Bleached, Natural, Square, Circle, Half-Moon, pre-folded, unfolded...
At long last I've fallen in love with a 10-cup chemex, more than any other pourover method I've tried so far. I'm using natural prefolded squares. I can't keep from wondering: Is there really much difference between all these filter options, and why would someone want bleached paper when natural is an option?
I also understand that the half-moon is only for the narrow 3-cupper, but does it perform as well as its big siblings? Do chemex lovers love single cups in the smallest chemex as much as they love their cups from shared batches in the big brewers?
I have yet to put a chemex filter in my V60 cone as even when I'm only brewing for myself, i just enjoy the clear glass. But I'm also of the mind that the flat glass and the way the filter adheres might be beneficial to its performance, whereas the ridged interior of the V60 prevents such flush adhesion and might possibly allow faster/exterior draining or cooling. Plus the thickness of the paper vs the smallness of the V60 hole could have the opposite problem -- too slow to drain. I guess the question is, is a chemex brew purely about filter performance (therefore potentially the same no matter what cone holds the filter), or does the upper cone design of the brewer also play an important part?
And finally -- if all chemex filter paper is created equal, is there still a particular shape some people prefer for use outside the chemex brewer, i.e. in a V60 or other cone? The half-moon, the circle, the square?
