I just put some Cosmorex decaffeinated beans through my Silivia grinder / machien combo - they seem much more dry than the previous beans (Ethiopian Fair Trade organic sun dried coffee I got off eBay) which seem much more oily.
With the Ethiopian beans I find if I put too much in the (double dose Australian) basket it is very difficult to latch the group head to the machine and it leaves a dimple from the bolt - i.e. it seems too full - and the resulting coffee is quite bitter after it drips very slowly through. It is a very fine line between tapping the group head a few times to fit more grind in, and too much and getting too much grind in that seems to overdose it and is hard to press down and latch in.
Yet it is fine line to under-dosing with the tell tale signs of a wet puck with pooling water, and bitter rapidly blonding pour.
However the de-caf bean grind I am now trying seem more light brown in colour and more dry - and the resulting coffee is very water and quite bitter as it blondes almost immediately with little crema.
I can try overdosing it and tamping it right down, or going for a finer grind. Any thoughts?
