I just became interested in pour-over coffee, after a lifetime of only drinking mokas. While shopping for my first coffee machine, i noticed that there are two kinds of coffee filters: bleached and unbleached, apparently the only difference between them is just the color, but i'm sure there's something i'm missing.
Both are fine, for most any good coffee, you'll have an equally good time if you give the unbleached filter a pre-rinse with hot water. But if you're venturing into Very Expensive Fancy Coffee (like $30 > per 100g), unbleached is probably the way to go to not have to worry about the flavour mixing.
