws that actually grip but don't scratch chrome or distort bolt threads just make things easier.

These are a Knipex 10 pliers wrench with added semi-hard plastic jaw protectors. The wrench...

I am interested in trying out some flow and pressure profiling AND As I have owned for many years a double boiler e61 machine with a PID, I was thinking if buying an after market e61 flow control device to have my machine installed with it.

On the other hand there have been...

So I managed to pick up an SCL for a great price today. It's my first lever, and I'm excited.

Have a couple of questions though that I couldn't find answers too:

1. What's the red light signify?

2. What should the pressure gauge say at idle? I've read that thermosyphon...

I got a Kenyan coffee from it through Fellow Drops. It is flat and harsh, not bright. Does not seem like a Kenyan coffee.

most baskets hole patterns are not edge-to-edge (the unifilter might be the exception). so essentially there is a wall of coffee along the edge that when water passes through does not have a direct exit and needs to migrate inward to reach an exit path. This essentially means...

I have a Weber EG-1 and I have been using the Core burrs for straight espresso (light medium and dark) for 12 months now with great results. I have a set of the Ultra burrs and would love to hear from anyone who has used them for espresso. Very interested in your experiences,...

I understand that an HX machine has a single boiler, usually on the steam side (I think) and somehow the heat gets to the other side to brew espresso. The boiler is pretty self explanatory. I called one of the retailers to discuss selection of a new espresso machine but they...

I'm looking into buying a new espresso machine.

Since I only drink milk based beverages such as Cappuccinos or Flat Whites, except for maybe occasionally Americanos - but never Espressos - one question is whether to spend extra money for PID. Note that I almost never make more...

I have an Acaia Lunar and a Brewista, but I would like a cheap extra scale that can get knocked around. Has anyone tried the cheap Acaia copies on AliExpress, like this one

Are there any ones to steer clear of?

I'm getting closer to finding my recipe , but there are so many possible variables that it's hard to now which one to adjust I think I'm pretty close with my dose, grind level and base temperarture. I have a Gaggia Classic with PID and changed all the other changeable parts and...

Thomas added some major new details about the second edition in his blog today. We're starting to see what the price increase from the first edition can bring, e.g., 316 stainless steel instead of 304.

ETA: Other changes and the build process are on IG at: Some of the other...

Interesting new tamper. Non English video but you will get the idea. Also read more here

Hello!
Filip here, I'm new here, and new in espresso. Also sorry for bad english, hope you will understand me.

Please help me solve my problem, every espresso shot I pull tastes sour. Not fruity sour, but so sour it hurts when I try to drink it.

I use Gaggia Carezza Deluxe...

I'm looking to move up in grinders. Presently I have a Baratza Sette 270wI which I find OK. I've always had a desire to try to trade up the Sette to avoid the inevitable demise of the Sette's plastic gears. So I now have a line on a used Mahlkönig K30. I've also been eyeing the...

As an old auto racer, I'm well schooled in proper monitoring, maintenance and renewal of vital organs in mechanical devices. So when I bought my Technika Profi IV in January 2017, I vowed to disassemble the group every year for inspection, cleaning, and light lube. And I...

There has been script around that worked on some platform but a group has released an Apple and Android ap, Coffee Grind

You get a distribution chart then details show a report:

Disclaimer: I'm a newbie, just started brewing my own espressos at home. But I did watch a ton of videos, read a lot of pages on espresso and am trying to follow the advice that I found. The issue is that the recommendations are contradictory.

I have a Solis Barista Perfetta...

I'm about to pull the trigger on a Lelit Bianca. The only think I'm still not completely sure about is temperature stability (within the shot) and temperature repeatability (shot-to-shot). Does anyone here with this machine (or a similar dual-boiler E61) find either of these to...
