Great video, thanks so much!

Love the music while pulling the shot! In my workflow I do arms up preheating, but without the scale underneath. I fill to the brim and let a bit overflow so I know the piston is getting heated.

I use a rubber band to secure the arms too but I just wind it around the corner of one arm a few times and tie a knot. Then when you lift it up the friction basically holds both arms up in place.

First time seeing this machine, are the coffee holder and water cup the same unit? I missed something.

Great video, thanks. Why not just put Portia filter into a juj of hot water to preheat?

What is the minimum amount of coffee grinds? I find sometimes trying to make a small coffee the tamper doesn't even touch the grinds. I guess it can't do it?

Apparently around 10 grams (Paul Pratt the inventor posted a video of a shot on home barista some time ago).. less is not possible due to the shape of the basket I think

Paul was making them this way for while. My understanding is that it was more labor intensive and maybe not worth it to him? For awhile they would come out and then sell out right away. I think I got one of the last runs he did. I don’t know his plans but I noticed it said they are no longer available. I’m assuming that meant he is no longer producing them this way.

@worthashot9327

I usually do about a 20 second pre-infusion and a pretty fast ramp up to nine bar after that. My starting point is about 35 second shot time not including the pre-infusion… 55 seconds for everything

@@bowieknife I start counting when I add pressure. This is the arm start to move down, I count for about 15 seconds. Usually I start to see coffee accumulate around the bottom of the basket around 1/2 way through that time and hold the pressure for the other 1/2. I try not to let any espresso drip into the cup during the pre-infusion. And then ramp up pretty quickly to nine bar

Why do you need to warm the piston? I thought there is air between the piston portfilter so there shouldn't be any decrease in heat

@shanesettle7832

10 ай бұрын

I would suggest doing two things 1) try a shot without preheating and then try a shot with preheating. I am convinced there is a difference. 2) I understand that air is a good insulator. However, I just did a mini experiment at home. If you pull a shot and then feel the piston, it is quite hot to the touch. I suppose that could be explained simply by water, evaporating, and re-condensing. However, I decided to try to fill water up just to be low level that would touch the piston and let it sit there for 30 seconds to a minute. It only very very very slightly warm is the piston. In my opinion, the air gap must be so minimal or nonexistent by the time you compress the air that in fact, you do lose heat to the piston. Not sure if my above! Sense or not? Also, I do believe that Paul, Pratt and others have done tests on the thermal stability during shots and in fact, they are more stable and stay hotter when the piston is preheated

If you want to preheat the porta-filter just put it in a cup of hot water. Why is everyone bothering with these silly seals?

@worthashot9327

It’s not to preheat the Porta-filter as much as it is to heat the piston. www.home-barista.com/levers/cafelat-robot-temperature-tests-t65550.html

Why preheat the piston? It doesn't touch the water in the pro basket. It would be better preheating the professional basket, but probably unnecessary unless using light roasted coffee beans.

I don't think all this fiddling is needed -- otherwise I wouldn't put up with it, either. I bought one with the 'donuts' that make the lever ends a lot more comfortable. I also got the self-leveling tamper Cafelat offers. After that, I just use boiling water and don't waste time. It compensates for whatever heat the metal sucks out. I don't have to do any fiddling at all, and the result is better than 99% of the coffee houses out there. Cleanup is also a LOT faster and easier than with a regular grouphead.
