For those that make multiple batches of coffee each day using some type of pourover, aeropress, or drip machine, do you ever try to reuse the paper filter from one brewing to the next? Seems like a smart approach if you want to minimize paper taste, save a few pennies, or be green.
I never gave that a second thought before trying the aeropress, where the instructions encourage trying that approach. Still, for the longest time I never tried doing that with any other brewing method until a few months ago. At first I thought rather than heat so much water to rinse the filter, why not first rinse it out with cold water, which then led to the thought of rinsing out the prior grounds and starting over. I have gotten good results reusing the hario branded filter a 2nd and 3rd time, by scooping out most of the grounds for the compost bin, then rinsing the remainder out. I haven't tried this with my v-shaped dripper, as the filters I have are not as sturdy.
