I think i've said it before and i'll quote it again. Turkish Coffee short, sweet, strong, and simple
I did as you suggested and you are correct sir. The foamy stuff floating on top of the french press brew is quite bitter.The crema in espresso is not just carbon dioxide gas, it's also an emulsion of coffee oils produced by the high pressure of the espresso machine, that's why it has a great flavour. That's completely different to the foam on french press which is basically just carbon dioxide gas released by hot water hitting the coffee, there's not much in the way of flavour from it. It would also contain bits of extracted coffee that have floated to the top, which again, would detract from the final taste rather than add to it. Next time you make a french press, drink the foam you scooped off and you can taste that it isn't the same as crema from espresso.
After shimming the kg79, the fine, consistent grind it produces is working very well for me.Been perusing this thread and others the last few days.
A KG79 is order of the day I think and some sort of Espresso machine. A Gaggia would be nice but De Longhi seem to be up there
