Cherub temperature - to surf or not??

Recommended Posts

With 2 new valves on the boiler my Cherub is now holding pressure like never before - thanks forum for the help!!

I have always noticed that when pulling 2 consecutive shots, the 2nd shot tend to flow considerably slower. I accurately weigh and dose my coffee and try to tamp consistently. I assume this is a temperature issue? Or not? Do anyone temperature surf their Cherub? I guess I could do that and see if it changes the flow, but wonder if anyone else have this issue?

Time 200ml water out the group twice. See if theres any difference? 

May rule out everything on the user side. Or may not.

Could be retention on your grinder giving a mix of fresh & old grounds on your first shot.
