Is there a quantifiable difference to the taste or coffee brewed with bleached, unbleached or natural fibre filters? Or would you use one over the other for ecological or economical reasons?

I would assume this would be the same to some degree across all filter brewing methods.

    I asked a similar question about brown vs. white filters; does that answer your question? Also: can you clarify what you mean by natural fibre: do you mean like bamboo or cotton cloth as opposed to unbleached (brown paper)? Here's another about paper vs. not-paper filters.

This could depend on the brand of filters and the brewing method so it's worthwhile (and fun) to do the experiment. I'd love to see results from more experimenters.

Bamboo vs. Paper Filters: I did this experiment. We only had three tasters but the results were statistically significant at the 5% standard -- all three of us could taste the difference. The bamboo filter made sharper coffee (analogous to sharp cheese) while the paper filter made smoother coffee. We did not all have the same preference between those two batches.

Filtering out Diterpenes: According to the AeroPress FAQ question "DO YOU RECOMMEND USING A METAL FILTER IN THE AEROPRESS?":

We were originally planning to include a metal filter with each AeroPress but when we conducted blind taste tests comparing paper filtered AeroPress brewed coffee with metal filtered AeroPress brewed coffee, the paper filtered coffee always won.

We also learned using a paper filter is healthier because it removes diterpenes from coffee and diterpenes are potent agents that raise your bad cholesterol.

Q. Does anyone know if bamboo filters similarly remove the diterpenes from coffee? Are bamboo filters made from a combination of paper and bamboo fibers?
