Hey coops, that's great to know you can do this.

Actually, I don't (yet) have any coffee cups that fit under the group handle - so I am still using the OTTO mug/pourer to catch the extraction.

On a separate note, I have just picked up a pair of 9oz/270mL Bodum Pavina thermal glasses. They have dual walls. They seem to overcome the issue of keeping the extraction warm while I steam the milk. They look great too. This is my effort from this morning.



On another note, I have been thinking about your earlier post and started to change a few more things with the beans that have been giving me problems. Success! :cheer: I used the espresso basket and ground as fine as I could and then increased the dosage from 16 to 20g. Tamped as normal. I got about 60mL of extraction, with plenty of crema and the steaming pressure was great! Now to chart it... ;)

A quick question for all you OTTO owners.

I am noticing a dark build up inside the group handle (underneath the basket). Although I wash the group handle and the basket out after each extraction I am still seeing a gradual build-up. The build-up makes the inside of the group handle smells like very stale coffee and can't be doing anything good for the shots I pull.

My questions are:
- is anyone else noticing this build-up?
- if so, how are people attempting to clean it?

So far I am using ordinary detergent and a roughish sponge to clean it, and it takes forever to move the build up - and I cannot remove it entirely.

Any and all suggestions welcome.

I don't have an Otto, but I notice the same thing with the portafilter on my machine. My solution is to soak the PF, shower screen, group head, etc. in a detergent for espresso machines. I try to do this once a month. Makes everything look as good as new.

Hi Allan
I also see the build up, I clean the basket and portafiller after every shot. (I am currently using 5 times a day)
I was going to try lemon juice or a vinegar solution. The surface is quite rough so a place for an oil film to stick.
I will do it now and see how it goes.....

Thanks Brokemusician77, a good suggestion. Is there anything special about detergent for espresso machines?

Hi Coops, thanks for checking that out. I also noticed the rough surface, and had the same thought as you (a perfect place for oils to stick).

While you have your machine apart, have a look at the actual hole the extraction comes through. I noticed some rifling (spiral grooves) that help to direct the flow of liquid. Cleaning those is also difficult. I worked on mine with a wooden toothpick, but I am not convinced I got everything out of there. I probably just loosened everything for the next shot! :laugh:
