Hoping for some help here... I have had my Oracle for 12 months and on a whole have been fairly happy, although none of my extractions have been anything like Phil's videos. I get my beans in reasonably small lots from a roaster in Melbourne. I have just opened a batch of Sumatran Blue Batak which is about 3 weeks old and my coffee making has fallen off a cliff. I am not familiar with this variety and have just been working through the available menu. It is very burnt smelling and I cant get the grind fine enough (under 1) to get an extraction that lasts longer than about 23 seconds for 30 mls (and it tastes bitter and burnt)
I cleaned the machine within an inch of its life and just swapped with some generic store bought beans as a trial and the result is not a whole lot better - grind is on 4 and I am just chewing through beans. Just don't know where to turn. Is anybody familiar with this bean variety - what is the characteristics? I don't fancy shelling out $20-30 for beans and postage if I don't know what the issue might be.
Any pointers gratefully accepted.
Thanks,
Grant
