I did several tests with IPA, Everclear, Vodka, and Tequila, including the lime step. I have not yet consumed the results, but I did do a STB test of the lime-tannin mixture that settled to the bottom of my jars with lime, just to try to see how much (if any) DMT may have settled out alongside the tannins.

To do this, I mixed in enough NaOH to bring the ph up to 13, then mixed in some naptha and then freeze-precipitated the naptha. FWIW, none of these yielded any noticeable amount of DMT, which *hopefully* means the vast majority of the DMT stayed in the top layer while the tannins separated and sank with the lime.  These were all on a magnetic stir hotplate starting with 200g MHRB and 200ml of alcohol, but I also have some tests started using the "room-temp, sit for weeks" approach. I'll post back here once I test/drink the results.
