With all due respect, maybe some of you are over analyzing pre-heating the Robot's basket?

When I feel like pre-heating the basket, I either use Sam's ("samuellaw178") method (but without pouring water to the top of the basket) or Chris' ("yakster") method. For "yakster" method see post #47 in this thread (the basket gets really toasty, and because of its position over the kettle it is sort of a warming tray).

You can also pull a subsequent shot without pre-heating basket if only brushing-off spent puck from basket (but have your next dose ready).

With dark and medium (no oils) roasts I don't bother pre-heating the basket. I am using a PID Bonavita kettle, and sometimes I set the temperature to 205 degrees F, and shots still taste amazing. Half of the time I go for 1:1 shots (ristretto), the other half of the time I go for "normale" 1:2 shots.

I dunno ... I set my Bonavita kettle to 206°F. We'd better compare elevation, humidity, ambient room temperature to be sure we get this right. :idea:

What I WOULD do for a good cup of coffee!

Yes and thanks. I had another shot after posting, and, I left the basket out of the pf. Heated the pf inside of a regular drinking cup, ground coffee into the basket. Then I retrieved the pf from its bath and put the basket into it. Proceeded to make and drink the shot. No problems. One less step to go through for me.

Sure! Three (3) feet above sea level; 44% humidity; 78 degrees F ambient/room temperature; and taste buds with at least 43 years of enjoying coffee (out of 49 years of age) due to being a grandson of coffee growers and roasters.

It is always good to experiment with variables (e.g., different doses; different temperatures; different pressures; etc.). What could taste "amazing" to someone might taste "awful" to someone else.

I think it is time to start using a kettle showing 1/10s of a degree. 205.5F may be the sweet spot, assuming all other variables remain constant...

vit wrote:Yes, it was in Flair temperature study thread, I was indeed quite enthusiastic after getting a great temperature measurement with very flat end, similar to some graphs on boiler espresso machines, which was well above my expectations. So I wanted to challenge some Robot owners to do something similar on their machines, didn't expect that Paul was also checking that thread and he didn't like the challenge. My apologies for that


I believe you have completely misinterpreted my posts. I have never said I dislike the challenge. I strongly welcome you and anyone to play, experiment do side by side comparisons or whatever you see fit, but please do so under fair and consistent conditions. The whole "let's see if Robot users can beat that" post is quite inflammatory since I nor anyone with a machine that I know of has attacked or belittled any other manual machine, and as I said before I most certainly have not cherry picked any videos.

I agree with Paul. And I think it's time to return this discussion to the use of the Robot specifically. If you want to discuss the merits of the Flair or the Flair versus the Robot in some odd match-up, then please start a different thread.

That is cool!

BTW - the Robot has intense WAF. She lives the look of it and the discussions it fosters at dinner parties. Whereas the geeks like the GS3 and Versalab and the profiling modifications, everyone raves and wants to see the robot in action.
Caution! Water, heat, pressure and electricity don't mix! I want an espresso.
