Subject: That sounds a bit unusual.
 

Here in Arizona during the summer the weather can go from dry to wet and back again a few times in any given summer day. At first I was suspecting you might be seeing the results of a similar weather change. For example, all my grinders required (what I would call) a significant adjustment this morning to get the same pours I was getting yesterday.

I make it a point to wipe my screen with a dry rag before each shot and get varying amounts of moisture and coffee off each time, so I was thinking this is what you are experiencing. However, it sounds like you have more moisture than any atmospheric change could account for.

Here's the thing- If you have some sort of leak then the pump would most likely come on at some point to refill the boiler. Can you leave it on long enough without it going to sleep and see if the pump comes on occasionally with out you pulling shots? Leave a shot glass under the porta filter and see what it collects over time.

Also, try back flushing without chemical. Do you get a lot of coffee grounds when you're finished? Maybe there are grounds that need to be cleaned out. Heck, do a chemical auto-clean too, that might help if you have a physical particle in the way somewhere.

As Donner said, I wouldn't sweat (sorry, couldn't resist) it too much if your shots are tasting/pulling right. I hope you get it worked out with a few cleaning cycles. I'm no espresso tech, rather I'm just sharing some thoughts on what could be happening with your machine, good luck!

Jay sometimes my portafilter is dry and sometimes it's got a bit of collected water in it. It usually depends on what the environment is like in my home.  The only thing that I would worry about is if the group head is leaking, meaning a seal somewhere in the brew path is bad.  To test this turn the machine on, leave the portafilter off, and make sure everything around the machine is dry. Then place a dry paper towel on top of the drip tray and leave it there for a while, if you come back and the paper towel is wet now you know it's not condensation, if you come back and the paper towel is dry then you know it is!

I think the difference between the A and the B models is the B portafilter has larger lugs and creates a tighter seal at the grouphead, this would support the condensation hypothesis as there is less heat/air transfer in the new model.

Subject: baratza preciso for breville dual boiler
 

hi everyone im thinking of getting a preciso, although i have a vario i want to pull different beans and i dont want to mess with 1 setting with another so i decided to get another grinder. so im eyeing on preciso for its manual pour over grinds.

so i want to know if anyone here is using preciso and does it serve well for the dual boiler? can it choke the bdb?

thanks

I have left it on for about half a day, but it did not seem like it came back on after going into hibernation.
I will try and clean for testing.
It was like this the first day I got it as a replacement, so I am assuming it wasn't the cleaning issue.

I will definitely try and see if it is a leak problem or not.
Thanks

Preciso is up to it. I have one that I don't use every day, but it's a solid grinder and at least one reviewer thought it produced more consistent grind than the Vario.

Have used the Preciso with an Esatto scale since I purchased my Breville 900. All three are still working today. I note the esatto can be a bit off in it's estimation of stop point, when I change different coffees with widely different grind weight / volume, but its something that can be worked with.  (And it's still far easier than using a separate scale on every cup.) To be exact, the esatto sometimes under weighs the grind - this can be compensated for by just depressing the grind start button. If the difference is sufficient (a light weight to set point) it then grinds to set point.

Subject: Different baskets
 

I am considering getting a vst basket just to play with. my primary goal is to try lower doses of coffee and see what flavor profiles I get...

With the stock single-walled baskets, I am using 19-20g in the double and 17g in the single to get reasonable extractions. This dosing is partially (largely, I suppose) dictated by the fact that I need to put enough grinds into the basket to be able to tamp without bottoming out along the taper. The single basket, with its tiny extraction screen/small open area, is particularly difficult to dial in.

In your experience, which vst baskets have you found to be most successful, and at what doses? Or, do you have any suggestions for more traditional, straight-walled, non-vst baskets that accommodate lower doses while maintaining a reasonable headspace?
