advice please
I'm having some problems with my extractions after changing from the original SB double basket. I have switched to the 15 g VST basket.
My grinder is the Breville smart pro-BCG 820
My coffee machine is the Sunbeam EM 7000
I changed to the new VST baskets to improve my coffee flavour,
I have not worked out how to control the coffee flow using the recommended coffee weight for the 15 g basket, It would seem to get any sort of control of the flow rate I need to overfill the basket to something like 22 g. If I do not do this the beverage will just gush out of the portafilter.
I have also had to decrease my grind to an incredible low adjustment of one. (With the old SB double filter I could easily choke my EM7000) I have not worked out a way to choke my machine using the VST basket = Not that I want to do that, it's just that if I could then would be able to work out a range with which I can work to find that sweet spot.
I am nearly the but am left with no adjustment with my grinder (and I'm also wondering if this is completely wrong being set at one) previous setting with SB double basket was 8
Best I have achieved so far using a grinder setting is one and with a progressive tamp and loading the 15 g VST to 22 g, (at 22g the grind is just touching the filter screen after expansion) I can achieve a very good beverage flow rate from the portafilter but only lasting 20 seconds. The flow rate starts to speed up at about 15 seconds and way to fast after 25 seconds. If I stop the flow at 20 seconds it has delivered nearly 40 mils for a triple shot espresso. I have run out of adjustment on the grinder and it is incredibly fine.
If I add less coffee grind it just turns up as soup in the portafiler and gushes out. Also using extreme force tamping while using a courser grind the coffee gushes out. This lead me to using a low setting on the grinder. The odd thing is the original SB baskets worked at the expected range 8
I'm not to worried about the gauge on the EM7000 but the flow rate from the portafilter spout
Excuse me for the long explanation but can anyone provide ideas which could help lead me to getting the 15 g VST dialled into my Sunbeam EM7000 - would be appreciated.
Thanks
