I enjoy making my own cocktail bitters, which involves steeping things like herbs, roots, barks, rinds, and more in high-proof alcohol for a few weeks, and then straining the mixture. The filtration of loads of teeny, tiny particles has always been a slow part of the process (using gravity and cheesecloth, for example). Until now. I grabbed my AeroPress coffee maker and started using it as the high-pressure filtration piston that it really is.
