Profitec Pro 800 shot volume

What are people usually seeing for their shot volume with the Pro 800? I have noticed on mine it usually tops out around 30-35ml.

Not sure if it's 100% the same spec, but on the L1 I just got a little over 40ml by volume when releasing the lever after the first drop hit the cup, i.e. puck was fully saturated and waiting a couple minutes for crema to settle. So 30-35ml seems in the ball park.

If you do a search you will find varying info on this? Here is an example

and here another one

I'm using my own roasts of El Salvador Finca Kilimanjaro and SM's La Tacita Floral Giesha Blend. I'm using 16 grams in and getting 40 ml out (1.5 ounces) using an Espresso Parts 14 gram basket. Adding 12 ounces of steamed milk for a lattes. Results have been very consistent - day after day. PID is set to 246F yielding just a bit over 1 bar boiler pressure. Edited - changed 30ml to 40ml.

Water absorption of the coffee used, the dose, pre-infusion time, technique/pressure etc. all influence the reply to your question so unless you're more specific it will be hard to compare the result. The common denominator seems to be the group is capable of doing a double shot.

The volume of the Pro 800 cylinder is close to 60ml and that will weigh about 60 grams. The percentage of that which makes it into the shot depends on how complete the preinfusion is and how long the shot runs.

Am I correct in understanding that with levers such as the Pro 800 or a Bosco, if one wants, say, 30g in the cup, you essentially have to move the cup from under the group and continue extracting into the drip tray?

Isn't there a less messy way of controlling shot volume?

In a word, yes.

It's not really messy, especially if the (commercial) machine is plumbed-in and -out as designed. And if you want to keep the blonded extraction from going into the drip tray, just substitute a waste cup under the spout when you pull your shot away.

EDIT p.s. Please don't pull the portafilter off before the spring lever has returned to its resting position. Anyone who has done so will have done so exactly once. And talk about a mess!

Removing the cup after the desired volume is the only way to control the shot volume.

Why is that messy?That is exactly what the drip tray is for.
