LMSC Thank you for your advice but, unfortunately, yes, I do need to compromise. It’s called marriage! 😀
The fundamental difference is that a B2C uses pressure while a filter does not. One system relies on pressure (that requires higher temperatures and finer grinds), while the other system relies on infusion.
There are three main variables, in coffee brewing:
Temperature
Surface area
Time
Filter coffee brewers and B2C coffee makers vary these three according to different philosophies.
