Subject: 1st time with Bottomless PF on CC1
 

Here is a vid of my first time with my new PF on my new CC1.  This coffee was only roasted on the day before so it was a fast frothy shot.  I didn't realize you get so much more air (bubbles) and volume in the crema with a bottomless.  I had only one small spurt which I am sure I can fix quickly.  This shot was only about 25 seconds.  Any helpful hints or suggestions?

I would grind a little finer.  I have mine dialed in really well with 16g and using Redline.  I got my bottomless PF and OE dosing funnel last Saturday, makes a big difference.

The only thing I don't like isn't there is a lot less mass on the naked PF so it does not stay hot well.

Also, have you had any issues with the puck sticking to the shower screen?  I have used 19g before and didn't have that issue but now even at 16g it has happened a couple of times.  I have a 20g VST basket and a CC brass handled tamper on the way.  Been using the stock tamper.

No issues with the puck sticking to the screen.  It does seem like my group gasket is weird though.  It seems too loose sometimes, then tight, etc.  Annoying.  I am going to try my convex tamper next time i do a pull to see how it changes.

Try shooting from a bit lower angle and don't frame it so  that bright window is in the background.

 
I play go. I use Macintosh,. Of course I ride a recumbent.

You've still got a super bright spot in the shot. That affects the auto exposure negatively.

Nice pull, though. I'm having a fabulous time with my new naked filter. I need a stainless steel mirror. I did not really believe so many subtle things could affect the pour so dramatically.

Can happen on any machine, happened to me a few times as well. Can be anything from the grind, to beans, blend type, dose etc.. wouldn't worry about it long as the shot taste fine. Lower doses happen more frequently as there's less "stick" to the basket, I'm right around 16g doses as well. For the bottomless, what I do and most any other user with a machine with a bottomless does, do a blank flush like 1oz right before you put the grinds in the basket (just dry it the basket quickly with a little towel).

Aquanin - try grinding a little finer. Have you tried preinfusing yet, play around with it, I use preinfusion everyday.

With a bottomless portafilter the espresso only touches the basket so I'm not sure that's very important.

 
If it ain't broke, fix it 'til it is.

I tried going finer but I got something like 24g of yield from 17g in the basket.  There is a bunch more air in the crema with the bottomless.  This morning I tried to actually go a little coarser and ended up with what looked like 2.5oz in the cup but there was a lot of air in the crema.  The taste was super smooth ans sweet!!! I did 2 sec pre, 2 sec wait, and 30 sec total brew time.

Here is what I mean by my group gasket leaking.  This is with the Machine heated up, PF locked in tight.
